Answer:

6.6h

Step-by-step explanation:

  • So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 miles
  • Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
  • 330 miles divide by 50 miles per hour gives 6.6 hours

So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure
Iteru [2.4K]

I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.

Let's start with the bottom,

a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)

Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)

And anything to the 0th power is 1, so your answer should be 1

Hope that helps!

A, B and C can do a piece of work in 20, 30 and 60 days respectively. In how many days can A do the work if he is assisted by B
Goshia [24]

A, B and C working together will finish same piece of work in 10 days

A can do a piece of work in 20 days. That is A is doing the work at a rate of  1 / 20. Therefore

B = 1 / 30

C = 1 / 60

A, B and C working togehter their rate will be added together =

A + B + C =  1 / 20 + 1 / 30 + 1 / 60 = 1 / 10

so they can work together to finish same piece of work in 10 days

Solve 4b +8= 6b - 4 b= ?​
AnnyKZ [126]

Answer:

B = 6

Step-by-step explanation:

1. 4b + 8 = 6b - 4

2. Add 4 to both sides: 4b + 12 = 6b

3. Subtract 4b from both sides: 12 = 2b

4. Divide 12 by 2: b = 6
