The question is ambiguous.
A is right if the second hour is in terms of the original amount (16 grams). That is not how it should be done, but there is nothing in the problem restricting us from doing it that way.
B is right the way most people would do the problem. I would say you should accept this as the right answer. The 4.5% is taken away from what was left after the first hour. I would do it that way left to my own devices.
C. The % conversions are not correct. Those conversions are 35% and 45%
C is not even in contention for being right.
D Same problem as C
Answer:
The volume of the sphere is 
Step-by-step explanation:
we know that
The volume of cylinder is equal to
we have
substitute
simplify
Remember that
A sphere and a cylinder have the same radius and height
so
The height of cylinder is equal to the diameter of sphere
h=2r
substitute
-----> equation A
The volume of the sphere is equal to
substitute equation A in the formula of the volume of sphere
Answer:
1/12clay each bowl
Step-by-step explanation:
Since we know she used 1/3, simply divide 1/3 by 4 to get your answer.
1/3 / 4/1
1/3 * 1/4
1/12
Answer:
b
Step-by-step explanation:
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
