4. Sin N =

Answers

Answer:

[tex]\sin L = 0.60[/tex]

[tex]tan\ N = 1.33[/tex]

[tex]\cos L = 0.80[/tex]

[tex]\sin N = 0.80[/tex]

Step-by-step explanation:

Given

See attachment

From the attachment, we have:

[tex]MN = 6[/tex]

[tex]LN = 10[/tex]

First, we need to calculate length LM,

Using Pythagoras theorem:

[tex]LN^2 = MN^2 + LM^2[/tex]

[tex]10^2 = 6^2 + LM^2[/tex]

[tex]100 = 36 + LM^2[/tex]

Collect Like Terms

[tex]LM^2 = 100 - 36[/tex]

[tex]LM^2 = 64[/tex]

[tex]LM = 8[/tex]

Solving (a): [tex]\sin L[/tex]

[tex]\sin L = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin L = \frac{MN}{LN}[/tex]

Substitute values for MN and LN

[tex]\sin L = \frac{6}{10}[/tex]

[tex]\sin L = 0.60[/tex]

Solving (b): [tex]tan\ N[/tex]

[tex]tan\ N = \frac{Opposite}{Adjacent}[/tex]

[tex]tan\ N = \frac{LM}{MN}[/tex]

Substitute values for LM and MN

[tex]tan\ N = \frac{8}{6}[/tex]

[tex]tan\ N = 1.33[/tex]

Solving (c): [tex]\cos L[/tex]

[tex]\cos L = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos L = \frac{LM}{LN}[/tex]

Substitute values for LN and LM

[tex]\cos L = \frac{8}{10}[/tex]

[tex]\cos L = 0.80[/tex]

Solving (d): [tex]\sin N[/tex]

[tex]\sin N = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin N = \frac{LM}{LN}[/tex]

Substitute values for LM and LN

[tex]\sin N = \frac{8}{10}[/tex]

[tex]\sin N = 0.80[/tex]

Find the area and perimeter of this shape.

PLEASE show step-by-step.

Answers

Answer:

52 ft.

Step-by-step explanation:

there are 8 side that are 3 ft: 3×8=24

there are 4 sides that are 7 ft: 7×4=28

add it and you get: 24+28= 52

The area and perimeter of this shape are 133 ft² and 52 ft respectively.

What is area and perimeter?

Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.

Given that, a figure we need to find its perimeter and the area,

The figure we will be divided into 4 rectangles with sides 7 ft and 3 ft and a square, with side 7 ft

So, the area of the square = side²

= 7² ft²

= 49 ft²

Now, the area of a rectangle = length x width = 4 x 3 x 7 [since there are 4 rectangles]

= 4 x 3 x 7 = 84 ft²

The whole area = 84 + 49 = 133 ft²

Now, the perimeter = sum of the sides = 7 x 4 + 3 x 8 = 28 + 24 = 52 ft

Hence, the area and perimeter of this shape are 133 ft² and 52 ft respectively.

Ling earns $8 per hour working at the zoo. Write and solve an inequality that can be used to find how many hours she must work in a week to earn at least $120. Interpret the solution.

Answers

Answer:

Ling should atleast work 15 hours a week to earn $120.

Step-by-step explanation:

Ling earn per hour = $8

Let the number of hours she worked to be x.

Now, inequality =  

[tex]8x \geq 120[/tex]

Dividing both side by 8.

[tex]\dfrac{8x}{8} \geq \dfrac{120}{8}[/tex]

Answer:

Hanna's typing speed is one word fewer than that of Becky's speed.

What is the general equation of a Straight line? What is equation modelling?

The general equation of a straight line is -

y = mx + c[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

(y - y₁) = m(x - x₁)                                  {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁)        {Two point - slope form}x/a + y/b = 1                                          {intercept form}x cos(β) + y sin(β) = L                          {Normal form}

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are Hannah and Becky, who are learning to type on a computer keyboard. Hanna's typing speed is represented by the equation y = 11z. Becky's typing speed is given by the graph as shown in the question.

Now, for Hanna, her typing speed would be -

11 words per minute

For Becky, the slope of the graph will be -

m = (24 - 12)/(2 - 1)

m = 12

12 words per minute

It can be seen easily that Hanna's typing speed is one word fewer than that of Becky's speed.

Therefore, Hanna's typing speed is one word fewer than that of Becky's speed.

Stacy is covering the box below with sticky wrapping paper. If the paper cost 2 cents per square centimeter, how much will it cost to cover the entire box.

Answers

Given:

The shape of box is a right triangular prism.

Paper cost = 2 cents per square centimeter

To find:

The cost to cover the entire box.

Solution:

In the given right triangular prism, we have 3 rectangle surfaces and 2 triangular surfaces.

Area of a rectangle is

[tex]Area=length\times width[/tex]

Area of rectangle with length 4 cm and width 3 cm is

[tex]A_1=4\times 3=12\text{ cm}^2[/tex]

Area of rectangle with length 4 cm and width 4 cm is

[tex]A_2=4\times 4=16\text{ cm}^2[/tex]

Area of rectangle with length 4 cm and width 5 cm is

[tex]A_3=4\times 5=20\text{ cm}^2[/tex]

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Area of triangle with base 3 cm and height 4 cm is

[tex]A_4=\dfrac{1}{2}\times 3\times 4[/tex]

[tex]A_4=\dfrac{12}{2}[/tex]

[tex]A_4=6\text{ cm}^2[/tex]

Bottom and top triangular surfaces are equal.

[tex]A_5=A_4=6\text{ cm}^2[/tex]

Now, total surface area of the box is

[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]

[tex]A=12+16+20+6+6[/tex]

[tex]A=60\text{ cm}^2[/tex]

Paper cost = 2 cents per square centimeter

Cost of 60 square centimeter paper is

[tex]60\times 2=120\text{ cents}[/tex]

Therefore, the cost to cover the entire box is 120 cents or $1.2.

Step one:

given data

cost of computer=  $2500

rate of loss per year= 18%

time t= 4 years

Step two:

let us computer the loss per year

Year 1 loss

worth= 2500- 2500*0.18

worth= 2500-450

worth= $2050

Year 2 loss

worth= 2050- 2050*0.18

worth= 2050-369

worth= $1681

Year 3 loss

worth= 1681-  1681*0.18

worth= 1681-302.58

worth= $1378.42
