Step-by-step explanation:
Answer: Each fundraiser need to raise $ 135.59 in order to purchase the new net and equipment.
Step-by-step explanation:
Money required = $ 842.36
Donation amount = $ 300.00
Amount left to arrange = (Money required - Donation amount )
= $ (842.36- 300.00)
= $ 542.36
Number of fundraisers = 4
Money required to arrange by each fundraiser = (Amount left to arrange) ÷4
= $ (542.36÷4)
= $ 135.59
Hence, each fundraiser need to raise $ 135.59 in order to purchase the new net and equipment.
This one can besolved using system of equations. From the first statement we can assume that
length = 2 * width. The area of rectange equals product of it's width and length. By knowing that and following to the second statement we get the second equation:
(3 * width) * (length - 5) = width * length + 4. Let's mark the
width as
x and the
length as
y and write down our equations system:
Using substituion method, lets replace every
y with
2x within second equation and solve it:
Now lets find the discriminant in order to solve this quadratic equation:
The second root is negative, so we ignore it as
x represents width which can't be negative.
Now, using found root, let's find
y value from the first equation:
So,
the width is equal 4 (and the length is equal 8).
To find the sum of the interior angles of a hexagon, divide it up into triangles. The sum of each triangle is 180 degrees.
We get.... 4 x 180°=720°
So to sum it up....the sum of the interior angles of a hexagon is 720 degrees.
