A net of a triangular prism is shown below. 42 8 ft 3 ft 5 f 5 ft What is the surface area, in square feet, of the triangular prism? A 44 B 96 C 108 D 120

Answer:

Step-by-step explanation:

it is an ellipse.

The graph of the ellipse (x²/3²) + (y²/2²) = 1 is given in the image below.

An ellipse is a closed curve in a plane that is symmetric around two perpendicular lines known as the ellipse's axis.

The given equation is in the standard form of the equation of an ellipse centered at the origin with its major axis on the x-axis and its minor axis on the y-axis:

(x²/3²) + (y²/2²) = 1

The square of the semi-major axis (a) is 3² = 9, so the semi-major axis is a = 3.

The square of the semi-minor axis (b) is 2² = 4, so the semi-minor axis is b = 2.

Therefore, the characteristic of the given ellipse is:

a²- b² = 9 - 4 = 5

So the characteristic of the ellipse is 5.

Answer:

Perimeter of the given patio is [tex](\pi+6)y + 10x +8[/tex].

Step-by-step explanation:

Let us first label the given patio using the points A, B, C, D, E and F as shown the attachment diagram.

Perimeter of given figure can be found by the following:  

Perimeter of polygon ABPCDEQF + Perimeter of semi-circle with diameter as EF.  

Let us mark points P and Q on sides AB and FA respectively.  

These points P and Q are just opposite to point D. Please refer to attached diagram for details.

As this figure has symmetry so, sides  

[tex]side\ AP =side\ FE\ i.e\ 2y\\side\ AQ =side\ BC\ i.e.\ 2y\\side\ PB =side\ CD\ i.e.\ 3x+5\\side\ QF =side\ DE\ i.e.\ 2x-1[/tex]

Perimeter of polygon APBCDEQF = AP + PB + BC + CD + DE + FQ + QA (Side EF is not on the periphery so it is excluded)

[tex]\Rightarrow 2y + (3x+5) + 2y + (3x+5) + (2x - 1) + (2x-1) + 2y\\\Rightarrow 6y + 10x + 8 ...... (1)[/tex]

Perimeter of semicircle = [tex]\pi \times radius[/tex]

Radius of semicircle is y.  

[tex]\text{Perimeter of semicircle = }\pi \times y ...... (2)[/tex]

Adding equations (1) and (2):  

[tex]\text{Total perimeter = }6y + 10x + 8 + \pi y \\\Rightarrow (\pi+6)y + 10x + 8[/tex]

Perimeter of the given figure is [tex](\pi+6)y + 10x +8[/tex]

Answer:

9 and -4

Step-by-step explanation:

Answer:

Option D

-4, 0

Step-by-step explanation:

We will first of all identify the coordinates we are dealing with here.

The coordinates for this question (x,y)  are: (0,0) and (-8,0)

The next thing we will do is get the formula for finding mid points of line segments.

This is [tex](\frac{x_{1}+x_{2}}{2}, )(\frac{y_{1}+y_{2}}{2}, )[/tex]

Next we will substitute the values of x 1 ,x 2, y 1, and y 2 into the equation.

We will have

[tex](\frac{0+(-8)}{2}, )(\frac{0+0}{2}, )=(-4, 0)[/tex]

Hence the coordinates of the midpoint is (-4,0)

The volume of a given cylinder is 113.04 cubic units.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a cylinder with base radius 2 units and height units.

We know that, the volume of a cylinder is πr²h.

Now, volume = 3.14×2²×9

= 113.04 cubic units

Therefore, the volume of a given cylinder is 113.04 cubic units.

Answer:

0.80A + 0.92B = 63 .....1

A + B = 75 ......2

Step-by-step explanation:

Let A and B represent the total possible score in part A and B respectively;

Analysing each sentence of the question;

Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63

80% of A + 92% of B = 63

0.80A + 0.92B = 63 ......1

The total possible marks for the test was 75;

A + B = 75 .....2

So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.

Solving the simultaneous equations, we will arrive at;

Part A = 50

Part B = 25

Answer: 5.22kg

Step-by-step explanation:

From the question, a farmer sells 8.7 kilograms of pears and apples at the market. Of the pears and apples sold, 2/5 of this weight is pears, and the rest is apples. To calculate the kilograms of apple sold goes thus:

Total kilograms sold = 8.7kg

Fraction of pears weight = 2/5

Pears kilograms sold = 2/5 × 8.7

= 0.4 × 8.7

= 3.48kg

Since the kilograms of pears sold is , 3.48kg, to get the kilograms of apple sold, we subtract 3.48kg from 8.7kg. This will be:

= 8.7kg - 3.48kg

= 5.22kg

Expressions can be represented as equations or inequalities or neither.

The required expression is: 7 * 52 - 6

7 times the quantity of 52 means 7 * 52

More than 6 means we subtract 6 from 7 * 52

So, we have:

7 * 52 - 6

Hence, the expression that shows 7 times the quantity of 52 more than 6 is: 7 * 52 - 6

Answer:

[tex]V=8,448u^3[/tex]

Step-by-step explanation:

The volume of a prism is given by:

[tex]V=A_{b}*h[/tex]

where [tex]A_{b}[/tex] is the area of the base, and [tex]h[/tex]  is the height of thr prism.

We know that the height is:

[tex]h=22[/tex]u

and the bases of this prism are hexagons.

Thus the area of the base is the area of a regular hexagon:

[tex]A_{b}=\frac{n*l*a}{2}[/tex]

where [tex]n[/tex] is the number of sides: for an hexagon: [tex]n=6[/tex]

[tex]l[/tex] is the length of each side: [tex]l=8[/tex]u,

and [tex]a[/tex] is the apothem: [tex]a=16u[/tex]

we substitute all of this to find the area of the base:

[tex]A_{b}=\frac{6*8u*16u}{2}\\ \\A_{b}=\frac{768u^2}{2}\\ \\A_{b}=384u^2[/tex]

and finally we use the formula for the volume:

[tex]V=A_{b}*h[/tex]

we get the following:

[tex]V=384u^2*22u\\V=8,448u^3[/tex]

which is the third option

Hello!

[tex]\boxed{ \bf The~marked~up~price~is~$30.}[/tex]The price will be $30.

To find the selling price, we must calculate 20% of $25 and add it to the price.

20% = 0.20

25 × 0.20 = 5

Add this number to the price of the item.

25 + 5 = 30

Answer:

$30

Step-by-step explanation:

$25 item

Markup = Increase

The $25 is increased by 20%

Write 20% as a decimal

Decimal = % / 100

20/100 = 0.2

Multiply 0.2 by 25

0.2(25) = 5

We know that the price that it was marked up is $5

Add this to the original amount ($25) to find the final price after being marked up.

$25 + $5 = $30

x = 12°

Compute, knowing that x = 12°

8x + 4 = 8 · 12 + 4 = 100°
