A combination lock like the one shown has three dials. Each of the dials has numbers ranging from 1 to 8. How many different combinations are possible with the lock?

512 combinations
343 combinations
24 combinations
48 combinations

Answers

Answer 1

Answer:

512.

Step-by-step explanation:

First there is 111, 222  ......   888.

There are 8 of these.

Then there are the number of ways you can arrange numbers when 2 of them are the same

= 8P3/2

= 168

Finally if all numbers are different the number of ways

= 8P3 = 336

Answer is 8 + 168 + 336

= 512.

The algebraic expression of the SUM is n²+2n. What is the common difference and first term

Answers

Answer:

see explanation

Step-by-step explanation:

substitute n = 1, 2 into the sum rule

1² + 2(1) = 1 + 2 = 3 , then

a₁ = 3

2² + 2(2) = 4 + 4 = 8 , then

a₁ + a₂ = 8

3 + a₂ = 8 ( subtract 3 from both sides )

a₂ = 5

then

common difference d = a₂ - a₁ = 5 - 3 = 2

First term is 3 and common difference = 2

What value of x makes this equation true?

Step-by-step explanation:

[tex]5x+3 = 2x -3 \\\\\implies 5x -2x = -3 -3\\\\\implies 3x = -6\\\\\implies x = -\dfrac 63 =-2[/tex]

hello!

Let's solve this equation.

Step 1

Move the numbers to the right:-

5x=2x-3-3

Step 2

Move the x's to the left

5x-2x=-3-3

Notice I use the opposite operation :)

Step 3

Combine like terms

3x=-6x

Step 4

Divide both sides by 3

x=-2

That's the value of x that makes the equation true.

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.

Answers

Answer:

Step-by-step explanation:

The total shaded area = area of the square - area of a circle

= 9^2 - π * 4.5^2

= 17.3827

The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)

Perimeter:

The perimeter of the top shaded part

= AB + 1/2 circmference of the circle

= 9 + 1/2 * 2 π r

= 9 + 14.137

= 23.14 units ( to nearest hundredth)

The bottom part has the same perimeter.

Answer:

area: 17.38 cm²perimeter: 46.27 cm

Step-by-step explanation:

You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.

Area

The shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...

  A = s² -  π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square

  A = (9 cm)²(1 -π/4) ≈ 17.38 cm²

The area is about 17.38 cm².

Perimeter

The perimeter is the circumference of the circle plus two sides of the square.

  P = C +2s

  P = πs +2s = s(π+2)

  P = (9 cm)(π+2) ≈ 46.27 cm

The perimeter is about 46.27 cm.

Answers

Answer:

23.3786

Step-by-step explanation:

tan33° = x÷36

x = tan33°×36

x = 23.3786

Answer:

23.36

Step-by-step explanation:

We have three things on the diagram :

Angle = 33°Length of adjacent side = 36Length of opposing side = x

When the opposing side length and adjacent side length is given, always use the tan ratio.

tan = opposite / adjacent

First, find the numerical value of tan(33°)

tan(33°) = 0.6494 = 0.649

Solving :

tan(33°) = x/36 = 0.649⇒ x = 0.649 x 36⇒ x = 23.364 = 23.36

Answers

Answer:

Explanation:

area of circle: πr²                  ["r" denotes radius]

diameter: 2r

Given,

diameter: 4x

radius: 4x/2 = 2x

Area of circle:

πr²

π(2x)²

π(4x²)

4πx²

12.57x²

Answer:

4πx² square units

Step-by-step explanation:

Area of a circle

[ A = πr² ]

The formula uses the radius of the circle, but we have the diameter. Remember the relation :

Diameter = 2 x Radius4x = 2 x RadiusRadius = 4x/2 = 2x

Now, we can solve.

⇒ A = πr²⇒ A = π(2x)²⇒ A = 4πx² square units

Answer:

  95 in²

Step-by-step explanation:

The total area of a pyramid is the sum of the areas of the triangular faces and the area of the base.

__

face area

Here, each triangular face has a base of 5 in, and a slant height of 7 in. Its area will be given by the area formula for a triangle:

  A = 1/2bh

  A = 1/2(5 in)(7 in) = 35/2 in² . . . . area of one of four congruent faces

__

base area

The area of the base is that of a square with 5-inch sides. It is given by the formula ...

  A = s²

  A = (5 in)² = 25 in²

__

total area

Then the total surface area is .

  area of base + 4 × triangle area

  = 25 in² + 4(35/2 in²) = 95 in² . . . . . surface area of the pyramid
