What percent of 300 is 51

Gnoma [55]

Answer:

Step-by-step explanation:

300:51*100 =

(300*100):51 =

30000:51 = 588.24

Now we have: 300 is what percent of 51 = 588.24

Question: 300 is what percent of 51?

Percentage solution with steps:

Step 1: We make the assumption that 51 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=51$100%=51.

Step 4: In the same vein, $x\%=300$x%=300.

Step 5: This gives us a pair of simple equations:

$100\%=51(1)$100%=51(1).

$x\%=300(2)$x%=300(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{51}{300}$

100%

x%=

300

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{300}{51}$

100%=

300

$\Rightarrow x=588.24\%$⇒x=588.24%

Therefore, 17% of 300 is 51

A sphere has a diameter of 0.926 inch.

frosja888 [35]

Answer:

The volume of the sphere is $V=0.416 \:in^3$ .

Step-by-step explanation:

The volume enclosed by a sphere is given by the formula

$V=\frac{4}{3}\pi r^3$

Where r is the radius of the sphere.

The diameter of a sphere is twice as long as any radius of the same sphere and is given by the formula

$d=2r$

We know that the diameter of the sphere is 0.926 inch. The radius is

$\frac{0.926}{2}=0.463$

The volume of the sphere is

$V=\frac{4}{3}(3.14)(0.463)^3 \approx0.4155385$

and rounding to the nearest thousandth we get $V=0.416 \:in^3$ .
