Answer:
The % of of acid in solution = 63.88 ml
Step-by-step explanation:
The solution of acid and water = 351 milliliters
The % of of acid in solution = 18.2% of 351 ml
Or, The % of of acid in solution =
× 351 ml
Or, The % of of acid in solution = 63.882 ml
Hence ,The % of of acid in solution = 63.88 ml Answer
Answer:
4.6
Step-by-step explanation:
For this question, we need the opposite side and have the opposite
with that said, out of SOH, CAH, TOA it's fastest to use TOA
tan(75)=17/x
17/(tan(75))=x
x= 4.555136271
which rounds to
4.6
2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
2x + 6y = 18 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 + 8y = 24
8y = 24 ( divide both sides by 8 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 9
x + 9 = 9 ( subtract 9 from both sides )
x = 0
solution is (0, 3 )
Step-by-step explanation:
mean: (3 + 2 + 7 + 7 + 3 + 8 + 5 + 7 + 2 +8)/10 = 5.2
median: 2, 2, 3, 3, 5, 7, 7, 7, 8, 8 hence median is (5 + 7) / 2 = 6
mode: 7
