Belle made a scale drawing of a mural where 2 inches of the drawing represents 3 feet on the actual mural (scale 2 in. = 3 ft.). In real life, the mural is 6 feet tall and 18 feet wide. What is the area of her drawing in square inches?

Answers

Answer:

Very sorry if this is wrong but, I think the answer would be 48 inches.

Step-by-step explanation:

If every 3ft. = 2in. then I believe you would first divide the length and width by 3. So 6 divided by 3 is 2 and 18 divided by 3 is 6. Then you would multiply 2 and 6 by 2 since every 3ft = 2in.

Answers

Answer:

4,605cm

Step-by-step explanation:

You have to find the volume of the cone first (V=πr(2)h/

3). To do that you do 20/2 to get the radious, then you do (3.14)*(10^2)(24/3)=2512. Then you have to find the volume for the hemisphere (V=2/

3(3.14)r^3). Radious still equals 10, so 2/3*3.14*10^3= 2093. Add the two volumes together.

A pair of Adidas running shoes has a regular price of $65.00. The shoes are on sale for 20% off. The sales tax is 8%. What is the TOTAL cost of the shoes including tax?

Answers

The price should be $57.20
The total should be $56.16

First, find how much how much 20% off of 65 would be.

20/100 • 65 = 13

So you have to subtract 13 from 65
65-13=52

So with the 20% discount the price will be $52.

Next find out how much the sales tax will be.
52 • 8/100 = 4.16

The sales tax is 4.16. Add the sales tax with the price of the shoes.
52 + 4.16 = 56.16

Therefore, the total including the sales tax is $56.16.
