If parallelogram JKLM is rotated 270 clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side JM in the imagine parallelogram?

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

I think you missed attaching the photo of the parallelogram JKLM and here it is in my answer

When rotating a point 270° clockwise or 90°clockwise around the origin, we apply the rule (x, y) → (-y, x).

Look at the photo, we can see the coordinate of the point

J (-6, 2)

M = (-5, -1)

So apply the rule, after the rotation, the new co-ordinates will be:

J = (-2, -6)

M = (1, -5)

Answer 2

Answer:

Answer: A j(-2, -6) and M(1,-5)

during a basketball game, your team scored three times as many 2-point field goals than it did 3-point field goals, and scored a total of 90 points. How many field goals did your team score?

Answers

Answer:

40 field goals

Step-by-step explanation:

Represent 2-point with x and 3-point with y;

Given

$x = 3y$

$2x + 3y =90$

Required

Determine x and y

$x = 3y$

$2x + 3y =90$

Substitute 3y for x in $2x + 3y =90$

$2(3y) + 3y = 90$

$6y + 3y = 90$

$9y = 90$

Divide both sides by 9

$y = 10$

Substitute 10 for y in $x = 3y$

$x = 3 * 10$

$x =30$

The number of field goals = x + y

$x + y = 30 + 10$

$x + y = 40$

Hence, the number of field goals is 40

Answer:

1895.22 feet^2

Step-by-step explanation:

So starting off we will find the area of the hexagon.

The formula is complicated so I won’t write it.

The area is 509.22 feet^2.

Now for the triangles.

So the base is 14 feet and the height is 33 feet.

After multiplying them and dividing them by two I got 231 feet^2.

Then multiplying 231 by 6 I got 1386 feet^2.

So adding up 1386 and 509.22 I got 1895.22 feet^2.

-N/5=5

Can someone explain this to me?

Answers

Hi! First, we multiply both sides by 5, -n/5*5=5*5=-n=25. Second, we divide both sides by -1, -n/-1=25/-1. Therefore, our answer is n=-25

Suppose that the cost of a paving stone is $2.50 plus $.18 for every 4 in.³ of concrete how much would each paving stone cost ?

Answers

We need to know the dimension of the paving stone.

For example, the paving stone is shaped like a rectangular prism with the following dimension.

Length = 10 inches
Width = 3 inches
Height = 2 inches

Volume of a rectangular prism = Length * Width * Height
V = 10 in * 3 in * 2 in
V = 60 in³

60 in³ / 4 in³ = 15

cost of paving stone = 2.50 + .18(15) = 2.50 + 2.7 = 5.20 per paving stone.
