Answer:

6x^2√x

Step-by-step explanation:

6 times 6 is 36

So you can take 6 out and leave x^5

However x^5 also have a power to square by:

x^4 which can turn into x^2

So we can take x^2 out

So the answer is 6x^2√x

Hope this helps!

Can someone help me with these two questions?The last answer choice is 90 degrees.

gizmo_the_mogwai [7]

For the first one:

The radian of 60º is 1.047. you just have to find one that has the same value, which would be $\pi$ /3. (the last choice).

for the second one:

you do it the other way. The answer is 45 degrees.

The prism is completely filled with 1750 cubes that have edge length of 15 ft.

neonofarm [45]

The volume of the prism = 14 ft³

Solution:

Number of cubes in the prism = 1750

Edge length of each cube (a) = $\frac{1}{5}$ ft

<u>To find the volume of each cube:</u>

Volume of each cube = a³

$$=\left(\frac{1}{5} \right)^3$

Volume of each cube $$=\frac{1}{125} \ \text{ft}^3$

<u>To find the volume of the prism:</u>

Volume of the prism = Volume of each cube × Number of cubes

$$=\frac{1}{125} \ \text{ft}^3\times 1750$

= 14 ft³

The volume of the prism = 14 ft³

Suppose a jar contains 13 red marbles and 11 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same

Alisiya [41]

I’d say around 75% or less

This is just an assumption considering that there are more red than blue but only trumps blue by 2. Taking out those two, you’d be left with a 50% chance of getting red and/or blue marbles
