19. The ratio of cars to trucks in a parking lot is 8 to 5 trucks. There are 25 trucks in the parking lot. How many total cars and trucks are in the parking lot?

Below in bold.

Step-by-step explanation:

The ratio is 8 : 5

So there are 8/5 = 1.6 more cars than trucks.

So the number of cars in the lot = 25 * 1.6 = 40

So the total of vehicles in the parking lot = 25 + 40 = 65.

the graph top, left is y = 4x

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
