Step-by-step explanation:

Quadrilateral MNPQ is shown.

Trapezoid M N P Q is divided into 4 triangles by N Q and M P, which intersect at point R inside the trapezoid. N P is parallel to M Q and M N is congruent to Q P. Angle N M P is 30 degrees and angle P M Q is 32 degrees. Segment Q R equals 4.1.

If MP = 5.9, what is RN?

(Round your answer to the nearest tenth. Write NA if there is not enough information given.)

Answers

Answer:4.1

Step-by-step explanation:

In the Quadrilateral MNPQ, if MP = 5.9, then RN = 1.8.

What is a trapezoid?

An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

Given:

Quadrilateral MNPQ is shown.

Trapezoid MNPQ is divided into 4 triangles by NQ and MP.

MQ is parallel to NP.

That means, MQ and NP always at the equal distance.

MN ≅ QP

So,

MP = QN

Now,

QN = QR + RN and QR = 4.1:

MP = QN

5.9 = 4.1 + RN

Then RN = 5.9 - 4.1 = 1.8

Therefore, the value of RN is 1.8.

24.5 is 33 1/3% of what number?

Answers

Answer: 73.5

Step-by-step explanation:

The percent 33 1/3% represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.

Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.

24.5 x 3 = 73.5.

Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!

Step-by-step explanation:

Write the problem as a mathematical expression.

m = -3, (7, -3)

Find the value of  b  using the formula for the equation of a line.

y = mx + b

b = 18

Now that the values of  m  (slope) and  b  (y-intercept) are known, substitute them into  y =  m x  +  b  to find the equation of the line.

y = -3x + 18
