Answer: 70.909090909091%
Step-by-step explanation: Reading through the problem we have <em>78 is</em>, that's 78 equals, <em>what percent</em>, x/100, <em>of 110</em>, times 110.
It's important to understand that <em>percent</em> means over 100 so what percent would simply mean <em>x/100</em> or any variable but I will be using x.
So we have the equation
So cross canceling the 110 and 100 to 11 and 10, we have
Multiply both sides by 10 to get rid
of the fraction and we have 780 = 11x.
Now divide both sides by 11 and 70.909090909091 = x.
So, 78 is 70.909090909091% of 110.

Answer:
34, D
Step-by-step explanation:
Change 4 and 1/4 to an improper fraction
4 1/4 = 17/4
Now, you would divide 17/4 by 1/8...
17/4 divided by 1/8
Reciprocate the fraction 1/8 and change the division sign to multiplication to get...
17/4 multiplied by 8/1
= 136 / 4
Simplify
136 / 4
= 34
So, you can grow 34 plants.
Hope this helps!
Solution:
Given: zj = 3- j2, zz = - 4 + j3
Part a:
zj = 3- j2 =
zz = - 4 + j3 =
Part b:
|zj| = |3− j2| = √3² +(−2)² = √13 = 3.60
|z1| = √(3− j2)(3+ j2) = √
13 = 3.60.
Part c:
With the help of part a:
z1z2 =
