answer:

B) 58.88 inches^2

Steps:

You need to find the area BETWEEN a big circle and a small circle. So you need the areas of the circles first. The big circle of radius 2.5 + 2.5 = 5 with a smaller circle of radius 2.5 inside.

The area of a circle is pi*radius^2 so the area of the big circle is 25pi and the area of the small circle is 6.25pi. So the area in between the big circle and the small circle is 25pi - 6.25pi = 58.88 inches^2 (choice B)

Solve for x in the diagram below. Numerical answer only, no units

DiKsa [7]

Answer:

12

Step-by-step explanation:

Since it is on a right angle we can equation the sum of both angles to 90:
6x-2+20 = 90

Now we simplify:

6x+18=90

Now we subtract 18 from both sides:

6x+18-18=90-18

Simplify:

6x=72

Now we divide both sides by 6:

6x÷6=72÷6

Simplify:

x = 12

The table shows a set of values for x and y

Lesechka [4]

a) Assume y = $x^{2}$

$1b=\frac{k}{1^{2} }$ k = 1b

$y=\frac{1b}{x^{2} }$

b) y = 25

$x^{2}=\frac{16}{25}$

$x=\sqrt{\frac{4}{5} ^{2} }$

x = ± $\frac{4}{5}$

x > 0, x = 4/5
