➪ Thus, The carpet takes up 1/2 unit² area of the classroom...~

Answer:

1/2 or half of the classroom area

Step-by-step explanation:

Step 1: Calculating area of carpet

Let total length be l and width be w.

Now, according to the problem,

Area = 2l/3 x 3w/4

= 2lw/4

Step 2: Take area of carpet and area of classroom as a ratio

(2lw/4) / lw

= 2/4

= 1/2

Therefore, the carpet takes up 1/2 or half of the classroom area.

Answer:

17 feet

Step-by-step explanation:

add up all the sides. 3.5+3.5+5+5=17

Answer:

A = 17.5

P = 17

Step-by-step explanation:

A = (b)(h)  length and width is same as base and height

A = 3.5(5)

A = 17.5

P = 2(3.5) + 2(5)

P = 7 + 10

P = 17

Answer:

Step-by-step explanation:

1. Simplify the expression

8 1/2= 81/2

81/2 * 11

Multiply the fractions:

81/2 * 11

basically (81 * 11)

which turns into 891/2

Then you simplify from there!

Answer:

2x - 2y = 14

x - y = 2

1.) x = 2+ y

2.) 2(2+ y) - 2y = 14

3.) 4 + 4y - 2y = 14

4.) 4y - 2y = 14 - 4

5.) 2y = 10

6.) 2y/2 = 10/2

7.) y = 5

x - y = 2

8.) x - 5 = 2

9.) x = 2 + 5

10.) x = 7

Therefore, x = 7 and y = 5

Step-by-step explanation:

1. First make one of the variables in any equation the subject of the formula

2. Then substitute the variables equating to the subject of the formula

3. Group the like terms,then solve the equation.

4. Replace the value you will find in the first equation into the other equation.

5. Repeat with the same

Answer:

[tex]x=17.3[/tex]

Step-by-step explanation:

Given the following question:

[tex]x+23.4=40.7[/tex]

To solve, we need to understand that this is a simple one-step equation and all we have to do to find the answer is subtract 23.4 on both sides.

[tex]x+23.4=40.7[/tex]
[tex]23.4-23.4=0[/tex]
[tex]40.7-23.4=17.3[/tex]
[tex]x=17.3[/tex]

Hope this helps.

Step-by-step explanation:

area of a circle

A = pi × r²

circumference of a circle

C = 2 × pi × r

r = diameter / 2 (the radius is half of the diameter)

circle A

A = 63.585 = pi × 4.5² = pi × 20.25

pi = 63.585 / 20.25 = 3.14

C = 28.26 = 2 × pi × 4.5

pi = 28.26 / (2 × 4.5) = 28.26 / 9 = 3.14

circle B

A = 19.625 = pi × 2.5² = pi × 6.25

pi = 19.625 / 6.25 = 3.14

C = 15.7 = 2 × pi × 2.5

pi = 15.7 / (2 × 2.5) = 15.7 / 5 = 3.14

pi is always the same for every circle of any size. it is a natural constant defining the circumference and area of every circle in relation to the actual radius or diameter.

Answer: The value of g(2) is larger than the value of g(-4).

Step-by-step explanation:

Answer: The dimensions are that 2 sides are 5 inches and two are 10 inches.

Step-by-step explanation:

The are is 50 so the dimensions should equal 50 when you do height times width. So 5*10=50 and 5+5+10+10=30

Answer:

5 cubes by 4 cubes by 6 cubes

Step-by-step explanation:

Vp = 5/3 * 4/3 * 2 = 40/9 in^3.

Vc = (1/3)^3 = 1/27 in^3.

Vp/Vc = (40/9)/(1/27) = 40/9 * 27/1 = 120 Cubes.

The distance of sparky to the fire is 99.445 feet

Given the following parameters

The angle of depression = 6  degrees

If Sparky is looking over the fairly level, hence the hypotenuse is 100 foot

Required

Distance from spark tower to the fire

Using the expression below

Cos 6 = D/100

D = 100cos6

D = 100(0.9945)
D = 99.45foot

Hence the distance of sparky to the fire is 99.445 feet
