Answer:
Total money made is $597, $489 from hardbacks and $108 from paperbacks.
Step-by-step explanation:
$3 x 163= $489
$2 x 54= $108
total $= 3(163)+2(54)
total $= 489 + 108
total $ = 597
Answer:
20
Step-by-step explanation:
- x+20%=24
- x+x*20/100=24
- x+0.2x=24
- 1.2x=24
- x=24/1.2
- x=20
Step-by-step explanation:
So you would need to find a common denominator to add the fractions together first, and the closest would be 40
5/8 turns into 25/40 because we times the bottom and the top by 5 to get the LCD (least common denominator)
6/10 turns into 24/40 when times by 4 for the LCD of 40
Then add them together: 25/40 + 24/40 = 49/40
And since 1 could also be written as 40/40 since that is the whole number, this means the following expression is true.
49/40 > 40/40 (or 1)
The face dimensions are all the same, so the 3 lateral faces each have the same area. The lateral area is
3·(10 cm²) = 30 cm²
