Express the radius of the Sun as a proportion to radius of Earth:
695500/6378 = 109.04...
Now if a baseball would represent Earth, the model for Sun would have to be about 110 times larger than a baseball. A baseball is about 3" in diameter, so the model for Sun would have to be about 330" (or 27 feet) in diameter.
The answer should be no it is not reasonable to use baseball as a model for the Earth because the Sun would need to be about the size of a hot air balloon!
Answer:
C. 1/9
Step-by-step explanation:
Assuming the selections are independent, their joint probability is the product of the probabilities of the individual events.
P(pink square) = (# pink squares)/(# squares) = 16/60 = 4/15
P(red or blue round) = (#red or blue rounds)/(# rounds) = 15/36
Then the joint probability is ...
P(defined event) = (4/15)(15/36) = 4/36 = 1/9
Answer:
320 numbers with 3 digits that are odd
Step-by-step explanation:
The ball will hit the ground at 2 seconds.
Step-by-step explanation:
Given that,
The path of the ball = h(x)=−2x2+1x+6
Here,
x is the time while h is the height of ball.
When the ball will hit the ground, the height will become zero. Therefore,
h(x)=−2x2+1x+6
0 =−2x2+1x+6
or
2x2 -1x - 6 = 0
This is a quadratic equation, hence by applying quadratic equation formula:
here,
a = 2
b = -1
c = -6
Putting these values in formula, we get
x = 2, -3/2
As the time cannot be negative. Therefore, the ball will hit the ground at 2 seconds.
Answer:
x = 29 degrees
Step-by-step explanation:
We know that all of the angles inside of a right triangle add up to 180. We also know that a right angle is 90 degrees. We can do 61 + 90 = 151. 180 - 151 = 29. This means that x = 29 degrees.
