13.45 + 9.5 = 22.95
42.6 - 22.95 = 19.65
19.65 : 3 = 6.55m did he fence each day wednesday thursday & friday
Total marbles: 1+ 4+3 = 8
Picking a blue marble = 4/8 = 1/2
Picking a second one: 1/2 x 1/2 = 1/4 probability
The correct answer is C.
When you have two fractions being divided, you can flip the second one and then multiply straight across. So in this case the top of your final answer would be the numerator of the first fraction multiplied by the denominator of the second:
(3x - 6)(2x - 1) = 6x^2 - 15x + 6
Then the bottom of your answer would be the denominator of the first fraction multiplied by the numerator of the second one:
x^3(x - 2) = x^4 - 2x^3
Answer: OPTION B.
Step-by-step explanation:
The missing figure is attached.
For this exercise you need to use the Pythagorean Theorem. This is:

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.
Then you can say that:

Therefore, knowing these values, you can substitute them into
:

Finally you must solve for PR in order to find its value. This is:
