The cost of painting the circular traffic sign shown below is $3.50 per square foot. how much to the nearest dollar, will it cost to paint the sign if its diameter measures 36 inches?

Use conversion:

1 square foot = 144 square inches.

As per the statement:

The cost of painting a circular traffic sign is $3.50 per square foot.

⇒Cost of painting a traffic sign = $0.025 square inches.

It is also given that: Diameter measures 36 inches.

Area of a circle is given by:

where r is the radius of the circle.

Diameter = 2r

⇒

Divide both sides by 2 we get;

then;

square inches.

1 square inches  = $0.025

then;

In 1,017.36 square inches =

Therefore, $25 ( to the nearest dollar) will it cost to paint the sign if its diameter measure 36 inches.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
