Step-by-step explanation:

In ANOP, NP is extended through point P to point Q,
mZOPQ = (6x – 15)°, mZPNO = (2x + 18)°, and
mZNOP = (2x – 13). What is the value of x?

Answers

Answer:

x = 10

Step-by-step explanation:

Form the information given, we can deduce that:

m<OPQ is an exterior angle of ∆NOP = (6x - 15)°

m<PNO = (2x + 18)° and m<NOP = (2x - 13)° are both interior angles that are opposite to the exterior angle.

Therefore, based on the exterior angle theorem:

m<OPQ = m<PNO + m<NOP

(6x - 15)° = (2x + 18)° + (2x - 13)°

Solve for x

6x - 15 = 2x + 18 + 2x - 13

6x - 15 = 4x + 5

6x - 15 - 4x = 4x + 5 - 4x (Subtraction property of equality)

2x - 15 = 5

2x - 15 + 15 = 5 + 15 (addition property of equality)

2x = 20

2x/2 = 20/2 (division property of equality)

x = 10

Choose the equation and the inequality needed to answer this question. Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He is going to work 15 hours this week. At least how many hours does he need to tutor to make more than $180? Let x equal the number of hours he tutors and y be the number of hours he scoops ice cream.

Answers

Answer:

One second let me look it up for u :)

Step-by-step explanation:

Answer:

Total number of hours = 15

Let the hours spent tutoring french be x.

Therefore hours spent on scooping ice cream = (15 - x)

Amount:    Tutoring french is $15 an hour, total for x hours = 15x

For scooping ice cream  it is $10 an hour   10*(15 - x) = 150 - 10x  

To make more than $180

15x  + (150 - 10x)  > 180

15x + 150 - 10x > 180

15x - 10x > 180 - 150

5x > 30

x > 30/5

x > 6

trevor needs to tutor 6 hours to make more than 180

In a hotel, Elevator 1 stops at the third floor at an elevation of 40ft. Elevator 2 stops at the parking level at an elevation of -25ft.

How far apart, in feet, are the two elevators? Show or explain your work.

PLEASEEE ANSWER!!!

Answers

Answer:

65 ft

Step-by-step explanation:

Negative and positive numbers can be expressed as how far away they are from zero.

40 is 40 units away from zero. Elevator 1 is 40 units from 0.

-25 is 25 units away from zero. Elevator 2 is 25 units from 0.

To find the distance, we'll add their distances from 0.

40 + 25 = 65

They are 65 units apart. In your problem you specify feet, so they are 50 ft apart.

Point P is the centroid of LMN. Find PN

Answers

Answer:

PN = 14

QP = 7

Step-by-step explanation:

Extend PQ to R so that QR=PQ

MQ = QL  (known, mid-point)

MPLR is parallelogram (diagonal bisect each other)

MP // RL          NP/PR = NE/EL = 1/1 (E mid-point, known)

NP = PR

PQ = QR = 1/2 PR = 1/2 NP

NP = 2 PQ

NP + PQ = 2PQ + PQ = 3 PQ = QN = 21

PQ = 7

PN = 14

What is the measure of x

Answers

Answer:

x = 75°

Step-by-step explanation:

From the figure it appears that:

[tex] m\angle B = 36\degree [/tex]

and

[tex] m\angle D = 39\degree [/tex]

x is the measure of the exterior angle of [tex] \triangle BDH[/tex]

Therefore, by exterior angle theorem:

[tex] x = m\angle B+ m\angle D [/tex]

[tex] x = 36\degree+ 39\degree [/tex]

[tex] x =75\degree [/tex]

Write the negation of the proposition.

Some people don't like walking.

Answers

Answer: All people do like walking

It might be more grammatically correct to say "all people like walking", but I wanted to include the "do" in there because we can see how the "don't" flips to "do". The "some" flips to "all" as well.

The negation of a statement is the complete opposite in every way. If a friend makes a claim that some people don't like walking, and you can prove that all people do like walking, then this contradicts your friend. The same can be said in reverse: if your friend claims "all people do like walking", then you can counter back with "some people don't like walking". All it takes is one counter-example to prove the claim "some people don't like walking" to be correct. In terms of logic, the word "some" means "one or more".
