Answer:
B. 12.5%
Step-by-step explanation:
Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:
100%=20(1)
x%=2.5(2)
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
[tex]\frac{100}{x}[/tex]=[tex]\frac{20}{2.5}[/tex]
Taking the inverse (or reciprocal) of both sides gives us this:
[tex]\frac{x}{100} =\frac{2.5}{20}[/tex]
>> x=12.5\%
Therefore, 2.5 is 12.5% of 20.

Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.
[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]
Then inverse operation,
[tex]18x-18=180\\18x=198\\x=11[/tex]
After to get a, b, and c you just need to plug in x.
[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]

Answer:

Step-by-step explanation:
You have to work backwards. Take 565.2 and divide by 6. You get 94.2. You then divide that by pi or 3.14 and get 30. If you went the other way, 565.2 divided by 3.14 you would get 180. 180 divided by 6 is still 30.
Answer:
h = 5in
Step-by-step explanation:
So for this problem you kinda have to work backwords.
You would use the formula for finding the volume of a cylinder, except you are not finding you are finding the height.
volume of cylinder formula: V=π r² h
Start by plugging everything in:
565.2 = (3.14)(6²)(h)
565.2 = (3.14)(36)(h)
565.2 = (113.04)(h)
to slove for h you would need to get the varible alone, meaning you divide everything by 113.04.
h = 5in

28.73
Step-by-step explanation:

3πr3=4
3·π·1.93≈28.73091
Answer:
Step-by-step explanation:
Volume =
4 × π × r³ / 3 <----- This is our volume equation
= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)
= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9
= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")
= 86.1927360439 / 3 (Multiplied that by 4)
= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth
Answers
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

Find the value for q for the following equation: 15q – 16 = 4(2q + 3)
Answers
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4
Now your equation is 15q - 16 = 8q + 12
Step 2: Subtract 8q from both sides
Now your equation is 7q - 16 = 12
Step 3: Add 16 to both sides
Now the equation is 7q = 28
Step 4: Divid each side by 7

On Monday, 344 students went on a trip to the zoo. All 6
buses were filled and 8 students had to travel in cars. How many students were
in each bus ?
Answers
Answer:
56 students were in each bus is our answer
Step-by-step explanation:
This is true because if 8 students went in cars then we have to subtract 8 from 344, so we get 336 then from there we divide 6 from 336 giving us 56, thus 56 is our answer.
Your Welcome, Have A Splendid Day, And Hope This Helps!!!
if you subtract the 8 students from the total number you get 336
336 students divided by 6 busses equals 56 students in each bus
