So we know that there are 1000 mL in 1 L. We can set up an equation that allows us to solve for how many bottles are needed in order to empty the 30 L tank:
This equation then allows us to cancel out the units of mL and L, leaving us with how many bottles are needed per tank. Then we multiply straight across to give us:
The question asks us to round up to the next whole number, so
it would take 86 bottles to empty one 30 L tank.
It depends what your trying to get close to. If your trying to get close to a number that is easier to work with 1 4/8 is good because its the same as 11/2 but the closest whole number is 1.
The absolute value of a number is its distance from 0. An easy way to think about this is that the absolute value turns a negative number positive, and has no effect on positive numbers. In this case, we are taking the absolute value of a negative number. This means we should simply make the number positive. Therefore, the answer is
Answer:
x = -8
Step-by-step explanation:
5(x - 1) = -45
5x - 5 = -45
add 5 to each side of the equation:
5x = -40
divide both sides by 5:
x = -8
The equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10
The number of campers last year is 400.
<h3>What are percentages?</h3>
Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. Percentages are used to measure frequency.
<h3>How many campers attended last year?</h3>
The number of campers last year = number of campers this year / (1 + percentage increase)
440 / 1.1 = 400
