4:
5+4, 4+5, 6+3, 3+6
There is a total amount of 36 different ways so:
4/36 = 1/9 = 11.11%
We can write equations, using x and y as the length and width:
xy=40
2x+2y=26
Divide the second equation by two to get:
xy=40
x+y=13
Thus, x=13-y.
We now have (13-x)x=40, so
and
Factoring, we get:
(x-5)(x-8)=0
So, x can be either 5 or 8 (and y will be the other option). Thus, the length and width are 8 and 5.
The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?
Answer:
$96.15
Step-by-step explanation:
Let x be the wholesale cost of the bike.
Given:
Price tag of a bike = $125.
The bike store marks up the wholesale cost of all of the bikes they sell by 30%.
So we can find the wholesale cost of the bike by the following way.
Therefore, the wholesale cost of the bike is $96.15.
8^2 + 2 = 64 + 2 = 66
The answer is 66 because 8 to the second power is 64 and then you add 2.
