Answer:
Rounding to the nearest minute, it would take 95 minutes, or 1 hour and 35 minutes.
Step-by-step explanation:
Let's convert each time to minutes:
3.2 hours = 192 minutes
80 minutes = 80 minutes
2 hr 20 min = 140 minutes
Next, let's find the least common multiple:
LCM(192, 80, 140) = 6720
So let's say the volume of the tank is 6720 units. The speed of each pump is therefore:
Pump 1 = 6720 units / 192 minutes = 35 units/minute
Pump 2 = 6720 units / 80 minutes = 84 units/minute
Pump 3 = -6720 units / 140 minutes = -48 units/minute
Their combined speed is:
35 + 84 − 48 = 71 units/minute
So the time to fill the tank is:
6720 units / (71 units/minute) = 94.65 minutes
Rounding to the nearest minute, it would take 95 minutes, or 1 hour and 35 minutes.
Answer:
If my thinking is right she should weigh about 18 pounds or so.
Step-by-step explanation:
17% of 174 is 29
17% of 108 is 18
try this for answer (11×3.5)-9=x
The volume of rectangular prism is the product of its length, width and height.
So the volume V of prism with length

yards, width

yards and height of 4 yards will be:

Thus the volume of prism as a mixed number in simplest form will be

cubic yards
Answer:
A
Step-by-step explanation:
In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.
The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.
Since 0.85 is already in decimal form, leave it as it is.
3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:

Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.
91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.
Now that you can see the numbers, just rearrange them from least to greatest
0.75<0.85<0.91
equal to A
