Answer:
A) 29/40
Step-by-step explanation:
The formula for this is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, you have ...
P(A or B) = 9/20 +1/2 - 9/40
P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40
P(A or B) = 29/40 . . . . matches choice A
Because 17 37/50 is a mixed fraction, we must convert it into an improper fraction:




To make dividing the fraction easier, we can multiply the numerator and denominator by 2:

Now it's easier to divide the numerator by the denominator:

17 37/50 converted into a decimal is
17.74.
The answer would be 17/12
Answer:
never, it will always be x²+6x+9
Step-by-step explanation:
if you expand (x+3)² you will always get:
x² + 3x + 3x + 9, which simplifies to x² + 6x + 9
Answer:
INCORRECT
Step-by-step explanation:
Given a rectangular prism,
Total Surface Area = 2(LW+LH+WH)
If Length = 12, Width =20, and; Height = 16.
Total Surface Area = 2(12*20+12*16+20*16)
=2(240+192+320)
=2(752)
=1504
The Surface Area is 1504 Square Units, therefore if someone says the surface Area is 3,840, they are incorrect!
