Answer: .10d+.25q<_ 4
Step-by-step explanation:
d= dimes and q = quarters
dimes are worth .10 and quarters are worth .25
The inequality for the given situation is
0.1d + 0.251 ≤ 4
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
10 dimes = 1 dollar
1 dime = 0.1 dollar
4 quarters = 1 dollar
1 quarter = 0.25 dollar
Now,
The maximum amount is $4.
So,
0.1d + 0.251 ≤ 4
Thus,
The inequality is 0.1d + 0.251 ≤ 4.

Malik solved this system of equations.
2 x + 4 y = 24. 5 x + y = 15.
As the first step, he decided to solve for x in the first equation because it has a small, even number for the coefficient. Jill told him there was a more efficient way. What reason can Jill give for her statement?
The variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 5 so it will be easy to divide 15 by 5.
The variable y in the first equation is divisible by 2 so it will be the most efficient way to start.
The variable y in the first equation has a larger even number. When dividing by 4, the solution will be a smaller number.
The reason Jill give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution. Hence, option A is the correct statement.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
System of equations
Given the simultaneous equation;
2x+4y=24
5x+y=15
The best way to solve this kind of system of equation is by the substitution method.
Then To do that in an easy way, we can locate which of the variables in the equations has a coefficient of 1.
From the second equation, we can see that the variable "y' has a coefficient of 1.
Therefore, the reason that Jill can give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.
Hence, option A is the correct statement.

Help please....I have no idea what I’m doing
Answer:
C) 8
Step-by-step explanation:
Use the formula
Slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]y_1[/tex] - any y value
[tex]x_1[/tex] - x value corresponding to y_1
similarly, you can pick y_2 and x_2 from the table.
Pick any two rows
Let's pick row 3 and 4
Slope = [tex]\frac{33-23}{5-3}[/tex]
=> 10/2
Slope = 5
Now formula
y = slope * x + intercept
y = 5x + intercept
intercept = y - 5x
Now take any row from the table and substitute above to calculate intercept
Taking row 3
intercept = 23 - 5 * 3
intercept = 8

Ali, Ben, and Cliff plant seedlings in their neighborhood park. Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. If Cliff plants 87 seedlings, how many seedlings do the three boys plant altogether?
Answer:
580 seedlings altogether.
Step-by-step explanation:
Given that,
Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.
The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
Let x = the total number of seedlings
[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]
Hence, three boys plant 580 seedlings altogether.

Given is the piecewise function.
It has three different pieces.
The first piecef(x) = 2, with x ≤ -2Plot the point (-2,2) and draw a horizontal line to the left from this point
The second piecef(x) = 1/2x + 3, at the interval -2<x≤1Plot two border points at x = -2 and x = 1:
f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)and
f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)Connect these two points with a line segment
The third piecef(x) = -7/8x + 35/8, at x > 1Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)
f(1) = -7/8*1 + 35/8 = 28/8 = 3.5and
f(5) = -7/8*5 + 35/8 = 0Connect the two points (1, 3.5) and (5, 0) and extend the line to the right
Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.

Ms. Mwanted to estimate the height of the Republic Plaza building in downtown Denver. She has an app on
her phone that will measure an angle of elevation. She determined she was 100 feet from the base of the
building. She held her phone (with the app) at eye level (about 5 feet off the ground) and measured the angle
of elevation to the top of the building to be 82°. What is the height of the building to the nearest foot?
Answer:
The height of the bullding is 717 ft
Step-by-step explanation:
Right Triangles
The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.
The tangent ratio for an internal angle A is:
[tex]\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.
The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:
[tex]\displaystyle \tan 82^\circ=\frac{h}{100}[/tex]
Solving for h:
[tex]h = 100\tan 82^\circ[/tex]
Computing:
h = 711.5 ft
We must add the height of Ms, M's eyes. The height of the building is
711.5 ft + 5 ft = 716.5 ft
The height of the building is 717 ft
In the given parallelogram, BELT,find the value of p,q,x,y
Answer:
5. x = 10, y = 6 6. p = 60°, q = 120°, x = 60° , y = 30°Step-by-step explanation:
5.
2x = 20 ⇒ x = 10
5y + 5 = 35 ⇒ 5y = 30 ⇒ y = 6
6.
m∠T = x = 180° - 90° - 30° = 60°
m∠E=m∠T ⇒ y = 180° - 90° - 60° = 30°
m∠B = m∠L = q = 180° - m∠E = 180° - 60° = 120°
m∠B = 30° + p + y ⇒ p = 120° - 30° - 30° = 60°
If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?
1/9
2/3
54
96
Answer:
2/3
Step-by-step explanation:
you can set it up as x/y because it varies directly
so when y=6 x=72
72/6 = 12
so x will always be 12 times greater than y
x=12y
so if x=8
8=12y
y=8/12
y=2/3
