A college cafeteria pays student cashiers $10.20 per hour. Cashiers earn an additional $1.30 per hour for each hour worked over

nadya68 [22]

First week: 40 hours

Total Earning = 40 x $10.20 + (40 - 35) x $1.30 = $414.50

Second Week: 38 hours
Total Earning = 40 x $10.20 + (40 - 38) x $1.30 = $410.60

Total for the two weeks = $414.50 + $410.60 = $825.10

Answer: $825.10

A coin is tossed twice. Determine whether the events of getting two heads are independent or dependent. Then identify the indica

olya-2409 [2.1K]

Probability of getting heads on first try is 1/2
probability of getting heads on 2nd try is 1/2

probability of getting both is : 1/2 * 1/2 = 1/4
These are both independent because 1 does not effect the other

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

tamaranim1 [39]

Equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

Step-by-step explanation:

We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

The formula used for point-slope form is:

$y-y_1=m(x-x_1)$

We are given slope m = 4/5

Point (-7,9) where x₁ = -7 and y₁ = 9

Putting values in the formula:

$y-y_1=m(x-x_1)\\y-9=4/5(x-(-7))\\y-9=4/5(x+7)$

So, equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.
