Answer:
Part 1) The new distance from the water to the top of the tank is
Part 2) The maximum number of balls that can be put into the tank with the tank not overflowing is 95
Step-by-step explanation:
step 1
Find the total volume of the tank
step 2
Find the volume of the tank if the water level is two inches below the top of the tank
step 3
Find the volume of the glass sphere
The volume of the glass sphere is equal to
we have
assume
substitute
step 4
What is the new distance from the water to the top of the tank?
we know that
so
using proportion
Find how many inches correspond a volume of
The new distance from the water to the top of the tank is
step 5
Find how many of these balls can be put into the tank with the tank not overflowing
we know that
The volume of one ball is equal to
using proportion
therefore
The maximum number of balls that can be put into the tank with the tank not overflowing is 95
Answer:
40%
Step-by-step explanation:
If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.
I like to do cross multiply and divide so the equation for that would be 480/120 = ?/100
if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.
Im basically just saying 480/1200 = 40%
If you need further help there are plenty of you tube videos on how to cross multiply and divide
Hope this helps

Answer:
56
Step-by-step explanation:
First, convert the 70% so that we can use it with the 80 cups. To do this, convert the percent to a decimal by moving the decimal 2 spaces to the left:
70% → 70.00 → 0.70 → 0.7
70% percent can be seen as 0.7. Multiply this by 80:
So, 70% of 80 is 56. Desmond sold 56 cups on the second Saturday.
