√8
for the equations of circles: x²+y²= (radius)²
Answer:
Add all of the equations together and make them equal 180. (Solve for X) once you find x plug it back into each equation separately and that will tell you the answer for each angle
Step-by-step explanation:
Answer:
500 mL
Step-by-step explanation:
1 L = 1,000 mL
-> We use the formula of L * 1,000 = mL
1,000 mL / 2 = 500 mL
-> We only have half of the L, so we can divide it by 2 to get the correct number of mL

Answer:
D., x= 19.7 or ≈20. g
Step-by-step explanation:
P(x) = [100(15+x)]/(100+x)
When 0 g additional salt is added, x=0. we have
P(0) = [100(15+0)]/(100+0)= 15
x=0, P=15
We can see this point only on the graph D.
P(x) =29 = [100(15+x)]/(100+x)
29 = [100(15+x)]/(100+x)
29(100+x) = 100(15+x)
2900+29x = 1500+100x
2900-1500=100x-29x
1400 = 71x
x ≈ 19.7 g or ≈20. g
From the graph D, we can see that to get 29% we need to add ≈ 20 g of salt.
