Answer:
m = 0.2508 g
Step-by-step explanation:
We know that for continuous exponential decay, we usually use the format;
N = N_o•e^(kt)
Where N and N_o represent amount after time t and intial amount respectively. And k is decay rate.
But in this case, we are dealing with mass.
Thus, we will use;
m = m_o•e^(-kt)
We are given;
Initial mass; m_o = 0.5 g
Time after decay; t = 60 days
Decay rate; k = 1.15% per day = 0.0115 per day
Thus;
m = 0.5e^(-0.0115 × 60)
m = 0.5 × 0.5016
m = 0.2508 g
When two angles are supplementary angles then the sum of the angles is .
Let the supplementray angle of ∠EGB = ∠x.
So we know that ∠x + ∠EGB =
Now to find angle x we will move angle EGB to the right side. Angle EGB is added there. So to move it we will use reverse operation. Reverse operation of addition is subtraction. So we subtract angle EGB from both sides. We will get,
∠x + ∠EGB - ∠EGB = - ∠EGB.
∠x = - ∠EGB
So we have got the required equation to find the angle which is supplementary to the angle EGB.
The slope is defined as
So, we have the follwing equation:
Answer:
Subtract:
2/3 - 1/2 = 2/3 • 2/2 - 1/2 • 3/3 = 4/6 - 3/6 = 4-3/6 = 1/6
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(3, 2) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 2 = 6. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - two thirds minus one half = one sixth.
Hope this helps
