Answer: (27- 4/3 pi) r^3
Step-by-step explanation: 1. Volume of a cube: V= a^3, V= 3^3 , V=27
2. Volume of a sphere: V=4/3 pi r^3 ......
Answer:
y = 11
Step-by-step explanation:
In most algebraic problems, you need to isolate the variable (by canceling out some other value) to get the answer to do so in this equation, subtract 8 from both sides. Then you get 11 = y
-Hai There!
-Your answer to the question above is 6.
-Glad I could help! (:
The coefficient 6.3 rounds to 6
The coefficient 9.9 rounds to 10
So we go from this
(6.3 x 10^(-2))(9.9 x 10^(-3))
To this
(6 x 10^(-2))(10 x 10^(-3))
Multiply out the coefficients to get 6*10 = 60
Add the exponents to get -2 plus -3 = -5
So we end up with 60 x 10^(-5)
Be careful. This is NOT the final answer. We need to convert this to scientific notation
60 = 6*10 = 6 x 10^1
60 x 10^(-5) = ( 6 ) x 10^(-5)
60 x 10^(-5) = ( 6 x 10^1 ) x 10^(-5)
60 x 10^(-5) = 6 x (10^1 * 10^(-5)
60 x 10^(-5) = 6 x 10^(1+(-5))
60 x 10^(-5) = 6 x 10^(-4)
The final answer is choice A
7, 5, 3, 1 is an arithmetic sequence with common difference (d) = -2 and first term (a) = 7.
Tn = a + (n -1)d
T50 = 7 + (50 - 1) x -2 = 7 + 49 x -2 = 7 - 98 = -91
50th term = -91
