What is speed?

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Frieda drove 20 miles in 24 minutes. The speed is calculated as,

S = 20 / 24

S = 5/6 miles per minute

The number of miles that she drives in 6 minutes is calculated as,

D = 5/6 x 6

D = 5 miles

What is 3/5 of 6,000

Answers

we have to find what is 3/5 of 6000 
so basically of means in mathematically multiply.. ( of = multiply )
So now let's solve the problem 
(3)/(5) of 6000
i.e (3)/(5) * 6000
 = 3 * 1200
 = 3600

So your correct answer is 3600

Hope this helped you :)
for this question the only thing you should do is to multiply 3/5 by 6000 so you will have:
3/5 * 6000 = 3,600 :)))
i hope this is helpful
have a nice day 

In circle K , diameter CD is drawn and point E is located on the circle such that CE=16 and DE=30 .What is the length of the radius of circle K?

Answers

Answer:

The length of the radius of the circle K is 17\ units

Step-by-step explanation:

we know that

The triangle CDE is a right triangle with the 90 degree angle at point E

so

Applying the Pythagoras Theorem

Find the length of CD (diameter of the circle K)

CD^(2)=CE^(2)+DE^(2)

substitute the values

CD^(2)=16^(2)+30^(2)

CD^(2)=1,156

CD=34\ units

Find the radius

Remember that the radius is half the diameter

so

r=34/2=17\ units

Simplify 15(5b+3)
Please help me I don't understand at all

Answers

15(5b+3) \n \n 15 * 5b + 15 * 3 \ / \ distribute \n \n 75b + 15 * 3 \ / \ simplify \n \n 75b + 45 \ / \ simplify \n \n

The final result is: 75b + 45.
