Answer:
22 feet
Step-by-step explanation:
Given
- In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
- The actual length(L)=7 feet
To find the actual perimeter, we need the breadth of balcony(B)
The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth
⇒
Therefore Breadth actually=4 feet
⇒Perimeter
Therefore perimeter of rectangular balcony= 22 feet
Answer:
I bedroom condo = $280
2 bedroom condo = $400
3 bedroom condo = $560
Step-by-step explanation:
Given that :
Total rental cost for all 3 condos = $1240
Let :
I bedroom condo = b
2 bedroom condo = c
3 bedroom condo = 2b
Hence,
b + c + 2b = 1240
3b + c = 1240 - - - (1)
REPAIR COST :
Total repair cost = $276
1 bedroom = 10% of b = 0.1b
2 bedroom = 20% of c = 0.2c
3 bedroom = 30% of 2b = 0.3 * 2b = 0.6b
Hence,
0.1b + 0.2c + 0.6b = 276
0.7b + 0.2c = 276 - - - (2)
From (2)
0.7b + 0.2c = 276
0.7b = 276 - 0.2c
b = (276 - 0.2c) / 0.7
Substitute b = (276 - 0.2c) / 0.7 into (1)
3(276/0.7 - 0.2c/0.7) + c = 1240
1182.8571 - 0.8571428c + c = 1240
1182.8571 + 0.1428571c = 1240
0.1428571c = 1240 - 1182.8571
0.1428571c = 57.1429
c = 57.1429 / 0.1428571
c = 400
3b + c = 1240
3b + 400 = 1240
3b = 1240 - 400
3b = 840
b = 840/3
b = 280
Hence,
I bedroom condo = $280
2 bedroom condo = $400
3 bedroom condo = 2(280) = $560
Answer:
the sample proportion is higher
Step-by-step explanation:
What we must do is calculate the proportion of the population, we are left with the fact that out of 38 students 58% have cell phones, these are the proportion of the population, then they would be:
38 * 58% = 22.04 students
Now, the sample proportion is 24.
Therefore 22.04 < 24
Which means the sample proportion is higher
