A room has an area of 121 ft2 but carpeting is only sold in m2. How much carpeting is needed to carpet the room?A.) 12.1 m2
B.)18.76 m2
C.)101.17 m2
D.)11.24 m2

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "D.)11.24 m2."
First, we need to know the conversion between feet to meters.
1 meter = 3.28 feet
1 meter^2 = 10.7584 ft^2

Given the value of 121 ft^2,
= 121 ft^2 * (1 m^2 / 10.7584 ft^2)
= 11.2470 m^2

Answer 2

Answer:

The correct answer is D. 11.24 m2

If the perimeter of a right triangle is 42 units and the length of the hypotenuse is 20 units, find the length of the other two sides of the triangle.Can you please show work

Answers

so
a^2+b^2=c^2
c=hypotenuse
a^2+b^2=20^2=400

if the permiter is 42 then
p=hypotonuse+side+side
42=20+side+side
subtract 20 from both sides
22=side+side

a+b=22
subtract b from both sides
a=22-b
subsitute for a in equation below
a+2+b^2=c^2
(22-b)^2+b^2=400
b^2-44x+484+b^2=400
2b^2-44x+484=400
divide both sides by 2
b^2-22x+242=200
subtract 200 from both sides
b^2-22x+42=0

it's hard to find the number, but the numbers are -19.8882 and -2.11181
(b-19.8882)(b-2.11181)=0
if xy=0 then assume that x and y=0

b-19.8882=0
add 19.8882 to both sides
b=19.8882

b-2.11181=0
add 2.11181 to both sides
b=2.11181

the side legnths are 19.8882 units and 2.11181 units

Hello,

Simplify 1/4(4f-8) using the distributive property

Answers

1/ 4 ( 4 f - 8 ) =

1 x ( 4 f - 8 ) / 4 =

1 x 4 f - 8/ 4 =

= 4 f - 8 / 4

Factor out common term 4 :

= 4(f-2) 4

Divide the numbers : 4 / 4 => 1

Therefore:

= f - 2

hope this helps!

Final answer:

By applying the distributive property to the expression 1/4(4f-8), we get the simplified form of the expression as f - 2.

Explanation:

To simplify the expression using the distributive property, you need to multiply the term outside the parenthesis by each term inside the parenthesis. In this case, the term outside the parenthesis is 1/4. So, you would multiply 1/4 by 4f and 1/4 by -8. Doing this gives you:

1/4 * 4f = f

1/4 * -8 = -2

Therefore, 1/4(4f-8) simplifies to f - 2.

The question asks us to simplify the mathematical expression 1/4(4f-8) using the distributive property. To use the distribitive property, you distribute or multiply the 1/4 to each term within the parenthesis.

So, 1/4 * 4f is equal to f, while 1/4 * -8 is equal to -2. Therefore, the simplified form of 1/4(4f-8) becomes f - 2.

A circle is defined by the equation x2 + y2 + 8x + 22y + 37 = 0. What are the coordinates for the center of the circle and the length of the radius?

Answers

The center of the circle is: (-4 ; -11) and the radius of the circle is r = 10

What is equation of circle?

The general equation for a circle is (x-a)² + (y-b)² = r², where ( a, b ) is the center and r is the radius.

Given:

x² + y² + 8x + 22y + 37 = 0.

Now, to find both coordinates and radius write the given equation in standard form:

(x-a)² + (y-b)² = r²

x² + 8x + y²+ 22y= -37

( x² + 2* x*4 + 4²)+( y² + 2*y* 11 + 11²) = -37 + 16 + 121

(x + 4)² + ( y+ 11)² = 100

(x + 4)² + ( y+ 11)² = 10²

So, center of the circle is: (-4 ; -11)

and the radius of the circle is r = 10

We can say that:
8x = -2ax
8 = -2a
a = -4

22y = - 2by
22 = -2b
b = -11

37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10

With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10

P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0
