Sarah is 14
The twins are 12
The youngest (n) is 7
14+(12+12)+7=45
n=7
An equation that would represent the relationship between cost and revenue would be: 7.50t + 15s = 525
Hope this helps!! :)
Answer:
51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
Step-by-step explanation:
Given:
75 feet/second.
Now, to convert 75 feet/second into miles/hour.
So, to convert we divide the value of feet per second by conversion factor to get miles per hour.
Value of feet per second = 75.
Conversion factor = 1.4667.
Now, putting the formula to get the value in miles/hour:
Value in miles/hour = value of feet/second ÷ conversion factor.
Value in miles/hour = 
= 
<em>Rounding nearest to whole number = 51 miles/hour.</em>
Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3
