Answer:
2500÷$3.21 =778.81
just round to the nearest whole number
Answer:
$44.45
Step-by-step explanation:
Convert 15 2/5% to decimal, =0.154
38.52+(38.52x0.154) (do this to add the cost of the % increase)
≈$44.45.
Because if there is no more supplies for the sale, the sale can't apply to nothing!
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
Answer:
Step-by-step explanation:
Perimeter is equal to twice the length plus twice the width
Perimeter = 2L + 2W factoring out the 2
Perimeter = 2(L + W) L = (8x + 5 - 3x) W = (4x - 1)
first I would simplify L collecting the terms of x
L = (5x + 5)
plug in to L and W
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 )) L = (8x + 5 - 3x) W = (4x - 1)
Perimeter = 2 ( 5x + 4x + 5 -1 ) collect like terms
Perimeter = 2 ( 9x +4) 2 times the 9 and 4
Perimeter = 18x + 8 SOLVE for x
Perimeter - 8 = 18x + 8 -8
Perimeter - 8 = 18x
(Perimeter - 8) / 18 = 18x / 18
(Perimeter - 8) / 18 = x
remember the Perimeter equals 88
(88 - 8) / 18 = x units
4.444444444 units = x
This seems like an odd number so let's it
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 ))
Perimeter = 2 (( 5(4.444) + 5 ) + ( 4(4.444) - 1 )) = 87.9952
close enough with the rounding off error
