Five number are in the ratio 1:2:3:4:5 and the sum is 585.find the numbers

39, 78, 117, 156 and 195.

Step-by-step explanation:

If the lowest number is x then we can write the numbers as:

x, 2x, 3x, 4x and 5x, so:

x + 2x + 3x +  4x +  5x = 585

15x = 585

x = 39.

So the second number is 39 * 2 = 78

So all numbers are 39, 78, 117, 156 and 195.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
