Answer:

b 125

Step-by-step explanation:

first you know that you have 2 and 5 as similar numbers you both square them so that they become a ratio of area which is 4/25 after you do 4/25=20/x and you do cross multiply then you find 125. hope that helped understand.

Answer:

B.

Step-by-step explanation:

o find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

The true statements about ∠MJK and ∠MJL are

The sum of the two angles is 180 degrees
JK and JL are opposite rays
JK and JL form a straight line

<h3>How to determine the true statements?</h3>

The statement is given as:

∠MJK and ∠MJL are a linear pair of angles and the angles are also supplementary

As a general rule, linear pair angles are adjacent angles that add up to 180 degrees. This means that:

They are supplementary angles
They have a sum of 180 degrees
The angles may or may not be congruent
They have opposite rays i.e. straight line

The above means that, the following options are true:

(e), (f) and (h)

Also, the converse of the statement is:

∠MJK and ∠MJL are supplementary angles and the angles are also linear pair of angles

This is false because not all supplementary angles are linear pair angles

Factor expression gcf 90y+65z?

Vinil7 [7]

Answer:

5(18y + 13z)

Step-by-step explanation:

The GCF (Greatest Common Factor) of 90 and 65 is 5.

90 / 5 = 18

65 / 5 = 13

5(18y) = 90y

5(13z) = 65z

5(18y + 13z)

the stairway to a cellar has a slope of -4/3, and the cellar is 2m below the ground. the equation y=-4/3x-2 models the stairway.

8_murik_8 [283]

Shown below

<h2>Explanation:</h2>

The stairway to a cellar has a slope of -4/3, that is:

$m=-\frac{4}{3}$

On the other hand, the cellar is 2m below the ground. In other words:

$y-intercept: \\ \\ b=-2$

So this can be modeled by the equation of the line:

$y=-\frac{4}{3}x-2$

The line has a y-intercept at point (0, -2) and as x increases 3 units y decreases 4 units. So:

$x=3 \\ \\ y=-\frac{4}{3}(3)-2=-6 \\ \\ (3,-6) \ is \ also \ a \ point \ on \ the \ line$

Finally, let's draw a line that passes through:

$(0,-2) \ and \ (3,-6)$

By using graphing tool, we get the line shown below.
