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
Answer:
5: Permutation. 6: Combination
Step-by-step explanation:
Being that the team of Basketball players are <u>Arranging</u> who will change the water cooler, then the Answer is <u>Permutation</u>.
Mei has homework, and she's deciding which subject to do first. She has a <u>Selection</u> of choices, thus being the Answer- <u>Combination</u>.
Hope this makes sense. If you need clarification, feel free to reach back out to me.
Hello,
If you are starting with the angle of 40 degrees, you have an adjacent side and hypotenuse. Therefore, it is a cosine relationship.
We can write:
cos(40) = adj / hyp
cos(40) = x / 220
To solve for x, simply multiply 220 by the cos(40).
You can write it as: 220 cos(40)
Good luck,

40*39=79
Answer:
Step-by-step explanation:
C = 59.4
Fixed Cost (F) = 25
C = 25 + 0.4*x Solve for x
59.40 = 25 + 0.4x Subtract 25
34.4 = 0.4x Divide by .4
34.4/0.4 = x
x = 86 miles
