Leona is comparing the cost of cell phone bills between two different companies. One option gives her unlimited data and texting for $40 a

month, but charges $0.25 per minute talking on the phone. The other plan

only charges $0.10 per minute talking on the phone, but charges $60 a

month for unlimited data and texting. How many minutes would she

spend talking on the phone for the plans to be the same price?

133 minutes

Step-by-step explanation:

Hi, to answer this question we have to write an equation for the cost of each company:

The cost is equal to the fixed fee (40) plus the product of the cost per minute talking on the phone (0.25) and the minutes spent talking in the phone in the month (m)

40 + 0.25 m

The cost is equal to the fixed fee (60) plus the product of the cost per minute talking on the phone (0.10) and the minutes spent talking on the phone in the month (m)

60+ 0.10m

40 + 0.25 m = 60+ 0.10m

Solving for m:

0.25m-0.10m = 60-40

0.15m = 20

m = 20/0.15

m= 133.34 minutes = 133 minutes (rounded)

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
