Answer:

(-8 , 3)

Step-by-step explanation:

(x1 , y1) (x2 , y2) = (-10 , -1) (-6 , 7)

$\frac{-6-10}{2}$ , $\frac{7-1}{2}$ -6 is going to be my x1 and -10 my y1

7 is going to be my x2 and -1 my y2

(-8 , 3)

Quadrilateral EFGH with diagonals EG and HF must be a parallelogram if (1) EF FG  and GH HE  (2) EG FH  (3) EG FH  (4) EF HG

qwelly [4]

Answer:

EF = HG and EF || HG

Step-by-step explanation:

A quadrilateral is a polygon shape with four sides and four angles.

A parallelogram is a quadrilateral with two pairs of parallel sides. The following are properties of a parallelogram:

Opposite sides are equal and parallel.
Opposite angles are equal to each other.
Consecutive angles are supplementary
The diagonals of a parallelogram bisect each other.

If Quadrilateral EFGH with diagonals EG and HF is a parallelogram then EF = HG and EF || HG

The area of a circular oil slick on the surface of the sea is increasing at a rate of [150m^2/s] how fast is the radius changing

Akimi4 [234]

Answer with Step-by-step explanation:

We are given that

$\frac{dA}{dt}=150m^2/s$

a.Radius =25 m

We have to find rate of change of radius.

We know that

Area of circle, $A=\pi r^2$

Differentiate w.r.t time

$\frac{dA}{dt}=2\pi r\frac{dr}{dt}$

Substitute the values then we get

$150=2\pi (25)\frac{dr}{dt}$

$\frac{dr}{dt}=\frac{150}{50\pi}=\frac{3}{\pi} m/s$

$\frac{dr}{dt}=\frac{3}{\pi} m/s$

b.A= $1000m^2$

Substitute the values then we get

$1000=\pi r^2$

$\pi=3.14$

$r^2=\frac{1000}{3.14}$

$r=\sqrt{\frac{1000}{3.14}}=17.8m$

$\frac{dA}{dr}=2\pi r\frac{dr}{dt}$

Substitute the values then we get

$150=2\pi(17.8)\frac{dr}{dt}$

$\frac{dr}{dt}=\frac{150}{2\pi(17.8)}=\frac{150}{35.6\pi}$ m/s

$\frac{dr}{dt}=\frac{75}{17.8\pi}$ m/s

A jeweler buys a ring from a jewelry maker for $125. He marks up the price by 135% for sale in his store. What is the selling pr

Elis [28]

Hey there!

First, you would multiply 125*135%= 168.75
Then you would add 125 to 168.75 and you would get 293.75.
Next, you would multiply 293.75*7.5%= 22.03
Finally, add 22.03 to 293.75 and your answer is...

$315.78

What is the measure of an angle if it is 260 less than three times its own supplement

Gala2k [10]

Answer:

130 degrees

Step-by-step explanation:

Let's assume that the angle is X. If angle is x, then:

x+260 = 3x

subtract x from both sides:

260 = 2x

130 = x because 260/2 is 130

so the answer is 130 degreees
