Consider the expression √(√625).

const2013 [10]

Answer:

Step-by-step explanation:

Square Root - Finding a number that multiplies itself twice into the number within the square root

With this meaning, we need to find a number that multiplies itself into 625.

Finding calculations using exponents will help,

25^2 is equal to 625. Therefore $\sqrt{25}$

We are not finished, as there is another square root right after, empowering the parenthesis, so what number multiplies itself equals 25?

This would be 5, therefore $\sqrt{(\sqrt{625}) }$ is equal to 5.

Kimiya has four times as many marbles as Ramneet. If kimiya gave 18 to Ramneet they would have the same number. How many marbles

RSB [31]

Answer:

Kimiya has 48 marbles, Ramneet has 12 marbles

Step-by-step explanation:

kimiya has 4x marbles ramneet has x marbles then 4x - 18 = x + 18 because if you give 18 marbles from kimiya to ramneet then you subtract 18 from kimiya and add 18 to ramneet by solving the equation you will get x as 12.So kimiya has 48 marbles, ramneet has 12 marbles.

Find the volume of this sphere.<br> Use 3 for T.<br> V~ [?]in3<br> V = Tr3<br> r=4in

timofeeve [1]

Answer:

The answer is 256 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = $\frac{4}{3} \pi r^{3}$ . However, in this formula, 3 will be used instead of ( $\pi$ ).

Next, plug in the information given from the problem, and the formula will look like V = $\frac{4}{3}$ (3) ( $4 in^{3}$ ).

Then, solve the equation, and the answer will be 256 $in^{3}$ .
