Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.
The +100 at the end is why we don't have a proportional equation.
Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.

Olivia is 4 feet 10 inches tall. She compared her height with her younger
sister, Susan, and found that Susan is 15 inches shorter than she is. What is
Susan's height, in inches?
Answer:
Step-by-step explanation:
4 feet = 48 inches, add 10 inches = 58 inches
if susan is 15 inches shorter, 58- 15 = 43

The local sporting goods store sells footballs at the following rate.
Number of Footballs n Total Price t
2 $17.00
4 $34.00
Use the chart above and the following information to answer the true and false questions that follow. The sporting goods store also sells baseballs at a 50% of the cost of the footballs. Determine which of the following statements are true. Select True or False for each statement.
10. The price of 6 baseballs is less than the price of 4 footballs. True or False
11. The difference in the price of 1 football when compared to the price of 1 baseball is less than $3
12. The price of 3 footballs is equal to the price of 6 baseballs. True or False
Answer:
True, False, True
Step-by-step explanation:
Calculate the unit price of a football and a baseball
2 footballs cost $17.00 , then
1 football costs $17 ÷ 2 = $8.50
A baseball is 50% of a football, thus
cost of base ball = 50% of $8.50 = 0.5 × $8.50 = $4.25
(10)
4 footballs cost $34.00 ( given in table )
6 baseballs cost 6 × $4.25 = $25.50 < $34
Thus 6 baseballs < 4 footballs is True
(11)
The difference in price = $8.50 - $4.25 = $4.25
Thus the difference in price is greater than $3, not less False
(12)
3 footballs cost 3 × $8.50 = $25.50
6 baseballs cost 6 × $4.25 = $25.50
Thus the costs are equal is True

Which statements are true about triangle XYZ? Select three options.
XY measures units.
YZ measures units.
ZX measures units.
XYZ is a right triangle.
XYZ is a scalene triangle.
First, second and fourth options are true about triangle XYZ.
XY measures [tex]\sqrt{26}[/tex] units.
YZ measures [tex]\sqrt{52}[/tex] units.
ZX measures [tex]\sqrt{26}[/tex] units.
XYZ is a right triangle.
What is right triangle?A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
Given X (-1, 5), Y (4, 4), Z (-2, 0)
Distance between two points D = [tex]\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1}) ^{2}}[/tex]
|XY| = [tex]\sqrt{(4-5)^{2} +(4+1)^{2} } =\sqrt{1^{2}+5^{2} } =\sqrt{26}[/tex]
|YZ| = [tex]\sqrt{(0-4)^{2} +(-2-4)^{2} } =\sqrt{4^{2}+6^{2} } =\sqrt{52}[/tex]
|XZ| = [tex]\sqrt{(0-5)^{2} +(-2+1)^{2} } =\sqrt{5^{2}+1^{2} } =\sqrt{26}[/tex]
[tex]|XY|^{2} +|XZ|^{2} =|YZ|^{2}[/tex]
So, XYZ is a right triangle.
So, the first, second and fourth options are correct.

Answer:
V = 0.8 in^3
Step-by-step explanation:
Formula:
V = πr^2(h/3)
C = 2πr
Given:
h=11.1
C = 17.6
C = 2πr
17.6 = 22πr
0.8/π = r
V = πr^2(h/3)
V = π(0.8/π)^2((11.1)/3)
V = π(0.0648455575)(3.7)
V = 0.8 in^3

The true statements of the rectangle are as follows:
The other sides of the rectangle measures 4 inches and 12 inches. The perimeter in cm can be found using the expression (2×12)(2×4)The area can be found by multiplying 12 cm by 4 cm.The statements that are true in the option are highlighted with point listing.
The other sides of the rectangle measures 4 inches and 12 inches.Generally a rectangle has 2 opposite sides equal to each other.
The perimeter in cm can be found using the expression (2×12)(2×4)The perimeter of a rectangle can be express as follows:
perimeter = 2l +2w
where
w = width
l = length
The area can be found by multiplying 12 cm by 4 cm.The area of a rectangle can be express as follows

Meredith borrows $12,560 and pays 2% simple interest each year for 4 years. What is the total amount of interest that she will pay on the loan?
Answer:
A = $13,564.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.
Solving our equation:
A = 12560(1 + (0.02 × 4)) = 13564.8
A = $13,564.80
The total amount accrued, principal plus interest, from simple interest on a principal of $12,560.00 at a rate of 2% per year for 4 years is $13,564.80.

Answer:
33.51
Step-by-step explanation:
There's a formula using the value of the angle but I don't remember it so the most easy way is:
A circle has an angle of 360°
so our section has an angle of 60
and we know that 360=60*6
so the area of the circle we divide it by 6 and we get the area we want
[tex]A=\pi r^2\\\\A=\pi (8)^2\\\\A=64\pi[/tex]
divide this by 6
[tex]A_1=A/6=64\pi/6\approx 33.51[/tex] units squared
