Answer: 0.7893g//mL
If 20 mL of ethanol (density =0.7893g//mL) is mixed with 40mL water (density = 0.9971g//mL)
Step-by-step explanation:
<span>8.5 +4(1-2.5k) = -24.5
Use distributive property
8.5 + 4 - 10k = -24.5
Add 4 to 8.5
12.5 - 10k = 24.5
Subtract 12.5 from both sides
-10k = 12
Divide -10 on both sides
Final Answer: -12/10 or -1 2/10 or -1 1/5 *All answers are equivalent to each other.</span>
Answer:
Step-by-step explanation:
Slope of line through (5,4) and (3,7) = (7-4)/(3-5) = -1.5
Point-slope equation of line:
y-4 = -1.5(x-5)
Convert equation to standard form:
y-4 = -1.5x + 7.5
1.5x + y = 11.5
3x +2y = 23
Answer:
There are 5 yellow balls
Step-by-step explanation:
40/4 = 10
10/2 = 5
For each of the ordered pairs, the x coordinate is squared to find y.
x = 1
1^2 = 1
x = 2
2^2 = 4
x = 3
3^2 = 9
x = 4
4^2 = 16
