Answer:

1/36

Step-by-step explanation:

When you put something to a negative exponent, you are essentially putting it over 1. So 6^-2 would become 1/6^2. Solving 6^2 gives you 36, so the full equation would be 1/36.

Rearrange the equation algebraically to solve for the unknown quantity.

timofeeve [1]

Given:

Consider the given equation is

$P=2L+2W$

To find:

The solution of the equation for l.

Solution:

We have,

$P=2L+2W$

Substract 2W from both sides.

$P-2W=2L+2W-2W$

$P-2W=2L$

Divide both sides by 2.

$\dfrac{P-2W}{2}=\dfrac{2L}{2}$

$\dfrac{P-2W}{2}=L$

$L=\dfrac{P-2W}{2}$

Therefore, the correct option is 3.

Find the distance between the coordinates (0, 4) and (10,4) and write the result in the empty box.

barxatty [35]

The distance between the coordinates (0, 4) and (10,4) is 10

Step-by-step explanation:

We need to find the distance between the coordinates (0, 4) and (10,4)

The formula used to find distance is:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

where

$x_1=0, y_1=4, x_2=10,y_2=4$

Putting values:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(10-0)^2+(4-4)^2}\\Distance=\sqrt{(10)^2+(0)^2}\\Distance=\sqrt{(10)^2}\\Distance=10$

So, The distance between the coordinates (0, 4) and (10,4) is 10

If the surface area of a sphere is 530.93 square cntimeters, find the volume of the sphere

hodyreva [135]

The volume of sphere is: 1149.76\ cm^3

Further explanation:

We have to find the radius of the sphere first to find the volume of sphere

Given

Surface Area of Sphere=530.93 cm^2

$SA=4\pi r^2\\530.93=4*3.14*r^2\\530.93=12.568r^2\\r^2=\frac{530.93}{12.56}\\r^2=42.27\\Taking\ Square\ root\ on\ both\ sides\\\sqrt{r^2}=\sqrt{42.27}\\r=6.5\ cm\\Now,\\V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}*3.14*(6.5)^3\\=\frac{4}{3}*3.14*274.625\\=1149.76\ cm^3$

The volume of sphere is: 1149.76\ cm^3
