Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
You kind of have two ways to do this:
Way 1:
Find how many 60 cents fit into $4. To do that, divide $4 by $0.60 or 400 by 60. You get 6.66666667.
You can divide 100 by 6.66666667, and get 15%,
Way 2:
Knowing that 400 cents is 100%, you can divide 60 by the same number that you divide 400 by to get to 100. To get from 400 to 100, you divide by 4, so divide 60 by 4 and get the same answer, 15%
Hope that helps :)
Answer:
24. x = 8.
25. x = -9, 10.
Step-by-step explanation:
The zeros of the functions are the solutions to the equation when y=0. To find the solution, factor each equation.
24. Look for two factors that multiply to 64 and add to -16. The factors are -8 and -8. Write them in binomial forms.
(x-8)(x-8)
So x = 8.
25. Look for two factors that multiply to -90 and add to -1. The factors are 9 and -10. Write them in binomial forms.
(x+9)(x-10)
So x = -9, 10.
