Answer: The mean is 3780
Step-by-step explanation:
Mean is found by adding all values and dividing the sum by how many values were added.
4250+4019+3895+3739+3401+3376=22680
22680/6=3780
One “x” tile and five “1” cubes
Answer: 1.=336m
2.=276.4ft
3.=889in
4.=2.58mi
5.= 4042mm
Step-by-step explanation:
Answer:
x= -9
Step-by-step explanation:
1. distribute
3(+1)=2(−3)
so it would look like this:
3+3=2x-6
2. subtract 3 from both sides
It would look like this:
3x=2x-9
3. subtract 2x from both sides
It would look like this:
x= -9
And that is your answer!!
Answer:
Step-by-step explanation:
What you are trying to do is a nice way to solve this problem. Without knowing any physics, you are using what math you know to get the answer. You are actually very close to being correct, and you are right. You do have to divide by 60.
Here's why and it is the one bit of physics you have to know.
The speed is km/hour. That word hour is the culprit. Your time is in minutes and you have to get it into hours. In physics, the units have to be consistent.
So ...
b1 = 19 minutes which is 19 min [1 hour / 60 minutes] = 19/60 = 0.31667 hour
b2 = 26 minutes which is 26 min [ 1 hour/60 minutes] = 26/60 = 0.4333 hour
h = 40 km/hour
Area = (0.31667 hour + 0.4333 hour)*40 km/hour /2
Area = 0.75 hour * 40 km/hr //2
Area = 15 km
