Subtract exponents 9x10 3 -1x10 4

Answers

Answer 1

Answer: The answer to question is 9*10(-1) which is your exponent. The reason why it's a negative exponent is because when you subtract 3 and 4 you your answer would be negavite.Hope this helps:)

If two angles are both vertical and supplementary, then the angles are

Answers

we know that

Supplementary angles are those angles whose sum is equal to $180$ degrees and vertical angles are angles that are congruent.

Let

x--------> the first angle

y--------> the second angle

$x=y$ --------> equation $1$

$x+y=180$ --------> equation $2$

Substitute equation $1$ in equation $2$

$x+[x]=180$

$2x=180$

$x=90$

$y=90$

therefore

the answer is

the angles are right angles

ur answer would be RIGHT angle!!!

Hope its right!

Find the perimeter of the following rectilinear figure.

Answers

Answer:

Step-by-step explanation

You can't find the other sides, it may seem impossible, but you have to look at this problem in a different way. To find the perimeter of any figure you just need to know the top base, bottom base, right side, and left side.

We see that the top base equals to the bottom base as it is a rectilinear figure. You have to treat the side with 8 and side with 5 as one base. So they equal 13. Now do the same for the bottom.

So, 13 + 13 = 26

The right side is equal to the left side as it is a rectilinear figure, so the right side is 4 + 10 = 14. The left side is also 14.

So 14 + 14 = 28

26 + 28 = 54 units

Sorry, if I couldn't explain properly. I tried my best. As it is hard for me to explain in words. If I could draw it out, I could do better.

Answer:

Step-by-step explanation:

I broke the sections apart and then added:

14+14=28

13+13=26

26+28=54

Explain how to use a coordinate plane to find the area of a rectangle with vertices (–4, 9), (–4, –3), (–1, –3), and (–1, 9). what is the area?

Answers

We want to use a coordinate plane to find the area of the given rectangle.

We will see that the area is 36 units squared.

So we only know the vertices of the rectangle, which are:

(-4, 9)
(-4, -3)
(-1, -3)
(-1, 9).

The first thing we can do, is graph these in a coordinate axis so we can see our rectangle.

Below you can see the graph of the rectangle where the four vertices are graphed and I drew the sides of the rectangle.

Now that it is graphed is easy to see the measures of each side, one side measures 3 units (from -1 to -4 on the x-value) and the other side measures 12 units (from -3 to 9 on the y-value)

Then the area of the rectangle is:

A = 3*12 = 36 square units.

If you want to learn more about rectangles and areas, you can read:

brainly.com/question/17297081

the formula for area of a rectangle is

Area = length x width

since both the length and the width of the rectangle lie on the same x and y axis, we can find the distance between the width and the distance between the length by subtracting

(-4,9) (-4,-3)

these points lie on the same x axis, so they create a vertical line

9-(-3) = 12

12 units is the distance between them

(-4,-3) (-1,-3)

these points lie on the same y axis, so they create a horizontal line

-1-(-4) = 3

3 units is the distance between them

now that we have the length and the width, we can find the area

A = 12 x 3

A = 36 units²

A. $207.63
B. $310.27
C. $363.82
D. $313.37

Answers

$A = P(1 + (r)/(n))^(nt)$
$A = 200(1 + (0.05)/(12))^((12)(9))$
$A = 200(1 + (1)/(240))^(108)$
$A = 200(1(1)/(240))^(108)$
$A = 200(1.56684664942)$
$A = 313.369329884$
$A = \$313.37$
