(1/3) cubed, since the equation for the volume of a cube is an edge, cubed
Answer:
x> 2
Step-by-step explanation:
Multiply by 6
2x6=12
5x+2>12
Move the 2 and make it subtraction
5x>12-2
Subtract 12-2=10
5x>10 divide by 5
X>2
Answer:
91+c
Step-by-step explanation:
The equation to find the perimeter of the triagle is every side added together. We know 2 sides which means we add them to get 91. Then we know we don't know the next number but we add it so we just put the c where the next number to be added would go.
Answer:
252pi (B)
Step-by-step explanation:
Find the area of the bases (2 * pi * r^2)
r = 6, so:
72pi = total area of bases
Find the area of the side (pi * 2 * r * h)
r = 6 and 15 = h, so:
180 pi = area of the side
180pi + 72pi = 252pi (B)
Answer:
9%
Step-by-step explanation:
Let the required number be 100.
Now, according to the question, the number is first increased by 30 %
⇒ 100 + 30 % of 100
⇒ 100 + [(30*100)/100]
⇒ 100 + 30
⇒ 130
Then, it is decreased by 30 %
⇒ 130 - (30 % of 130)
⇒ 130 - [(30*130)/100]
⇒ 130 - 39
⇒ 91
Net Decrease = 100 - 91
= 9
Percent Decrease = (Change in number*100)/100
⇒ (9*100)/100
= 9 %
