and it has the nearest tenth value is 126
Answer:
$142.03
Step-by-step explanation:
123.50 x 0.15 = 18.53
123.50 + 18.53 = 142.03
Answer:
Step-by-step explanation:
Perimeter of a polygon = Sum of all sides of the polygon
Perimeter of the given rectangle = 2[(5x - 2) + (3x - 0.5)]
= 2[8x - 2.5]
= (16x - 5)
Perimeter of the given triangle = (2x + 3) + (2x + 3) + (10x - 5)
= 14x + 1
Since perimeter of the rectangle and triangle are same, equation will be
(16x - 5) = (14x + 1)
16x - 14x = 5 + 1
2x = 6
x = 3
Perimeter = (16x - 5)
= 48 - 5
= 43 units
3,540 grams of ash
If its density is 2.75 g/cc and
density = mass / volume then its volume is
volume = mass / density
volume = 3,540 g / 2.75 g / cc
volume =

1287.272727 cc
So, rounded it is 1,287.3 cubic centimeters but to keep the same number of significant figures, the volume is
