Approximately how many square feet of the turf need to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth.

15.7 square feet
19.6 square feet
42.8 square feet
78.6 square feet

Answers

Answer:

  (b)  19.6 square feet

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

If the diameter is 5 feet, the radius is 2.5 feet, so the area is ...

  A = (3.14)(2.5 ft)² ≈ 19.625 ft² ≈ 19.6 ft²

The area of a base circle is about 19.6 square feet.

The length of a bedroom in a blueprint is 5in. and the width is 7in. The actual length of the bedroom is 12ft. Identify the actual width of the bedroom in feet.

Answers

To solve this problem, we can use cross multiplication:

First, we can to convert inches into feet so...

5 inches = 0.416667 ft

7 inches = 0.583333 ft

(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)

x = 16.8 ft

So the actual width is 16.8 ft.

If CS = 4 and AD = 10, what is the measure of CD? Round to the nearest hundredth. Show all your work.

Answers

The measure of the length of line segment CD is; 12.8

Pythagoras theorem

Pythagoras theorem States that the square of the hypotenus of a triangle is equal to the sum of the square of the opposite and square of the adjacent side.

From the task content, the center of the circle is at point S and since CS = 4;

It follows that CA = 4× 2 = 8.

Hence, it follows from Pythagoras theorem that;

CD = √(8² + 10²)

CD = √64+100

CD = √164.

CD = 12.8

I'm struggling with this question on quadratic equations and would like somebody to explain it to me. Thank you!

Hello, sorry for taking half an hour to respond.

a) If x represents the number of students in her class, we have :

The cost of a calculator on website C : 480 : x
The cost of a calculator on website D : 480 : (x+4)

b) We call the price of a calculator on website C as a, and the price on website D is a-6
Let's also call the amount of calculators if we buy on website C as d, and the amount of calculators if we buy on website D as d + 4

We have :

a.d = (a-6)(d+4)
Break the brackets out : ad = ad-6d + 4a - 24
=> -6d + 4a - 24 = 0
Divide both sides by 2
=> -3d + 2a - 12 = 0

=> 2a = 3d + 12

So, d is divisible by 3, and a is divisible by 2 => ad is divisible by 6.

And ad x the amount of students = 480

So, we can conclude that the amount of students is a factor of 80

Let's list out all of them : 1,2,4,5,8,10,16,20,40,80.

If there was 20 students :

The price of each calculator would be : 480 : 20 = 24

If it's 6 cheaper, it would be 24-6 = 18

And she would've gotten 480 : 18 (not divisible)

If you keep replacing like that, you'll eventually get the answer. I don't have time left, so the answer is 16 students. Hope it helps.

Two people worked on a car. The first person charged $ 85 per hour, and the second person charged $ 120 per hour. The people worked for a combined total of 15 hours, and together they charged a total of $ 1450. How long did each person work?.

Answers

The number of hours the first person worked on the car is 5, while the number of hours for which the second person working on the car is 10.

What is an equation?

An equation is formed when two equal expressions are equated so that the value of a variable can be found.

Let the number of hours for which the first person worked on the car is x

In order to solve the problem, we will make two equations. Now, since we know that the total number of hours for which the two-person worked on the car is 15, therefore, we can write it as,

[tex]x+y =15[/tex]

The amount charged by the first person is $85 per hour, while the amount charged by the second person is $120, and the total cost of the two is $1450 combined. therefore, the total cost can be written as

[tex]85x+120y = 1450[/tex]

As we got the two-equation solving the two-equation, to get our answer.

In the first equation, we will isolate y, in order to get the value of y in terms of x,

[tex]x+y = 15\\y = 15-x[/tex]

As we got the value of y, substitute the value in the second equation,

[tex]85x+120(15-x) = 1450\\85x+1800 - 15x = 1450\\70x = 350\\x = 5[/tex]

As we have the value of x, substitute the value in the first equation,

[tex]x+y=15\\(5)+y=15\\y=10[/tex]

Hence, the number of hours the first person worked on the car is 5, while the number of hours for which the second person working on the car is 10.

How to solve the quadratic equation?

Here we have the equation:

To solve this, first, we add x^2 on both sides:

12 = x^2

Now we can just apply the square root on both sides, to get:

±√12 = x

±3.46
