Say you have the number:
3,347
You can round it to the nearest thousand by figuring out whether 347 turns out to be closer to 0 or 1,000. If it's closer to 0, you round to the nearest thousand by producing the result 3,000. Since 347 is closer to 0, it would be incorrect to round the number 3,347 to the nearest thousand by producing the result 4,000.
In this case you round to the nearest thousand by producing the result 3,000.
The first part cannot be answered here without the diagram. However, I can tell you that the model he's building is 1/10 the size of the actual car. That means every measurement on the car is divided by 10 to get the model measurement.
The radius of the car wheel is 27 inches, so the diameter is 54 inches. Using what we know about the model, the correct proportions for the model wheel diameters would be 54 / 10, or 5.4, inches. Therefore, wheels with a diameter of 6 inches would not be in proportion with the model.
Answer:
40 yards
Step-by-step explanation:
Data:
The hyperbola equation is expressed as follows:

Dividing each term by 250 000 gives:


thus:
a² = 40
Therefore, the houses will be 20 yards apart.
