What is the midpoint of the line segment with endpoints (–1, 7) and (3, –3)?

Kipish [7]

The coordinates consist of x coordinate and y coordinate
(x₁,y₁) = (-1,7)
(x₂,y₂) = (3,-3)

To find the midpoint of x coordinate, use this following formula
x midpoint = (x₁ + x₂)/2
x midpoint = (-1 + 3) / 2
x midpoint = 2/2
x midpoint = 1

To find the midpoint of y coordinate, use this following formula
y midpoint = (y₁ + y₂)/2
y midpoint = (7 + (-3))/2
y midpoint = (7 - 3)/2
y midpoint = 4/2
y midpoint = 2

ANSWER
The midpoint is (1,2)

The measure of an angle is seventy-one times the measure of a supplementary angle. What is the measure of each angle?

steposvetlana [31]

Let the smallest angle = x

Then the larger one = 71x

Supplementary angles are always equal to 180o

x + 71x = 180o Add the left side

72x = 180 Divide by 72

x = 180/72

x = 2.5

The smallest angle = 2.5 degrees

The largest angle = 2.5 * 71

The largest angle= 177.5 degrees.

It has been estimated that the population of Indianapolis is growing at a rate of 0.9% per year. Assuming that population growth

Mumz [18]

Answer:

2,136,605

Step-by-step explanation:

To estimate growth, we use the formula shown below:

$F=P(1+r)^t$

Where

F is the future amount (we want to find for Jan 2024)

P is the present amount (present population of 1,988,817)

r is the rate of growth (0.9% means 0.009)

t is the time in years (from Jan 2016 to Jan 2024 is 8 years, t = 8)

Let's put these into the formula and figure out F:

$F=P(1+r)^t\\F=1,988,817(1+0.009)^8\\F=2,136,604.5$

Rounding we get the population in Jan 2024 to be 2,136,605

Alan just got a Fall job. The equation P = 12.50h represents the salary P (in dollars) he will earn when he works h hours. How m

balandron [24]

Given:

Alan salary P (in dollars) when he works h hours is represented by the equation

$P=12.50h$

To find:

The earning per hour.

Solution:

We have,

$P=12.50h$

Here, P is total salary and h is number of hours he works.

$\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}$

$\text{Earning per hour}= \dfrac{12.50h}{h}$

$\text{Earning per hour}=12.50$

Therefore, the earning per hour is $12.50.
