Emmett participated in a race. During the race, he ran 5 miles north and then ran 12 miles west. What is the shortest distance that Emmett must travel to return to the starting point?

Answers

I'd suggest you sketch this situation.  If you did, you'd likely see right away that the shortest distance back to the starting point would be the hypotenuse of the right triangle whose legs are of lengths 5 miles and 12 miles.

The angular velocity of a point with radius 8 feet is 10 pi radians per second. Find the speed of the point.0.8pi ft/sec
1.25pi ft/sec
80pi ft/sec

Answers

Answer:

80π feet/ second.

Step-by-step explanation:

Angular velocity of a point = 10π radians per second

Radius of the circle is 8 feet.

We know the formula of angular velocity is

Angular velocity = (speed)/(radius)

10π = (speed)/(8)

Speed = 80π feet/ second.

Option C is the answer.

Answer: 80\pi\text{ ft/sec}

Step-by-step explanation:

Formula : \text{Speed= Angular velocity x Radius}   (1)

We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.

i.e. Radius = 8 feet

Angular velocity = 10\pi radians per second.

Then, the speed of the point will be :-

\text{Speed= }10\pi * 8   [using (1)]

=80\pi\text{ ft/sec}

Hence, the speed of the point =80\pi\text{ ft/sec}

1. The mode is C. 18
2. The median is B. 16
3. The mean is D. 14.25
4. The median is 2.3
5. The mean is 18

1) the mode is the number that repeats the most in a given set of numbers, so the answer would be c, 18
2) the median is b, 16 (if you put the numbers in chronological order, there are two middle numbers, to get the median you have to average those two numbers)
3) the mean is d, 14.25 (add all the numbers up and divide by the amount of numbers that you have [if you have 5 numbers, you divide by 5])
4) the median is 2.3
5) the mean is 18

Convert 7qt/min into gallons per hour

Answers

we first need to turn every thing into the same unit of measure ment

1 gallon=4 quarts
60 minutes=1hour

7*60=420  420 is how many quarts per hour but we want gallons so we want to divide by 4
420/4=105
105 gallons per hour
so
qt=quart
4 quart=1 gallon
1 quart=1/4 gallon
min=minute
60 minutes in 1 hour
1 minute=1/60 hour

so 7 quarts=7 times 1/4 gallons=7/4 gallons
1 minute=1 times 1/60 hours=1/60 minutes

7/4 gallons per 1/60 minutes
(7/4gal)/(1/60h)
we don't really need to divide so multiply the whole thing by (1/60)/(1/60) to clear bottom fraction
(7/4 times 60/1)/(1/60 times 60/1)=(420/4)/(60/60)=(420/4)/(1) =420/4=210/2=105/1=105 gallons per hour

the asnwer is 105 gallons per hour
