Answer:

The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run.

The slope formula is often shortened to the phrase “rise over run.”

garik1379 [7]

Answer:

It will take them 3.43 hours.

Step-by-step explanation:

Let T denote the total cookies that need to be cocked. Observe that:

If Rosanne finishes the cookies in 6 hours, that means that she can make $\frac{T}{6}$ cookies per hour.
If Dorothy finishes the cookies in 8 hours, that means that she can make $\frac{T}{8}$ cookies per hour.

Then, by 1) and 2), if they work together would we able to make

$\frac{T}{6}+\frac{T}{8}=\frac{8T+6T}{48}=\frac{14}{48}T=\frac{7}{24}T$

cookies per hour.

Therefore, in order to finish the T cookies they will need $\frac{24}{7}\approx3.43 hours$

find the measure of the angle of the radius of the circle is 4 inches and the length of the arc is 8 pi.

NeTakaya

Since the angle is in radians, then s = rθ.

$\bf \textit{arc's length}\\\\
s=r\theta \quad 
\begin{cases}
r=4\\
s=8\pi 
\end{cases}\implies 8\pi =4\theta \implies \cfrac{8\pi }{4}=\theta \implies 2\pi =\theta$

What is the product?<br>(4x) (-345 (-23)

olga_2 [115]

Answer:

Step-by-step explanation:

You first want to get rid of the numbers which are in parenthesis

(-345(-23)

This is a multiplication between negative numbers

The law of signs in mathematics states that negative times negative equals positive

(-) (-) = +

(-345(-23)= 7935

Then we multiply the number which is outside of the parenthesis (4x)

(4x)7935= 31740x
