In a hypothetical situation, it would take fifty megaTNT to completely decimate the Earth into pieces. Saturn would take fifty times the amount of megaTNT to blow up that the Earth does, and the sun would need one hundred times the amount of megaTNT that Saturn does. How much megaTNT is needed to completely explode the sun? pls help this is confusing to me

250,000 megaTNT

Step-by-step explanation:

We start with the Earth needing 50 megaTNT to explode. Saturn needs 50x this amount. That’s 2500 megaTNT. The sun needs 100x the amount that Saturn does, which is 2500. 2500 x 100 is 250,000.

both equations and proportions are better.

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!
