Answer: 25.12 ft.

Step-by-step explanation:

Given: The diameter of circle d= 8 ft.

We know that the circumference of a circle is given by the formula:-

\text{Circumference}=\pi d\\\\\Rightarrow\text{Circumference}=(3.14)(8)\\\\\Rightarrow\text{Circumference}=25.12\ ft.

Hence, the exact circumference of a circle with diameter equal to 8 ft is 25.12 ft.

The circumference of the circle is the linear length of the circle if the arcs are laid linearly. In this case, the formula that must be followed is C = pi D where C is the circumference and D is the diameter. The circumference then is equal to 8 pi ft

Can anybody help me solve this ?

Answer:

77*

First we are going to take our given number, 25* and 78* and add them together.

25* + 78* = 103*

And subtract our answer, 103*, from 180*.

180* - 103* = 77*

77* is our missing angle. To prove it, we add angle measures a, b, and c, to make the number 180*

25* + 78* + 77* = 180*

Another way to write it is . . .

180* - (A + B) = C

~Hope this helps~

Select the correct answer from each drop-down menu. A self-service car wash charges $4 for the initial 5 minutes plus an additio
arlik [135]

Answer: For m\geq15

\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5

Nick does not has enough money to follow this recommendation.

Step-by-step explanation:

Given: A self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that.

Let y be the cost for car wash for m minutes then

y=4+0.75(m-5) such that at m= 5 , y=4 which is the cost for car wash (dollars) for first 5 minutes.

Also, A car enthusiast magazine recommends spending at least 15 minutes to properly wash a car.

For m\geq15

\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5

But Nick has $10 which is less than $11.5, so he does not has enough money to follow this recommendation.

Name three other common multiples of 8 and 12
Sladkaya [172]

The first few multiples of 8 are: 8, 16, 24, 32, 40, and 48. The first multiples of 12 are: 12, 24, 36, 48, 60, and 72.

Common multiple of 8 and 12 are 24 and every subsequent multiple of 24.

As 8×3=24

12×2=24

So 24 is a common multiple of 8 and 12 this means the other common multiples of 8 and 12 are the multiples of 24 like 48, 72, 96 etc.
