Answer:
The diameter of the circle O is <em>12 units</em>
Step-by-step explanation:
There is no data in the image provided. To better help you, I'm assuming we have an arbitrary value of
and the triangle B0C is right
<u>Relations in the Circle</u>
The diameter (D) is twice the radius (r) and the radius is the distance measured from the center of the circle to any point of the circumference.
Since the triangle B0C has a right angle, BD is the hypotenuse and 0B=0C=r
Applying Pythagoras's theorem:
Thus we have
The diameter of the circle O is D=2(6) = 12 units
Answer:
-1.25
Step-by-step explanation:
Better to write this as
a(n)= -5(1/2)^(n-1)
Then the 3rd term is a(3) = -5(1/2)^(3 - 1), or a(3) = -5(1/2)^2 = -5/4 = -1.25
Answer:
Brooke
Step-by-step explanation:
We can solve this by figuring out how far each person runs a second
Stephanie runs 12 feet a second so nothing needs to be done here
Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet
Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75
Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18
Brooke obviously runs the furthest in one second and therefore she's the fastest runner
The mean is the average of a given data set and can be obtained by taking the sum of all numbers and dividing that by the amount of numbers in the data set.
58 + 43 + 33 + 69 + 41 + 74 = 318
There are 6 numbers in the data set.
318 / 6 = 53
Answer:
If an object on Mercury weighed 25lb, it would weigh 75lb on Earth
(25 * 3 = 75)
The answer is b
