Answer:
1 : 4
Step-by-step explanation:
Given:
Favorite Music :
Pop _____ 7
Country __ 5
Dance ___ 4
Total number of students surveyed :
(pop + country + dance). = (7 + 5 + 4) = 16
Number who chose dance = 4
Ratio of dance to total number surveyed
4 : 16 = 1 : 4
1 :4 (lowest term)
Answer:
g(f(x)) = 8x^3-24x^2+34x-18
Step-by-step explanation:
The composition is ...

According to the graph, the answer is C. 150
Answer:
$8.88
Step-by-step explanation:
24yds needed = 864 inches
864/150 = 5.76 so he'll need 6 spools
6x 1.48 = $8.88
Answer:
approximately 7 hours
see the explanation
Step-by-step explanation:
The picture of the question in the attached figure
Let
x ----> the time worked in hours
y ----> the amount earning in dollars
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
so
In this problem we have a proportional relationship
step 1
Find approximately how many hours would it take Delia to earn $250 ?
Looking at the graph
For y=$250 The value of x is approximately 7 hours
see the attached figure N 2
step 2
Find the exact value
from the graph take the point (5,175)
Find the value of k
----> 
The linear equation is

For y=$250
substitute

solve for x
