You would do 28 divided by 1/48, which is 1344. Therefore, the actual plane is 1,344 in long

rachel is frosting the top of two cakes and wants to know which cake will require more frosting. one cake is round with a diamet

Jet001 [13]

Answer:

The square cake is has a larger area by about 40.73 square inches

Step-by-step explanation:

Find the area of the top of each cake.

The square cake has an area of 81 sq inches, ( length x width = Area, the

length is 9)

The round cake has an area of 16π, which is about 50.27 square inches

(A = πr², here r is 4, radius is half the diameter)

81 - 16π = 81 - 50.27 = 40.73 square inches

The surface areas of two similar solids are 340 yd² and 1,158 yd². The volume of the larger solid is 1,712 yd³. What is the volu

ratelena [41]

The ratio of surface area is equal to the ratio of the square of the corresponding dimensions. And ratio of volumes of two solids is equal to the cube of the ratio of the corresponding dimensions .

We start with the relation between ratio of surface area and ratio of corresponding sides. That is

$\frac{340}{1158}=(\frac{x}{y} )^2$

Here x and y are the corresponding sides .

$\frac{x}{y} =\sqrt{\frac{340}{1158} } =0.542$

Let the volume of the smaller one be v

$\frac{v}{1712}=0.542^3$

$v=1712*0.542^3=272$

So for the smaller solid, volume is 272 . And the correct option is the first option .

Shaniqua is saving money to buy a new television that costs $252. She already has $87 saved. If she gets paid $11 per hour,how m

suter [353]

Answer: 15 hours

Step-by-step explanation:

Total cost of TV = $252, Savings= $87. So, she will require, $252-$87 = $165 to buy TV.

Also, it's given that, she gets paid $11 per hour.

Therefore, she will require 165/11 hours = 15 hours to buy new Tv at the wage rate of $11/ hour.
