Answer:

Step-by-step explanation:

using Triangle Proportionality theorem, it states that if a constructed line parallel at one side of a triangle intersects the other two sides of the triangle and divides the remaining two sides proportionally; meaning

10:3x-5 = 8:28

<h2><u>10</u>    =   <u>8</u></h2><h2>3x-5     20</h2><h2>cross multiply</h2><h2>10 x 20 = 8(3x-5)</h2><h2>200 = 24x - 40</h2><h2>add 40 to both sides</h2><h2>200 + 40 = 24x - 40 + 40</h2><h2>240 = 24x</h2><h2>divide both sides by 24</h2><h2>240/24 = x</h2><h2>10 = x</h2><h2></h2><h2>b. perimeter is side + side + base</h2><h2>{10+(3x-5)} + {16} + {28}</h2><h2>since x =10</h2><h2>10+(3(10)-5)</h2><h2>10+30-5</h2><h2>40-5=35</h2><h2>35+16+28=79</h2>

Answer:

1 | 1

0 | -1

-1 | -3

2 | 3

Step-by-step explanation:

To fill the table, simply replace the x in the function with the value given.

For instance,

f(1) = 2(1) - 1 = 1

f(0) = 2(0) -1 = -1

f(-1) = 2(-1) - 1 = -2 - 1 = -3

f(2) = 2(2) - 1 = 4 - 1= 3

Answer now!!!!! Plz!!! In a recent year, 31.2% of all registered doctors were female. If there were 55,400 female registered doc
kotykmax [81]

Answer:

17285 female doctors

Step-by-step explanation:

We need 31.2% of 55,400 doctors to do this we multiply 31.2% by 55,400

0.312 is 31.2% as a decimal

so we do...

0.312 * 55,400 = number of female doctors

if type that into a calculator you get 17284.8

17.284 rounds to 17285

so the answer is...

17285 female doctors

Emily wins 22000$. She has to pay 10% for charity and then she decides to buy a car for 10800$. She divides the rest of them bet
devlian [24]

Answer:

$7 200

Step-by-step explanation:

Amount of money paid for charity = \frac{10}{100} × $22 000

                                                         = $2 200

Remaining money left for children = $22 000 - $2 200 - $10 800

                                                         = $9000

Let the amount of money her son receives be x and the amount her daughter gets be 4x.

Son's $ + Daughter's $ = $9000

x + 4x = 9000

5x = 9000

Amount of money her daughter gets (4x) = \frac{4}{5} × 9000

                                                                     = $7 200

A cottage has a gable roof. To the nearest foot, how wide is the cottage?A. 12 ftB. 24 ftC. 35 ftD. 70 ft
Sergio [31]

Answer: the answer is B: 24ft

Step-by-step explanation: To find how wide the triangle is identify your angles. You have a right angle which is equal to 90° and an angle that measures 46°. Add up both of these angles and you'll get 136°. A triangle can only have three angles that add up to 180. So subtract 180 and 136 you get 44. Multiply the hypotenuse by sin(46) to get the length of the side facing the opposite way of the angle that measures 44°. You will get 11.8 which is about 12. The other triangle is a congruent triangle meaning that it's angles and sides are the same. Add both 12's up and you have 24ft as your width for the cottage.
