Aretha is correct. Since a rhombus a is a quadrilateral with 4 equal sides in terms of length, (forming 4 right angles in each corner), it can be concluded that all squares are rhombuses. However, only some and not all rhombuses are squares because some rhombuses may have equal lengths but all corners don't form right angles.

Question
Since Marnie has bought her car,the value has gone down 15%.If her car is 13000 right now,how much was it worth when she bought it?
Solution 1
Percentage of depreciation of the car that Marie bought = 15%
Present value of the car = 13000
Let us assume that the value of the car at the time of buying = x
So
The percentage valuation of the car now = (100 - 15) percent
= 85 percent
Then
(85/100) * x = 13000
85x = 13000 * 100
85x = 1300000
x = 1300000/85
= 15294.12
So the actual cost of the car is 15294.12. I hope the procedure is clear enough for you to understand.
Question
The municipal swimming pool in Nicetown has three different ways of paying for individual open swimming. Todd is trying to decide which way to pay. • Early Pay: Pay $70 before Memorial Day; swim any number of days • Deposit Plus:$15 deposit plus $4.00 per day • Daily Pay:$6.00 per day Answer the following questions: 1. Write an equation for each method of payment. Write your equations in slope-intercept form so that x is the number of days and y is the cost. a. Early Pay: b. Deposit Plus: c. Daily Pay:
Solution 1
Sllope intercept form is y=mx+b
m is the slope , b is the y itnercept

so early pay
cost=70 flat rate
x=infinity
the equation would be y=70

deposit pluss
you have to pay an initial one time payment of 15 so
y=mx+15
then 4 dollars per day
4 times number of days
y=4x+15

daily pay is 6 dollars per day so 6 times number of days
y=6x

1.
a. y=70
b. y=4x+15
c. y=4x
Question

The length of the bedroom is 13 feet. The area of the bedroom is 175.5 square feet. How wide is my sister's bedroom? A. 13.5 ft B. 13.5 ft 2 C. 162.5 ft 2 D. 198.5 ft 2 Solution 1 Area = length x width Given: length = 13 , area = 175.5 175.5 = 13 x width width = 175.5 ÷ 13 width = 13.5 feet The width is 13.5 ft (Answer A) Solution 2 Since the formula for the area of a rectangle is length × width = height, we can divide the area by the length to get the width. 175.5 ÷ 13 = 13.5 And since the width is one dimensional, the answer is A.
