The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
Answer:
532+50pi
or exact: 689.08
Step-by-step explanation:
Answer:
The ball reaches 44 ft above the ground after 4 sec.
Step-by-step explanation:
Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t. Indicate exponentiation with " ^ "
-16t^2 + 300 = 44 becomes
-16t^2 + 256 = 0, or 16t^2 = 256. Then, taking the square root of both sides, we get:
4t = 16, or t = 4 sec. The ball reaches 44 ft above the ground after 4 sec.
Since the choices is from 0000 to 9999, therefore there
are a total of 10,000 possibilities.
The possibilities that the number begins with a 3 and ends
in a 2 or 0 is:
possibilities = 1 * 10 * 10 * 1 + 1 * 10 * 10 * 1 = 200
Therefore the probability is:
P = 200 / 10,000 = 0.02 = 2%
<span>So there is a 2% probability.</span>
