Please Help!<br> The following is an isosceles trapezoid, find RS

patriot [66]

Answer:

<em>The length of RS is 47 units</em>

Step-by-step explanation:

<u>Midsegment Theorem</u>

The midsegment of a trapezoid is a line segment that connects the midpoints of the non-parallel sides.

The length of the midsegment of a trapezoid is the average of the lengths of the bases.

The midsegment of the given trapezoid is VW, and the bases are RS and UT.

According to the midsegment theorem:

$\displaystyle VW=\frac{RS+UT}{2}$

Substituting the variable lengths of the sides:

$\displaystyle 3x+5=\frac{2x+15+6x-37}{2}$

Operating:

$\displaystyle 3x+5=\frac{8x-22}{2}$

Dividing the fraction:

$3x+5=4x-11$

Rearranging:

$4x-3x=5+11$

Operating:

x=16

The length of RS is:

$RS=2x+15=2*16+15=32+15=47$

The lenght of RS is 47 units

45% of the student body at a local high school work part-time. 80% of the students who do not part-time love math whereas only 6

Mama L [17]

Answer:

71%

Step-by-step explanation:

I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.

Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.

44 + 27 = 71, so the percent is 71/100 = 71%.

let me know if any part of that doesn't make sense

Select three ratios that are equivalent to 11:111:111, colon, 1.<br> Choose 3 answers:

kirill115 [55]

The three ratios that are equivalent to the given ratio are options B, C and E.

<h3>How to determine the equivalent ratios?</h3>

In order to determine the ratios that are equivalent to the given ratio, we would evaluate by dividing each of them by their respective denominator value:

(11:111:111)/1 = 11:111:111.

For choice A, we have:

1:111:111/11 = 1/11:111:111 (not equivalent).

For choice B, we have:

22:222:222/2 = 11:111:111. (equivalent).

For choice C, we have:

55:555:555/5 = 11:111:111. (equivalent).

For choice D, we have:

9:999:999/99 = 1/11:111:111 (not equivalent).

For choice E, we have:

110:1110:1110/10 = 11:111:111. (equivalent).

Find the measure of each interior angle for MAT

Andrej [43]

*∠A= 180° - 105°= 75°

Now we have to find x:

Since ∠M, ∠A, ∠T are angles of a triangle, we know that:

M∠ + ∠A + ∠T = 180°

180° - (2x + 27°) + 75° + x - 8° = 180°

180° - 2x - 27° + 75° + x - 8° = 180°

220° - 1x = 180°

- x = 180° - 220°

- x = - 40°

x = 40°

*∠M= 180° - (2x + 27°)

= 180° - 2 × 40° - 27°

= 180° - 80° - 27°

= 73°

*∠T= x - 8°

= 40° - 8

= 32°
