Answer:yessir
Step-by-step explanation:
Each bag of popcorn was $3.33 dollars because you divide 40 dollars by 12 bags. That is how you get your answer.
Turning up the edges of the sheet metal will result in the 20 inches of
metal being divided into x inches of the first side, then the unknown
width of the gutter (let's call it "y") and then again x inches for the
second side.
As a picture:
x|______|x/y
As a formula:
20 = x + y + x = 2x + y
Resolving this to y we get:
20 - 2x = y
and switching it around:
y = 20 - 2x,
Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).
A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be:
A(x) = 20x - 2x^2
Answer:
0.7 pounds of fruit
Step-by-step explanation:
Step 1. Add all fruit Ashley has been given to Aliyah, Brendan and Arley
Find the sum of;
1.3 pounds for Aliyah
2.4 pounds for Berndan
<u> 1.2 pounds for Arley </u>
4.9 pounds of fruits
Step 2. Subtract the total pounds given from the total pounds of fruit Ashley had.
5.6 pounds - 4.9 pounds = 0.7 pounds left
Answer; Ashley has 0.7 pounds of fruits left
