Answer:
388,800 ft^2.
Step-by-step explanation:
Scale = 1 : 180
Actual length, Ls = 180 × 4
= 720 ft
Actual width, Bs = 180 × 3
= 540 ft
Area of a rectangle = Ls × Bs
= 540 × 720
= 388,800 ft^2.
Answer:
0.025
Step-by-step explanation:
-This is a conditional probability problem.
-Let L denote lens defect and C charging defect.
#We first calculate the probability of a camera having a lens defect;

#Calculate the probability of a camera having a charging defect:

The the probability that a camera has a lens defect given that it has a charging defect is calculated as:

Hence, the probability that a camera has a lens defect given that it has a charging defect is 0.025
Answer:
Barry has to pay back $1150
Step-by-step explanation:
We can set up an equation to help solve this problem
x is the amount he has to pay back
x=1000+3(1000/20)
1000/20 lets us know how many times he borrowed 20 dollars
x=1000+3(50)
x=1000+150
x=1150
Barry has to pay back $1150
