Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Company 1:
Variable cost= $12 per foot
Company 2:
Fixed cost= $250
Variable cost= $15 per foot
<u>To determine the total cost of each company, we need to use the following formulas:</u>
Company 1:
Total cost= 12x
x= number of feet
Company 2:
Total cost= 250 + 15x
x= number of feet
<u>For example, for 150 feet:</u>
Company 1:
Total cost= 12*150= $1,800
Company 2:
Total cost= 250 + 15*(150 - 100)
Total cost= $1,000
Answer:
Max is currently 12 years old.
Step-by-step explanation:
Zeke's current age = 8 years
Lets take Max's current age as
years.
Then Max's age 3 years ago = 
Double Max's age 3 years ago = 
Double Max's age 3 years ago + Zee's current age = 26
⇒
+
= 
=
=
(Simplifying the brackets)
=
=


So Max's current age is 12 years.
Answer:
50
Step-by-step explanation:
.25 goes into 100 4 times, 50 goes into 200 4 times :)
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>
