The 5 people can seat in a row in 5! ways
But we need to exclude the ways <span>that ann and bob are seated next to each other which is = 4! * 2!
</span>
So, the number of <span>ways can ann, bob, chuck, don and ed be seated in a row such that ann and bob are not seated next to each other = 5! - 4! * 2! = 72
</span>
<span>=====================================================
</span>
<span>Another solution:
</span>
<span>If ann seated in one of the ends, the number of ways = 3*2
</span>
<span>If ann didn't seat in one of the ends , the number of ways = 2*3
</span>
So, the total number of <span>ways that can <span>ann, bob be seated = 3*2 + 2*3 = 12
</span></span>
The remaining persons can seat with a number of ways = 3! = 6
So, the total ways that the five persons can seat = 12*6 = 72
If the ground beef is in pounds, it would be 5.25 lbs of ground beef.
We would get this answer by converting 3/4 into a decimal, .75. Then we multiply .75 by 7 (the number of people).
((This is if the amount of ground beef is in pounds, I'm not sure what it would be if it wasn't))
Answer:
FRACTION FORM P=3/4
DECIMAL FORM P=0.75
Step-by-step explanation:
1)Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
2) simplify 21/20
3) 3 21
(— • (p + 1)) - —— = 0
5 20
4) 3 • (p + 1) 21
——————————— - —— = 0
5 20
5)calculate the least common multiple
6)left denominator is 5
7) right denominator is 20
8)so lcm is 20
9)calculate multipliers for both fractions
10) rewrite both into equivalent fractions
11) then multiply the numerator of each fraction
12)Add the two equivalent fractions which now have a common denominator
13)pull out the like factors
14)get rid of the denominator
15)the 20 cancels out on the left side
16)Add 3 to both sides of the equation :
4p = 3
17)Divide both sides of the equation by 4:
p = 3/4 = 0.750
