Mhm.... Word problems.. So! Angle Side Angle :) proving that 2 triangles are equal. 
You need to prove that DC is equal to BA. Now....
DB == AC.
which you can subtract BC from both sides!
DB-BC = AC-CB. leaving you with DC= AB

Now by Side Angle Side, The angles are =, 2 sides are equal, means the 2 triangles are equal :) If the triangles are equal, the 2 remaining sides must be equal

Stephanie is a very good soccer player. She can kick a soccer ball with an initial velocity of 21.3 m/sec. The function that rep

If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.

-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>

mezya [45]

There are 150 students in Hannah's school.

Sum of books donated by the students =b.

Average books donated by each student =\frac{b}{150}

It is given Hannah donated 3 times as many books each student donated.

Number of books donated by Hannah= 3 times \frac{b}{150} = \frac{b}{50}

The expression of the number of books donated by Hannah= \frac{b}{50}

irga5000 [103]

Given that Jordan has a new puppy and she wants to put a fence around part of her yard to cover an area of 200 square feet.

Now we have to find what dimensions (length x width) should she make the rectangular area. None of the length or width are given so there can be lots of answers.

Since area is rectangular and we know that rectangle has different value of length and width so we just need to find two factors of given area 200 square feet.

For example 20 times 10 is 200.


So the dimension of the rectangular area will be:

Length = 20 feet and width = 10 feet


Now perimeter of the rectangle is given by formula:

Perimeter = 2(length+width) = 2(20+10)=2(30)=60


Hence perimeter is 60 feet.
