Step-by-step explanation:

So to count the number of faces, you look for how many flat sides the the figure  has. Looking at the shape, you see that it has a face on top, on the bottom, to the left and to the right, on the front and at the back.

The given figure has five faces, option D is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The given figure is a triangular prism

A triangular prism is a three-dimensional geometric shape that has two congruent triangular bases and three rectangular faces connecting them. Since each triangular base has one face, there are two faces that are triangular.

Additionally, there are three rectangular faces that connect the triangular bases.

Therefore, a triangular prism has five faces in total.

Answer:

2.75feet

Step-by-step explanation:

Given data

Volume= 11.39 cubic feet

Length= 2.3 feet

Width= 1.8 feet

Depth= ???

The expression for the volume is  

Volume= Length*Width*depth

11.39=2.3*1.8*d

11.39=4.14d

d= 11.39/4.14

d= 2.75

Hence the depth is 2.75feet

Answer:

Break-even point in units= 40

Step-by-step explanation:

Giving the following information:

Unitary variable cost= $20

Selling price per unit= $30

Fxed costs= $400

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 400 / (30 - 20)

Break-even point in units= 40

Answer: 3.9 ft

Step-by-step explanation:

From the question, the distance across the window which is 2.5 ft is the diameter. Therefore, radius will be:

= 2.5 / 2

= 1.25 ft

Then, we calculate the circumference of the circle which will be:

= 2πr

= 2 × 3.14 × 1.25

= 7.85 ft

Nite that it's a semi circle, therefore we divide the perimeter by 2. This will be:

= 7.85/2

= 3.9 feet

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

[tex]A = b\cdot h[/tex] (1)

Where:

[tex]A[/tex] - Area.

[tex]b[/tex] - Base.

[tex]h[/tex] - Height.

The base and height of the parallelogram are, respectively:

Base

[tex]b = 8-2[/tex]

[tex]b = 6[/tex]

Height

[tex]h = 5-1[/tex]

[tex]h = 4[/tex]

Then, the area of the parallelogram is:

[tex]A = (6)\cdot (4)[/tex]

[tex]A = 24[/tex]

The area of the paralellogram is 24 square units.

Answer:

1/3

Step-by-step explanation:

Answer:

The probability of is rolling a 1 or a 6 on a die is [tex]\frac{1}{3}[/tex].

Step-by-step explanation:

Since there are six sides to a die, and there are two sides that are either 1 or 6, that means the probability of rolling a 1 or 6 is [tex]\frac{2}{6}[/tex] or [tex]\frac{1}{3}[/tex].

The explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-5}{-1}[/tex] = 5 , then

[tex]a_{n}[/tex] = - [tex]5^{n-1}[/tex]

13

Using the explicit formula for a geometric sequence

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 48 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{96}{-48}[/tex] = - 2 , then

a₁₀ = - 48 × [tex](-2)^{9}[/tex] = - 48 × - 512 = 24576

Answer: 8:10, 7:54, 26 minutes

Step-by-step explanation:

a) Go to the row labeled Church Street, start in the column with time 7:59, read down until you get to the row labeled Bus Station.

b) Go to the High Street row. The latest arrival time that is still before 8:30 is 8:10. Starting in the column with 8:10, read UP to the Hope Street row. The bus leaves there at 7:54

c) Pick any column in the row for School Road. In that column, read down to the Bus Station row. The difference between the two times is 26 minutes no matter which column is selected.

Answer:

7.5

Step-by-step explanation:

Using similar triangles.

Answer:

ED=7.5

Step-by-step explanation:

ΔABC is similar to ΔDEB (they share ∠B, and ∠C=∠D and ∠A=∠E because corresponding angles), so their sides are in ratio:

ED/AC=BD/BC

We can see that BC is twice BD (marked), so we know BD/BC=0.5

ED/AC=BD/BC

ED/15=0.5

ED=7.5

Answer:

B) (3,1)

Step-by-step explanation:

y = -2x + 7

y = 3x - 8

3x - 8 = -2x + 7

combine like terms:

5x = 15

divide both sides of the equation by 5:

x = 3

y = 3(3) - 8 = 1
