1) Temperature in Fahrenheit =77°F.

2) Temperature in Celsius= 25°C

3) Height of rectangular prism = 8 inches

4) Width of rectangle = 40 inches

Step-by-step explanation:

1) If Temperature is 25°C . How many degrees Fahrenheit is it?

The formula to calculate temperature in Fahrenheit is:

F=(C\times\frac{9}{5})+32

Putting value of Celsius:

F=(C\times\frac{9}{5})+32 \\F=(25\times\frac{9}{5})+32\\F=(5\times9)+32\\F=45+32\\F=77

So, 25°C in Fahrenheit is 77°F.

2) If temperature is 77°F,what is the temperature in Celsius?

The formula used is:

C=(F-32)\times\frac{5}{9}

Putting value of Fahrenheit is:

C=(F-32)\times\frac{5}{9}\\C=(77-32)\times\frac{5}{9}\\C=45\times\frac{5}{9}\\C=25

So, temperature in Celsius is 25°C.

3) The volume of triangular prism is 64 inches³. The length is 2 inches and width is 4 inches. What is height.

The formula of finding volume of triangular prism is:

V=L\times W\times H

Putting values:

V=L\times W\times H\\64=2\times 4\times H\\64=8\times H\\H= 64/8\\H=8

So, height of triangular prism is 8 inches.

4) The area of rectangle is 80 inches. if length is 20 inches what is the width of rectangle.

The formula used is:

Area=Length\times Width

Putting values:

Area=Length\times Width\\80=20\times Width\\W=80/20\\W=40

So, width of rectangle is 40 inches.

Debora [2.8K]

Answer:

#a. $80

#b. $1680

Step-by-step explanation:

We are given;

  • Amount invested (principal) is $1600
  • Rate of interest is 5%
  • Time = 1 year

We are required to determine the amount of simple interest earned and the amount or balance in the account after 1 year.

#a. Interest earned

To calculate simple interest we use the formula;

I = (PRT) ÷ 100

Where, P is the principal, R is the rate, T is the time and I is the simple interest.

Therefore;

I = (1600 × 5 × 1) ÷ 100

 = $80

Therefore, simple interest earned is $80

#b. Balance of the account (Amount accrued)

We are going to use the formula;

A = P + I , where A is the amount accrued, P is the principal and I is the simple interest earned.

Therefore;

Account balance = $1600 + $80

                            = $1680

Thus, the account balance after 1 year will be $1680
