In this big ol' word problem, this is just an instance of basic multiplication/division.
If it takes it 1 hour for 3 meters...
12 ÷ 3 = 4.
It would take 4 hours for the water level to change to 12 meters.
Answer:
457.6
Step-by-step explanation:
if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6
Let Mr Gelsomino lost g
Mr Chiarilli lost 240 more than g
so addition is to be used
or
#2
Just opposite
Mr Gelsomino lost 240 less than c
Answer:
40%
Step-by-step explanation:
A percent is;

It is given that Jolie the 75 dodgeballs in total, hence the whole is 75. It is also given that 30 of the dodgeballs hit the target, so the part is 30. Now all one has to do is solve for "x".

Simplify
by dividing the numerator and denominator by 15.

Now the equation is;

Typically, one would solve a proportion by doing cross products, but in this case, it is easier to think about it intuitively. Since 5 is a factor of 100 (5 * 20 = 100), then all one has to do is multiply
by 20 to get the answer (on the numerator).
x = 40
Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
