Answer:

The y coordinate is -3

Step-by-step explanation:

To find the midpoint, we use

midpoint = (x1+x2)/2, (y1+y2)/2

You only ask for the y coordinate.

y midpoint = (y1+y2)/2

y midpoint = (8+-14)/2

= -6/2

= -3

What is the probability that both ties he chooses are solid white

4vir4ik [10]

Answer:

$\frac{1}{25}$

Step-by-step explanation:

Total outcome is 10

Favorable outcome is 2

The probability to choose solid white tie is $\frac{1}{5}$

The probability that both ties he chooses are solid white is

$\frac{1}{5}$ × $\frac{1}{5}$ = $\frac{1}{25}$

How does brainstorm,decide,work,enjoy help with motivation?

Assoli18 [71]

Answer:

It helps because it gets you thinking. Personally, it would motivate me because that process itself is very helpful. Brainstorm will get you your idea, you can decide if you want to do it or not, then you work on it, and because you have the right attitude towards whatever you are working on, you'll enjoy it!

Answer:

The equations are:

$4H + 3P = 13.75$

$2H + 5P = 11.25$

$Hotdog = 2.50$

$Pretzel = 1.25$

Step-by-step explanation:

Let:

$H = hot\ dog$

$P =Pretzel$

For Tina:

$4H + 3P = 13.75$

For Doug:

$2H + 5P = 11.25$

Solving for the price of both items:

We have:

$4H + 3P = 13.75$ --- (1)

$2H + 5P = 11.25$ --- (2)

Multiply (2) by 2

2 * ( $2H + 5P = 11.25$ )

-------------------

$4H + 10P = 22.50$ --- (3)

Subtract (3) from (1)

$4H + 3P = 13.75$

$4H + 10P = 22.50$

----------------------

$4H - 4H + 3P - 10P = 13.75 - 22.50$

$3P - 10P = 13.75 - 22.50$

$-7P = -8.75$

Solve for P

$P = \frac{-8.75}{-7}$

$P = 1.25$

Substitute 1.25 for P in (2)

$2H + 5P = 11.25$

$2H + 5 * 1.25 = 11.25$

$2H + 6.25 = 11.25$

Collect Like Terms

$2H = 11.25-6.25$

$2H = 5$

Solve for H

$H = \frac{5}{2}$

$H = 2.50$

How do we find the area of a strange shape? Has six end points so it can become 4 triangles.

Sati [7]

In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!
