1000. You need to divide 1500 by 30 to get 50. Then you multiply that by 20. Please mark as brainliest!
Answer:
The answer is the fourth one 375/1000.
Answer:
Here we want to calculate the 25% of $140.
Well, first we assume that:
$140 = 100%.
Now, assuming that, we can write the equation:
X = 25%
Where X is the 25% of $140.
Then we have the equations:
$140 = 100%
X = 25%
Let's take the quotient between these equations:
$140/X = (100%/25%)
Now let's solve this for X:
X = (25%/100%)*$140 = 0.25*$140 = $35
Then the tip will be of $35
Answer:
r = 3m
Step-by-step explanation:
Formula for the volume of a sphere: V = 


We want to find the radius so we use algebra to rearrange the equation to make the radius (r) the subject of the equation
Divide both sides by 
= 

Divide both sides by 
= 
Take the cube root of both sides
= r
Substitute V = 36
into the equation
r = ![\sqrt[3]{\frac{3(36\pi) }{4\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3%2836%5Cpi%29%20%7D%7B4%5Cpi%20%7D%20%7D)
Expand the bracket
r = ![\sqrt[3]{\frac{108\pi }{4\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B108%5Cpi%20%7D%7B4%5Cpi%20%7D%20%7D)
Divide 108
by 4
(For this, the two
in the numerator and denominator cancel each other out, and you only need to divide 108/4)
r = ![\sqrt[3]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D)
The cube root of 27 is 3, because
= 3 x 3 x 3 = 27
r = 3
