Answer:

C) 314 feet.

Step-by-step explanation:

We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.

The distance around the track would be equal to circumference of circle.

\text{Circumference of circle}=2\pi r, where r represents radius of circle.

Since we have been given across distance, so it will be diameter of track.

To find radius we will divide across distance by 2.

r=\frac{100\text{ ft}}{2}=50\text{ ft}

Upon substituting our given values in circumference formula, we will get:

\text{Circumference of circle}=2\times 3.14\times 50\text{ ft}

\text{Circumference of circle}=100\times 3.14\text{ ft}

\text{Circumference of circle}=314\text{ ft}

Therefore, the distance around the track is 314 feet and option C is the correct choice.

PLEASE URGENTLY ANSWER THESE 2 QUESTIONS, I WILL PROVIDE MORE POINTS AND CROWN YOU BRAINLIEST IF YOU DO!!!
Doss [256]

Answer:

1. I would think it would be a appropriate to use a normal model to figure this out because sometimes when you are using stuff online you can get the same number like 20 times in a row, whereas, if you use a real dice, you most likely won't roll the same number 20 times.

2. { sorry two doesn't make sense }

Answer:

\boxed{\boxed{x=\dfrac{\pi}{3}\ \vee\ x=\pi\ \vee\ x=\dfrac{5\pi}{3}}}

Step-by-step explanation:

\cos(3x)=-1\iff3x=\pi+2k\pi\qquad k\in\mathbb{Z}\\\\\text{divide both sides by 3}\\\\x=\dfrac{\pi}{3}+\dfrac{2k\pi}{3}\\\\x\in[0,\ 2\pi)

\text{for}\ k=0\to x=\dfrac{\pi}{3}+\dfrac{2(0)\pi}{3}=\dfrac{\pi}{3}+0=\boxed{\dfrac{\pi}{3}}\in[0,\ 2\pi)\\\\\text{for}\ k=1\to x=\dfrac{\pi}{3}+\dfrac{2(1)\pi}{3}=\dfrac{\pi}{3}+\dfrac{2\pi}{3}=\dfrac{3\pi}{3}=\boxed{\pi}\in[0,\ 2\pi)\\\\\text{for}\ k=2\to x=\dfrac{\pi}{3}+\dfrac{2(2)\pi}{3}=\dfrac{\pi}{3}+\dfrac{4\pi}{3}=\boxed{\dfrac{5\pi}{3}}\in[0,\ 2\pi)\\\\\text{for}\ k=3\to x=\dfrac{\pi}{3}+\dfrac{2(3)\pi}{3}=\dfrac{\pi}{3}+\dfrac{6\pi}{3}=\dfrac{7\pi}{3}\notin[0,\ 2\po)

An oil tanker empties at 3.5 gallons per minute. Convert this rate to cups per second. Round to the nearest tenth.
ss7ja [257]
If given ratio is 3.5 gallons per minute and we want to cups per second we can do this knowing that 
1 gallon= 16cups
1min = 60sec
ratio=3.5\frac{gallon}{minute}=3.5* \frac{16cups}{60 seconds}  =3.5*0.266=0.933 \frac{cups}{sec}
Its the result
