The number 2,874,992 how to round this number to the nearest 10,000

2,870,000

OK. Take a look at the number just to the right of the digit you want to round to. Since your number is 2,874,992 the digit in the 10,000th place is 7. The digit just to the right of that digit is 4. Now ask yourself... Is that digit less than 5? If it is, then replace that digit and all the other digits to the right with 0, so you get
2,870,000
as the properly rounded result.

Now let's make a minor change to show rounding up. If you were given the number 2,875,992 then instead of a 4, you would have 5 as the digit just to the right of the 7. And the answer to the question "Is that digit less than 5?" would be no. In which case you still replace that digit and all the others to the right with 0, but you'll also add 1 to the digit you're rounding, getting
2,880,000

But for this problem, the properly rounded result is 2,870,000

The answer is 2,875,000 because the 4(in the thousand) is closer to “5”

dale is driving to Miami. suppose that the distance (in miles) is a linear function of his total driving time (in minutes). dale
nexus9112 [7]
Considering there is a function (relationship) and that it is linear, the distance will change proportionally to time constantly. In other words, we are taking the speed to be constant throughout the journey.
If we let:
t = time (min's) driving
d = distance (miles) from destination
Then we can represent the above information as:
t = 40: d = 59
t = 52: d = 50
If we think of this as a graph, we can think of the x-axis representing time and the y-axis representing the distance to the destination. Being linear, the function will be a line, i.e. it will have a constant gradient. If you were plot the two points inferred from the information and connect the two dots, you will get a declining line (one with a negative gradient) representing the inversely proportional relationship or equally, the negative correlation between the time driving and the distance to the destination. The equation of this line will be the linear function that relates time and the distance to the destination. To find this linear function, we do as follows:

Find the gradient (m) of the line:
m = Δy/Δx
In this case, the x-values are t-values and our y-values are d-values, so:
Δy = Δd
= 50 - 59
= -9
Δx = Δt
= 52 - 40
= 12
m = -9/12 = -3/4
Note: m is equivalent to speed with units: d/t

Use formula to find function and rearrange to give it in the desired format:
y - y₁ = m(x - x₁)
d - 50 = -3/4(t - 52)
4d - 200 = -3t + 156
4d + 3t - 356 = 0

Let t = 70 to find d at the time:
4d + 3(70) - 356 = 0
4d + 210 - 356 = 0
4d - 146 = 0
4d = 146
d = 73/2 = 36.5 miles

So after 70 min's of driving, Dale will be 36.5 miles from his destination.
