In a ratio of 7:3, for every 7 adults you have 3 children. So 30% of the total are children. I.e. if you have 10 people .7 times (10) are adults or 7 and .3 times (10) are children or 3. So for 370 people, .3 times 370 are children, or 111.
Watch videos on YouTube, that's what I do with geometry.
A = change in velocity divided by change in time
a = v/t
= 15 - 5 / 10 - 0 = 10 / 10 = 1 m/s^2
Answer:
H(n) = -n^2+4+n
g(n) = n-1
Find g(h(n))
Step-by-step explanation:
hello :
g(h(n)) = g(-n²+4+n) =(-n²+4+n)-1
g(h(n)) =-n²+n+3
Answer:
$500
Step-by-step explanation:
You hand him 100%
He pays back 140%(original amount plus 40%)= 700
Original amount =x
700/140 = x/100
140x=700*100
140x = 70,000
x=500
200 is the 40% of 500
500+200= 700
