You want to add 12 and 143 witch would be 155 and then you want to subtract that from 71 and that will give you D
Answer:
The equation is at a rate of -23%.
Step-by-step explanation:
Decay can be represented by the equation . We can find the rate at which it decays by using t=3 hours and A=3000. This means in this context.
After substituting, we divided by 6000 to each side to get 0.5 on the left. Now to solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know so we were able to cancel it out and divide both sides by 3.
We solve with a calculator
We change -0.23 into a percent by multiplying by 100 to get -23% as the rate.
The equation is
The first is if the corresponding angles, the angles that are on the same corner at each intersection, are equal, then the lines are parallel<span>. The second is if the alternate interior angles, the angles that are on opposite sides of the transversal and inside the </span>parallel lines<span>, are equal, then the </span>lines are parallel<span>.</span>
