Answer:
x = 4
y = 8
Step-by-step explanation:
this is a 30-60-90 triangle and the sides have a constant ratio
the side across from the 30°∡ is 1
the side across from the 60°∡ is √3
the side across from the 90°∡ is 2
In this problem we can find 'x' by setting up this proportion:
x/12 =
/1
cross-multiply:
x = 12
x = 12/
since we don't like to leave radicals in the denominator, we can multiply both numerator and denominator by
to get:
12
÷
·
(
·
=
, which equals 3)
so we have 12
/3, which is 4
The 'y' value will be twice the 30° side, so 8
Answer:
Y = 40%
R or G = 25%
O = 0%
Step-by-step explanation:
Total M&M's = 7+2+3+8 = 20
PY = 8/20 = .4 or 40%
P(R or G) = (2+3)/20 = 5/20 = .25 = 25%
PO = 0/20 = 0%
Answer:
8.5 hours
Step-by-step explanation:
Okay, so he made $71 last week including his $20 allowance. We can take out the allowance 71-20= 51 dollars made from babysitting. But they are asking us to find how many hours he worked.. knowing he gets paid $6 an hour we can divide 51/6 = 8.5 hours babysitting.
Hope this helps :)
