Answer:
The length of rectangle is 16 meters and the width of rectangle is 7 meters
Step-by-step explanation:
Let
L -----> the length of the rectangle
W ---> the width of the rectangle
we know that
The perimeter of rectangle is equal to
----> the perimeter of a rectangle is twice the sum of its length and its width
we have
so
simplify
-----> equation A
----> equation B
substitute equation B in equation A and solve for W
Find the value of L
therefore
The length of rectangle is 16 meters and the width of rectangle is 7 meters

A.
Step-by-step explanation:
Not reasonable, Why did you put that as your answer?
The whole numbers add up to more then 4 cups.
Sub
105=700*0.05*t
105=35t
divide both sides by 35
3=t
t=3
Answer:
Step-by-step explanation:
The trick here is when do the discounts take place? The "buy 1 get 1 half off" must take place before the total is computed to get the 20% off.
So she spends
First pair of socks: 20
Second Pair: 20 - 10 = 10
Hoodie: <u> 20</u>
Total: 50
Now she gets another 20% off which means that she still pays 80% of her purchases. (80 / 100) * 50 = 4000/100 = 40 dollars which is ultimately what she spent.
She saved a total of 10 + 10 = 20 dollars.
The % discount is (20 / 60 (which is what she should have paid) ) * 100
The % discount = 1/3 * 100 = 33.3 %
