Two composite numbers that have 8 as a factor are 16 and 24.
Answer:
<em>12 scoops of dog food are needed for 6 dogs,</em>
Step-by-step explanation:
<u>Proportions</u>
The number of scoops of dog foods and the number of dogs are proportional variables.
We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.
We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.
Thus, the constant of proportionality is 2.
For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.
12 scoops of dog food are needed for 6 dogs,
The answer is 110 adult tickets. Let x= student tickets and y= adult tickets.
We know that the total tickets sold was 440. That means the total number of student tickets (x) plus the total number of adult tickets (y) equaled 440. Putting it into an equation, you get:
x+y=440
Now we know that the amount of student tickets is equal to three times as many adult tickets, so in an equation that is seen as:
x=3y
In order to solve for one variable, plug in 3y for the x value of the first equation to get:
y+3y=440
then solve:
4y=440
y= 440/4
y=110
The total number of adult tickets sold was 110 tickets.
(This method used in math is technically called "Solving Systems of Equations", just fyi).
You just keep subtracting 3 yo the previous number, so day one would be $82 and day three would be $79...etc. Day five would be $70 so sweet
