Answer:
10
Step-by-step explanation:
1 of 5 sections is yellow. So the expected number of times the spinner lands on yellow is:
(1/5) (50) = 10
The answer that is NOT the formula for an area of a rectangle is A= 1/2X h X (Base 1 + Base 2)
Willy can cover in 1L paint

- 1st box should be filled with 4.5
Can cover in 10L

Second one should be filled with 45
2(4x - 5) = 49
8x - 10 = 49
8x - 10 + 10 = 49 + 10
8x = 59
8x/8 = 59/8
x = 7.375
The final price of the item is $22,644
The initial discount of 10% leaves the price at 90% of the retail value:

cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:

cross multiply to solve for x:
100x = 2,264,400
x = 22,644
The final price of the home entertainment system is $22,644
