Um the answer is kinda hard to do cause the answer is 9.70e17, but i dont know how to do that in scientific notation.
Answer: 1
Step-by-step explanation:
1
8 seconds
The hardest part of this is setting up the equation -- the calculations are pretty easy.
You're told that the time (needed to go from 0 to 100 MPH) is inversely proportional to the horsepower: what this means is that as horsepower gets larger, time gets smaller. This makes sense since the more horsepower you have, the less time it will take you to get to 100 MPH
You can think of this as:
200 HP = 10 seconds
250 HP = x seconds
You set the equation up as:
250 HP / 200 HP = 10 sec / x sec
Now, just cross multiply and solve:
250 / 200 = 10 / x
250x = (200 x 10)
250x = 2000
x = 2000 / 250
x = 8
So, as you increase the horsepower from 200 to 250, the time decreases from 10 seconds to 8 seconds.
Hope this helps!
Good luck.
Answer:
After about 25 weeks, she will have $3000 left
Step-by-step explanation:
Emily won $3000000
She spends 4% weekly, which is
$3000000 × 4/100 = $3000000 × 0.04
= $120000
She spends $120000 Weekly
When she has $3000 left, she would have spent
$3000000 - $3000 = $2997000
Spending $120000 weekly, she will spend $2997000 in
(2997000/120000) weeks
= 24.975 weeks
i.e, she will have $3000 after approximately 25 weeks
