Answer:
28/289
Step-by-step explanation:
7 red, 4 blue, and 6 white = 17 marbles
P ( red ) = number of red / total
= 7/17
Replace the marble
7 red, 4 blue, and 6 white = 17 marbles
P ( blue ) = number of blue / total
= 4/17
P (red, replace, blue) = 7/17* 4/17
=28/289

Make bottom numbers same
find least common multipules of 8,12,4 and 3
8=2 times 2 times 2
12=2 times 2 times 3
4=2 times 2
3=3
lcm=2 times 2 times 2 times 3=24
5/8 times 3/3=15/24
5/12 times 2/2=10/24
3/1 times 24/24=72/24
1/4 times 6/6=6/24
2/3 times 8/8=16/24
we now have
15/24-10/24(72/24-6/24)+16/24
pemdas
simplify parenthasees first
72/24-6/24=66/24
now we have
15/24-10/24(66/24)+16/24
multiply
15/24-660/576+16/24
make same bottom number
15/24 times 24/24=360/576
16/24 times 24/24=384/576
360/576-660/576+384/576
84/576
7/48
answer is 7/48
Answer:
60, 36, 84
Step-by-step explanation:
The angles of a triangle always add up to 180 degrees.
If the ratios are 5:3:7, that means that there are 15 pieces that we can break up the 180 degrees by.
180/15 = 12
Each value is 'worth' 12 degrees.
Thus the angles would be the ratios multiplied by 12.
5 x 12 = 60
3 x 12 = 36
7 x 12 = 84
