Joseph owns a dog that weighs 110 pounds. A bag of dog food recommends feeding a 40 pound dog 24 ounces of food per day. If x represents the amount of food needed to feed the larger dog, which proportion CANNOT be used to calculate how much food Joseph should feed his dog?

the proportion which CAN be used is 1760/x = 640/24   THEREFORE ANY OTHER PROPORTION CANNOT BE USED

Step-by-step explanation:

J's dog= 110lbs =1760 ounces

food recommendation on bag: 40lbs:24 ounces, therefore in ounces 760 ounces (dog weight): 24 ounces (food)

J's dog required amount,  110:x which in ounces is 1760 ounces : x ounces

so we get:

1760/x = 640/24  

 take cross products,

4224= 640x

x= 66 ounces

the proportion which CAN be used is 1760/x = 640/24   THEREFORE ANY OTHER PROPORTION CANNOT BE USED

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

the correct answer is x/3+10≥32

hope this !
