Pls solve and explain

4950 potholes in 6 weeks, estimated is 4800.

Step-by-step explanation:

To estimate, let's round 825 to the nearest 100th - 800.

Now we multiply 800 times 6 to find our estimate.

If we know that the road repair crew can fix 825 potholes PER WEEK, we can set up a proportion to find how many they can do in 6 weeks.

Let's cross multiply to find the value of x.

So the repair crew can fix 4950 potholes in 6 weeks.

4950 is pretty close to 4800, so our exact answer should be correct.

Hope this helped!

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
