To make a mixed number an improper fraction, multiply the whole number by the denominator and add the product to the numerator. The denominator remains the same. In this case, 4 is multiplied by 7 to become 28, and plus 2 is 30. Therefore it is 30/7.

If "4/2/7" is all we have to work with, then PEMDAS rules will save the day. Do the division from left to right.

4/2 becomes 2. Then we have 2/7, a proper fraction. I don't see where an improper fraction would come from in this case.

Answer:

1/2

2/4 is equal to 1/2, because if you divide 4 by 2 you get 2, and if you divide 2 by 2 you get one.

Patty made a banner that has an area of 36 square inches,. The length and width of the banner are whole numbers. The length is 4

omeli [17]

Answer: width= 3 inches; length= 12 inches.

Step-by-step explanation:

From the question, the length is 4 times greater than the width.

Let the width of the banner be represented by y.

Since the length is 4 times greater than the width. It will be denoted as:

Length= 4 × y = 4y

Since area= length×width

4y × y = 36

4y^2 = 36

Divide both side by 4

y^2 = 36/4

y^2 = 9

We have to find the square root of 9

y= √9

y = 3

The width is 3 inches.

The length will be: (3×4) = 12 units.

At a time denoted as t=0, a student carrying a new flu virus comes back to an isolated campus that has a fixed number of 1000 pe

Varvara68 [4.7K]

Answer:

$\dfrac{dx(t)}{dt} = kx(t)[1000-x(t)],$ x(0)=0$

Step-by-step explanation:

Total Number of People on Campus =1000

Let the number of people who have contracted the flu =x(t)

Therefore, the number of people who have not contracted the flu =1000-x(t)

Since the rate at which the disease spreads is proportional to the number of interactions between the people who have the flu and the number of people who have not yet been exposed to it.

$\dfrac{dx(t)}{dt} \propto x(t)[1000-x(t)]$
