1. I feel the need to explain things first before I write the numeric value.
Let x be the total number of students in the school. 25% of this value is given to be 35.
(0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.
2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52
2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.
Answer:
160 cars
Step-by-step explanation:
The computation of the number of more cars he washed this year is given below;
Last year, he washed 20 cars a week so on yearly basis he washed
= 20 cars × 52 weeks
= 1,040 cars
And, this year he washed 1,200 cars
So, the number of more cars he washed this year is
= 1,200 cars - 1,040 cars
= 160 cars

Answer: Radio waves. Next longer is visible, ultraviolet, and shortest is x-rays.
Step-by-step explanation:
Just a fact. Radio waves also have the lowest energy and frequency. This is a physics question.
Wavelength = speed of light/frequency
Meters = meters per second / Hertz
= meters / second × seconds
Energy = Planck's constant times frequency.
