What is the value of the ratio of the surface area to the volume of the right prism? A.
0.39

B.
0.82

C.
0.97

D.
1.04

Answers

Answer 1

Answer: The main formula of the surface area of a right prism is A = 2 x (w x h + l x w + l x h) , where w=7, l=8, and h=4, so the surface area value is A=2(7x4+8x7+8x4)=2(28+56+32=2x116=232. Besides, the volume of a right prism can be calculated with the formula V= l x w x h =8x 7x 4 = 224. Finally the ratio of the surface area to the volume is A / V= 232 / 224 = 1.04. the true answer is D

Which statement best describes the expression 3y ÷ 8?8 divided by 3 times y
8 times y divided by 3
3 divided by 8 times y
3 times y divided by 8

Answers

3 times y divided by 8

(the last answer)

Because "3y" comes first and then "÷ 8" so the order is correct with 3 times y divided by 8, and the others can be ruled out.

a hardcover book sells for $24 at the Bookmart. Ben pays a total of $25.02 for the book. What is the sales tax rate?

Answers

The rate of sales tax on the hardcover book is 4.25%.

Given that, a hardcover book sells for $24 at the Bookmart.

What is the sales tax?

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Ben pays a total of $25.02 for the book.

So, sale tax =25.02-24

= $1.02

Now, the sales tax rate

= 1.02/24 ×100

= 0.0425 ×100

= 4.25%

Hence, the rate of sales tax on the hardcover book is 4.25%.

25.02-24=1.02
1.02/24=.0425
So the sales tax rate is 4.25%
