Answer:

AHH! Geometry!

Thanks!

The arc has a length of 1/3

Step-by-step explanation:

So you first start off with this:

$\frac{20}{360}$

This is because a circle is 360 degrees, and we are talking about a 20 degree arc.

Simplifying, we get $\frac{1}{18}$

So then, you multiply the circumference with this "factor"

$\frac{1}{18} *6=\frac{6}{18}=\frac{1}{3}$

Hope this helps!

P.S. Stay Safe during quarantine!

Which expression means the same as "subtract 3 from 7 and then multiply

marishachu [46]

Answer:

A 4* (7 - 3)

Step-by-step explanation:

Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.

7 - 3

Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.

(7-3) x 4

4 * (7-3)

The answer is A.

Answer:

y-intercept: (0, 3)

Step-by-step explanation:

Attached is a screenshot of the plotted points (-1, 1) and (1, 5) on a graph. It shows that the line crosses the y-axis at point (0, 3) → which is the y-intercept.
