Answer:

14: B. 40 C. 40 D. 100

Step-by-step explanation:

a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.

To double check just add 100+40+40=180

Answer:

point B

Step-by-step explanation:

isolate the x to solve for x:

=> x = 1 - $\frac{3}{4}$

=> x = $\frac{1}{4}$

point B=> the half of $\frac{1}{2}$ is $\frac{1}{4}$ => $\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{4}$

Throughout this, I'm assuming that the scale is: 1 square = 1

Not 100% sure if my answers are correct.

The x coordinate would be -2 and the y coordinate would be -1.

There are 99 males and 121 females participating in a marathon. What percent of the participants are female?

ioda

To do this, we first want to see how many participants there are in total by adding both males and females.

$99+121=220$

Now we know that there were 220 total participants, but only 121 were females.

This allows us to set up the fraction 121/220= the percent female.

$\frac{121}{220} =0.55$

or 55%
