A toy company spends $20 for every doll it makes. Promotion of the dolls costs $400 and the company sells each doll for $30. How
marissa [1.9K]

Since the company spends 20$ on each doll and sells each for 30$ thats a 10$ profit.

If the company spends 400$ on promotion it would take 40 dolls since

400$ / 10$(amount of profit per doll) = 40

so to make the promotion back it would be 40 dolls but the question was to make PROFIT so it must be 41 dolls

Answer:

\huge\boxed{x=17}

Step-by-step explanation:

It's important to note that when two angles create a straight line, they are supplementary.

This means their angle measures add up to 180° since a 180° angle is a straight line.

Since we know the measures of both angles in equation form, we can add them together and have them equal 180 to solve for x.

(5x-18) + (4x+45) = 180

Combine like terms:

9x + 27 = 180

Subtract 27 from both sides:

9x = 153

Divide both sides by 9:

x = 17

So x = 17.

Hope this helped!

umka21 [38]

The amount Levi spends on this skateboard is $148.39.

Tax is an amount levied on goods and services by the government. Taxes increases the price of goods and services.

The amount Levi spends on this skateboard = value of the tax + cost of the skateboard

value of the tax = 6% x $139.99

0,06 x $139.99 = $8.40

The amount Levi spends on this skateboard = $8.40 + $139.99 = $148.39

If cos theta=5/13 what is the value of tan theta for 0°&lt;theta&lt;90°​
Anna11 [10]

Answer:

12/5

Step-by-step explanation:

I hope this is right

1. we know cos = adjacent side / hypotenuse

2. therefore, adjacent side = 5 and hypotenuse = 13

3. using the pythag theorem, the missing side is 12, which is the opposite side

4. since tan = opposite / adjacent, the answer is 12 / 5
