Answer:

\quad y=-\frac{24-3x}{8}

Step-by-step explanation:

1. Subtract 3x from both sides

3x-8y-3x=24-3x

2. Simplify

-8y=24-3x

3. Divide both sides by -8

\frac{-8y}{-8}=\frac{24}{-8}-\frac{3x}{-8}

4. Simply again to get answer.

If U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }. A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 } .Find
Zina [86]

Answer:

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = {2, 4}

Step-by-step explanation:

Given the set :

U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }

A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 }

(A - B) = elements of A which are not in B

(A - B) = {1, 3}

(A - B)' = the complement of A - B ; element in the universal set which are not in A - B

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = elements in both set A and set B

(A n B) = {2, 4}

At a campground, a rectangular fire pit is 7 feet by 6 feet. What is the area of the largest circular fire that can be made in t
Fittoniya [83]

The area of the circular fire pit is 4096 square inches.

Explanation:

Given that the rectangular fire pit is 7 feet by 6 feet.

We need to determine the area of the largest circular fire that can be made in this fire pit.

The diameter of the circular fire is 6 feet

The radius is given by

r=\frac{6}{2} =3

Radius is 3 feet.

The area of the largest circular fire pit can be determined using the formula,

Area=\pi r^2

Substituting the values in the formula, we have,

Area = (3.14)(3)^2

        =(3.14)(9)

Area= 28.26 \ ft^2

We need to convert feet to inches by multiplying by 12, we get,

Area = 28.26\times (12)^2

Area = 4096.44 \ in^2

Rounding off to the nearest square inch, we get,

Area= 4096 \ in^2

Thus, the area of the circular fire pit is 4096 square inches.
