Answer:

145,7

Step-by-step explanation:

The area of the circle is 2πr

The area of the rectangle is b·h

Applied to this figure is:

2·π·r = 2·3,14·5 = 31,4 this is a semicircle so you have to divide by 2. 31,4/2 = 15,7

b·h = 13·10 = 130 (you can know the high because the double of the radio is the diameter)

130 + 15,7 = 145,7

Answer:

3,750 cars.

Step-by-step explanation:

We are given that the equation:

$y=9000-2.4x$

Models the relationsip between y, the number of unfilled seats in the stadium, and x, the number of cars in the parking lot.

We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.

When there are no unfilled seats in the stadium, y = 0. Thus:

$0=9000-2.4x$

Solve for x. Subtract 9000 from both sides:

$-2.4x=-9000$

Divide both sides by -2.4:

$x=3750$

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.

Write an equation that relates the number of peppers, n, and the cost, C.

SCORPION-xisa [38]

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the cost, C.

Answer:

$C = 0.45n$

Step-by-step explanation:

Given

$5\ peppers = \$2.25$

Required

Determine the relationship between C and n

$5\ peppers = \$2.25$

Divide both sides by 5, to get the cost of 1 pepper

$\frac{5\ peppers}{5} = \frac{\$2.25}{5}$

$1\ pepper = \frac{\$2.25}{5}$

$1\ pepper = \$0.45$

Multiply both sides by n to get the cost of n pepper

$n*1\ pepper = \$0.45*n$

$n\ pepper = \$0.45n$

So, we have:

$C = 0.45n$
