X would be 31 degrees

180-118 = 62
62/2 = 31 degrees
(you divide by 2 because the sides are congruent)

Well since a coin has two sides, heads and tails, the probability of getting tails would be 50%.

Give coordinates X(3,-4) and Y(-3,-4), midpoint D of XY is?

Lady_Fox [76]

Answer:

$\large\boxed{D.\ D(0,\ -4)}$

Step-by-step explanation:

The formula of a midpoint of the segment"

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

We have the points X(3, -4) and Y(-3 -4).

Substitute:

$x=\dfrac{3+(-3)}{2}=\dfrac{0}{2}=0\\\\y=\dfrac{-4+(-4)}{2}=\dfrac{-8}{2}=-4$

Find the distance between points A and F

lesya [120]

Answer: $2\frac{1}{4}$

This is the mixed number 2 & 1/4

whole part = 2

fractional part = 1/4

=======================================================

Explanation:

Each tickmark represents $\frac{1}{4}$

If you count the spaces between points F and A, you should count out exactly 9 spaces as shown in the diagram below.

We'll multiply that value 9 by $\frac{1}{4}$ to get our final answer.

$9*\frac{1}{4} = \frac{9}{4}$

$\frac{9}{4} = \frac{8+1}{4}\\\\\frac{9}{4} = \frac{8}{4}+\frac{1}{4}\\\\\frac{9}{4} = 2+\frac{1}{4}\\\\\frac{9}{4} = 2 \frac{1}{4}\\\\$

The result we get is a mixed number 2 & 1/4, meaning the whole part is 2 and the fractional part is $\frac{1}{4}$
