If y=15 then x=45 because 45 minus 15 is 30

Hope this helps :))

A rectangular prism has dimensions of 2 ft, 4 ft, and 6 ft. If the dimensions are doubled, what would happen to the volume?
kondor19780726 [428]

Answer:

Volume is increased in a factor of 8. The volume is increased from 48\,ft^{3} to 384\,ft^{3}.

Step-by-step explanation:

The formula for the volume of the rectangular prism is:

V = w\cdot h \cdot l

Where:

w - Width

h - Height

l - Length

If dimensions are doubled, then volume is increased in a factor of 8:

V_{f} = (2\cdot w)\cdot (2\cdot h)\cdot (2\cdot l)

V_{f} = 8\cdot w \cdot h \cdot l

V_{f} = 8 \cdot V_{o}

The volume is increased from 48\,ft^{3} to 384\,ft^{3}.

Is the equation x9 - 5x3 + 6 = 0 quadratic in form? explain why or why not.
Varvara68 [4.7K]

Answer:

Yes.

Step-by-step explanation:

Yes, because we can replace x^3 by another variable, say y:

x^9 - 5x^3 + 6 = 0  

Let x^3 = y, then  we have x^9 = (x^3)^2 = y^2:

y^2 - 5y + 6 = 0  which is quadratic from.

Philip can run a mile in 6 minutes. What is his speed in miles per hour?<br><br> I need help
3241004551 [841]

Answer:

10 MPH

Step-by-step explanation:

Well since there is 60 minutes in an hour, you can easily take 6 and multiply it by 10 since that will equal 60. 1 mile takes 6 minutes and because we multiplied the amount by 10, we can multiply the amount of miles by 10 as well. If Philip runs at a constant rate for 60 minutes straight, he will be going at 10 MPH. Hope this helps!
