The volume flow rate of the air being pumped into the football will be given by:
Q=V*A
Where
V=Speed
A=Area
You know that your pump expels air at speed of 8.2 ft/s
The area of The needle of your pump is
A=pi*r^2=pi*((4.5/1000)*(3.28))^2=0.00068442 ft^2
Finally
Q=V*A=(8.2 ft/s)*(0.00068442ft^2)=0.005612243 ft^3/s
Answer:
25
Step-by-step explanation:
The like terms are the a terms and the constants. If you combine them, you will get 24, as the negative a and the positive a cancel each other out.
130-54=76
You just need to know when there is +- you just subtract the numbers with the charge of the largest number
