Answer:
0.4545 or 45%
Step-by-step explanation:
Do-Gooders toys for boys = 5
Southside toys for boys = 6
Given that the first toy pulled out of the bin is a toy for boys, to find the probability that this toy was donated by the Do-Gooders, the number of toys for girls donate shouldn't be considered since there's a zero-chance that the toy in question is for girls. Therefore:
There's a 0.4545 or 45% probability that it was donated by the Do-Gooders.
56 units are in the sum of the lengths of the three altitudes in a triangle with sides $7,$ $24,$ and $25$
Properties of triangles are:
A triangle has three sides and three angles.
The sum of the angles of a triangle is always 180 degrees.
The exterior angles of a triangle always add up to 360 degrees.
The sum of consecutive interior and exterior angle is supplementary.

Given:
Height: ha = 7
Height: hb = 24
Height: hc = 25
Sum to sides is:
25 +7 + 24 =56 units.

The general form of an even number is 2n. So, odd number is 2n + 1 and 2n + 3.
Now, we have as the follows,
(2x + 1)(2x + 3) = 323
Or, 4x^2 + 6x + 2x + 3 = 323
Or, 4x^2 + 8x - 320 = 0
Or, x^2 + 2x - 80 = 0
Hence, the quadratic equation established is
That's it..
Answer:
81
Step-by-step explanation:
It will always be zero. Try plugging in a number for X. Let's say it's 1. So 6(1) - 6(1).... 6 - 6=0. Try some other values for you to prove it.
