Answer:
4.44 * 10^11
Step-by-step explanation:
I can only answer part A, apologies.
Scientific notation cannot be anything less than 0, or greater than 10. Thus, you have to move the decimal place to the left to get it to a place where it turn 444000000000 into a number that fit these requirements.
To get it to fit such requirements, you move the decimal to the left exactly 11 times. This eleven is important because it is the exponent of 10.
So basically you get the 4.44 by moving the decimal place 11 times to get the number to be between 0 and 10, and then the number of times you move the decimal is the number that your exponent will be. (the exponent isn't negative because if of what direction the decimal end up moving in if you were to move it back to its original place and turn your 4.44 * 10^11 back to its original form. It moves to the right, which is a positive movement. If it were to move to the left to make it back into 444 billion, THEN would it be a negative exponent.)
Answer:
D
Step-by-step explanation:
First put the data from smallest to largest
12 points, 17 points,21 points, 23 points, 24 points, 28 points,29 points
The left end of the whisker should be 12 (This eliminates graph a)
The right end of the whisker should be 29 (This eliminates graph b)
There are 7 points
The middle point is 4
The 4th point is 23
That is the line in the middle of the box (This eliminates graph c)
The lower line of the box is at at point 2 = 17
The upper line of the box is at point 6 = 28
This leaves us with graph D
I think you're talking about the black spot on the surface of the Earth,
where the end of the Moon's shadow falls, and anybody inside that
circle sees the Sun completely covered for a few minutes.
The size of that spot varies. It depends on exactly how far the Moon
is from the Earth, and exactly how far both bodies are from the Sun.
The longest possible totality viewed from a single location is about
7-1/2 minutes, when all the geometry is just right. Then, I believe,
the black spot on the Earth's surface is something like 170 miles
across, moving at around 24 miles a minute, or 1,460 miles per hour.
What exactly do you need help with?!
The constant of proportionality is 5. For every time the total area "A" is multiplied by one the length is multiplied by 5.
