During a staff meeting, one department director reports that 24 people, representing 30% of department personnel, are
providing customer service that exceeds the company's standards.
How many people work in that department?
34
80
125
720
800

80

Step-by-step explanation:

The easy way to solve this is to find what 1% of the department is and then to multiply by 100, so:

30% = 24

30% / 30 = 24 / 30

1% = 0.8

1% * 100 = 0.8 * 100

100% = 80

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
