Answer: 1.25 dollars per roll

Step-by-step explanation:

If the relationship is graphed with the number of rolls sold on the x-axis and the money earned on the y-axis

Then the two points on that line will be (14,17.50) and (16,20)

We know that the slope of a lien with points $(x_1,y_1)\ and\ (x_2,y_2)$ is give by:-

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Hence, the slope of the graph with points (14,17.50) and (16,20) is given by :-

$Slope=\frac{20-17.50}{16-14}=\frac{2.50}{2}=1.25$

Therefore, the slope of the graph = 1.25 dollars per roll.

In radian measure, the angles of a 45-45-90 triangle are:

jeka94

Answer:

The answer is the option A $\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}$

Step-by-step explanation:

we know that

The measure of $\pi$ radians is equal to $180\°$

so by proportion

Find the measure in radians of $45\°$

$\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{45}\frac{radians}{degrees}\\ \\x=(45/180)*\pi \\ \\x=\frac{\pi}{4}$

Find the measure in radians of $90\°$

$\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{90}\frac{radians}{degrees}\\ \\x=(90/180)*\pi \\ \\x=\frac{\pi}{2}$

therefore

In radian measure the angles are

$\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}$
