This is the equation you need to use: y = kx
So, let's put it this way:
y can be the total amount of money you spend (so $48), and x the number of people (6)

y=kx
48=k*6
k = 48/6
k = 8

The constant variation, and the price of one ticket is 8.

The diameter of a cookie is 2 inches. If π = 3.14, what is the area of the cookie, rounded to the nearest tenth?

insens350 [35]

Answer:

3.1 inches

Step-by-step explanation:

Area of the cookie =Pi r^2

Pi = 3.14

Diameter = 2inches

Radius r = diameter/2 = 2/2

= 1

Therefore

Area = 3.14 x 1^2

= 3.14 x 1 x 1

= 3.1 inches

a home building contractor bought 4 2/8 acres for $165,000. What was the cost of each acre? (round to nearest dollar.)

pychu [463]

Answer: $38,824

Step-by-step explanation:

Convert the mixed number $4\ \frac{2}{8}$ as a decimal number.

Divide the numerator by the denominator and add it to the whole number 4. Then:

$4+0.25=4.25acres$

Then, knowing that 4.25 acres cost $165,000 , divide this amount by 4.25 acres to find the cost of each acre.

Therefore, you get that the cost of each acre rounded to nearest dollar is:

$cost=\frac{\$165,000}{4.25}\\cost=\$38,824$
