5 0

Answer:

8 44/45

Step-by-step explanation:

Find the LCM of 9 and 5, which is 45.

Then, set 7/9 with a denominator as 45, so it's 35/45.

Do the same for 1/5, so it's 9/45.

Add 3 + 5 + 35/45 + 9/45 to get 8 44/45.

kolezko [41]

Answer:

A motor running at 75 revolutions per second.

Step-by-step explanation:

Given statement: A motor running at 4500 RPM, revolutions per minute.

⇒ In one minute , a motor running at 4500 revolutions.

Use conversion:

1 min = 60 sec

We have to calculate how many revolutions per second.

in 60 sec , a motor running at 4500 revolutions

then,

in 1 sec , a motor running at \frac{4500}{60} = 75 revolutions.

Therefore, a motor running at 75 RPS, revolution per second.

Justin buys a racehorse for $25,000 and enters it in two races. He plans to sell the horse afterwards, hoping to make a profit.
GenaCL600 [577]
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000

b) Wins first only:
Chances are: 25% x 65% = 16.25%

c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%

d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
