Answer: 84 inches
Step-by-step explanation: When we look at how many carrot seeds he plants every 3 inches we can see that he plants 5 every time. This is saying that every 3 inches he will place 5 carrot seeds. If he wants to plant 140 seeds, he will still be planting 5 seeds every 3 inches. This means that we need to multiply the 140 seeds by 3 inches and divide by 5 to get our answer. This is 420 / 5 which equals 84. I think that is how it is done I am very sure of it!()_()()-();)
Answer:
This problem is incomplete, we do not know the fraction of the students that have a dog and also have a cat. Suppose we write the problem as:
"In Mrs.Hu's classroom, 4/5 of the students have a dog as a pet. X of the students who have a dog as a pet also have cat as a pet. If there are 45 students in her class, how many have both a dog and a cat as pets?"
Where X must be a positive number smaller than one, now we can solve it:
we know that in the class we have 45 students, and 4/5 of those students have dogs, so the number of students that have a dog as a pet is:
N = 45*(4/5) = 36
And we know that X of those 36 students also have a cat, so the number of students that have a dog and a cat is:
M = 36*X
now, we do not have, suppose that the value of X is 1/2 ("1/2 of the students who have a dog also have a cat")
M = 36*(1/2) = 18
So you can replace the value of X in the equation and find the number of students that have a dog and a cat as pets.
