Answer:

5 9/20

Step-by-step explanation:

4 7/10 + 6/8

Simplify the fractions by dividing the second top and bottom  by 2

4 7/10 + 3/4

Getting a common denominator of 20

4 7/10 *2/2  + 3/4 * 5/5

4 14/20  + 15/20

4 29/20

4 + 20/20 + 9/20

4+1+9/20

5 9/20

First, you have to find the common denominator.

It is 40.

But if we change the denominator, you have to change the numerator as well.

We multiplied 10 by 4 to get to 40, so we multiply 7 by 4.

\frac{28}{40}

We multiplied 8 by 5 to get to 40, so we do the same to 6:

\frac{30}{40}

Now add them:

\frac{28}{40} +\frac{30}{40}

We get:

58/40

1+18/40 is my answer...

A farmer is going to divide her 30 acre farm between two crops. Seed for corn costs $15 per acre. Seed for wheat costs $30 per a
Deffense [45]

Answer:

$3200

Step-by-step explanation:

The total area of land is 30 acre. Let x represent the area in acre that corn is planted and y represent the area in acre that wheat is planted. Therefore:

x + y = 30               (1)

Also, the farmer can spend at most $750 on seeds. Corn cost $15 per acre, maize cost $30 per acre. Hence:

15x + 30y ≤ 750      (2)

Also, x and y > 0

The profit is given by the function:

Profit = 100x + 110y

Graphing equation 1 and equation 2 and solving, we get the points:

(10, 20)

Hence the maximum profit is at:

Max profit = 100(10) + 110(20) = $3200
