Answer:

8 hundred dollars

Step-by-step explanation:

The break even value means zero profit or loss over the five years period. So if 2017 profit is x, then we get:

2.5 + 1.4 - 3.3 - 1.4 + x = 0
x - 0.8 = 0
x = 0.8 thousands of dollars
x= 800 dollars

I found some shirts for Jonah that were 40 percent of their regular price I bought him 3 shirts and each one was regularly price

Alekssandra [29.7K]

Answer:

32.40

Step-by-step explanation:

The shirts were 40% of the regular price

The sale price of 1 shirt was

18*40% = sale price

18*.40 =7.20

He bought 3 shirts, so multiply by 3

3 * 7.2 =21.60

He paid 21.60

The price he would have paid without the discount is

18*3 = 54

The savings is

54- 21.60 =32.40

What is the rate of change between (1,15) (3,45)?

Ksivusya [100]

Answer:

15

Step-by-step explanation:

Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:

(y2 - y1)/(x2 - x1)

=> Rate of change of the line passing (1,15) and (3,45):

(45 - 15)/(3 - 1) = 30/2 = 15

Please help me find the value of x the answer must be exact

jenyasd209 [6]

Answer:

$x=11$

Step-by-step explanation:

This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:

$leg=x\\hypotenuse=x\sqrt{2}$

Therefore, the value of x is 11.

You can double-check using the sine ratio:

$sineX=\frac{opposite}{hypotenuse}$

Insert the values:

$sin45=\frac{x}{11\sqrt{2} }$

Insert the equation into a calculator:

$x=11$

:Done

*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.
