Answer:

See explanation

Step-by-step explanation:

A <u>parallelogram</u> is a quadrilateral with parallel opposite sides. The main property of a parallelogram is that the opposite sides of the parallelogram are congruent.

1. Sides AB and CD are congruent, then

4x=18\\ \\x=\dfrac{18}{4}=4.5

2. Sides AD and BC are congruent, so

\dfrac{1}{3}x=7\\ \\x=7\cdot 3=21

3. Sides AD and BC are congruent, so

x+4=15\\ \\x+4-4=15-4\\ \\x=11

To change the number of students that are girls into percentage...

17/1 * 1/100 = 17/100

Please help me solve this (ASAP)
joja [24]
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.

Thus, lets form an equation:

90 = 5x + 19 + 4x - 1
72 = 9x
x = 9

Thus, the measure of angle B is 64°.

Can someone help me I’m having trouble finding the area of the shaded region in each figure and round the answer to two decimal
stellarik [79]

Answer:

Step-by-step explanation:

Area of a Semi Circle

Area = 1/2 pi r^2

r = d/2

r = 3/2

r = 1.5

Area = 1/2 3.14 * 1.5^2

Area = 1/2 * 3.14 * 2.25

Area =                                                           3.5325

Area of Rectangle

L = 12 Yd

W = 4 Yd

Area = L * W

Area = 12 * 4<u>  =                                          48 </u>

Total Area =                                               51.5325

paul is diving and is 3.5 feet below sea level. he is descending at a rate of 0.5 feet per minute. if paul is now at 12 feet how
andrezito [222]

Answer:

He has been diving for 17 minutes

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- Paul is diving and is 3.5 feet below sea level

- He is descending at a rate of 0.5 feet per minute

- Paul is now at 12 feet

∵ His initial position is at 3.5 feet below the sea

∵ He is descending, that means he is moving down

∵ His final position is at 12

∴ <em>He is descending a distance = 12 - 3.5 = 8.5 feet</em>

∵ He is descending at a rate of 0.5 feet per minute

∵ He is descending 8.5 feet

∵ <em>Time = distance ÷ rate</em>

∴ <em>His time of descending = 8.5 ÷ 0.5 = 17 minutes</em>

* <em>He has been diving for 17 minutes</em>
