In which of the following situations would finding the surface area of an object be the most applicable?

Answers

Hi, you've asked an incomplete question. However, I provided a brief explanation about surface areas.

Explanation:

Surface area is a term commonly used in mathematics, and other branches of science, and it basically refers to a calculation of the total space that an object occupies.

For example, you can find the surface areas of a cuboid using the formula:

[tex]6s^{2}[/tex] where s= side length.

Monica deposits $300 into a savings account that pays a simple interest rate of 4.2% paul deposits $400 into a savings account that pays a simple interest rate of 3.8% monica says that she will earn more interest in 1 year because her interest rate is higher is she correct?

Answers

Answer:

Paul earned $2.6 more interest than Monica.

Step-by-step explanation:

Giving the following information:

Monica:

Initial investment= $300

Interest rate= 4.2%

Paul:

Initial investment= $400

Interest rate= 3.8%

To calculate the income earned, we need to use the following formula:

I= P*r*t

P= principal

r= interest rate

t= time

Monica:

I= 300*0.042*1= $12.6

Paul:

I= 400*0.038*1= $15.2

Paul earned $2.6 more interest than Monica.

Using the variable n for the term, describe the sequence.

Answers

Answer:

3 + 5n

Step-by-step explanation:

This is an arithmetic sequence.

First term = a = 8

Common difference = d =Second term - first term

                                = 13 - 8

                                 = 5

Nth term = a + (n- 1)*d

              = 8 + (n -1) * 5

             = 8 + n*5 - 1 *5

              = 8 + 5n - 5

               = 8 - 5 + 5n

                = 3 + 5n

Angela is 4 feet 7 inches tall. Angela's doll is 11 inches tall. What is the ratio of Angela's height to the
doll's height?

Answers

Answer: 5:1 (simplified and in inches)

Step-by-step explanation:

Let’s convert Angelicas height in inches so all the measurements are the same.

Anglelicas height: 4 ft7 in

OR

Angelicas height: 55 inches

Dolls height: 11 inches

The ratio would be 55:11 but we would need to simplify since both numbers are divisible by a GCD (greatest common denominator)

55 and 11 are both divisible by 11 so the new simplified ratio would be...
