Answer:
39,270 ways.
Step-by-step explanation:
That is the number of permutations of 3 from 35.
35P3 = 35! / (35-3)!
= 35*34*33
= 39270.
The answer is D.
"A cube with the side lengths of 4 feet has a volume of 64 cubic feet."
the answer should be 24 because you can divide it into 2 shapes and solve them separately and add those products
Answer:
x=20
Step-by-step explanation:
The Pythagorean theorem is
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse.
The legs are x and 15 and the hypotenuse is 25
x^2 + 15^2 = 25^2
x^2 +225 = 625
Subtract 225 from each side
x^2 +225-225 = 625-225
x^2 = 400
Take the square root of each side
sqrt(x^2) = sqrt(400)
x = 20
The denominator can be 3 if the numerator is 1
