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:
WOMP WOMP WOMP!!!
Step-by-step explanation:
Answer: 1 and 3
Step-by-step explanation:
The value of y will be 60 so the correct answer is option C.
<h3>What is a graph?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
There is a linear relationship between the two variables x and y. For the given data in the table as well as in the graph. The expression for the two variables will be written in the form of an equation as follows:-
The expression for the data in the table:-
y = 25 x now at x = 12
y = 25 x 12 = 300
The expression for the values in the graph:-
y = 30x at x = 12
y = 30 x 12
Y = 360
How much more would the value of y be on the graph will be calculated as:-
Value = 360 - 300
Value = 60
Therefore the value of y will be 60 so the correct answer is option C.
