Answer:
Step-by-step explanation:
Area = Length times Width
5 1/4 times 3 3/4
5 x 4 + 1 = 21
21/4
3 x 4 +3 = 15
15/4
21/4 x 15/4 = 315 / 16 or 19 11/16 ft^2
Answer:
19 11/16 or 315/16
Steps:
Turn the fractions into an improper fraction and then multiply straight across
5 1/4 = 21/4
3 3/4 = 15/4
(21/4)*(15/4)= 315/16= 19 11/16
Yes you got it right :)

The appropriate choice is
A. (-4.5, 4.25)
Answer:
165 ways
Step-by-step explanation:
Selection deals with combination
There are a total of 11 from which 3 are to be selected
11C3 = 11!/3!(11-3)!
= 11!/(3!x8!)
=(11x10x9x8!)/(3x2x8!)
=11x10x9/6
=11x5x3 = 165 ways
Ok slot method
3 slots
1st slot has 52 options
2nd slot has 51 optoins (1 went to first slot)
3rd slot has 50 options (1 went to previous slot)
number of ways=52*51*50=132600 ways
I think it is F, but I am a not sure.
Substitue what y equals for y and solve.
Hope this helps.
