Kira runs a total of 144 miles in 9 weeks.
Step-by-step explanation:
Given,
Distance covered on Monday = 2.5 miles
Distance covered on Wednesday = 5.75 miles
Distance covered on Friday = 7.75 miles
Total distance covered per week = 2.5+5.75+7.75 = 16 miles
Total distance in 9 weeks = Distance per week * 9
Total distance in 9 weeks = 16*9 = 144 miles
Kira runs a total of 144 miles in 9 weeks.

The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
3(4*3)=12*9
12*9=108
3(4*3)=3*4=12
3*3=9
12*9
Answer:
2.070552361 miles
Step-by-step explanation:
2 / cos 15 = 2.070552361
Answer:
25%
Step-by-step explanation:
The first doubling, from 20 to 40 occurs in a little more than 3 years, so the multiplier each year is a little less than 2^(1/3) ≈ 1.26. That is, each year is a little less than 26% more than the previous year.
The graph also goes near the point (8, 120), so grows by a factor of 6 in 8 years. That suggests a multiplier of 6^(1/8) ≈ 1.251. Each year is about 25.1% more than the previous year.
Both of these multipliers represent yearly growth rates near 25%.
___
Using the "rule of 72", the product of doubling time and percentage growth is about 72. So, for a doubling time of 3 years, the percentage growth is predicted to be near 72/3 = 24 percent.
All of these estimates help you choose the correct answer: 25%.
