Answer:
B. 21 and 19/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
21.76=21.761
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
21.761×100100=2176100
Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
2176÷4100÷4=54425
Simplify the improper fraction,
=211925
In conclusion,
21.76=211925
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
Answer:
Step-by-step explanation:
See comment for complete question.
From the complete question, we have:
Required
Determine the other zero
The zeros can be represented as:
Considering the 3rd zero, which is a complex number.
If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero
A conjugate pair is given as:
and 
For
The conjugate pair is:
Hence, the other zero is:
