Help How do you do this one?

Step-by-step explanation:

if two chords of a circle are at equal distance from the center then they are equal.

OP=OQ

AB=CD

AB=2PB=2(3x-17)=6x-34

because perpendicular from the center on a chord bisects the chord.

6x-34=15-x

6x+x=15+34

7x=49

x=7

AB=6×7-34=42-34=8

PB=3×7-17=21-17=4

Radius of circle=√(OP²+PB²)=√(3²+4²)=√(9+16)=√(25)=5

step-by-step explanation:

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!
