bezimeni [28]

Answer:

Step-by-step explanation:

From the question, we are informed that investors buy a studio apartment for $180,000 and that they have a down payment of $36,000. The percentage of the down payment on the purchase price will be:

= 36000/180000 × 100

= 1/5 × 100

= 20%

What percent of the purchase price would a ​$9,000 down payment​ be?

This will be:

= (9000 / 180000) × 100

= 0.05 × 100

= 5%

A cyclist rides his bike at 12 miles per hour. What is this speed per minute? How many miles will the cyclist travel in 20 minut
grandymaker [24]

Answer:

In order to find the distance traveled in one minute, you have to divide the distance he can ride his bike in an hour by the number of minutes in a hour. 6/60= .1 mile per minute. If he rides his bike for five minutes, then you would multiply the number of minutes biked by the distance traveled in a minute. .1*5=.5 mile, or \frac{1}{2} mile.
