Answer:

1) \:   {b}^{5}

2) \:  \:  + 16 {m}^{9}

Step-by-step explanation:

{b}^{3}  \times  {b}^{2}  =  {b}^{3 + 2}  =  {b}^{5}

we know that

( - ) \times( - ) = ( + )

So

- 2 {m}^{4}  \times  - 8 {m}^{5}  \\  =  + 16 {m}^{9}

JK is tangent to a circle with centre H as shown below. What is HK ?<br> 8 mi<br> 15 mi
sashaice [31]

Given:

JK is tangent to a circle with center H

To find:

The length of HK.

Solution:

The image is attached below.

JK = 8 mi, HJ = 15 mi

JK is tangent to a circle.

The tangent is always perpendicular to the radius.

Therefore, m∠J = 90°

Using Pythagoras theorem:

HK² = JK² + HJ²

HK² = 8² + 15²

HK² = 64 + 225

HK² = 289

HK² = 17²

Taking square root on both sides.

HK = 17

The length of HK is 17 mi.

The ratio of tickets sold to see the incredible musical wicked to tickets sold to see Cats is 11 to 7 if there were 2700 total t
tia_tia [17]
Use algebra to set up 2 equations.

Assign c as number of tickets for CATS and w for number of tickets of WICKED

c + w = 2700

c / w = 7 / 11

Then solve for one of them in the first equation

c = 2700 - w

Then put this value for c into the 2nd equation

(2700 - w) / w = 7 / 11

Now cross multiply the numerator by denominator of both numerator and denominator pairs

7w = 11 x (2700 - w)
7w = 29700 - 11w

Now solve for w

7w = 26700 - 11w

Add +11w to both sides

18w = 29700

Now divide by 18 on both sides

w = 1650

Then c is the remainder of that ... 2700 - 1650 = 1050

You can also check because 7 / 11 = 1050 / 1650
