A rectangular prism has a surface area of 8 square feet. A similar rectangular prism has a surface area of 200 square feet. How many times larger are the dimensions of the larger prism?

5
10
25
625

Answers

The number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is 25 times.

Surface area of a rectangular prism

The surface area of a rectangular prism is as follows;

surface area = lwh

where

l = lengthw = widthh = height

Therefore,

surface area of the first prism = 8 ft²

surface area of the second prism = 200 ft²

Therefore, the number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is as follows;

200 / 8 = 25

Emily has 4 1/2 cups of chocolate chips. Her cookie recipe requires 3/4 cup of chocolate chips. How many batches of cookies can Emily make?

Answers

Answer:

There are 6 batches of chocolate chip cookies that can be made.

Step-by-step explanation:

First, turn 4 1/2 cups into an improper fraction with a denominator of 4 (which is 18/4). Then, do 18/4 divided by 3/4 (or 18/4 times 4/3 and both 4s cancel). The result is 18/3 or 6 because 3 times 6 equals 18.

The base sticker price is 90% of the price i.e.

The option price is 80% of included options i.e.

Convert 49° Celsius to degrees Fahrenheit using the following formula: F = {C+32 O A. 506.5°F OB. 196.2°F C. 94.6°F OD. 2237°F O E. 120.2°F​

Answers

Answer:

Step-by-step explanation:

F = 9/5C + 32

Putting value

9/5(49) + 32

88.2 + 32

= 120.2°F

Option E is the correct answer

The Celsius temperature 49 in Fahrenheit is 120 F.

To convert Celsius to Fahrenheit, you can use the formula:

F = (C × 9/5) + 32

Let's calculate the conversion using the given Celsius value:

C = Celsius temperature

F = (C × 9/5) + 32

F= (49 x 9/5)+ 32

F= 88.2 + 32

F = 120.2 F

Thus, Celsius temperature 49 in Fahrenheit is 120 F.

pedro's car averaged 957 miles on its 29-gallon tank of gas. If pedro runs out of gas and a mechanical comes to his rescue with 2 3/4 gallons of gas, determine how far his car can go. Round to the nearest​

Answers

Answer:

His car can go 90.75 miles.

Step-by-step explanation:

We solve this question using proportions.

Pedro's car averaged 957 miles on its 29-gallon tank of gas.

This means that per gallon, his car can go:

957/29 = 33 miles.

2 3/4 gallons of gas

[tex]2 + \frac{3}{4} = 2 + 0.75 = 2.75[/tex] gallons.

Determine how far his car can go.

For each gallon, the car goes 33 miles. He has 2.75 gallons, so his car can go 33*2.75 = 90.75.

His car can go 90.75 miles.
