Solve for x. Assume that lines which appear tangent are tangent.
NeX [460]

Answer:

x=2

Step-by-step explanation:

The angle formed by two tangents intersecting outside of  a circle is half the difference of the intercepted arcs.

This implies that:

55=\frac{1}{2}(116x+3-(180-55))

We need to simplify this ad solve for x to get:

110=(116x+3-125)

Group the similar terms to  get:

110-3+125=116x

232=116x

Divide by 116 to get:

x=2

Gavin has 4 cups of mini cookies. He pours all of the mini cookies into 5 bowls so that each bowl has an equal amount.
alexandr1967 [171]

Answer:

4/5 cup

Step-by-step explanation:

Since he is putting an equal amount in each bowl, we can find the amount in each bowl by dividing 4 by 5.

This gets us 4/5

So, in each bowl, there is 4/5 of a cup of mini cookies

What is the y-intercept of the line?<br><br> x 16 24 32<br> y 44 64 84
Shtirlitz [24]

Answer:

The y-intercept of the line is 2

Step-by-step explanation:

You could try to find the slope of the line and then find the intercept with y axis by sloving b = y - ax

But here it seems easy enough once you see that the x values in the table increase by a factor of 8 and the y values in the table increase by a factor of 20.

(By the way, this is enough to give you the slope, because it is 8/20 ). But why bother?

Just extrapolate the table to the left, and you will find the y value where x = 0

x 0 8 16 24 32

y 2 22 44 64 84

So the y-intercept of the line is 2.

Extra:

The full equation of the line is:

y = 8/20x + 2
