Find the circumference in feet.

Answer:

1 - 2/3 = 1/3

Step-by-step explanation:

1            3         3                         2            1                 2

-      x     -     =    -            -             -      x     -         =      -

1            3         3                         3            1                 3

3/3 - 2/3 = 1/3

Answer:

x=28

Step-by-step explanation:

4(x-5)=92

4x-20=92

add 20 to both sides

4x=112

divide 4 on both sides

x=28

Answer:

The value of x is 28

Step-by-step explanation:

4(x - 5) = 92

4x - 20 = 92

4x = 92 + 20

4x = 112

x = 112 ÷ 4

x = 28

Thus, The value of x is 28

Answer:

1. D. Teorema.

2. A. Axioma.

Step-by-step explanation:

En matemáticas, un conjunto de proposiciones que deben estar respaldadas por una prueba adecuada basada en el razonamiento se denomina teorema. Se puede demostrar plenamente que todos los teoremas matemáticos son verdaderos mediante el razonamiento.

Sin embargo, un axión es evidente por sí mismo y no necesita ser probado. Es un hecho ya establecido.

Answer:

1. D. Teorema.

2. A. Axioma.

Answer:

1.870828693387

Step-by-step explanation:

Standard Deviation, σ: 1.870828693387

Count, N:4

Sum, Σx: 12

Mean, μ: 3

Variance, σ2:  3.5

Steps

σ2 = Σ(xi - μ)2

N  =   (6 - 3)2 + ... + (1 - 3)2

4 = 14

4  = 3.5

σ = √3.5

= 1.870828693387

Answer:

8 o B

Step-by-step explanation:

14b = 112

112/14 = 8

B = 8

Puedes verificar la respuesta multiplicando 8 a 14 y obtendrás el número 112 como la respuesta. Eso significa que la respuesta es verdadera.

Answer:

E. 54cm ^2

Step-by-step explanation:

when finding the area just multiply length over width .for example 9 is the length times it to the width 6 you get 54 so the area will be 54 cm

Answer:

E

Step-by-step explanation:

length times width

6 x 9 = 54

Answer:

C)

Step-by-step explanation:

Answer:

377 feet

Step-by-step explanation:

Find the circumference on the circle, using the formula C = 2[tex]\pi[/tex]r

Plug in 12 as r, the radius, then solve:

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](12)

C = 24[tex]\pi[/tex]

Multiply this by 5, since the kids ran around it 5 times:

24[tex]\pi[/tex](5)

= 120[tex]\pi[/tex]

To the nearest foot, this is 377.

So, the kids ran round 377 feet

Answer:

[tex]y=-x+10[/tex]

Step-by-step explanation:

Hi there!

Slope intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (2,8),and (8,2)

​[tex]m=\frac{2-8}{8-2}\\m=\frac{-6}{6}\\m=-1[/tex]

Therefore, the slope of the line is -1. Plug this into  [tex]y=mx+b[/tex]:

[tex]y=-x+b[/tex]

2) Find the y-intercept (b)

[tex]y=-x+b[/tex]

Plug in a given point and solve for b

[tex]8=-2+b[/tex]

Add 2 to both sides

[tex]8+2=-2+b+2\\10=b[/tex]

Therefore, the y-intercept is 10. Plug this back into [tex]y=-x+b[/tex]:

[tex]y=-x+10[/tex]

I hope this helps!

Answer:

7 nights

Step-by-step explanation:

So total pages = 225

he has read = 120

pages left to reas = 225-120

= 105

so

15 pages = 1 night

1 page = 1/15 night

105 pages = 1/15×105

= 7 nights

There, Bryan will read 7 nights until he finishes the book

Answer:27

Step-by-step explanation:

Answer:

Hello There!!

Step-by-step explanation:

Find out 10% first which is 10.

20% will equal 20.

half of 10%=5% is 5.

There is 2% left.To find out 1% divide 100 by 100 which 1 so 2% is 2.

Add 20(20%)+5(5%)+2(2%)=27 which equals 27%.

hope this helps,have a great day!!

Answer:

The polar bear weighs 525kg

Step-by-step explanation:

C = Polar Bear

D = Baby Elephant

____________________________

(1)  C + D = 700 kg

(2)  C = 3D

________________________________

C = 700 - D

700 - D = 3D

700 = 4D

________________________________

525 + 175 = 700

Then we get our answer, the polar bear weighs 525kg, and the baby elephant weighs 175kg.

Hope this helps you :)
