Answer:
98
Step-by-step explanation:
Of means multiply and is means equals
20% *x = 28
Changing to decimal form
.20 * x = 28
Divide each side by .20
.20x/.20 = 28/.20
x =140
Now we want to find 70% of 140
70% * 140
Changing to decimal form
.70 * 140
=98
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

Speed = 10 miles per hour.
Now, to get the distance from park to Billy's home we put formula:



Therefore, park is 5 miles from Billy's home.
Interest equals principle (the amount that you had to begin with) times the rate (the rate if interest) times the time (usually in years)
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
