When you cut along the diagonal, a right triangle is formed where the hypotenuse is the diagonal and the legs are the length and width of the rectangle (10 and 15 in this case)
Now use the pythagorean theorem to solve
10^2+15^2=325=c^2
c= approx 18.02775=length of the diagonal
The missing exponent is 2
Look at it this way:
When you flip a coin, the probability of it landing with EITHER side showing
is 100%.
This leads us to the rule ...
The sum of the probabilities of
all possible outcomes is 100%.
For a coin: (probability of heads) plus (probability of tails) = 100%.
That just says: We're 100% sure that the coin will land with either
heads or tails up.
An "honest" coin gets heads 50% of the time and tails the other 50%.
But if the coin is all bent and squashed and has a feather stuck to
one side and a wad of gum on the other side so that it comes up
heads 70% of the time, then the coin isn't 'honest'. But it still has to
land EITHER heads OR tails, so the sum of the probabilities is still 100%.
So the probability of heads is 30%.
She would make $324 for 18 hours of work
126 divided by 7 = 18
18*18 = 324
Answer:
The easiest way is to determine what number times 9 equals 15.
9x = 15
x = 15 / 9 = 5/3
The original number is 4 + 5/3 = 5 (2/3)
Then we look at the problem again,
5 and (2/3) minus 4 = 5/3 and
5/3 * 9 = 45/3 = 9
