Answer:
8 sqrt(5)
Step-by-step explanation:
sqrt(45) + sqrt(125)
Rewriting
sqrt(9*5) + sqrt( 25 *5)
we know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9) sqrt(5) + sqrt(25) sqrt(5)
3 sqrt(5)+5 sqrt(5)
Add like terms
8 sqrt(5)
Use the Cosine Rule
q^2 = 20^2 + 30^2 - 2^20*30 cos 15
= 140.89
so q = sqrt 140.89 = 11.9 (answer)
3-1/2x=-71
when you solve it, the answer is 37
Answer:
13.7 cookies per cup
Step-by-step explanation:
Here, we want to write the constant of proportionality that relates the number of cookies to the
number of flours.
What we do
simply here is to divide the number of cookies by the number of cups of flowers
That would be;
y/x = 48 cookies/3.5 cups = 13.7 cookies per cup
