Answer:
h≈2.12
Radius =9
volume = 180
Step-by-step explanation:
h=3V / πr2=3· 180 / π·9^2 ≈ 2.12207
Answer:
25/9
Step-by-step explanation:
when dividing fractions the method is "keep, change, flip"
you keep the first fraction how it is - keep
you change the division sign into a multiplication sign - change
and you flip the last equation - flip
so it turns into 5/6 * 10/3
that equals 50/18 and you can simplify that to 25/9
Answer: 42/13
Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:
k+ 21 - 14k = -21
Isolate the variable:
k - 14k = -21-21
13k= -42
divide the sides by -13.
42/13
Answer:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no solutions. If it's equal to 0, there is one solution.

We know that
[probability that both have the secret decoder ring]=(13/47)*(12/46)
[probability that both have the secret decoder ring]=(156/2162)
[probability that both have the secret decoder ring]=0.0722-------> 7.22%
the answer is 0.0722 (7.22%)
