Answer: The answer is B.

Step-by-step explanation:

To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:

3 * 2 = 6

6 + 1 = 7 or 7/2

Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.

Our original equation is 7/2 /(divided by) 3/2 = ?

1. Keep the first fraction

7/2 / 3/2 = 7/2 / 32

2. Change the sign to its inverse operation

7/2 / 3/2 = 7/2 * 3/2

3. Flip the second fraction

7/2 * 3/2 = 7/2 * 2/3

Now, solve.

7/2 * 2/3

7 * 2 / 2 * 3 = 14/6

To make this a proper mixed number, first simplify.

14/6 / 2 = 7/3

Now, figure out how many wholes are in 7/3.

7/3 / 3 = 2 1/3

This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.

Therefore, the answer is 7/3 OR 2 1/3 OR B

R * p = -37.8 but also r + p = 13.5 what would r be? what would p be?

Nana76 [90]

R * p = -37.8

Solve for either R or p.

R = -37.8/p

Now plug into R + p = 13.5

-37.8/p + p = 13.5

Solve for p.

After finding p, plug your p-value into either R + p or R*p to find R.

Take it from here.

W=3? What is the value of the expression below when w = 5w+ 2

topjm [15]

Answer:

The value of the expression at w=3 is;

$17$

Explanation:

Given the expression;

$5w+2$

Then when w=3, the value of the expression is;

$\begin{gathered} 5w+2 \\ =5(3)+2 \\ =15+2 \\ =17 \end{gathered}$

The value is gotten by replacing/substituting w with 3 in the expression;

Therefore, the value of the expression at w=3 is;

$17$

The back of jake's property is a creek. Jake would like to enclose a rectangular area, using the creek as one side and fencing f

kow [346]

Answer:

The maximum possible area of the pasture is 26,450 feet square.

Step-by-step explanation:

Let us assume the width of the rectangular area = m ft

and the length of the area = k ft

Also assume: ( one side with k units IS NOT FENCED)

So, the total perimeter of the fencing is:

2 m + k = 460

or, k = 460 - 2m ........ (1)

Now, AREA OF THE RECTANGULAR PORTION = Length x Width = k x m

Put k = 460 - 2m

We get: A = m (460 - 2m)

or, A = 460 m - 2m²

We need to find the maximum for the parabolic function A = 460 m - 2m²

The function has a maximum value as the quotient in front of x^2 is negative: -2 < 0

A (max) = $c-\frac{b^2}{4a}$ where a = -2, b = 460, c = 0

= $-\frac{(460)^2}{4(-2)} = 26,450$

A max = 26,450 sq ft.

The maximum possible area of the pasture is 26,450 feet square.
