Answer:
7/25
Step-by-step explanation:
if 7% are defective and they order 25% of their lightbulbs from Baker that will be your answer.
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3
which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21
Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.
2nd degree and in form
ax^2+bx+c
it is a prabola
the minimum cost is the vertex (every parabola has only one, min or max)
minimum cost is the vertex
vertex=-b/(2a)
a=0.4
b=-208
vertex=-(-208)/(2*0.4)
vertex=208/0.8
vertex=260 (means 260 dresses)
that is x value
subsitute for y value
C(x)=0.4(260)^2-208(260)+37365
C(x)=10325
minimum cost is $10,325
