no. he isn't correct because the scale factor is an improper fraction. 2/5 means you have 2 out of 5, but if you have 8 out of 3, that means you have 2 3s and 2 more leftover. it wouldn't be a reduction, it'd be increasing!
Answer:
a) 9 meters.
b) The total change in temperature was of 288ºC
Step-by-step explanation:
Both these questions can be solved using rules of three.
a) 72 meters in 8 seconds. How many meters it changes each second(in 1 second)?
8s - 72m
1s - x m
9 meters.
b) In 1 hour, heated by 6ºC. How much in total during 48 hours?
1h - 6ºC
48h - xºC
x = 48*6
The total change in temperature was of 288ºC
Answer:
0.000086
Explantion :
Just move the decimal point 5 to the left.
my guess is you need to know what part d is worth, but you didn't ask a question so that is simply a guess.
If there are 11 points, then add to see how many are missing if there is only one part without a worth.
2+3+6=11.
Therefore, the teacher screwed up and you don't have to do part d because there is no value to it.
