We have $8.50 an hour gross minus $2.15 an hour tax and bennys.  Then $3.75 daily expense.  In one week our net take-away y after x hours is

y = x(8.50 - 2.15) - 5(3.75)

That's the answer, or we can simplify it to

Answer: y = 6.35 x - 18.75

Answer: The slope, 6.35, is the net dollars per hour <em>before weekly expenses.</em>

Answer: The y intercept, -18.75, is the weekly expense, negative because it's an expense.

To make $120 in a week, we solve for x where y=120

120 = 6.35x - 18.75

138.75 = 6.35 x

x = 138.75 / 6.35 = 21.8503937007874

That wasn't the nice round number I was expecting/hoping for.  I don't see a mistake so let's go with

Answer: 21.85 hours to make $120

Inessa [10]

Answer:

1/128 kilograms.

Step-by-step explanation:

First, multiply 16 and 4 to get 64. Since the weight of the box is 1/2 (or 0.5), so we have each cookie's weight at 1/128. Please mark this "brainliest" (the crown) if you like this answer!

The largest taco contained approximately 1 kg of onion for every 6.8 kg grilled steak. The total weight of these two ingredients
erastovalidia [21]

Answer: Onion = 79.17 kg

Grilled steak = 538.356 kg

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

1 k + 6.8 k = 617.6  

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.6

k = 617.6 /7.8  

k= 79.17

So:

Amount of onion used:

1 (79.17) = 79.17 kg

Amount of grilled steak used:

6.8 (79.17) = 538.356 kg

Feel free to ask for more if needed or if you did not understand something.

Suppose that α and β are the angles of a triangle. It is known that: 58°≤α≤59° and 102°≤β≤103°. Find the possible values of the
IceJOKER [234]

The possible values of the third angle are from 18° to 20°

Step-by-step explanation:

The sum of the measures of the angles in any triangle is 180°

The given is:

1. α and β are two angles of a triangle

2. 58° ≤ α ≤ 59°

3. 102° ≤ β ≤ 103°

Assume that the third angle is Ф

∵ α + β + Ф = 180°

- Subtract α + β from both sides

∴ Ф = 180 - (α + β) ⇒ (1)

∵ 58° ≤ α ≤ 59°

∵ 102° ≤ β ≤ 103°

- Add the two inequalities

∴ 160° ≤ α + β ≤ 162°

- By substituting α + B = 160 in equation 1

∴ Ф = 180 - 160

∴ Ф = 20°

- By substituting α + B = 162 in equation 1

∴ Ф = 180 - 162

∴ Ф = 18°

- Put Ф in the form of inequality

∴ 18° ≤ Ф ≤ 20°

The possible values of the third angle are from 18° to 20°
