Answer:
The error in the argument is in assuming that the line from p to d passes through line ab - that is, that pd crosses below a. But actually pd passes above a. This means that the angle pad is not equal to x + pab, but rather angle pad = 360-(x+pab). The rest of the "proof" then falls apart.
Step-by-step explanation:
Answer:
5(a-b)=3(a+b)
5a-5b=3a+3b
2a-2b=0
2a=2b
a=b
a:b=1
Step-by-step explanation:
Answer:
$
Step-by-step explanation:
Use the compound-interest formula:

Where:
FV=Future value or the ending amount
PV=Present value or the initial amount=750
n=Number of compoundings in any one year=2
t=Total number of years=4
r=interest rate=0.0425
Now, replacing the data in the equation:
$
Answer: B is the answer
Step-by-step explanation:
Answer:
33.3%
Step-by-step explanation:
Given data
Cost of shoes= $60
Selling price = $100
% markup = (selling-cost/cost)*100
% markup = (100-75/75)*100
% markup = (25/75)*100
% markup = (0.33333333333)*100
% markup =33.3%
Hence the markup is 33.3%
