Answer:
<u>Consider the following identity:</u>
- a³ - b³ = (a + b)(a² - ab + b²)
<u>Let a = 2, b = 1/2</u>
- (2 + 1/2)(2² - 2*1/2 + 1/2²) =
- 2³ - (1/2)³ =
- 8 - 1/8

A. 13 classes completed worth 3 credits.
Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains
Number of cars in each train =
= 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car
Number of cars = 16
14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224
10 = <em>2240</em>
Answer:
9 minutes
Step-by-step explanation:
First, you will want to add up all the time spent per problem.
3(9.5)+2(8.25)=45
Then, divide 9 from 45. 45÷5=9.
Therefore, she would have spent 9 minutes per problem.
