You can calculate the velocity of each individual worker and model the velocity of both working together as the sum of the two individual velocity. Then you solve for the time.
Jack's velocity: 28 boxes / 2 h = 14 boxes / h
Walter's velocity: 36boxes / 3h = 12 boxes / h
Together velocity, V = 14 + 12 = 26 boxes / h
65 boxes => V = 65 boxes/t => t = 65 boxes / V
=65 boxes / 26boxes/h = 2.5 h
The equation that models the situation is V = 65/ t or t = 65/V
Answer:
<h3>2</h3>
Step-by-step explanation:
The value of pi is 22/7
Expressing as a decimal, the first ten digits of pi is 3.1415926535
The value in the tenth digit of the pi is 5 (tenth value after the decimal point)
The value of the ones is 3(The value before the decimal point)
The difference between both values = 5 - 3
The difference between both values = 2
Hence the difference of the ones and the tenth digit of the pi is 2
Answer:
1. 72
3. 79
Step-by-step explanation:
The mean is found by dividing the sum of the inputs by the total number of inputs.
He spent $36 on safety equipment.
The total cost each time was $11, meaning he had to pay 9 times for each skate session. 4x9=36! ( 7x9= 63 so if you add 36 you'll get 99 just as a way of checking)
