answer
31.4 ft squared
explanation
the circumference of a circle is c = 2r * pi = d * pi
plug in 10 for d (diameter) and 3.14 for pi
c = 10 * 3.14
c = 31.4 ft squared
We know 445 employees take the train, and that 321 of these exclusively take the train. So 445 - 321 = 124 take both the train and bus.
Now, if
is the set of employees that take the bus and
the set of employees that take the train, then
where
is the number of employees belonging to a general set
.
So the probability that an employee takes either the bus or train is

Answer:
see below
Step-by-step explanation:
2 1/2+ 3 3/16 + 7/8
Get a common denominator of 16
2 8/16 + 3 3/16 + 14/16
5 25/16
5 + 16/16 + 9/16
6 9/16
Subtract this from 8 ft
8 - 6 9/16
Borrow 1 from 8 in the form of 16/16
7 16/16 - 6 9/16
1 7/16
b 1 7/16 - 1 1/3
The common denominator is 48
1 21/48 - 1 16/48
5/48
if A= 3x and B= x
your equation will look like: 3x + x = 200
combine like terms to get 4x = 200
then, divide each side by 4 to get x = 50
if x = 50, then patient B receives 50 mg. to find A, you can either subtract 50 from 200 or you can take 50 multiplied by 3. patient A receives 150 mg.
