The substance of 256 gm will be decayed into 1 gm in 800 years.
Step-by-step explanation:
Given,
The substance decays 75% in every 600 years.
Amount of substance = 256 gm
To find the the time the substance to decay to 1 gm.
Now,
75% decay in 600 years
1% decays in 600÷75 years
100% decays in ×100 years
= 800 years
Hence,
The substance of 256 gm will be decayed into 1 gm in 800 years.
Answer:
6 seconds
Step-by-step explanation:
-12 m is the displacement
Distance covered is 12m
Distance : time
2m : 1 sec
12m : t sec
2/1 = 12/t
t = 6 sec
Answer:
The value of the slope in this equation is 50
The interpretation is that the rate of change in the cost of the phone bill per unit change in gigabytes of data used each month is 50
Step-by-step explanation:
To answer this question, we need to compare the given equation with the equation of a straight line graph.
The equation we have is;
c = 50g + 75
comparing this with the equation of a straight line, we have
y = mx + c
where m represents the slope and c is the y-intercept
So comparing both, the slope of the equation is 50.
The slope is always the co-efficient of the value on the x-axis
So what does this mean?
The slope also called the gradient represents the rate of change of the y-term divided by the rate of change of the x-term. In simpler terms, when we talk of the slope, we mean the rate of change of the y term per the unit change of the x-term.
So what we mean in this case is the rate of change in cost of the phone bill per unit change in gigabytes of data used each month is 50
