The percentage of Samantha's suits that are green can be calculated by first creating a fraction. The numerator of this fraction should be the number of green suits, while the denominator would be the total number of suits. Green suits = 8 Total suits = 64 Fraction = 8/64
Now that we have a fraction representing how many green suits Samantha has, we can convert it to a decimal before finding the percent. To convert this fraction to a decimal, divide the numerator by the denominator. 8/64 = 0.125 In decimal form, 0.125 of Samantha's suits are green.
To finally convert this to a percent, we multiply the decimal by 100 and add a percent sign. 0.125 • 100 = 12.5 0.125 = 12.5%
In fraction form: 8/64 In decimal form: 0.125 In percent form: 12.5%
The answer is that 12.5% of Samantha's suits are green.
We write the kinematics equations a vf = a * t + vo rf = (1/2) * a * t ^ 2 + vo * t + ro We have then For the truck: a = 0 vf = vo rf = 45t For the car: a = 0 vf = vo rf = 60 * (t-15) Matching rf: 45t = 60 * (t-15) Clearing t: 45t = 60t-900 60t-45t = 900 15t = 900 t = 900/15 = 60h Answer: it will take for the car to catch up with the truck 60h
