b) If the family decides to send their child to a 4-year public college, they will spend \$7500 per year

c) Valnez family will be pay \$12517 per year to raise the child from birth to 18 years old

d) \$15714 is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college

Step-by-step explanation:

Part a) How much will the Smith family spend per year to raise their child from 5 to 18 years old? Round to the nearest dollar.

The cost from 5 to 18 years old is $145,700

Per year cost will be:

Divide the total amount by the number of years from 5 to 18 years. i.e 18-5 = 13 years

Cost per year: \frac{145700}{13}

Cost per year:\$11208

So, Smith family spend  \$11208 per year to raise their child from 5 to 18 years old.

Part b) If the family decides to send their child to a 4-year public college, how much will they spend per year?

The cost of 4 year Public College $30,000

Cost per year: \frac{30000}{4}

Cost per year: \$7500

So, If the family decides to send their child to a 4-year public college, they will spend \$7500 per year

Part c) How much will the Valnez family pay per year to raise the child from birth to 18 years old

Cost from Birth to 5 years old $79,600

Cost from 5 to 18 years old $145,700

Total\,\,cost = \$79,600+\$145,700\\Total\,\,cost =\$225300

Total years: 18

Cost per year: \frac{225300}{18}

Cost per year: \$12517

Valnez family will be pay \$12517 per year to raise the child from birth to 18 years old

Part d) What is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college? Round to the nearest dollar.

From birth to 18 years (found in part c)

Cost from birth to 18 years: $225300

Cost of 4-year Private College: $120,400

Total Cost: \$225300+\$120,400

Total Cost: \$345700

Total years: 18+4 = 22

Cost per year: \frac{345700}{22}

Cost per year: \$15714

\$15714 is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college

Find the perimeter and area of the figure.
Brums [2.3K]

Answer:

P = 12m

A = 6m^2

Step-by-step explanation:

Perimeter is the sum of all the lengths of a shape. The lengths of the triangle are given as 3m, 4m, and 5m, so to find the perimeter we just need to add them all together. 3+4+5=12, so the perimeter of the triangle is 12m.

The area of a triangle is found by multiplying its height by its base and then dividing the result by 2. The height of the triangle is not given, but the side lengths (3,4 and 5) indicate that the triangle is a right triangle. This means we can use the middle length as the height and the shortest length as the base.

So, the height of the triangle is 4m, and the base is 3m, so to calculate the area:

(3x4)/2=12/2=6m^2.

The area of the triangle is 6m^2.

Hope this helped!
