MIKE IS CHOOSING A 3 LETTER PASSWORD FROM THE LETTERS A, B, C, AND D. THE PASSWORD CANNOT HAVE THE SAME LETTER REPEATED IN IT. H

e-lub [12.9K]

There are 4 possible letters to start with.

The pass word is 3 letters long.

The first letter can be A, B, C, D = 4 different letters.

The 2nd letter can be 4 - 1 = 3 letters ( Can't have repeats)

The 3rd letter can be 3-1 = 2 letters ( no repeats)

Number of possible passwords = 4 x 3 x 2 = 24

Find the area of the shaded region. Round the the nearest tenth.

Brums [2.3K]

Answer:

226.084 sq.m.

Step-by-step explanation:

Radius of circle = 18.6 cm

Area of sector = $\frac{\theta}{360^{\circ} }\pi r^2$

Area of sector = $\frac{123}{360} \times 3.14 \times (18.6)^2$

Area of sector = $371.157 m^2$

Area of triangle = $\frac{1}{2} \times a \times b \times Sin x$

a = OA = radius = 18.6 cm

b = OB = radius = 18.6 cm

x =123 °

Substitute the values in the formula

Area of triangle = $\frac{1}{2} \times 18.6 \times 18.6 \times Sin 123$

Area of triangle = $145.073 m^2$

So, Area of shaded region = Area of sector - Area of triangle

= $371.157 m^2-145.073 m^2$

= $226.084 m^2$

Hence the area of the shaded region is 226.084 sq.m.

What are the rules to solving equations by multiplying or dividing?

Andreas93 [3]

Answer:

In order to move a number that is multiplied or divided by the variable, make sure to inverse both sides! That means, if the number is multiplied, you divide it by both sides. If it's divided, you must multiply it by both side; steps so that you can apply them to harder equations.

Sorry if this didn't help! I hope it did though, good luck. <3
