If you would like to find the unit rate, you can calculate this using the following steps:
$11.49 ... 3 packages
$x = ? ... 1 package
11.49 * 1 = 3 * x
11.49 = 3 * x /3
x = 11.49 / 3
x = $3.83
The correct result would be $3.83.
Answer:
523.33 cm³
Step-by-step explanation:
Formula of volume of sphere
The volume of the sphere
= 523.33 cm³ (rounded to the nearest hundredth)
2880 cubic inches is the answer.
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:
140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)
solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.
Let me know if I can clear anything else up.
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
