Answer : 2.5
Step - by - step explanation :
X / Y = COP
5 / 2 = 2.5 or 2 1/2
Y = 2.5x
5 gallons x gallons
------------- = ----------------
12 hours 240 hours
using cross products
5 * 240 = 12 * x
1200 = 12 x
divide each side by 12
1200/12 = 12x/12
100 =x
You will need 100 gallons
it hasn't been specified which ticket the question's is asking but I'm guessing the price of the adult ones so $30.00
altogether that's two adults and 3 children who all paid a total of $105.00
let's simplify that to algebra
children tickets = c adults tickets = a
3c + 2a = $105.00
we know that 1c is 0.5a because each child ticket is half of an adults one <em>as stated in the question</em>
so in terms of (adults) a: half of 3 meaning 3×0.5= $1.5 meaning 1.5a
so now <em>3c = 1.5a</em>
so we can substitute and have like terms
meaning 1.5a + 2a= $105
3.5a =$105.00
divide by 3.5 on both sides to get a by itself thus the value of a:
a = $30
so each adult tickets cost $30
You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.
Therefore, 9/10 is larger.
Answer:No it is not proportional
Step-by-step explanation:
4 hours=$37
7 hours=$64.75
I t is not proportional because if 4 hours =$37 then 6 hours is supposed to be around $70 but 7 hours=$64.75
