6. You have 220 feet of fencing material to enclose a rectangular area for your pet animals. Let x = the length of the rectangular enclosure. (a) [7 points] Set up the function A(x) that represent the enclosed area. (b) [7 points] What should be the dimensions of the enclosed area? (c) [2 points] What is the maximum area of the enclosed area?

Answers

Answer:

I will start with (c)

(c) What is the maximum area of the enclosed area?

the maximum area of a rectangle is always given by a square figure

since the square has 4 equal sides, each side will be 220 / 4 = 55 ft long

maximum area = 55 x 55 = 3,025 ft²

(b) What should be the dimensions of the enclosed area?

the dimensions would be 55 ft in length by 55 ft in width

(a) Set up the function A(x) that represent the enclosed area.

perimeter of the rectangle = 220

we have 4 equal sides, so

A(x) = x²

For Spirit Day, each 8th-grade homeroom designs a unique twocolor T-shirt. They get to choose from the colors red (R), blue (B), green (G), violet (V), and orange (O). Each T-shirt is a solid color with a different color used for the student's name. What is the probability that a homeroom will have a T-shirt with a combination of blue and violet?

Answers

Answer:

P(B and V)=10%

Step-by-step explanation:To solve this poroblema we use the formula of combinations:

C(n,r)=(nr)=n!(r!(n−r)!)

Where n is the number of objects that can be chosen and you choose r from them.

There are 5 colors of shirts.

The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:

5C2= [tex]\frac{5!}{2!(5-2)!}[/tex]

5C2=10

The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

2C2=1

Then the probability is:

P( B and V)= [tex]\frac{1}{10}[/tex]

=0.1= 10%

[tex]\frac{2C2}{5C2}[/tex]

Answer:

P( B and V)=10%

what is 3.78 plus 8.94

Answers

The answer is 12.72 hope this helps

Step-by-step explanation:

You'll add them it's just like simple addition but you just have to know where the decimal point will be after adding

3.78

+8.94

12.72

When you are adding you start from the back with back I mean the end so when you add 8 plus 4 it's going to be 12 then you write or type the 2 and then carry the 1 and add it to the 7 which is going to be 8 then you add the 8 to the 9 which is going to be 17 that's why we have the 7 there then you carry 1 and add it to the 3 which is going to be 4 and then 4+8 is going to be;12

That's how we got the 12.72

Answer:

All of them demonstrate the distributive property, except for number 4. 1-3 all have a number on the outside of the parenthesis to distribute itself to the number and variable within the parenthesis, while #4 has a plus sign outside each pair of parenthesis, making you unable to distribute those numbers.

How do I workout/find the unknown angles please

Answers

Answer: x = 135 degrees and y = 225 degrees.

Step-by-step explanation: To solve this problem we first use the equation (n-2)*180 [n being the number of sides] to find the sum of interior angles in the figure. We plug the values in: (8-2)*180 = 6*180 degrees = 1080 degrees. We divide this by 8 to get the measure of an interior angle: 1080 degrees/8 = 135 degrees. Since all the interior angles of a regular polygon are congruent, we can say that angle x + angle y = 360 degrees. Thus subtract x degrees from 360 degrees to get y: 360 degrees - 135 degrees = 225 degrees. Therefore, x = 135 degrees and y = 225 degrees.
