For Phone - 600 x 0.1 = $60
For Internet = 600 x 0.25 = $150
For Utilities = 600 x 0.6 = $360
360 + 150 + 60 = $570
600 - 570 = $30
Answer: $30
Initial balance : 463.76
refunds : 12.56 + 52.11 + 26.03 = 90.70
sales : 101.32 + 10.98 = 112.30
463.76 - 90.70 + 112.30 = 485.36 is the correct balance
so there is a (511.39 - 485.36) = 26.03 difference
so the mistake made was instead of subtracting the 26.03 refund, she added it as a sale
<span>343 pi in^3 ; exact volume
1078 in^3 ; Approximate volume
Since it's not specified, I will assume the axis of rotation will be one edge of the square. With that in mind, here's the solution.
Since the shape specified is a square with an area of 49 in^2, the length of any edge will be sqrt(49) = 7 inches.
Since we're rotating along one edge, we will create a cylinder with a radius of 7 inches and a height of 7 inches. The volume will be the area of a circle with a 7 inch radius multiplied by the height of the cylinder. So
V = pi*h*r^2
V = pi*7*7^2
V = pi*7*49
V = pi*343
V = 343pi
V = 1077.56628; approximately.
So the exact volume is 343pi in^3 and an approximate volume is 1078 in^3</span>
Answer:
14
Step-by-step explanation:
To find the perimeter of a rectangle, you need to find the sum of 2 times the width and the height. 2*3+2*4=6+8=14 feet. Hope this helps!
Simplify -45/6 to -15/2, and your answer as a decimal will be -7.5.
