The answer looks to be C.
To get her output per hour, you will have to divide her output by the time she took to produce it (in hour)
So per hour she would produce:
9/2 ÷ 1/6 = 9/2 x 6 = 27
The answer is 27 widgets per hour
Answer: 9 inches.
Step-by-step explanation:
Use a proportion for this problem
2/3=6/x
Cross multiply
2x=18
Simplify
x=9
Answer:
1,3,6,10,15,21,…..
These are all the sum of natural numbers upto the n
So, in this series
1st Term = 1
2nd Term = 1+2 = 3
3rd Term = 1+2+3 = 6
4th Term = 1+2+3+4 = 10
So,
Term - n = 1+2+3+….+n = n(n+1)/2
That’s your answer n(n+1)/2
Good Luck
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
and 
can be expressed in complex form, with 
= i
= 
= 
× = 8i
= 
= 
× = 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = ( )² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
