Answer:
a³-b³= (a-b)(a²+ab+ b²)
Step-by-step explanation:
(0.35x + 0.14 * 18) / y = 0.23
x + 18 = y
We are asked to solve for the surface area of the described figure in the problem. We can conclude that the given figure is a rectangular prism since it was being mentioned in the problem that the height is laid flat. Therefore, the formula for the surface area is SA = PH + 2B where "P" stands for the perimeter of the rectangle and "B" stands for the area of the rectangle while "H" is for the height.
Solving for P, we have it:
P = width + length + width + length
P = 10 + 5 + 10 + 5
P = 30 inches
Solving for B, we have it:
B = length * width
B = 10 * 5
B = 50 inches squared
Solving for the surface area, we have it:
SA = PH + 2B
SA = 30*7 + (2*50)
SA = 310 inches squared
The answer is 310 in2.
Answer:
40000 and 12.5% respectively
Step-by-step explanation:
soln:
given,
cost price(c.p)=320000
selling price(s.p)=280000
loss(l),loss percentage(l%)=?
we know,
l=c.p-s.p
or,l=320000-280000
•°•l=40000
now,
l%=l/c.p*100%
or,l%=40000/320000*100%
•°•l%=12.5%
108 kilometers is 108,000 meters
108,000 ÷ 60 = 1800 meters per minute
1800 ÷ 60 = 30
