How are the factors of 36 related to the factors of 72

1 answer:

8 0

They are related because some of the factors of 36 overlap with 72
EX: 36 - 1,2,3,4,6,12,18
EX: 72 - 1,2,3,4,6,12,18,31

So that means 1,2,3,4,6,12,18 overlap

If m(x)=x 5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Tatiana [17]

Answer:
m(x) has the same domain as (m*n)(x)

Explanation:
1- For m(x):
m(x) is a fraction. This means that the denominator cannot be zero, otherwise, the fraction would be undefined.
The denominator of m(x) would be zero at x = 1.
This means that the domain of m(x) can be any real number except 1

2- For n(x):
The value of x in n(x) can be any number. This is because there is no value that would make n(x) undefined.
This means that the domain of n(x) is all real numbers

3- For (m*n)(x):
(m*n)(x) = m(x) * n(x) = $\frac{x-5}{x-1} *(x-3) = \frac{(x-5)(x-3)}{(x-1)}$

We can note that the product is also a fraction. This means that the denominator cannot be zero.
The denominator here will be zero at x = 1.
This means that the domain of (m*n)(x) is all real numbers except 1.
This is the same as the domain of m(x)

Hope this helps :)

Julie and her friend went to the movies and bought one jumbo popcorn and two chocholate chip cookies for 5$. Marvin and his frie

makvit [3.9K]

Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.

Then, based upon the given info, 1j + 2c = $5.

Also, 3j + 5c = $14.50

Let's solve this system of equations using addition/subtraction:

Mult. the first equation by -3, to obtain -3j - 6c = -$15

Now add this result to the 2nd equation:

-3j - 6c = -$15
3j + 5c = $14.50
----------------------
-c = -$0.50, or c = $0.50. Since 3j + 5c = $14.50, subst. $0.50 for c
lets us find j:

3j + 5($0.50) = $14.50, so 3j = $12.00. Thus, j = $4.00.

Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.

A pound of weed and feed covers 200 square feet how many pounds are needed to fertilize a lawn measuring 70 feet by 50 feet

nika2105 [10]

You would have to find out how many square feet the lawn is first:
70 x 50 = 3500 square feet
You are told that one pound = 200 square feet so use this to calculate how many pound you’ll need for 3500 square feet.
3500 square feet divided by 200 square feet = 17.5 pounds
Answer: 17.5 pounds
