Answer:
1) A 1 1/3 2) C 1 5/12
Step-by-step explanation:
1) 2/6+4/8+5/10
Reduce 4/8 with 4 and 5/10 with 5.
2/6+1/2+1/2
Reduce 2/6 with 2.
1/3+1/2+1/2
Add fractions with a common denominator.
1/3+2/2
Reduce 2/2 with 1
1/3+1
Write all numerators above the common denominator.
1+3/3
Calculate.
4/3 = 1 1/3
2) 2 3/4 - 1 1/3
Change to improper fractions.
11/4 - 4/3
Write all numerators above the common denominator.
33-16/12
Calculate.
17/12 = 1 5/12
Hope this helps :)
23. You are expected to be familiar with the relationship
... cost + markup = selling price
a) cost + $23.99 = $119.95
... cost = $119.95 -23.99 = $95.96
b) The markup as a fraction of cost is
... markup/cost = $23.99/$95.96 = 0.25 = 25%
c) cost + markup = selling price . . . . the equation we started with
... cost/cost + markup/cost = (selling price)/cost . . . . divide by cost
... 100% + 25% = (selling price)/cost = 125%
25.
a) See part c) of problem 23. Selling price is 126% of cost.
b) Selling price = $450 × 1.26 = $567
c) Markup = $450 × 0.26 = $117
For this case we have that by definition, the perimeter of a rectangle is given by:
Where:
l: It is the length of the rectangle
w: It is the width of the rectangle
According to the image we have:
So, rewriting the perimeter expression we have:
Applying distributive property to the terms within parentheses we have:
Answer:
The perimeter of the rectangle is:
