Answer: Answer:
length= 53.22
width= 17.74
Step-by-step explanation:
Assuming the tank is a rectangular prism, then the formula for its volume will be:
volume= height* length * width
v= h * l * w
The length is equal to 3 times width, to put into the equation it will be:
l= 3w
We know that volume is 315 cubic feet and height is 3 feet, if you substitute all value into the equation we can find out the width.
v= h * l * w
315= 3 * l * w
945 = 3w * w
3w^2 = 945
w^2= 315
w= 17.74
Then we can find out length
l= 3 * w
l= 3* 17.74= 53.22

Answer:
If you shoot the bullet off the back of the car , the bullet will still be moving away from you and the gun at 1,000 mph, but now the speed of the train will subtract from the speed of the bullet. Relative to the ground, the bullet will not be moving at all, and it will drop straight to the ground.

Step-by-step explanation:
-7,-3,1,5,... is a arithmetic sequence.
Arithmetic sequences have a common difference. That is, it is going up by 4 each time.
When you see arithmetic sequence, you should think linear equation.
The point-slope form of a line is .
m is the common difference, the slope.
Any they are using the point at x=1 in the point slope form. So they are using (1,-7).
So let's put this into our point-slope form:
Subtract 7 on both sides:
So your answer is
