Answer:
27850
Step-by-step explanation:
9/100 = x/30.95
9 x 30.95 = 278.5
278.5 x 100
Use the equation y=mx + b. m is the slope.
so in your equation, the slope is 3.
to get the y int, we set the equation equal to 0
so, 0=3x + 5,
to solve that, subract 5 from both sides and you get: -5=3x.
next, divide both sides by 3 and you get
x= -5/3
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
