This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
Answer:
425
Step-by-step explanation:
Out of 429 matchbox cars, there's only 4 that are blue. Therefore, 429 - 4 = 425. :)
You can rearrange f(x) as:
f(x) = 3(x^2 + 3x) + 12 = 3(x+1.5)^2 +5.25
So you can see the vertex is at (0,5.25) when x = -1.5
The axis of symmetry then lies in x = -1.5
If you are trying to find the percentage he received: 58/100
Total correct divided by total questions.
You get .58 or
58% by moving the decimal to spaces to the right.
