Answer:
The quantity is 12
Step-by-step explanation:
Here, we want to find the solution to the equation.
Let the quantity we are looking for be x;
According to the question;
The quantity plus a quarter of the quantity = 15
x + 1/4(x) = 15
x + x/4 = 15
Multiply through by 4
4x + (x/4)*4 = 15 * 4
4x + x = 60
5x = 60
x = 60/5
x = 12
Answer:
top one is correct, it is 12!

Scott has 3 erasers and 4 pencils in his bag. Write a part-to-whole ratio for the number of pencils Scott has in his bag?
Answer:
4:7
Step-by-step explanation:
So to find the whole part of this ratio we need to add 3 and 4 which equals 7
Then the part of this ratio is the number of pencils- 4
So the part to whole ratio is 4:7
4 times the sum of 8 and a number is 32. What is that number?
Step-by-step explanation:
let the unknown be x
4(8 + x) = 32
32 + 4x = 32
4x = 32 - 32
4x = 0
x = 0 ÷ 4
x = 0
if you wanna check,
4(8 + 0)= 32
32 + 0 = 32
32 = 32
hope I got it right&^^,good luck!

Write the equation of a line that is perpendicular to y = -8 3 x + 4 and goes through the point (5, 2)
Answer:
y = 3/8x + 1/8
Step-by-step explanation:
The slope of a perpendicular line is the opposite and reciprocal of the original slope.
-8/3 -> 3/8
Find the new y-intercept.
y = 3/8x + b
2 = 3/8(5) + b
2 = 1.875 + b
0.125 = b
y = 3/8x + 1/8

what is the constant of proportionality?
Answer:
B, 0.625
Step-by-step explanation:
The constant of proportionality is y/x
from the equation y = kx -> y/x = k
Answer:
c 1.6
Step-by-step explanation:
The constant of proportionality is what determines the relationship between y and x. If r is the constant of proportionality then an example is y = rx . The value of y is dependant on how the given value of x is effected by the constant of proportionality.

Angle 1 = 120
Step-by-step explanation:
(4x + 40) = (2x + 80)
4x + 40 = 2x + 80
2x + 40 = 80
2x = 40
x = 20
2(20) + 80
40 + 80
120
Angle 1 is a vertical angle from (2x + 80) so they have the same measurement.
Fuji apples cost $3.00 per pound, and Golden Delicious apples cost $2.00 per pound. A childcare center purchases 30 pounds of a combination of the two types of apples for a total of $80. Which value could replace x in the table?
A. 30 – g + g
B. 3(30 – g)
C. 30 – g(3)
D. 30 – g + 3
Answer: B: 3(30-G)
Step-by-step explanation:
A following table titled Apples showing Pounds, Cost per Pound and Total.
This means that
1 pound of Fuji apples costs $3
(30 - g) pounds of Fuji apples cost
The total is 3(30-G)

Tom performs a dilation of ⅓ on a triangle. He then classifies the image and pre-image as being congruent. Is Tom correct? Why or why not?
Answer: Tom is incorrect.
Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.
In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.

Step-by-step explanation:
What is the y-intercept of the function f(x)=4 - 5x?
-5
-4
4
5
Answer:
The y-intercept is 4. The third option is correct
Explanation:
The equation of a line is written as:
y=mx+b
Where m is the slope and m is the y-intercept or the point where y crosses the x-axis.
The given function is f(x)=4-5x.
It can be rewritten as
f(x)=-5x+4.
We can recognize the slope m=-5 and the y-intercept b=4
First option: Incorrect. The y-intercept is not -5
Second option: Incorrect. The y-intercept is not -4
Third option: Correct. The y-intercept is 4
Fourth option: Incorrect. The y-intercept is not 5
The y-intercept of the equation f(x) = -5x + 4 is 4.
How to find the y-intercept from slope intercept equation?The y-intercept is the value of y when x = 0.
The slope intercept equation can be express as follow:
y = mx + bwhere
m = slope
b = y-intercept
Therefore, let's model the equation f(x) = 4 - 5x to the slope intercept form.
f(x) = -5x + 4
Therefore, according to the slope-intercept equation, the slope is -5 and the y-intercept is 4.
The y-intercept is the value of y when x = 0.

A=4ℼR2 solve for R
SHOW ALL STEPSSSSSSSSSSSSS
Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by [tex]\frac{1}{4\pi }[/tex]
A x [tex]\frac{1}{4\pi }[/tex] = [tex]\frac{1}{4\pi }[/tex] x 4 π R²
[tex]\frac{A}{4\pi }[/tex] = R²
Then find the square root of both sides

Using translation concepts, it is found that function g(x) is defined by:
[tex]g(x) = \left|\frac{x}{5}\right|[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The absolute value parent function is defined by:
f(x) = |x|
When it is strecthed horizontally by a factor of 5, it means that the domain is divided by 5, hence the function is given by:

Answer:
B. 12.43 ft
Step-by-step explanation:
cosine = adjacent / hypotenuse
cos 43° = y / 17
multiply both sides by 17
17 (cos 43°) = y
cos 43° = 0.7314 (use your calculator)
y = 17 x 0.7314
y = 12.43 ft.
