Answer:
Step-by-step explanation:
The formula for simple interest is
I = Prt
where I is the interest earned, P is the initial deposit, r is the rate in decimal form, and t is the time in years. For us,
I = 125(.03)(3) which gives us an interest amount of
I = 11.25
To find out how much money she has total after that interest builds up, we add that interest amount to the initial investement amount to get
125 + 11.25 = 136.25
The angles of an equilateral triangle are always 60°

Answer:
Percentage of (226Ra) after 900 years is 68%
Step-by-step explanation:
Let P(t) be the amount of (226Ra) present at any time t
Half life of (226 Ra) = 1599 years
If P₀ is initial amount of (226 Ra) then after 1599 years
P(1599)=P₀/2
Decay i amount of radioactive substance is related to time t as
To find value of k
Percentage of radioactive element is:
Amount after 900 years
First, find the function that represents x and y.
x is the number of 8 oz jars
y is the number of 16 oz jars
function: 8x + 16y = 240
x-intercept: y = 0 => 8x = 240 => x = 30 => (30,0)
y-intercept: x = 0 => 16y = 240 => y = 15 => (0, 15)
Answer: (0,15) and (30,0)
