Answer:
A. 13%
Step-by-step explanation:
let's suppose there's 1000 bars of chocolate in general
70 % dark = 700 dark choco bars
30 % milk = 300 milk choco bars
20 % have nuts = 200 bars have nuts
80 % don't have nuts = 800 bars don't have nuts
if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts
200 bars in general have nuts, if only 70 dark chocolate bars have nuts,
200 - 70 = 130
130 = 13%
Answer:
C = 0.65x + 145
Step-by-step explanation:
Assume:
Number of miles = x
Annual maintenance = $145
Total reimbursement = C = $0.65*x + $145 = $0.65x + $145
Answer:
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
where
b1 and b2 are the parallel bases
h is the height of trapezoid (perpendicular distance between the two parallel bases)
In this problem the area is equal to
we have the coordinates
the formula to calculate the distance between two points is equal to
step 1
Find the distance AB
substitute in the formula
step 2
Find the distance BC
substitute in the formula
step 3
Find the distance AD
substitute in the formula
step 4
Find the area
substitute the values
