It takes 15 minutes for Ms. Peter to drive from park to her home
Given :
from her home to the park at an average speed of 30 miles per hour and
returned home along the same route at an average speed of 40 miles per hour
it takes 20 minutes to travel
Convert 20 minutes in to hour (divide by 60)
20 minutes = 1/3 hour
We know that distance = speed x time
From home to park, distance =
So , distance between home and park is 10 miles
Now we calculate the time taken to return from park to home
Time taken is 1/4 hours. Convert it into minutes by multiplying by 60
So it takes 15 minutes for Ms. Peter to drive from park to her home

Answer:
21
Solution:
90 degrees + 15 degrees = 105 degrees. This angle is complementary to 5x. Therefore 105=5x. Solving for x we get 21

Answer:
Step-by-step explanation:
It's a matter of being consistent in a pattern:
Let a be a number. If a^(-3) is the first number, it's equal to 1 / a^3.
Next:
1 / a^2
1 / a^1
?? To fit into this pattern, a^0 must equal 1.
a^1
a^2
a^3
and so on.
Try this same exercise with a = 2:
2^(-2) = 1/4
2^(-1) = 1/2
?? This number has to be 1 to fit the pattern. 2^0 = 1. Note that each
term is 2x the previous term: 2(1/4) = 1/2; 2(1/2) = 1; 2(1) = 2; 2(2) = 4,
and so on. Again, 2^0 must = 1 to fit into this sequence.
2^1 = 2
2^2 = 4
For the 1st one it is:
85% of 1600 is 1,360
For the 2nd one it is:
816 of 850 is %96
