We can do this easily. Since we know that the numerator is more than the denominator, we need to know by how much.
39-28=11; It's only 11 more, which means 11/28 would be the fraction and the whole number is 1.
39/28= 1 11/28

Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
As a result of the price increase, an additional $188.50 was made.
The first step here is to find out the increased revenue that was earned on each bag of popcorn:
<em>= New price - old price </em>
= 3.75 - 3.10
= $0.65
The concession stand sold 290 units so the increased amount that was earned was:
<em>= Incremental revenue x Number of units sold </em>
= 0.65 x 290
= $188.50
In conclusion, an additional $188.50 was made.

Answer: Hello mate!
You have one $20 bill, two $10 bills, three $5 bills and four $1 bills in a bag.
This adds to a total of 10 bills in the bag, and you want to know the expected value if you took one at random.
The expected value is defined as ∑pₙxₙ
where pₙ is the probability for each event (in this case is the number of bills of a given price divided the number of bills in the bag) and xₙ is the value of the bill.
Then we can write the expected value as:
E = (1/10)*$20 + (2/10)*$10 + (3/10)*$5 + (4/10)*$1 = (1/10)( 20$ + 2*$10 + 3*$5 + 4*$1) = (1/10)*($59) = $5.90
The expected value is $5.90.
