Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
we have
assume
substitute
step 2
Find the area of the 3 blades
we know that
The area of the 3 blades represent a central angle of 60 degrees, so
its a 1/6 of the area of complete circle
step 3
Find the weight of the three blades together to the nearest gram
Answer:
y = 1500 - 63x. See the attached for a graph.
Step-by-step explanation:
Each withdrawal will total $63, which includes $60 cash and a $3 fee. Then x withdrawals will total 63x dollars. This amount is subtracted from the initial account balance of 1500 to give the amount remaining.
If y represents the account balance, the equation can be written as
... y = 1500 -63x
The graph will have a y-intercept of 1500, and a slope of -63.
