Answer:
1 pound of jelly beans cost $1.75 , 1 pound of trail mix cost $3.75
Step-by-step explanation:
let j represent 1 pound of jelly beans and t represent 1 pound of trail mix , then
5j + 3t = 20 → (1)
7j + 9t = 46 → (2)
multiplying (1) by - 3 and adding to (2) will eliminate t
- 15j - 9t = - 60 → (3)
add (2) and (3) term by term to eliminate t
(7j - 15j) + (9t - 9t) = 46 - 60
- 8j + 0 = - 14
- 8j = - 14 ( divide both sides by - 8 )
j = [tex]\frac{-14}{-8}[/tex] = 1.75
substitute j = 1.75 into either of the 2 equations and solve for t
substituting into (1)
5(1.75) + 3t = 20
8.75 + 3t = 20 ( subtract 8.75 from both sides )
3t = 11.25 ( divide both sides by 3 )
t = 3.75
then
cost of 1 pound of jelly beans = $1.75
cost of 1 pound of trail mix = $3.75
Answer:
Cost for each pound of jelly beans: $1.75
Cost for each pound of trail mix: $3.75
Step-by-step explanation:
Define the variables:
Let J be the cost of one pound of jelly beans.Let T be the cost of one pound of trail mix.Using the given information and defined variables, create a system of equations:
[tex]\begin{cases}5J+3T=20\\7J+9T=46\end{cases}[/tex]
To solve the system of equations, multiply the first equation by 3 to create a third equation:
[tex]5J \cdot 3+3T \cdot 3=20\cdot 3[/tex]
[tex]15J+9T=60[/tex]
Subtract the second equation from the third equation to eliminate the term in T:
[tex]\begin{array}{crcrcl}&15J & + & 9T & = & 60\\\vphantom{\dfrac12}- & (7J & + & 9T & = & 46)\\\cline{2-6}\vphantom{\dfrac12} &8J&&&=&14\end{array}[/tex]
Solve the equation for J by dividing both sides by 8:
[tex]\dfrac{8J}{8}=\dfrac{14}{8}[/tex]
[tex]J=1.75[/tex]
Therefore, the cost of each pound of jelly beans is $1.75.
To find the cost of one pound of trail mix, substitute the found value of J into one of the original equations and solve for T.
Using the second equation:
[tex]7(1.75)+9T=46[/tex]
[tex]12.25+9T=46[/tex]
[tex]12.25+9T-12.25=46-12.25[/tex]
[tex]9T=33.75[/tex]
[tex]\dfrac{9T}{9}=\dfrac{33.75}{9}[/tex]
[tex]T=3.75[/tex]
Therefore, the cost of each pound of jelly beans is $3.75.

When we solve the radical equation, we can see that the value of x is -113.
What is a radical equation?A radical equation is an equation in which one or more variables are under a radical sign, such as a square root, cube root, or higher-order root. These equations involve expressions with radicals that contain the variable, and the goal is usually to isolate the variable on one side of the equation.
Given that;
10 + √2x + 1 = -5

circles.
Give your answer in terms of TT.
6cm
30cm
14cm
The diagram is not drawn to scale.
The perimeter of the given shape in terms of pi is 22 cm + 25 pi cm.
How do you figure out perimeter?The circumference of the rectangle is equal to the sum of the lengths of its four sides. It is simple to do this because there are two of each side length; all that is needed is to sum the length and width and multiply the result by two.
By multiplying half of the semicircle's circumference by the diameter's length, one can determine the semicircle's perimeter. Thus, the semicircle's perimeter is as follows:
Perimeter of semicircle = 6 cm + (1/2) x pi x 6 cm
Perimeter of semicircle = 6 cm + 3 pi cm
Each quarter circle has a perimeter that is just one-fourth of its circumference. Consequently, the 14 cm quarter circle's perimeter is as follows:
Perimeter of quarter circle with radius 14 cm = (1/4) x 2 pi x 14 cm
Perimeter of quarter circle with radius 14 cm = 7 pi cm
And, the perimeter of the quarter circle with radius 30 cm is:
Perimeter of quarter circle with radius 30 cm = (1/4) x 2pi x 30 cm
Perimeter of quarter circle with radius 30 cm = 15 pi cm
Therefore, the total perimeter of the given shape is:
Perimeter = Perimeter of semicircle + Perimeter of quarter circle with radius 14 cm + Perimeter of quarter circle with radius 30 cm
Perimeter = (6 cm + 3 pi cm) + (7 pi cm) + (15 pi cm)
Perimeter = 22 cm + 25 pi cm.

y = 8 +0.75x.
(a) Find the inverse function.
(b) What does each variable represent in the inverse function?
(c) Determine the number of units produced when your hourly wage is $22.25.
(1) The inverse function is: [tex]f^-1 (y)[/tex] = (y - 8)/0.75 (2) In the inverse function, y represents the number of units produced and x is the hourly wage.(3) an hourly wage of $22.25 is approximately 14.93.
How do you know if a graph is a function?If a vertical line drawn anywhere on the graph of a relation only intersect at one point on the graph, then this graph represents a function. If a vertical line can intersect the graph at two or more points, the graph does not represent a function.
(a) To find the inverse function, we must solve for x in terms of y.
y = 8 + 0.75x
y - 8 = 0.75x
x = (y - 8)/0.75
So the inverse function is:
[tex]f^-1 (y)[/tex] = (y - 8)/0.75
(b) In the inverse function, y represents the number of units produced and x is the hourly wage.
(c) To determine the number of units produced when the hourly wage is $22.25, we need to plug y = 22.25 into the inverse function we found in part (a):
[tex]f^{-1}[/tex](22.25) = (22.25 - 8)/0.75
[tex]f^{-1}[/tex](22.25) = 14.93
Therefore, the number of units produced at an hourly wage of $22.25 is approximately 14.93.

Find the value of y in the figure above. Leave your answer in simplest radical form.
The value of y in the triangle is 20.
What is the triangle?
A triangle is a polygon with three sides and three angles. It is the simplest and most basic polygon in Euclidean geometry.
According to the given information:
From the figure, we can say that ΔABC and ΔABI are similar.
we can write proportions as
[tex]\frac{y}{30} =\frac{30}{y+25}[/tex]
y(y+25) = 30*30
[tex]y^{2}[/tex]+25y=900
[tex]y^{2}[/tex]+25y-900 = 0
On solving we can use quadratic formula y = (-b ± √(b^2 - 4ac)) / (2a)
For the given equation y^2 + 25y - 900 = 0, we can identify a = 1, b = 25, and c = -900.
Plugging these values into the quadratic formula, we get:
y = (-25 ± √(25^2 - 4 * 1 * -900)) / (2 * 1)
Simplifying further:
y = (-25 ± √(625 + 3600)) / 2
y = (-25 ± √(4225)) / 2
y = (-25 ± 65) / 2
Now we can solve for two possible values of y:
y = (-25 + 65) / 2 = 40 / 2 = 20
y = (-25 - 65) / 2 = -90 / 2 = -45
So the two possible values of y that satisfy the given equation are y = 20 and y = -45.
distance cannnot be negative, so the value of y is 20.

A) 8x⁶
Step-by-step explanation:Exponents have different rules for operations such as multiplication.
Multiplying Coefficients
When multiplying different terms with exponents, the first thing we should do is multiply the coefficients. Even though there are variables with different exponents, we still multiply the coefficients like normal. This means that the coefficient of the answer should be 8 because 4 * 2 =8. However, you should note that you can only multiply the coefficients and simply the expression if the terms have the same variable.
Multiplying Exponents
To multiply 2 terms with exponents, you should add the exponents together. For example, x⁴ * x⁶ = x¹⁰. No matter what the coefficients are, if the variables are the same, then this method will work. This means that x³ * x³ = x⁶. Then, combine this with the coefficient from before and 4x³ * 2x³ = 8x⁶.

Answer:
x = 16°
Step-by-step explanation:
What we know:
∠JML = 47°
∠JKL = (7x + 21)°
∠JML is an inscribed angle
∠JKL is an inscribed angle
Inscribed angles are half of the value of their intercepted arc
So if m∠JML = 47° then mArc JL is double that or 94°
And ∠JKL is intercepted by Arc JML which is the rest of the circle not intercepted by ∠JML so
mArc JL + Arc JML = 360°
94 + Arc JML = 360
Subtract 94 from both sides to isolate Arc JML
Arc JML = 266°
So if Arc JML = 266° then it's intercepted inscribed angle is half of that.
Arc JML ÷ 2 = ∠JKL
266 ÷ 2 = ∠JKL
133 °= ∠JKL
Now we can use this value and set it equal to the expression to find the value of x
(7x + 21) = 133
Subtract 21 from both sides to isolate the x
7x = 112
Divide both sides by 7
x = 16

if n = 4 then σ(4)=1+2+4=7 and H4 = 1+1/2+1/3+1/4. Solve this equation to either prove or disprove the following inequality n≥1? Does it hold for all n≥1?
Using the method of mathematical induction, we show that the inequality σ(n) > H(n) holds for all n≥1. Thus, the inequality n≥1 is true for all n≥1.
What is mathematical induction?It is a a technique used in mathematics to prove that a statement is true for every positive integer or natural number. It consists of two steps:
Base case: Prove that the statement is true for the first positive integer (usually 1).Inductive step: Assume that the statement is true for some arbitrary positive integer k, and then prove that it must also be true for the next positive integer (k+1).We can calculate like this:
Base case: Show that the inequality holds for n=1.
When n=1, we have σ(1) = 1 and H1 = 1, so the inequality 1 ≤ 2^(σ(1)/H1) becomes 1 ≤ 2^(1/1), which is true.Inductive hypothesis: Assume that the inequality holds for some arbitrary positive integer k, i.e., k ≤ 2^(σ(k)/Hk).
Inductive step: Show that the inequality also holds for k+1. Consider σ(k+1) and H(k+1). We can express them as σ(k+1) = σ(k) + k+1 and H(k+1) = H(k) + 1/(k+1).
Using the inductive hypothesis, we have:
k ≤ 2^(σ(k)/Hk),So, we can raise both sides to the power of (k+1)/(kH(k+1)) to get:
k^(1/(kH(k+1))) ≤ 2^((k+1)/(kH(k+1)) * σ(k)/Hk).By the AM-GM inequality, we know that σ(k+1)/k+1 ≥ H(k+1), so we can replace the denominator (kH(k+1)) with H(k+1) and simplify to get
k^(1/H(k+1)) ≤ 2^(σ(k+1)/H(k+1)).Therefore, we have shown that k+1 ≤ 2^(σ(k+1)/H(k+1)), which means the inequality holds for all positive integers n by mathematical induction.

A 3 scoops ice-cream cone cost 4.80. A single Scoop ice-cream cost $2. Which one cost less for each scoop of ice cream ? How much less?
A single scoop is $0.40 cheaper per scoop than a scoop in a 3-scoop cone.
To compare the cost of each scoop of ice cream in a 3-scoop cone and a single scoop, we need to calculate the cost per scoop for each option.
In a 3-scoop cone, the cost of each scoop can be found by dividing the total cost by the number of scoops. Therefore, the cost of each scoop in a 3-scoop cone is:
4.80 ÷ 3 = 1.60
On the other hand, a single scoop of ice cream costs $2. Therefore, the cost of each scoop in a single scoop is:
2 ÷ 1 = 2
Comparing the two options, we can see that a single scoop of ice cream costs less per scoop than a 3-scoop cone. Specifically, a single scoop is $0.40 cheaper per scoop than a scoop in a 3-scoop cone.
Therefore, choosing a single scoop of ice cream over a 3-scoop cone will result in a cost savings of $0.40 per scoop.
In conclusion, when comparing the cost per scoop of ice cream, a single scoop is cheaper than a scoop in a 3-scoop cone. The cost savings per scoop is $0.40.

Lighthouse B is 9 miles west of lighthouse A. A boat leaves A and sails 4 miles. At this time, it is sighted from B. If the bearing of the boat from B is N65degreesE, how far from B is the boat? Round to the nearest tenth
(Note: Needs 2 Answers)
PLEASE HELP I'M GOING INSANE
*please include work/formulas for every step when needed*
Boat is 4.195 miles or 6.749755 km far from the lighthouse B.
How to find the distance?The boat has moved 4 kilometers from point A to point x. The distance between B and x is what we're looking for.
Trigonometry can be used to overcome this issue. Let's abbreviate the distance "d" from A to x. Then, we can apply the following formula:
tan(65°) = (9 / d)
We can rearrange this formula to solve for d:
d = 9 / tan(65°)
We find that:
tan(65°) = 2.1445
So, d = 9 / 2.1445
= 4.195 miles (rounded to the nearest tenth)
or 6.749755 km.
Hence, Boat is 4.195 miles or 6.749755 km far from the lighthouse B.

Jake and his friends
are bowling. The area of
the rectangular lane is 14x2-x-3
square feet. If the width of the lane is
2x -1 feet, write an expression to
represent the length of the lane.
SOLUTION:
Answer:
L = (14x^2 - x - 3) / (2x - 1)
Step-by-step explanation:
The area of the rectangular lane is given as 14x^2 - x - 3 square feet.
Let's assume that the length of the lane is L feet. Then the formula for the area of a rectangle is:
Area = Length x Width
Substituting the values given in the question, we have:
14x^2 - x - 3 = L x (2x - 1)
To find an expression for the length of the lane, we can rearrange the equation to solve for L:
L = (14x^2 - x - 3) / (2x - 1)
Therefore, the expression that represents the length of the lane is:
L = (14x^2 - x - 3) / (2x - 1)
jenny earned a 77 on her most resent test. jennys score is no less than 5 points greater than 4/5 of terrance score if t represents terrances score which is the inequality represents the sisuation.
Answer: Jenny's score is no less than 5 points greater than 4/5 of Terrance's score.
Step-by-step explanation:
The inequality that represents the situation described is:
Jenny's score (denoted as "J") is no less than 5 points greater than 4/5 of Terrance's score (denoted as "T"):
J ≥ (4/5)T + 5
In this inequality, we are saying that Jenny's score "J" must be greater than or equal to 4/5 of Terrance's score "T", plus an additional 5 points. This reflects the condition that Jenny's score should be at least 5 points higher than 4/5 of Terrance's score.
For example, if Terrance's score "T" is 80, then 4/5 of Terrance's score is (4/5) * 80 = 64. Adding 5 points to this gives us 69. Therefore, Jenny's score "J" must be greater than or equal to 69 in this case, since it should be no less than 5 points greater than 4/5 of Terrance's score.
What is the vertical displacement of the basic graph to produce a graph of
y =pi-3 cos(x-2)?
The value of D represents the vertical displacement or shift of the basic cosine graph. Therefore, the vertical displacement of the given graph is pi - 3.
What is Displacement?
In physics, displacement refers to the distance and direction of an object's change in position from its starting point. It is a vector quantity that measures the overall change in position of an object, regardless of the path it took to get there. Displacement can be positive, negative, or zero depending on the direction and distance of the movement.
To find the vertical displacement of the basic graph to produce a graph of y = pi - 3 cos(x - 2), we need to compare the given equation with the general cosine function y = A cos(Bx - C) + D.
Here, A = 3, B = 1, C = 2, and D = pi - 3.
The value of D represents the vertical displacement or shift of the basic cosine graph. Therefore, the vertical displacement of the given graph is pi - 3.

We can rewrite sin⁸x in terms of first powers of the cosines of multiple angles as:
sin⁸x = 1/128 (35 - 4cos²x + 40cos⁴x - 64cos⁶x + cos⁸x)
What is power reducing formula?Trigonometric functions raised to powers can be rewritten using double-angle, half-angle, and Pythagorean identities in power lowering formulas. Equations can be made simpler using them, and trigonometric expressions can be precisely determined.
We can use the power-reducing formulas to rewrite sin⁸x in terms of cosines of multiple angles as follows:
sin²x = 1 - cos²x (first power-reducing formula)
sin⁴x = (sin²x)² = (1 - cos²x)²
= 1 - 2cos²x + cos⁴x (second power-reducing formula)
sin⁶x = (sin⁴x)(sin²x)
= (1 - 2cos²x + cos⁴x)(1 - cos²x)
= 1 - 3cos²x + 3cos⁴x - cos⁶x (third power-reducing formula)
sin⁸x = (sin⁶x)(sin²x)
= (1 - 3cos²x + 3cos⁴x - cos⁶x)(1 - cos²x)
= 1 - 4cos²x + 6cos⁴x - 4cos⁶x + cos⁸x
Now we can substitute the expression for sin⁸x into the given expression and simplify it:
1/128 (35 - 56 cos2x + 28 cos4x - 8 cos6x + cos8x)
= 1/128 (35 - 56(2cos²x-1) + 28(4cos⁴x-3cos²x) - 8(8cos⁶x-8cos⁴x+cos²x) + cos⁸x)
= 1/128 (35 - 112cos²x + 56 + 112cos⁴x - 84cos²x - 64cos⁶x + 64cos⁴x - 8cos²x + cos⁸x)
= 1/128 (35 - 4cos²x + 40cos⁴x - 64cos⁶x + cos⁸x)
Therefore, we can rewrite sin⁸x in terms of first powers of the cosines of multiple angles as:
sin⁸x = 1 - 4cos²x + 6cos⁴x - 4cos⁶x + cos⁸x
= 1/128 (35 - 4cos²x + 40cos⁴x - 64cos⁶x + cos⁸x)
