Answer:
child's is $14
adult is $23
Step-by-step explanation:
3c + 1a = 65
3c + 3a = 111
a = 65-3c
3c + 3(65-3c) = 111
3c + 195 -9c = 111
-6c = -84
c = 14
3(14) + a = 65
42 + a = 65
a = 23
Answer:
If the ratio of one variable to the other is constant, then the two variables have a proportional relationship,
If x and y have a proportional relationship, the constant of proportionality is the ratio of y to x.
In this section, you will learn, how to find the constant of proportionality from a table which contains the values of x and y.
Step-by-step explanation:
I hope that helps, I'm so sorry if it doesn't
So to find the missing value when you have a number and a number is simple all you have to do is percent/ 100 = a/b then you multiply the two numbers across from each other and divide by the lonely number so 18/100=27/x so multiply 27x100=2700 then divide by 18 so 2700/18= 150 so x= 150 for the second one you do the same thing 36/100=45/y do 45x100=4500 then divide by 36 4500/36=125 so y=125 and to check you can always do 45/125 x100 and you should get the same percentage
Answer:
approx. 251 in³
Step-by-step explanation:
The appropriate formula to use here is V = πr²h. Substituting 2 in for r and 5 in for h, we get:
V = π(2 in)^2·(5 in), or
V = π(4 in²)(5 in) = 80π in³, or approx. 251 in³
