vaieri [72.5K]3 years ago
5 0

Answer:

0.01

Step-by-step explanation:

Water is non viscous liquid and it has less density. The measure volume of water is 10.03 ml at 25 degree Celsius which is used to identify the standard deviation of the water.

Average volume of water 10.03ml.

Standard deviation is 0.0001 + 0.0001

Standard deviation is \sqrt{0.0002}  = 0.01.

Light travels at 186,000 miles per second. How many FEET does it travel in a microsecond? (A microsecond is a millionth of a sec
Maslowich
1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.

A horse trot in a circle around it's trainer at the end of a 31 foot long rope. Find the area of the circle that is swept out. R
Mnenie [13.5K]
So, imagine the trainer is in the very middle of the circle and he is holding out a rope that's attached to the horse. The rope here from the trainer to the horse represents the radius of the circle. The horse trots around the trainer (middle point) in a circle.
The formula to find area of a circle is A = pi*r^2 (pi times r squared where r is radius)
We know that the radius of the "circle" here formed as the horse trots around the trainer is 31 (the 31 foot long rope). 
So let r = 31 & plug the value into the formula to find circle area.
A = pi*31^2 = 3019.07054
The area is therefore 3019.07 square feet. (rounded)

Answer:

Slope = y^2 - y^1 / x^2 - x^1

Graph n1

Slope = -5 - 1 / -6 - 2

Graph n2

Slope = -5 - 3 / 3 - 5

Graph n3

Slope = 3 - 0 / -4 - 5

Denzel has a new puppy that weighs 12 pounds. The vet says that the puppy is now at about 20% of its adult weight. What will be
olchik [2.2K]

Answer:

60 pounds

Step-by-step explanation:

To find the adult weight, multiply 12 by 5.

Since 12 pounds is 20% of the adult weight, 100% of the adult weight would be 12 times 5.

12(5)

= 60

So, the adult weight of the puppy will be 60 pounds
