If you have 1912 copies x 305 runs per copy. Would I estimate by multiplying 1912 copies per run by 305 runs.
melisa1 [442]

Answer:

Total = 583160

Step-by-step explanation:

Given

Copies = 1912

Runs = 305 per copy

Required

Determine the total number of runs

To do this, we multiply the number of copies by the number of runs per copy.

i.e.

Total = Copies * Runs

Substitute values for Copies and Runs

Total = 1912 * 305

Total = 583160

<em>Hence, there are 583160  in total</em>

A cone with a volume of 640.23 has a radius of 7. What is the height of the cone?
USPshnik [31]

Answer:

Your answer is about 12.48

Step-by-step explanation:

h = 3(V/pi*r²)

h = 3(640.23/pi*7²)

h = 3(640.23/153.93804)

h = 3(4.157516881)

h = 12.47703

kakasveta [241]
Since the probability that 50% of the babies born are female, she could use any probability model that is 50/50.

For example, she could flip a coin. Or she could roll a die, using the even numbers for girls and odd numbers for boys.

<h3>Answer:  29 miles (approximate)</h3>

======================================================

Explanation:

Segment AB is already given to be 19 miles long.

I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.

Use the law of cosines to find the missing side

a^2 = b^2 + c^2 - 2*b*c*cos(A)

a^2 = 12^2 + 19^2 - 2*12*19*cos(138)

a^2 = 843.874040417691

a = sqrt(843.874040417691)

a = 29.0495101579647

a = 29 when rounding to the nearest whole number

Side BC is roughly 29 miles long.
