Answer:
The number was 20
Step-by-step explanation:
As the average is 11 and the numbers are 4, so the total sum of numbers will be 11X4=44. now the sum of three numbers are (20+8+4)=24. So the last number will be= (44-24)=20. :)
Answer:
887.74
Step-by-step explanation:
Answer: true
Step-by-step explanation:
The polar cordinates are (6, pi/2)
We know that a imaginary number can be written, in polar cordinates (R, θ)
Z = R*(cos(θ) + i*sin(θ))
Then, the point (6, pi/2) is:
Z = 6*(cos(pi/2) + i*sin(pi/2)) = 6i
The other representation is (a, b) and in this case the imaginary number is
Z = a + b*i
In this case we have (0, 6) so:
Z = 0 + 6*i
Then you can see that the statement is true,
Answer:
117, 118
Step-by-step explanation:
if 2 consecutive numbers have a sum of 235, then
Let the 2 numbers be n and n+1
Given That:
n + n+1 = 235
Simplify and solve:
2n + 1 - 235
2n = 234
n = 117.
If n = 117, then n +1 = 118. These are the 2 consecutive numbers.
Hope this helps.
Good Luck
