An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded

dsp73

Answer:

B - 12,111

C - 11,589

Step-by-step explanation:

Here are the options

A - 10, 999

B - 12,111

C - 11,589

In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit

Rounding off 10,999 to the nearest thousand is 11,000

the hundred figure is greater than 5, so one is added to the thousand figure. The

Rounding off 12,111 to the nearest thousand is 12,000

the hundred figure is less than 5, so zero is added to the thousand figure.

Rounding off 11,589 to the nearest thousand is 12,000

the hundred figure is equal to 5, so one is added to the thousand figure.

if a motercycle is moving at a constant speed down the highway of 40 km/hr, how long would it the motorcycle to travel 10 km

ahrayia [7]

Answer:

15 minutes

Step-by-step explanation:

First, the motorcycle goes at a speed of 40 km/hr.

The question asks for how long it would take to travel 10 km.

Well, there are 60 minutes in an hour, since we will be translating into minutes.

Also, 10 km is 1/4 of 40 km, so it would make sense that the time length would be 1/4 of an hour as well.

1/4 of 60 minutes is 15 minutes. So it takes 15 minutes for the motorcycle to travel 10 km.

Now, if all this wordy stuff is too much to comprehend, you can also solve using proportional relationships.

$\frac{40km}{60min}=\frac{10km}{xmin}$

Now cross multiply:

$40km*xmin=10km*60min\\40x=600$

Divide both sides by 40:

$\frac{40x}{40}=\frac{600}{40}\\x=15$

Again, this shows that it wouls take 15 minutes for the motorcycle to travel 10 km.
