The missing side of the triangle if the perimeter is equals to 81 is 28.8

<h3>Perimeter:</h3>

Perimeter is the sum of the whole sides of a figure. The perimeter of the triangle above is the sum of the whole three sides.

Therefore,

let

the missing side = x

perimeter = 81

27.7 + 24.5 + x = 81

52.2 + x = 81

subtract 52.2 from both sides

52.2 - 52.2 + x = 81 - 52.2

x = 28.8

pshichka [43]

Using the percentage concept, it is found that 95.4% of the park will be used for other activities.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

P = \frac{a}{b} \times 100\%

In this problem, there will be two courts of 5,000 square feet each, totaling 10,000 square feet. The remainder 207,800 square feet will be used for other activities, hence the percentage is given by:

P = \frac{207,800}{217,800} \times 100\% = 95.4\%

95.4% of the park will be used for other activities.

If the Ramirez family deposits $5000 in a savings account at 7.5% interest compounded continuously, how much will be in the acco
GenaCL600 [577]

Answer: The amount is $14794.39 and the interest is $9794.39

Step-by-step explanation: If you deposit <em><u>$5000</u></em><u> </u>into an account paying <em><u>7.5%</u></em> annual interest compounded yearly , how much money will be in the account after <em><u>15 years</u></em>?

To find amount we use formula:

A-P(1+r/n) n*t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

P=$5000, r=7.5, n=1 and, t=15 years

After plugging the given information we have

A= $5000 (1+0.075/1)^1.15

A= 5000 *1.075^15

A=14794.39

To find interest we use formula  A=P+I'

since A= 14794.39  and P=5000

we have: A=P+I 14794.39=5000+I

I= 14794.39 -5000

I=9794.39
