Answer:
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50
Step-by-step explanation:
Let
x ---> amount that William has at the beginning
y ---> amount that Gracie has at the beginning
we know that
William says to Gracie, "If you give me $7.50,we will have and equal amount of money
so
----> equation A
"Grace responds, if you give me $ 7.50 instead, I will have twice as much money as you
----> equation B
substitute equation A in equation B
solve for x
Find the value of y
therefore
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50
She needs to purchase a cover to protect the hot tub of an area of 38.5 square feet.
<h3>What is a circle?</h3>
It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub.
The area of the circle is given by
We have d = 7 ft, then the area of the circle will be

Answer:
1)1920 in2 (2)120 in3
Step-by-step explanation:
First question, the answer is C. 2nd question, the answer is A
Explanation: I don’t know how to well explain graphs.. however, on the vertical line, that’s the amount of money the person pays after the amount of months they’ve started their plan. Whether that be beginner, or veteran. If you look, the lines overlap a month which is month 4. This is where they both pay 100$, this is because the 100 lines up at that point. For the 2nd question, the beginner would have paid lower than the veteran because the line is below the first. Hope this helps!
Answer:
a) The perimeter of a rectangle is written as:
P = 2*L + 2*W
where L is the length amd W is the width (broad in this case).
here we have:
L = 8cm and W = b
then the perimeter is:
P = 2*8cm + 2*b
And we know that:
18cm ≤ P ≤ 50cm
where ≤ is used because there is written "not more" and "not less", so the equalities are allowed
now we can replace P by the above equation:
18cm ≤ 16cm + 2*b ≤ 50cm
now we can subtract 16cm in each side and get:
18cm - 16cm ≤ 2*b ≤ 50cm - 16cm
2cm ≤ 2*b ≤ 34cm
Now we can divide each side by 2.
1cm ≤ b ≤ 34cm/2 = 17cm
1cm ≤ b ≤ 17cm.
b) Here we have missing information, so this can not be answered.
(only knowing that one side length is x, and another side length is x + 3cm, we can know that x > 0cm, so the minimum value of x is really close to 0cm)
