Sam and bethan share £54 in the ratio 5: 4 work out how much each person gets.

Add the ratios together:

5 +4 = 9

Divide the total amount by t his number:

54 / 9 = 6

Now multiply each side of the ratio by 6:

Sam = 5 x 6 = £30

Bethan = 4 x 6 = £24

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
