Answer:
$45 (corrected answer)
Step-by-step explanation:
Given
Gavin : Jim = 1 : 3
fraction that Gavin gets = 1 / (1+3) = 1/4
fraction that Jim gets = 3 / (1+3) = 3/4
given that Gavin gets $15,
Gavin's share = (1/4) ----> equivalent to $15
Jim's share = (3/4) ----> equivalent to $15 x 3 = $45
Answer:
D. 80%
Step-by-step explanation:
It's easier to see it as 80/100 or 8/10
hopefully this helped :3
Answer:
2π
Step-by-step explanation:
This is a little something you have to memorize, but you could derive it from the equation pb = 2π. In the parent function, the b value is 1, so the period, p, is equal to 2π/1 or just 2π.
3/7 for sure hope this helps
The equation is
time= distance/rate
and the train is going 300 miles
the car is going 200 miles
the train goes 20 miles faster than the car
fitting the numbers into the equation
200/r=300/(r+20)
cross multiply
200/r = 300/(r+20)
200(r+20) = 300r
distributive property
4000+200r=300r
subtract 200r from both sides to add like terms
4000=100r
divide 100 from each side to get r by itself
40 = rate of car
60 = rate of train
