Step-by-step explanation:
At the donut shop the cost for a dozen donut holes and a glass of milk is $3.50. The cost for three dozen donut holes and four glasses of milk is $11.80 which pair of equations can be used to determine D (the cost for donut holes) and M (the cost for the milk)
Answer:
Step-by-step explanation:
12 D + M = 3.50
3*12 D +4M = 11.80
the pair of equations are
12 D + M = 3.50
36 D +4M = 11.80

Please help. How do you find cosine, sine, cosecant and secant with this triangle?
Hi there! You have to remember these 6 basic Trigonometric Ratios which are:
sine (sin) = opposite/hypotenusecosine (cos) = adjacent/hypotenusetangent (tan) = opposite/adjacentcosecant (cosec/csc) = hypotenuse/oppositesecant (sec) = hypotenuse/adjacentcotangent (cot) = adjacent/oppositecosecant is the reciprocal of sinesecant is the reciprocal of cosinecotangent is the reciprocal of tangentBack to the question. Assuming that the question asks you to find the cosine, sine, cosecant and secant of angle theta.
What we have now are:
Trigonometric RatioAdjacent = 12Opposite = 10Looks like we are missing the hypotenuse. Do you remember the Pythagorean Theorem? Recall it!
a²+b² = c²Define that c-term is the hypotenuse. a-term and b-term can be defined as adjacent or opposite
Since we know the value of adjacent and opposite, we can use the formula to find the hypotenuse.
10²+12² = c²100+144 = c²244 = c²Thus, the hypotenuse is:
[tex] \large \boxed{c = 2 \sqrt{61} }[/tex]
Now that we know all lengths of the triangle, we can find the ratio. Recall Trigonometric Ratio above! Therefore, the answers are:
cosine (cosθ) = adjacent/hypotenuse = 12/(2√61) = 6/√61 = (6√61) / 61sine (sinθ) = opposite/hypotenuse = 10/(2√61) = 5/√61 = (5√61) / 61cosecant (cscθ) is reciprocal of sine (sinθ). Hence, cscθ = (2√61/10) = √61/5secant (secθ) is reciprocal of cosine (cosθ). Hence, secθ = (2√61)/12 = √61/6Questions can be asked through comment.
Furthermore, we can use Trigonometric Identity to find the hypotenuse instead of Pythagorean Theorem.
Hope this helps, and Happy Learning! :)

Find the area of the composite figure.
Answer:
Area of composite figure = 623.25 cm²
Step-by-step explanation:
Given:
Equal side of triangle = 39 cm
Diameter of semi-circle = 30 cm
Base of triangle = 30 cm
Find;
Area of composite figure
Computation:
Radius of triangle = 30 / 2
Radius of triangle = 15 cm
Height of triangle = √39² - 15²
Height of triangle = √1,521 - 225
Height of triangle = 36 cm
Area of composite figure = Area of semi-circle + Area of triangle
Area of composite figure = [πr² / 2] + [(1/2)(b)(h)]
Area of composite figure = [(3.14)(15)² / 2] + [(1/2)(15)(36)]
Area of composite figure = [(3.14)(225) / 2] + [(15)(18)]
Area of composite figure = [706.5 / 2] + [270]
Area of composite figure = 353.25 + 270
Area of composite figure = 623.25 cm²
7/2h-3(5h-1/2)
I ALSO NEED STEP BY STEP INSTRUCTIONS NO WEBSITES OR SCREENSHOTS TYSM
Answer:
the simplified expression of this is -23/2h + 3/2 or -11 1/2h + 1 1/2.
Step-by-step explanation:
7/2h - 3(5h - 1/2)
3(5h - 1/2)
First, we need to use the distributive property to distribute the expression which requires multiplication or division. We take 3 and multiply it by both values in the parentheses which gives us 15h - 1/2. However, since there is subtraction, we need to do the opposite of that which would be 15h + 1 1/2 or 15h + 3/2. Now we can't forget 7/2h at the beginning of the expression. Here is the remaining expression :
7/2h - 15h + 3/2 or 7/2h - 15h + 3/2
Now, we need to combine like terms which requires values to have the same variable. 7/2h and 15h have the same variable so combine like terms. We do subtraction.
7/2h - 15h
We subtract this and get a result of -23/2 or -11 1/2 but don't forget the variable.
-23/2h
1/2 doesn't have a variable so we no longer can combine like terms. Therefore, it would just be -23/2h + 3/2 or -23/h + 1 1/2.
A studio apartment has a floor that measures 120 feet by 60 feet. A scale drawing of the floor on grid paper uses a scale of 1 unit : 6 feet. What are the dimensions of the scale drawing?
Answer: [tex]20\ \text{unit}\times 10\ \text{unit}[/tex]
Step-by-step explanation:
Given
A studio apartment has a floor that measures [tex]120\ ft \times 60\ ft[/tex]
Scale used is 1 unit:6 feet i.e 6 feet of actual floor is considered 1 unit in drawing
The dimension of scale drawing is [tex]\frac{1}{6}[/tex] of actual
Dimensions are
[tex]\Rightarrow \dfrac{120}{6}\times \dfrac{60}{6}\\\\\Rightarrow 20\ \text{unit}\times 10\ \text{unit}[/tex]
Which of the following expressions is equal to squared +25? O A. (x+5012 O B. (x-50 O C. (x + 10 (x-151) O D. (X - 5)(x+51)
Answer:
(x-5i)(x+5i)
Step-by-step explanation:
Given the expression
(x-5i)²
Expand
(x-5i)(x+5i)
= x² - 5ix + 5ix - 25i²
= x² - 25i²
Since i² = -1, hence;
(x-5i)(x+5i) = x² - 25(-1)
(x-5i)(x+5i) = x² + 25
Hence the required expression is (x-5i)(x+5i)

The hypotenuse of a right triangle is one inch longer than the longer leg. The shorter leg is seven inches shorter than the longer leg. Find the length of the hypotenuse.
Answer:
Length of hypotenuse is 13 unit or 5 unit
Step-by-step explanation:
Find;
Length of hypotenuse
Computation;
Assume;
Length of hypotenuse = h
Length of longer leg = h - 1
Length of shorter leg = h - 1 - 7
Using Pythagorean theorem
hypotenuse² = longer leg² + shorter leg²
h² = (h - 1)² + (h - 1 - 7)²
h² = (h - 1)² + (h - 8)²
h² = h² - 2h + 1 + h² - 16h + 64
h² = 2h² - 18h + 65
h² - 18h + 65 = 0
h² - 13h - 5h + 65 = 0
h(h - 13) -5(h - 13)
(h - 13)(h - 5)
So,
Length of hypotenuse is 13 unit or 5 unit
1. Which graph represents the inequality y < 4?
Answer:
The third one.
Step-by-step explanation:
What is the solution of y= 4x + 6 when y= 18?
Answer:
18 = 4(3)+6
12 + 6
Step-by-step explanation:
the answer is 18 = 4(3)+6
because y is 18
Answer:
x=3
Step-by-step explanation:
[tex]18 = 4x + 6[/tex]
subtract 6 on both sides
[tex]12 = 4x[/tex]
divide both sides by 4
[tex]3 = x[/tex]

The sketch shows two parallel lines cut by a transversal. Which pair of angles are alternate interior angles?
Answer:
B) Angle 5 and angle 4
Step-by-step explanation:
Given
See attachment for sketch
See comment for options
Required
The alternate interior angles
Interior angles are such that they are located between the given parallel lines.
In the attached sketch, the interior angles are: 3, 4, 5 and 6
Alternate angles are at the opposite sides of the transversal
Hence:
4 and 5 are alternate interior
3 and 5 are also alternate interior

If the cylinder above is similar to a second cylinder that has a radius of 10mm, what is the height of the second cylinder
Answer:
The height of the second cylinder is 30mm
Step-by-step explanation:
Given
Cylinder 1:
[tex]R = 15mm[/tex]
[tex]H = 45mm[/tex]
Cylinder 2
[tex]r = 10mm[/tex]
See attachment
Required
Determine h, the height of the small one
To do this, we make use of the following equivalent ratios;
[tex]R : H = r : h[/tex]
This gives:
[tex]15 : 45 = 10 : h[/tex]
Express as fraction
[tex]\frac{15 }{ 45 }= \frac{10 }{ h}[/tex]
Simplify
[tex]\frac{1 }{ 3}= \frac{10 }{ h}[/tex]
Cross multiply
[tex]h *1 = 3 * 10[/tex]
[tex]h = 30[/tex]
A bank makes a profit of 20 million euro. The bank pays 500 thousand euro in tax. What percentage of the profit is paid in tax?
Answer:
2.5%
Step-by-step explanation:
Given data
Profit = Euro 20,000,000
Tax paid= Euro 500,000
The percentage tax paid is
% Tax= Tax paid/Profit*100
% Tax= 500,000/20,000,000*100
% Tax=0.025*100
% Tax=2.5
Hence the percentage tax paid is 2.5%

Answer:
12 feet
Step-by-step explanation:
48 divided by 4 is 12 and 48 is the total area
Answer:
12 sq. ft.
Step-by-step explanation:
To find the area of a square (or rectangle) you multiply the length by the width.
To find the length of one side, when you have the area and one side, you divide the area by the side you have.
48 divided by 4 equals 12.
