Answer:
Katrina will have to pay $21.02 this month.
Step-by-step explanation:
The cost per text message = $0.19
Last month credit = $9.50
The number of text messages sent this month = 158
So, the total cost of 158 texts = 158 x cost per text
= 158 x $0.19 = $ 30.52
So, her total bill = The amount spent on texts - The credit amount
= $ 30.52 - $9.50 = $21.02
So, Katrina will have to pay $21.02 this month.

Step-by-step explanation:
First term is initial number
Second term is one plus the percent as a decimal (if it’s an increase)
Then to the power of 4 assuming that there are 4 year in between 2016 and this year, 2020
Answer:
The statements that must be true are:
XY and JK form four right angles ⇒ B
XY ⊥ JK ⇒ C
JP = KP ⇒ E
m∠JPX = 90° ⇒ F
Step-by-step explanation:
From the given figure
∵ Line XY is the perpendicular bisector of the line segment JK
→ That means line XY is the line of symmetry of the line segment JK
∴ XY ⊥ JK ⇒ C
∵ XY ∩ JK at point P
∴ P is the midpoint of JK
∵ XY ⊥ JK
∴ ∠JPX, ∠KPX, ∠JPY, and ∠KPY are right angles
∴ XY and JK form four right angles ⇒ B
∵ The measure of the right angle is 90°
∴ m∠JPX = m∠KPX = m∠JPY = m∠KPY = 90°
∴ m∠JPX = 90° ⇒ F
∵ P is the midpoint of JK
∴ JP = KP ⇒ E
