400Let x = the number 10% of x = 400.10 x = 400.10x/0.10 = 40/0.10x = 400 check:10% of 400 = 400.10 * 400 = 4040=40
Answer:
Step-by-step explanation:
30*20%= 6 so $6.00 tip
Total with tip is $36.00
Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
Hope it helps!
Answer:The formula looks like this: SA=2lw+2lh+2hw, where SA = surface area, l = length, w = width, and h = height. In the rectangular prism net above, l = 8 inches, w = 5 inches, and h = 3 inches.
