Step-by-step explanation:
Answer:
A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

How many ½-foot unit cubes can be added to fill the prism completely?
Use what you know about unit cubes or the side lengths of prisms to show your work or explain your answer.
Answer:
Each cube with side lengths of 1/4 have a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.

Find the constant of proportionality for the table of values and write in the form y = kx
A) y = 1/4x
B) y = 4x
C) y = 6x
D) y = 24x
Answer:
Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of lemons used is denoted by 'y'.
Number of glasses of lemonade is denoted by 'x'.
As we can observe that ,
[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]
so we can write i as
[tex]\frac{x}{y} = \frac{1}{4}[/tex]
By cross multiplication
y=4x
So, if write it in the form y=kx,
It will be y=4x.
Select the correct expanded form for (Two-thirds) Superscript 4.
Two-thirds times two-thirds times two-thirds times two-thirds
Two-thirds times two-thirds times two-thirds
Two-thirds + two-thirds + two-thirds + two-thirds
Two-thirds times 4
Answer:
A
Step-by-step explanation:
The exponent 4 means it is 2/3 multiplied by itself 4 times.
So it would be 2/3*2/3*2/3*2/3

Which of the following statements are true? Select all that apply.
The radius of a circle is twice its diameter.
The radius of a circle is twice its diameter.
The formula to find area of a circle is A=πr2
To find the diameter of a circle, divide its circumference by π.
The circumference of a circle is greater than its diameter.
To find the diameter of a circle, multiply the radius by 2.
The diameter can be used to find area of a circle.
Answer:
Step-by-step explanation:
By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. ... The length of the diameter is twice that of the radius. Therefore, all diameters of a circle are congruent, too.

The regular price of a brand new pair of shoes is $72. When using a
coupon the price went down to $54. What was the percent off on the
coupon used?
A.15%
B.25%
C.75%
D.50%
Answer:
C. 75%
Step-by-step explanation:
hope this helped
I mainly just did the math of each percentage and 72
(calculator was used)
Answer:
B. 25%
Step-by-step explanation:
Part/Whole
54/72=0.75
75% was the amount left over ($54), meaning 25% of the coupon was used ($18).
Checking Answer:
72/4=18. 18 is 25% of the pair of shoes. 25% is 4 less then 100%, so lets pretend 100 is replaced with the number 72. What is 4 times less then 72? 18. If 75% of the coupon was used, then you would use 18(3)=54, since three would stand for 25% three times used from the coupon which is 75%, the remaining 25% being 18.

PLS HELP SHAWTIES !!!!!!!
Answer:
Formula of circumference: pie(use 3.14 or 22/7) x radius (half of diameter or already given radius) x 2
100 + 100 = 200.
Half of 50(diameter) is 25(new radius). 25(radius) x 3.14(pie) x 2(it always will be there when finding circumference) = 157.
200 + 157 is = 357.
357 is your answer.

How can the addition porperty of equality be used to solve substraction equations? (Please answer correctly)(no links)
Answer:
just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.
by-step explanation:
x+7=42
Since 7 is being added to the variable, subtract 7 to isolate the variable.
To keep the equation balanced, subtract 7 from both sides of the equation.
x+7=42
-7 over x+0
-7 over 35
so answer is 35
