Answer:

62°

Step-by-step explanation:

Given that the triangle has two angle measures of 41° and 77°.

All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:

Let x = the missing measure

[tex]41 + 77 + x = 180[/tex]

Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: [tex]118 + x = 180[/tex]

Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: [tex]x = 62[/tex]

Therefore, the third angle must have a measure of 62°.

Answer:

  16.32 N11.38°E km/h

Step-by-step explanation:

16.0∠0° +3.22∠90° ⇒ (x, y) = (3.22, 16.0) ⇒ (r, θ) =

(3.22, 16.0) ⇒ (r, θ) = (√(3.22² +16²), arctan(3.22/16)*) = (16.32, 11.38°)

The woman's velocity is 16.32 km/h in a direction that is 11.38° east of north.

_____

This is her velocity in any stationary frame of reference.

____

* We have used North as the reference for the angle, measured CW.

Answer:

  -2 ≤ x < 12

Step-by-step explanation:

-15x +4 ≤ 34

Add 15x-34 to both sides

  -30 ≤ 15x

Divide by 15

  -2 ≤ x

__

-6x +70 > -2

Add 6x +2 to both sides

  72 > 6x

Divide by 6

  12 > x

__

The two solution spaces overlap. Since the AND of the two inequalities is involved, the solution of both is just that part of the number line where there is overlap.

The solution is ...

  -2 ≤ x < 12

Answer:

46 minutes

Step-by-step explanation:

Teresa purchased a prepaid phone for $15

Long distance calls cost 24 cents a minute using this card

She used the card just once to make a long distance call

The remaining credit on her card was $3.96

Therefore the minutes in which her call lasted can be calculated as follows

Let x represent the minutes

15 - 24/100x= 3.96

15-0.24x= 3.96

-0.24x= 3.96-15

-0.24x= -11.04

x= 11.04/0.24

x = 46

Hence Teresa call lasted for 46 minutes

Answer:

2

Step-by-step explanation:

-2x+y=-7

Take the -2x and put it on the other side of the equation by changing the sign

y=-7+2x

Now put it in y intecpet form by putting the 2x first

y=2x-7

Slope is the number before the x.

so 2

Now knowing that parallel lines always have the same slope the answer is 2

Answer:

n = -.55

Step-by-step explanation:

8n + 4(1+5n) = -6n -14

8n + 5+20n = -6n -14

28n + 5 = -6n -14

34n + 5 = -14

34n = -19

n = -.55

Answer:

An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being  produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.

They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.

An echo is an unpleasant sound heard after a produced sound got reflected from a plain surface. It is majorly eliminated in a cinema theater by:

Echo is a sound produced due to the reflection of a produced sound by a plain surface. Its continuous occurrence leads to reverberation. It causes distortion of produced sound which makes it unpleasant to hearing. Thus the need for a mechanism which would reduce it to a bearable level.

To reduce or eliminate echo, the walls of the cinema theater had been constructed with sound absorbing materials which may include special pads. These would have been incorporated into the walls, and would absorb most unwanted sounds produced in the theater.

Also the cloths worn by viewers absorbs some of the unwanted sound, thus assisting to indirectly reduce echo.

Answer:

What do you mean?

Step-by-step explanation:

Answer:

Step-by-step explanation:

 x - 3y = 5

2x +  y = 10  multiply by 3 to eliminate y and solve for x

 x - 3y = 5

6x + 3y = 30  then add

7x          = 35

simplify:

x = 35 / 7

x = 5  

substitute x = 5 back into the eq.2

 2x +  y = 10

2(5) +  y = 10

           y = 10 - 10

           y = 0

therefore the answer is ( 5, 0 )

Step-by-step explanation:

cancel the 1 and add 18+4=22

Answer:

-1

Step-by-step explanation:

2y+6=1 -3y

add three to both sides and minus 6 from both sides becasue you want to get y by itself

5y=-5

now both sides by 5

y=-1

Answer:

y=−1

Step-by-step explanation:

2y+6=1−3y

Step 1: Simplify both sides of the equation.

2y+6=1−3y

2y+6=1+−3y

2y+6=−3y+1

Step 2: Add 3y to both sides.

2y+6+3y=−3y+1+3y

5y+6=1

Step 3: Subtract 6 from both sides.

5y+6−6=1−6

5y=−5

Step 4: Divide both sides by 5.

y=−1

Answer:

Step-by-step explanation:

The signs of the terms are + - - +. There are two sign changes, so 0 or 2 positive real roots.

Negating the signs of the odd-degree terms, the signs are + + + +. There are no sign changes, so 0 negative real roots.

For x=0, the value of the quartic is +3. For x=1, the value is -3, so we know there are 2 positive real roots, one of which lies in the interval (0, 1).

The 4th-degree polynomial equation must have 4 roots, so the other two must be complex.
