What is the midpoint of AB?

Citrus2011 [14]

Answer:

$(-4, -\frac{1}{2})$

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as $(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

$x_1=-5\\y_1=-4\\x_2=-3\\y_2=3$

Now substitute those values into the formula:

$(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})$

$(\frac{-5+ -3}{2}, \frac{-4+ 3}{2})$

Now simplify the numerator and denominator

$(\frac{-8}{2}, \frac{-1}{2})$

Simplify again:

The midpoint is (-4, $-\frac{1}{2}$ )

Hope this helps!

Mrs. Miller spends 15% of each weekday traveling in her car. How many hours per day does she spend in her car during the week? (

andrezito [222]

Answer:

18 hours

Step-by-step explanation:

There are 24 hours in a day and we have 5 weekdays per week.

15% of 24 hours

15/100×24

0.15×24

=3.6 hours

Mrs Miller spends 3.6 hours of each weekday traveling in her car.

There are 5 weekdays in a week to include: Monday, Tuesday, Wednesday, Thursday and Friday.

If she spends 3.6 hours per weekday

Then,

During the week, she will spend

3.6 hours× 5 weekdays

=18 hours

She will spend 18 hours per week traveling in her car.
