Find two numbers whose arithmetic mean is 10 and geometric mean is 8

4 and 16

Step-by-step explanation:

Let a and b be two unknown numbers.

1. The arithmetic mean of these numbers is

2. The geometric mean of these numbers is

Solve the system of two equations:

From the first equation

Substitute it into the second equation

When

When

where are the choices?

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
