I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
Answer:
Step-by-step explanation:
You need to set up a ratio for the original recipe and then use that ratio for the new one.
If we need 3 cups of flour for every 4 cups of sugar, we have a 3 c flour/4 c sugar ratio, or 3/4
The new ratio is 9 c of flour for ? c of sugar. Those ratios have to be the same, so we set up an equation like this:
3/4 = 9/?
In order to keep the same ratio, you have to multiply by the same number. Since 3*3 = 9, multiply 4*3 to get your answer.
The answer to this would be 60 boxes of socks
Answer:
there are 10 triangles
Step-by-step explanation:
Answer:
4 - 2.7
Step-by-step explanation:
Since the answer we want is 2.7 less than 4, you subtract 2.7 from 4 to get it.
If it was 2.7 is less than 4, you could make an inequality: 2.7<4
The less than sign works both ways, saying that 2.7 is less than 4 and that 4 is greater than 2.7.
I hope this helps :)
