He would earn $10 in 4 hours

You would have to divide $22.5 by how many hours he worked so it would be 9 hours. Once u divide, that’s how much he earns hourly. So your next step is to multiply what he earns hourly ($2.5) by 4 hours because they’re only asking how much he earned for 4 hours.

What is the slope of the line through (−1,−7) and (3,9)?

Alona [7]

Answer:

The slope is 4.

Step-by-step explanation:

Point slope form is y-y1 over x-x1. I put the coordinates in like this.

9-(-7) over 3-(-1) so thats 9+7 over 3+1. 16 over 4 is 4.

Pedro bought a skateboard last week. The list price of the skateboard was $64.90. He has a 20% coupon. He has to pay 8.5%

Lapatulllka [165]

Take the original price and times it by .8 (you could times it by .2 and then subtract from the original price but multiplying it by .8 is much easier) 64.9x.8= 51.92 take your discounted price and multiply it by 1.085 to account for the sales tax (you multiply by 1.085 to account for the price of the item and the tax you could times it by .085 and then add it on to the price of the item but this way it shortens the amount of steps needed) 51.92x1.085= 56.3332
Round to the nearest cent
Answer=$56.33

30 FREE pts Which equation could have been used to create this function table? A. y = 5x B. y = x + 1 C. y = x + 2 D. y = 2x

Crank

The answer is choice D.

y = 2x

I will show two reasons why this equation is correct.

Let x = 1

y = 2(1)

y = 2

The first point in the table is (1,2).

In the table, x = 3 is the second choice.

y = 2(3)

y = 6

The second point in the table is (3,6).

Answer: y = 2x

First, Khianna must walk from the front gate to the Ferris wheel. This distance is 2.5 cm on Khianna's map. How far is the actua

spin [16.1K]

Okie doke. 1cm on the map equals 500 meters. The distance from the gate to the ferris wheel on the map is 2.5cm. To find the actual distance, multiply the length on the map by the distance per centimeter. 500 * 2.5 is 1,250. The actual distance is 1,250 meters.

Note: When it comes to problems like these, you must always multiply the distance on the map by the scale unit (in other words, the actual distance on how far it is per the smaller unit).
