Answer:
ok if u follow bwck and give me brainliest i need one more until next rank
Step-by-step explanation:
Original question is missing the details so I'm attaching the details after searching from internet. (check attached picture)
Let number of competitor = x
Cost per competitor for Straw Bridge contest = $5.50
Then cost for x competitors = 5.50x
Fixed extra expense = 34.60
So total cost for Straw Bridge contest = 5.50x+34.60
Cost per competitor for Card Tower contest = $4.25
Then cost for x competitors = 4.25x
Fixed extra expense = 64.60
So total cost for Card Tower contest = 4.25x+64.60
Total cost for both contests = (5.50x+34.60)+(4.25x+64.60) = 9.75x+99.2
FEA club will charge $10 for entrance per competitor
So total revenue for x competitors = 10x
Now profit for x competitors is give by
Profit = Revenue - cost
Profit = 10x- (9.75x+99.2)
Profit = 0.25x-99.2
Now we have to find profit for 32 competitors so plug x=32 in profit equation
Profit = 0.25x-99.2 = 0.25*32-99.2 = 8 -99.2 =-91.2
Which is negative.
So that means there is no profit. Infact they are still in loss.
Answer:
12
Step-by-step explanation:
there are 41 people and u only have 29. that means 12 won't get so u will ask for 12 more
5 out of 6 is the chances NOT to roll a 5.
Approximately 83.33% of a chance to NOT roll a 5.

x = 108
y = 36
z = 72
=============================================================
Explanation:
Check out the diagram below. I have added letters of x, y and z in places to help find the values of y and z. Note the triangle on top is isosceles (since a regular polygon has all sides equal; therefore the triangle on top has the top diagonal sides equal).
Before we find either y or z, let's find x.
For any regular polygon, the interior angles are all the same measure. They sum to 180(n-2). In this case, n = 5, so the angles sum to 180(5-2) = 540. Each individual interior angle is 540/n = 540/5 = 108 degrees
x = 108
Another way to find this interior angle is to first find the exterior angle. For any convex polygon (regular or not), the exterior angles always add to 360. When we talk about regular polygons, each individual exterior angle is 360/n. So in this case, we have 360/5 = 72 as one exterior angle. The adjacent interior angle is therefore x = 180-72 = 108. So there are two ways to find the measure of an interior angle.
--------
Referring to the diagram, specifically the isosceles triangle on top, we can see that it has angles of x, y and y. They add to x+y+y = x+2y. Set this equal to 180, plug in x = 108 and solve for y
x+2y = 180
108+2y = 180
2y = 180-108
2y = 72
y = 72/2
y = 36
--------
The bottom most triangle is a congruent copy of the triangle on top. We have another isosceles triangle with the same side lengths as before. This triangle also has x, y and y as mentioned above.
Notice the adjacent angles of y and z in the bottom left corner. They must add to 108 as this was the measure of the interior angle of a regular pentagon. So,
y+z = x
36+z = 108
z = 108-36
z = 72
