Answer: This is a function, since it's considered to be able to be made into a word problem
Step-by-step explanation:
First let's solve for the rate, "b", by setting up a ratio with the two points given:
16.875/7.5=(ar^3)/(ar)
2.25=r^2
r=1.5
Now we need to solve for the initial value a using either point given...
7.5=a(1.5)^1
7.5=1.5a
a=5
So now we have solved for both variables and have a complete equation:
y=5(1.5)^x
I'd say Yana has 6...
30\ 6 is 5
the ratio range is a group inside 5..
so Dina has 30 swim suits...which is 5 times 6 of yana.
so since Dina has 24 "more" than yana... Dina is 4 : Yana is 1....4:1
Answer:
25 gallons of sulfuric acid
Step-by-step explanation:
Find how much sulfuric acid is in the tank by finding 50% of 50 (the total gallons of solution):
50(0.5)
= 25
So, there are 25 gallons of sulfuric acid.
No, because if x was 2:
5(2) + 3(2)= 10+6
=16
5(3) + 2y= 15 + 17y, it would already be to high of a number
