I got 11.28. By subtracting 9.72 by 21 to get x alone
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:
5.264 * 10^4
Step-by-step explanation:
We put a decimal point to the right of the number, so
52640.
Then we move it to the left until we get a number that is between 1 and 10.
5.2640
This was four hops to the left.
We can remove the trailing 0, and write
5.264 * 10^4
10^4 because of the four hops
This is a lot of math to write.... so I'll just say the answer is -21 :D
Answer:
(0, 6), (2, 7)
y = mx + b
m = (7 - 6)/(2 - 0) = 1/2 = 0.5
b = 6
y = 1/2*x + 6
1/2*x - y = -6
So, answer D is correct. But m is the fraction 1/2 and not 12.
