A car is traveling at 48 miles per hour. What is the speed of the car in centimeters per second? (1 mile = 5,280 feet, 1 foot = 12 inches, 1 centimeter = 0.39 inch)
Solution:
We have 48
To convert, miles to centimeters.
Let us convert miles to feet and then inches and then centimeters.
1miles=5280feet
And, 1 foot=12inches
So, 5280 feet or 1 miles =12*5280inches
So, 1miles=63360inches
Now, Let us convert inches to centimeters
1centimeter=0.39inches
Or, 1 inch= centimeter
So, 63360inches (or 1 mile)= centimeter
1mile or 63360inches=162461.54centimeter
1mile=162461.54 centimeter
We have, 48
We have, 48 *
We have, 48*
So, We have, 48*
=48*
=48*45.13
=2166.15
Answer:= Speed of the car in centimeters per second is 2166.15 centimeters/second
Given that,
A food truck is selling 2 burritos for $5.
Solution,
We need to find the relationship between burritos and dollars.
2 burritos = $5
To find the value of 1 burrito. Divide 5 by 2 as follows :
Hence, the relation between burritos and dollars is " "
Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of ().
Since we must sum the first <em>three </em>geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.
Knowing this you can plug in the corresponding i values into () and sum it all together
