Answer:

{27}^{ \frac{1}{3} }  <    {125} ^{ \frac{2}{3} }  <  {9}^{ \frac{3}{2} }

Step-by-step explanation:

{9}^{ \frac{3}{2} }  =  \sqrt[2]{ {9}^{3} }  =  \sqrt[2]{ {3}^{6} }  =  { 3}^{3}  \\  {27}^{ \frac{1}{3} }  =  \sqrt[3]{27}  =  \sqrt[ 3]{ {3}^{3} }  = 3 \\  {9}^{ \frac{3}{2} }   > {27}^{ \frac{1}{ 3} }  \\  \\  {125}^{ \frac{2}{3} }  =  \sqrt[3]{ {125}^{2} }  =  \sqrt[3]{ {5}^{6} }  = 25 \\  \\ 3 < 25  <  {3}^{3}  \\  {27}^{ \frac{1}{3} }  <    {125} ^{ \frac{2}{3} }  <  {9}^{ \frac{3}{2} }

Answer:

Step-by-step explanation:

9^{\frac{3}{2} } = ( √9 )³ = 27

27^{\frac{1}{3} } = ∛27 = 3

125^{\frac{2}{3} } = ( ∛125 )² = 25

27^{\frac{1}{3} } , 125^{\frac{2}{3} } , 9^{\frac{3}{2} }

Aaron is in his math class. His teacher says that class will be dismissed when the minute hand makes a 90° clockwise rotation. W
olga_2 [115]

Answer:

3:20

Step-by-step explanation:

The 360 degrees clockwise rotation of the minute hand corresponds to 60 minutes.

The 90 degrees clockwise rotation is one-fourth of the 360 degrees, and hence will corresponds to 15 minutes.

The time is now 3:05.

After 15 minutes the time will be 3:20

Therefore the teacher dismisses the class at 3:20

Solve to find the values of a and b.<br>4a + 7b = 38<br>9a + 7b = 68​
Nataliya [291]
4a + 7b = 38 -> (1)
9a + 7b = 68 -> (2)

Subtract (1) from (2),
9a - 4a + 7b - 7b = 68 - 38
5a = 30
a = 6

HELP NEED NOW, WILL GIVE BRAINLIEST: The difference of measures between the arcs subtended by chord AB is 160°. Line l is tangen
omeli [17]

Answer:

  50°

Step-by-step explanation:

As usual, the diagram is not drawn to scale.

The chord divides the circle into two arcs that have a sum of 360°. If we let "a" represent the measure of the smaller arc, then we have ...

  a + (a+160°) = 360°

  2a = 200° . . . . . . . . . . . subtract 160°

  a = 100°

The measure of the angle at A is 1/2 the measure of the subtended arc:

  acute ∠A = a/2 = (1/2)·100° = 50°

_____

<em>Comment on this geometry</em>

Consider a different inscribed angle, one with vertex V on the circle and subtending the same short arc subtended by chord AB. Then you know that the angle at V is half the measure of arc AB. This is still true as point V approaches (and becomes) point A on the circle. When V becomes A, segment VA becomes tangent line <em>l</em>, and you have the geometry shown here.
