Answer:

Step-by-step explanation:

In 60 minutes, minute hand completes 360

i.e., one rotation.

⇒ in 1 minute, minute hands completes

360

∘

Hence, in 5 minutes the angle covered is is 6×5=30

The angle of sector formed is 30

The area swept by the minute hand in 5 minutes=

360

×π×14×14

Using π=

, we get

The area swept by the minute hand in 5 minutes =

154

sq. cm

I do not know what to put and this was due yesterday

atroni [7]

Answer:

Your answer will be x=2

Step-by-step explanation:

Five plus 6 times a number is equal to 21 minus 2 times the number

Your equation is this:

5+6x=21-2x

Subtract 6x from both sides

5+6x-6x=21-2x-6x

5=21-8x

subtract 21 on both sides

5-21=21-21-8x

-16=-8x Divide -8 on both sides

2=x

Hope this helps :)

The radius of a circle is 6. Using T, which equation expresses the ratio of the circumference of the circle to the circle's diam

Liono4ka [1.6K]

Answer:

Option (B)

Step-by-step explanation:

The given question is incomplete; here is the complete question.

The radius of a circle is 6. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?

A) C/6 = π

B) C/12= π

C) C = 6πr

D) C = 12πr

Formula to get the circumference of the circle is,

C = 2πr = π × D

Where C = circumference of the circle

D = Diameter of the circle

By dividing with D on both the sides of the formula,

$\frac{\text{C}}{\text{D}}=\pi$

Since, diameter 'D' = 2r,

$\frac{\text{C}}{\text{2r}}=\pi$

$\frac{\text{C}}{2\times 6}=\pi$

$\frac{\text{C}}{12}=\pi$

Therefore, equation given in Option (B) will be the correct expression.

How can you represent and summarize data in a dot plot?

krek1111 [17]

In a dot plot, each one of the dots represents a value in the data set. When there are multiple values at a particular number, the dots just get stacked on top of each other. Using the dots in the plot, you can find the mean, median, mode or any other statistic that you need to summarize the data.
