Answer: concentration = 15.58%
Step-by-step explanation:
Given: mass of sugar = 24 g = 24 ml [ ∵ 1 g = 1 ml]
Volume of solution = Quantity of water + quantity of solute
= 130 +24 ml
= 154 ml
Concentration = 

Hence, the concentration =15.58%
Answer: 2x+3y = -6
Good luck !
Answer:
Concept: Mathematical Analysis
- 2 friends share 56
- 5- 10 dollar bills and 6- one dollar
- We split the bills in half to equate equal change.
- Hence 5 bills ÷2= 2.5 or 25 dollars
- 6 bills÷2= 3 or 3 dollars
- You need to make change for the 10 dollars, break a bill into 5's
Answer:
= 12x³ - 6x² - 7
Step-by-step explanation:
Differentiate each term using the power rule
(a
) = na
Given
y = 3
- 2x³ - 7x + 5, then
= 4.3
- 3.2
- 7
+ 0
= 12x³ - 6x² - 7
