Answer:
(i)= 45 KPH, (ii) = 251 miles
Step-by-step explanation:
'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.
Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.
I agree with the answer being B because since it's a common ratio you could just multiply -1/4 with -2 and keep doing that with each new term
Check the picture below.
so the area of the hexagon is really just the area of two isosceles trapezoids.

Answer:
The answer is option (C), T = 100 • 0.1 • 10
Step-by-step explanation:
Total interest (T) earned after a 10 years can be expressed as;
Total interest (T)=Principal amount×interest rate×Number of years
where;
Total interest=T
Principal amount=$100
Interest rate=10%=10/100=0.1
Replacing;
T=100×0.1×10
The equation for calculating the total interest amount after 10 years can be written as;
T = 100 • 0.1 • 10
