Answer:
12 and 1/4
Step-by-step explanation:
This is a fairly simply problem all you have to do is all all the fractions given. So we get the equation 4/8 + 5/8 + 5/8 + 1 1/8 + 1 1/8 + 1 4/8 + 1 4/8 + 1 4/8 + 1 6/8 + 2. This makes the equations easy since all the denominators are the same. First we must make all the fractions improper fractions. This will make the equation 4/8 + 5/8 + 5/8 + 9/8 + 9/8 + 12/8 +12/8 + 12/8 + 14/8 + 16/8. Then we can add all the values together and we get 98/8 which simplifies to 12 2/8 which further simplifies to 12 and 1/4.
I don't think it matters how many families are involved.
You're talking nine live births, and the probability of a
male birth each time is 50% .
So the probability of nine males in nine births is
(1/2)^9 = 1/512 = about <em>0.195 percent </em>(rounded)
Answer:
Step-by-step explanation:
person height/shadow length = lamp height / shadow length lamp
Person height = 164 cm
shadow length = 83
lamp height = x
lamp shadow length = 366 + 83 = 449
164/83 = x/449 Cross Multiiply
83x = 164 * 449 Combine Right
83x = 73636 Divide by 83
x = 73636/83
x = 887.18
Answer:
l think the answer is =C for this area of triangle
Ladder=10 feet
bottom of ladder=4 feet
hight of tree=x
by using pythogorean theorem
h^2=altitude^2+altitude^2
10^2=4^2+x^2
100=16+x^2
84=x^2
taking sqrt on both sides
9.2=x
hope this helps
