Answer:
The reciprocals of a number is sometimes called the Multiplicative Inverse of the number. The product of a negative number and its reciprocal equals 1. If the number is negative then the reciprocal must also be negative to produce a product of +1. The reciprocal of -4 is -1/4.
Step-by-step explanation:
Answer:
Fraction of fire trucks = ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Total number of toy cars = ![16](https://tex.z-dn.net/?f=16)
Step-by-step explanation:
Fraction of sports car = ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Fraction of remaining cars ![=1-\frac{2}{3}=\frac{3-2}{3} =\frac{1}{3}](https://tex.z-dn.net/?f=%3D1-%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B3-2%7D%7B3%7D%20%3D%5Cfrac%7B1%7D%7B3%7D)
So,
Fraction of pick up cars = ![\frac{1}{4}(\frac{1}{3})=\frac{1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%28%5Cfrac%7B1%7D%7B3%7D%29%3D%5Cfrac%7B1%7D%7B12%7D)
Therefore,
Fraction of fire trucks = ![\frac{1}{3}-\frac{1}{12}=\frac{4-1}{12}=\frac{3}{12}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D-%5Cfrac%7B1%7D%7B12%7D%3D%5Cfrac%7B4-1%7D%7B12%7D%3D%5Cfrac%7B3%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B4%7D)
That is Number of fire trucks =
( Total number of toy cars )
Number of fire trucks = 4
Total number of toy cars = ![4(4)=16](https://tex.z-dn.net/?f=4%284%29%3D16)
Answer:
trapezoid
Step-by-step explanation:
Well first 225/30 is 7.5 so you times 7.5 by any number till you get 150, which the answer is 20 minutes to burn 150 calories
work:
223/30 = 7.5
7.5 * 20 = 150
