Answer:
336 and 448
Step-by-step explanation:
sum the ratio
divide the actual number by the sum i.e 784÷7=122
multiply 112 by 3 and by 4
If you plug in the # the only one that is correct is y-8=-0.2(x+10)
Answer:
t = In2/ r
Step-by-step explanation:
Given the formula : A = Pe^rt
For investment to double ;
Final amount (A) = 2 * initial investment (p)
A = 2p
Hence,
2p = pe^rt
2 = e^rt
Take the In of both sides
In2 = rt
Divide both sides by r
In2 /r = rt /r
In2/ r = t
t = In2/ r ; Hence, the proof
Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:
1000 meters / 200 meters = 5 times in around the track for ONE kilometer.
To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:
5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.
