6(3x+5)
6*3x=18x
6*5=30
<u>18x+30</u> is your answer! I hope this helped! :)
In order from left to right:
D, C, A, B
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
Answer:
A beach ball is a sphere, so we will need to know how to find the volume of a
sphere. V = 4Pi * (r ^ 3 / 3)
We have the diameter, but not the radius. To find the radius, it is half of the
diameter.
10÷2=5 Now let's plug it in.
4T(5³/3) Let's solve.
4pi = 12.56
5³= 125
125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752
523.33 cubic inches is the volume of
air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for
we rounded up to 41.67, when there was
the answer to be a couple decimals lower
from the answer we got. Tell me if this helps!!
