Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p
Nick had 14 jelly beans in a bag. His mother put a handful of jelly beans in the bag. When Nick counts his jelly beans, he discovers he now has 28 of them. Which of the following equations will help Nick solve for the number of jelly beans, j, that his mom put in the bag?
14j = 28
14 + 28 = j
14 + j = 28
j − 14 = 28

Answer:
1. 108.375 2. 76.765625
Step-by-step explanation:
1. We have the s-value now, which is 4.25.
Plug it in to the equation for surface area:
6*(4.25)^2
6*4.25*4.25
Using a calculator, we get 108.375
2. Plug 4.25 in to the equation for volume:
(4.25)^3
4.25*4.25*4.25
Using a calculator, we get 76.765625

Joyce goes walking on a track shaped like the solid line in the diagram shown. Find the total area enclosed by the track.
A. 2,956.5 square meters
B. 2,250 square meters
C. 3,309.75 square meters
D. 2,826 square meters
Answer:
A
Step-by-step explanation:
πr^2
π * 15^2 = 706.858347
75 X 30 = 2250
706.858347 + 2250 = 2956.858347
The total area enclosed by the track is 2956.5 square meters
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The given figure has one rectangle and two semicircles
The area of rectangle is length times width
Area = length × width
=75×30
=2250 square metres
Area of circle is πr²/2
=3.14×15²/2
=706.5/2
=353.25
As there are two semicircles = 2×353.25
=706.5
Total area is 2250+706.5 which is 2956.5 square meters
Hence, the total area enclosed by the track is 2956.5 square meters

Answer: A) The relationship is proportional because the ratio of m to k is constant.
______________________________________________________
Step-by-step explanation:
17.699 ÷ 11 = 1.609
41.834 ÷ 26 = 1.609
&
54.706 ÷ 34 = 1.609

The three equations above equal 1.609 making the relationship between m & k constant.

A rectangle has a length that is 9 inches less than twice its width. The area of the rectangle is 180 square inches.
a. Write an equation that represents the situation.
b. Find the length and width of the rectangle.
c. Find the perimeter of the rectangle.
pls help lols
Answer:
Step-by-step explanation:
a) Let the width = w
Two times its width = 2*w = 2w
9 inches less than 2w = 2w - 9
Length = 2w - 9
Area of rectangle = length *width = 180 square inches
(2w - 9 ) * w = 180
2w*w - 9*w = 180
2w² - 9w - 180 = 0
b) sum = -9
Product= -360
Factors = -24 , 15 {15 *[-24] = -360 and 15 + (-24) = -9 }
2w² - 9w - 180 = 0
2w² - 24w + 15w - 180 = 0
2w(w - 12w) + 15(w - 12) = 0
(w -12) (2w + 15) = 0
{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}
w - 12 = 0
w = 12 inches
l = 2w -9
= 2*12 - 9
= 24 - 9
l = 15
length = 15 inches
Width = 12 inches
c) Perimeter = 2 *(length + width)
= 2*(15 + 12)
= 2 * 27
= 54 inches
