You’re answer here is the third one
Answer:
-3/5
-1/2
-0.4
0.6
4/5
Step-by-step explanation:
For this question I converted the fractions to decimals.
-3/5 = -0.6
-1/2 = -0.5
4/5 = 0.8
Start off with the negatives, as they are the lowest numbers. <em>The further they are from zero the lower they get.</em>
-0.6 (-3/5)
-0.5 (-1/2)
-0.4
Now there are only <em>2</em> positive numbers, so order them.
0.6
0.8 (4/5)
Put it all together:
-3/5
-1/2
-0.4
0.6
4/5
Answer:
Step-by-step explanation:
Given
When mass = 4kg; Acceleration = 15m/s²
Required
Determine the acceleration when mass = 10kg, provided force is constant;
Represent mass with m and acceleration with a
The question says there's an inverse variation between acceleration and mass; This is represented as thus;
Convert variation to equality
; Where F is the constant of variation (Force)
Make F the subject of formula;
When mass = 4kg; Acceleration = 15m/s²
When mass = 10kg; Substitute 60 for Force
Divide both sides by 10
<em>Hence, the acceleration is </em><em />
Answer:
C. 20
Step-by-step explanation:
Let's say M is the original number of men and W is the original number of women.
M / W = 3 / 5
(M+2) / (W+1) = 2 / 3
Let's cross multiply both equations:
5M = 3W
3(M+2) = 2(W+1)
Let's simplify the second equation:
3M + 6 = 2W + 2
3M + 4 = 2W
From the first equation:
M = 3/5 W
Substitute:
3 (3/5 W) + 4 = 2W
9/5 W + 4 = 2W
4 = 1/5 W
W = 20
There were originally 20 women.
Let's check our answer. That would mean that M = 3/5 W = 12.
After 2 men walk in and 1 woman, W = 21 and M = 14, so 14/21 = 2/3. Looks like the answer is correct!
Answer C.
