Answer:
Step-by-step explanation:
The angle must be less than 180º
m∠FIE < 180
5x - 15 < 180
add 15 to both sides
5x < 195
Divide both sides by 5
x < 39
Therefor the first three choices are physically impossible
x = 21
the length and width of the rectangle is 30(length) and 20(width)
hope this helps
4.75 is your answer because you add 2,8,10,12 and then divide it by 4 equals 8 . Then divide 2,8,10,12 by 8 gives you the total of 6,0,9,4 add all that gives you a total of 19/4 equals your answer of 4.75
Answer:
36.81
Step-by-step explanation:
V= (2/3)pir
We know that
the formula for combinations is
nCr=n!/[(n-r)!*r!]
n is the total number of objects
r is the number that you choose to arrange
in this problem
n=5
r=2
C=5!/[(5-2)!*2!]------> C=5!/[(3)!*2!]-----> C=5*4*3!/[3!*2!]
C=20/2----> C=10 ways
the answer is
10 ways
