Answer:
30 grams
Step-by-step explanation:
half life is 60 days so every 60 days the amount 480 grams will be half
in 240 days will decay 240 /60 = 4 times
once 480 /2 = 240
twice 240 /2 = 120
trice 120 / 2 = 60
four times 60/2 = 30 grams will be left
Answer:
There is no picture or graph to go with the question so I am afraid I will not be able to give you a specific answer.
To find out if a point (x, y) is on the graph of a line, we plug in the values into that equation and see if we get a true statement, such as 10 = 10. If we get something different, like 6 = 4, we know that the point is not on the line because it does not satisfy the equation. Plug in (-301, 601) into the equation of the line to see whether that point lies on it or not.
Step-by-step explanation:
Suppose the equation of the straight line that passes through E and F is this:
y = 7x + 2
We are to figure out whether or not the point (1, 10) lies on that line. In order to do this we would plug in (1, 10) into the equation, with 1 being x and 10 being y.
10 = 7(1) + 2 = 7 + 2 = 9
10 = 9 is a false statement. Therefore, the point (1, 10) does NOT lie on the line y = 7x + 2.
If you were to provide an image or graph that shows the equation of line AB then perhaps I would be able to answer your question with a specific answer.

Answer:
422.39
Step-by-step explanation:
circle area with
π r²
π*12*12 = 452.389342117
Minus area of the rectangle
452.389342117 - 3 * 10
= 422.389342117
rounded to the nearest hundredth:
422.39

Answer:
A. <u>Distance of the lightning after 4 seconds = 744,000 miles</u>
<u>B. Distance of the lightning after n seconds = 186,000 * n</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Speed of lightning = 186,000 miles per second
Speed of sound = 750 miles per hour
2. A. If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning?
Distance of the lightning after 4 seconds = 186,000 * 4
<u>Distance of the lightning after 4 seconds = 744,000 miles</u>
<u>B. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?</u>
<u>Distance of the lightning after n seconds = 186,000 * n</u>
