A:40%
If you put 60 over 150 and x(percent of students) over 100 and cross multiply 100 and 60, you will get 6000. You then divide that by 150 which leaves you with 40 as x and 40 over 100 is 40%.

ZE and ZF are vertical angles with mZE = 8x + 8 and mZF = 2x +38.<br> What is the value of x?
Dovator [93]

Answer:

Since ZE and ZF are vertical angles, they are congruent.

8x+8 = 2x+38

8 = 2x-8x+38

8 = -6x+38

8-38 = -6x

-30 = -6x

x = -30/-6

x = 5

Clark put 3000 in an account that compound 5% interest twice a year. if she left the money in for a year how much should have​
AlexFokin [52]

Step-by-step explanation:

A = P (1 + r/n) (nt)

   A = the future value of the investment/loan, including interest

   P = the principal investment amount (the initial deposit or loan      amount)

   r = the annual interest rate (decimal)

   n = the number of times that interest is compounded per unit t

   t = the time the money is invested or borrowed for

p = 3000

r = 5%/100 = .05 (has to be in decimal format)

n = 2

t = 1

A = 3000(1 + .05/2)⁽²ˣ¹⁾  note (make sure you use ^ (power of) for the 2x1)

use PEMDAS to work out problem

P arenthesis

E exponents

M ultiplication

D ivision

A ddition

S ubtraction

A = 3000(1 + .05/2)⁽²ˣ¹⁾

a = 3000(1 + .025)^²

a = 3000(1.025)^2

a = 3000 x 1.050625

a = 3151.875

she would have $3,151.88
