B is the proper answer. 200,000,000 is 2x10^8 and b is greater than that
so after the 10 non soloists join, there would be 60 students total and 12 of them are soloists.
12 is 20% of 60
Final Answer:
20% of the choir are soloists.
Hope this helped!
Have an awesome day :)
Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A = 
( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s² = 324 ( divide both sides by )
s² = 324 ( take the square root of both sides )
s = 
= 18
Thus
perimeter = 3 × 18 = 54 cm
Answer:
We can measure 4 gallon by successively.
Step-by-step explanation:
We have been given that you have an 8-gallon jug of water and two empty jugs with capacities of 5 gallons and 3 gallons, respectively. We are asked to prove or disprove that you can measure 4 gallon by successively pouring some of or all of the water in a jug into another jug.
First of all, we will pour 5 gallons of water from 8 gallon jug. Then we will pour 5 gallons of water from 5 gallon jug to 3 gallon jug. That will result in 2 gallons of water in 5 gallon jug.
Now, we will pour 3 gallons of water from 3 gallon jug to 8 gallon jug and pour 2 gallons from 5 gallon jug into 3 gallon jug. That will give us 6 gallons in 8 gallon jug and 2 gallons in 3 gallon jug and empty 5 gallon jug.
In our last step, we will fill 5 gallons jug from 8 gallon jug. After filling 5 gallon jug, we will fill 3 gallons jug from 5 gallon jug. Since 3 gallon jug already contains 2 gallons water, so it can only take one more gallon.
After pouring one gallon from 5 gallon jug, we will get 4 gallons water in 5 gallon jug.
Therefore, we can measure 4 gallon by successively pouring some of the water in a jug into another jug.
