Answer:

$x^{15}$

Step-by-step explanation:

Distribute the ^3 on top

(27 $x^{6}$ $y^{-9}$ )

distribute the ^ -9 on bottom, only to what is in the parenthesis

(27 $x^{-9}$ $y^{-9}$ )

the 27's cross out, the $y^{-9}$ 's cross out

$x^{6}$ / $x^{-9}$ is left

move the $x^{-9}$ to the top of fraction to change its sign

$x^{6}$ · $x^{9}$ = $x^{15}$

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?

makkiz [27]

Answer:

118°

Step-by-step explanation:

When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.

Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.

Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.

(5x + 17) + (15x - 17) = 180

5x + 15x + 17 - 17 = 180

20x = 180

20x/20 = 180/20

x = 9°

Nkw let's substitute x = 9 into the equations

5x + 17 =

5(9) + 17 =

= 62°

15x - 17 =

15(9) - 17 =

= 118°

Both equations should add up to be 180°.

Therefore the measure of the largest angle is 118°.

Does anyone know the 4 answers

Naya [18.7K]

Yes, you can divide $5 by 2. There are 100 cense in a dollar, 500 in five dollars, if you divide 500 by 2 you get 250 cense, with each 100 cense equaling $1. You would have $2.50.

Also, you got number 5 wrong, it’s how far he’s gone, not how far he has left.

Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around

Alex777 [14]

One complete revolution of the minute hand sweeps a central angle of 360° which is equivalent to 60 minutes.
That is, the minute hand creates
(360°/(60 min) = 6 degrees/min.

From 3:35 to 3:55 is 20 minutes.
It sweeps a central angle of
(20 min)*(6 deg/min) = 120°

Because 360° = 2π radians,
120° = (120/360)*2π = (2π)/3 radians

Answer:
$\frac{2 \pi }{3} \,radians$
In decimals, this is 2.1 radians (nearest tenth)

Part 2:
Because the minute hand is 4 inches long, the length of the arc swept is
(4 in)*(2π/3 radians) = 8π/3 inches

Answer:
$\frac{8 \pi }{3} \,inches$
In decimals, this is 8.4 inches (nearest tenth).
