It is 88 because you times both top and bottom with the same number the denominator should equal to a 100. <span />
The zero of this function is 10.2564103 ( or 10 if you round it) because you need to substitute d with 0. The value of this context means the maximum amount of trading cards you can get with the gifts card

Answer:
x=20
Step-by-step explanation:
Look Angle A and D are Congruent so they equal the same
3x−10=2x+10
Subtract 2x from both sides
3x−10−2x=2x+10−2x
x−10=10
Add 10 to both sides.
x−10+10=10+10
x=20

Answer:
88
Step-by-step explanation:
First find the area of the fountain using the area formula of a circle.
The formula for area is
. Here the radius is 5 ft. So the area is
.
We will subtract the area of 78.5 from the larger circle of the brick path and fountain to find only the area of the brick path.
The larger circle has an area of
where the radius is 9ft.
Subtract to find the area of the path: 254.34 - 78.5 = 175.84. Divide this area by 2 to find the number of bricks needed since each brick is 2 square feet.
175.84/2 = 87.92 = 88 bricks
