Find The Area Of Theregular Figure Below:A) 160.5 Km2B) 166.2 Km2C) 173.8 Km2D) 182.4 Km2E) 189.1 Km2explain

Answers

Answer 1

Answer:

Option C : 173.8 km² is the correct answer.

Step-by-step explanation:

Given that:

Side length = 6 kilometers

A shape with 8 sides is called an octagon, therefore, the given figure is an octagon.

Area of octagon is given by;

Area = [tex]2(1+\sqrt{2})a^2[/tex]

Putting a=6

Area = [tex]2(1+\sqrt{2})(6)^2[/tex]

Area = [tex](2+2\sqrt{2})(36)[/tex]

Area = 173.82

Rounding off to one decimal place

Area = 173.8 km²

Hence,

Option C : 173.8 km² is the correct answer.

Find f(5)

Answers

Answer:

f(5) = 2

Step-by-step explanation:

To evaluate f(5), that is when x = 5 in the interval x ≥ 5

then

f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so

f(5) = 2

Answer:

300 nickels

Step-by-step explanation:

Reading the question, someone has 435 nickels and dimes.

The total is $28.50.

You're trying to find how many nickels he has.

All you need to do is set up a system of equations.

I'm going to use x as the number of nickels and y as the number of dimes.

Based on the question, you can say that

x + y = 435

(the number of nickels and dimes have t equal 435)

and 0.05x + 0.1y = $28.50

(nickels are 5 cents and dimes are 10 cents)

You want to solve for x, the number of nickels.

You can manipulate the first equation by subtracting x on both sides.

After you do that, you will get y = 435 - x. Now, you can substitute this equation into the second one.

First, you can distribute the 0.1.

0.05x  + 0.1(435 - x) = 28.50

Then, you can put the two x's together.

0.05x + 43.5 -0.1x = 28.50

Next, you can subtract 43.5 on both sides to isolate x.

-0.05x + 43.5 = 28.50

Finally, you can divide on both sides to get x, which is the number of nickels.

-0.05x = - 15

x = 300 nickels

Andrew wants to run ten miles in three days .He ran 212 miles on Monday and 425 miles on Tuesday how many miles does Andrew need to run on Wednesday?

Answers

Answer: 3.63 miles

Step-by-step explanation: I think you meant to type 2.12 and 4.25 so I'm just going to go by that. To figure out how many more miles he needs to run, you add the amount he already ran together, and then subtract that from his goal. 4.25 plus 2.12 equals 6.37. 10 minus 6.37 equals 3.63. He needs to run 3.63 miles on Wednesday, in order to reach his goal of 10 miles.
