Emily bikes 12 miles, generating a donation unit for every 0.75 miles. Her 12 mile ride will generate
12 × 0.75 = 9 donation units. For each of these 9 danation units her mother will donate 80 cents.

It follows that Emily's mom will donate
9 donation units × $0.80 per unit = $7.20.

Billy left home at 9 a.M. And rode his bicycle to the park at an average speed of 10 miles per hour here I got the park at 9:30
tamaranim1 [39]

Answer:

Park is <u>5 miles</u> from Billy's home.

Step-by-step explanation:

Given:

Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.

Now, to find the distance from park to Billy,s home.

Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.

So, the time = (9.30 - 9.00) = 30 minutes

=\frac{30}{60}  =0.5\ hour.

Speed = 10 miles per hour.

Now, to get the distance from park to Billy's home we put formula:

Distance=Speed\times Time.

Distance=10\times 0.5

Distance=5\ miles.

Therefore, park is 5 miles from Billy's home.

Simplify the expression and show work.
nasty-shy [4]

Answer:

72/149

Step-by-step explanation:

Just to clarify, the curly braces mean the same thing as normal parenthesis.

(12 + 5^2) = (12 + 25) = 37

(-7-15)^2 = (-22)^2 = 484

6^3  = 216

(12 + 5^2) - (-7-15)^2 = 37 - 484 = 447

6^3 / ((12 + 5^2) - (-7 - 15)^2) = 216 / 447 = 72/149
