c) 10m

3.
a) 2km
b) 4km
c) 11km
d) 28km
Step-by-step explanation:
When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.
To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.
For example,
If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.
However, if we had 24.7 you would have to round it up because the 7 is from 5-9.
Hope this helps :)
The greatest common factor is 1 because there is not a number that goes into or will multiply and get 49 and 4. 49 is an odd number and 4 is an even number so the GCF is 1.
Answer:
Hours of television because it is the explanatory variable.
Step-by-step explanation:
For me, I am assuming the more time spent watching television would cause lower reading scores. I imagine this would be a bar graph, the vertical y-axis would be labeled the reading scores and the horizontal x-axis would be the amount of hours spent watching television. This is because when you graph, you move right then up to get to the unit, meaning the hours of television affect the reading scores. hope this helpss
