What are the coordinates of the midpoint of the segment with endpoints at (-3, -4) and (5, 8)?
lord [1]

Answer:

(4, ``6)

Step-by-step explanation:

The midpoint formula is

((x sub 2 - x sub 1)/2, (y sub 2 -y sub 1)/2). As shown, its written like a coordinate

Your x sub 1 is the x-coordinate of your first coordinate pair, and the rest follow the same pattern.

So, (5-(-3)/2, 8-(-4)/2)

5-(-3)=5+3=8

8-(-4)=8+4=12

(8/2, 12/2)

(4,6)

Help plzz I need the length of "b" and the answers and the steps to find that answer??? Plz help don't have a lot of time to sub
nadezda [96]

Answer:

Use pythagorean theorem.

Step-by-step explanation:

The length of the shorter sides are 1 & 4

1^2+4^2=c^2

1+16=c^2

17=c^2

So, the length, rounded to the nearest whole inch, would be 4.

To find the perimeter, you need to find the side lengths first.

The short sides are 6 & 7.

6^2+7^2=c^2

36+49=c^2

85=c^2

So the length for that would be 8, in the nearest whole number.

Add all of the side lengths together.

6+7+8= 21

The perimeter is 21.

In the expression 3(2^0), what is the order of operations? Explain how would you evaluated the expression.
Over [174]

We'll use PEMDAS which stands for

P = parenthesis

E = exponents

M = multiplication

D = division

A = addition

S = subtraction

It tells us the order in how to evaluate math expressions. We start with parenthesis, then move to exponents, etc until we get to subtraction as the last step.

We have parenthesis so we focus on whats inside it. We evaluate 2^0 to get 1. Any nonzero number to the exponent 0 is always 1. In other words, x^0 = 1 where x is nonzero.

So 3(2^0) turns into 3(1) or 3*1

Then we multiply that to get 3*1 = 3

So overall, 3(2^0) = 3

hram777 [196]

full timers work 5 hours a day whereas Part timers work 3 hours a day!

<u>Step-by-step explanation:</u>

Here we have , The difference in hours between full times and the part timers to work three hours a day is 2 working hours  . We need to find that  how many hours per day to full timers work . Let's find out:

Let full timers work x hours , Part time workers work 3 hours a day , According to question, difference in hours between full times and the part timers to work three hours a day is 2 working hours  i.e.

⇒ x-3 = 2

Adding 3 to make x term alone :

⇒ x-3+3 = 2+3

⇒ x=5

Therefore, full timers work 5 hours a day whereas Part timers work 3 hours a day!
