Area of the four walls = 2(Length x height) + 2(Width x height)
Area of the four walls = 2(21 x 28) + 2(13 x 28)
Area of the four walls = 1176 + 728
Area of the four walls = 1904 in²
----------------------------------------------------------------------------
Answer: Total area of the 4 walls = 1904 in²

This answer maybe long, but it includes all the essential steps to make it easy
This problem shows that the fraction of the time worked by three individuals need to be = to one person working full time.
It just means that the fractions need to add up to one. Since we got to know that one person works 1/2 the time on the project and the other works 1/3 of the time, let us use a variable to represent the amount of time the last person needs to work to have a total of 1.
This is quite easy:
variable = t(representative of the last person)
step 1: 1=1/2+1/3+t
step 2: keep the variable alone at one side
1-1/2-1/3=t
this step on a calculator will be easy, but dont have a calculator? Thats fine!
Lets have a common denominator
2 and 3 can be 6
1/1*(6/6)-1/2*(3/3)-1/3*(2/2)=t
6/6-3/6-2/6=t
step 3: just subtracts and get the answer
1/6=t
In conclusion, the third person must be working 1/6 the time on the project
The final price is $135 , because
.10 × 150 = 15
150 - 15 = 135
So the answer would be x=1 and y=-2. Hope this helps
Answer:
5
Step-by-step explanation:
Given:
- Daily pass = $77
- Season ski pass = $450
- Skis = 20
77 + 20 = 97
450 + 20 = 470
Keep multiplying 97 with random numbers until it passes 470.
97 × 4 = 388
97 × 5 = 485
So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.
Hope this helped.
