4 overtime hours - regular pay + $40

Total $ earned - $160

Total hours - 12 hours (8 reg + 4 overtime)

$160 - $40 = $120

$120/12 = $10

Her regular pay is $10 per hour.

Let x be Kelly's regular pay

Her pay for the day can be modelled by the equation 8x + 4(x + 10) = 160

Solve for x

8x + 4x + 40 = 160
8x + 4x = 160 - 40
12x = 120
x = 10

Kelly's regular pay per hour is $10

What is the probability of rolling a product of 30 when rolling two dice?
Nimfa-mama [501]
It has a probability of 2 out of 36 chances as there are only two ways it can happen out of 36 different combinations that can be rolled. Product means multipication also in Maths 

<span>The first probability on the first roll is that Dice 1 must be a 5 and Dice 2 must be a 6 so that 5x6=30 </span>

<span>The second probability on the second roll is that Dice 1 must be 6 while Dice 2 must be 5 so that 6x5=30 </span>

<span>That is the only two ways out of 36 different combinations that can be made by rolling to Die. Therefore the probability is 2 out of 36

Tamiku [17]

Answer:

x = $5.49 cost of the bananas

Step-by-step explanation:

x = cost of the bananas

$3.89 = cost of the peanut butter

$ 9.38 is the cost of both

Bananas + peanut butter = $9.38

    x         +   $3.89           =   $9.38

   <u>             - $ 3.89            =  -$3.89      </u>    Subtract $3.89 from both sides

      x                                 =  $5.49

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who h
joja [24]

Answer:

Angle of elevation = 80°

Step-by-step explanation:

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?

To solve for angle of elevation, we use the Trigonometric function of Tangent.

tan θ = Opposite side/Adjacent side

Opposite side = Height of the tower = 217 ft

Adjacent side = 38ft

tan θ = 217/38

tan θ = 5.6315789474

θ = arc tan 5.6315789474

= 79.930937301°

Approximately = 80°
