Take the cos-1 of both sides to get 3x=30 then divide by 3 to get ×=10
Answer:
110
Step-by-step explanation:
80 + 30
= 110
$630
The total perimeter is 42 and 42x15=630
That ones a hardddd one ill let someone else answer thatttttt
Answer:
The constant of proportionality is equal to 4
Step-by-step explanation:
The picture of the question in the attached figure
Let
y ----> the total cost in dollars
x ----> the number of bags of peanuts
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
To find out the constant of proportionality, we need to take one point from the graph
take the point (1,4)
Find the value of k

substitute the value of x and the value of y
