Answer:

57.1km/hour

Step-by-step explanation:

I will do this by calculating the total time and distance from Liverpool to Sheffield.

Liverpool to Manchester: 56/70 = 0.8 hours

Liverpool to Sheffield: 56+61=117km, 75mins=1.25 hours, 0.8+1.25=2.05hours

Speed=117km/2.05hours = 57.1km/hr (to nearest 1 decimal place)

Hope it helps! :)

Arithmetic sequence a1=8 d=9

Ugo [173]

Answer:

$\ \ \ \ \ \ a_n=8+9(n-1)\\\implies a_n=8+9n-9\\\implies a_n=9n-1$

Step-by-step explanation:

arithmetic sequence equation:

$a_n=a+(n-1)d$

where a is the first term and d is the common difference

Therefore,

$\ \ \ \ \ \ a_n=8+9(n-1)\\\implies a_n=8+9n-9\\\implies a_n=9n-1$

The length of a rectangular is 5/2 unites greater then twice its width if it’s width w which expression gives the perimeter of t

strojnjashka [21]

If width is w the length can be represented as 5/2+2w.

Formula for perimeter is 2l + 2w

So it would be 2w + 2(5/2 + 2w)

OR 2w + 5 + 4w

OR 6w + 5

See if this helps ;)
