the table shows the types of popcorn buckets sold at a concession station for one day. what percent of the buttered popcorn buck
ets were large
1 answer:
Hi there! The answer is about 23%
First we need to find the total amount of buttered popcorn sold. This is 182 + 140 + 97 = 419 buckets.
To find the percentage of the buttered popcorn buckets that were large, we use the following formula:
Filling in this formula brings us to our answer:
Hence, the answer is about 23%

Answer:
a) 1650 m
b) 1677.05 m
Step-by-step explanation:
Hi there!
<u>1) Determine what is required for the answers</u>
For part A, we're asked for solve for the horizontal distance in which the road will rise 300 m. In other words, we're solving for the distance from point A to point C, point C being the third vertex of the triangle.
For part B, we're asked to solve for the length of the road, or the length of AB.
<u>2) Prove similarity</u>
In the diagram, we can see that there are two similar triangles: Triangle AXY and ABC (please refer to the image attached).
How do we know they're similar?
- Angles AYX and ACB are corresponding and they both measure 90 degrees
- Both triangles share angle A
Therefore, the two triangles are similar because of AA~ (angle-angle similarity).
<u>3) Solve for part A</u>
Recall that we need to find the length of AC.
First, set up a proportion. XY corresponds to BC and AY corresponds to AC:
Plug in known values
Cross-multiply
Therefore, the road will rise 300 m over a horizontal distance of 1650 m.
<u>4) Solve for part B</u>
To find the length of AB, we can use the Pythagorean theorem:
where c is the hypotenuse of a right triangle and a and b are the other sides
Plug in 300 and 1650 as the legs (we are solving for the longest side)
Therefore, the length of the road is approximately 1677.05 m.
I hope this helps!
