Answer:369.15

Step-by-step explanation:

Answer:

22 feets

Step-by-step explanation:

From the diagram attached :

We have two similar triangles which can be related proportionally :

Hence ;

Mitchell's height / distance from mirror = cliff height / cliff distance

Michelle's height = 5.5

Michell's distance from mirror = 4

Cliff height = h

Cliff distance from mirror = 16

We have ;

5.5 / 4 = h / 16

Cross multiply :

4 * h = 5.5 * 16

h = 88 / 4

h = 22 feets

Answer:

[tex](a)\ \tan A = \frac{5}{12}[/tex]

[tex](b)\ \cos B = \frac{5}{13}[/tex]

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

[tex]\tan(A)[/tex]

The tan of an angle is:

[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

From the given triangle.

[tex]Opposite = 5[/tex]

[tex]Adjacent = 12[/tex]

So, we have:

[tex]\tan A = \frac{5}{12}[/tex]

Solving (b)

[tex]\cos(B)[/tex]

The cos of an angle is:

[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

From the given triangle.

[tex]Adjacent = 5[/tex]

[tex]Hypotenuse = 13[/tex]

So, we have:

[tex]\cos B = \frac{5}{13}[/tex]

Answer:

33.7 ft

Step-by-step explanation:

We solve the above question using Trigonometric function of Tangent

tan θ = opposite/adjacent

θ = 56°

Opposite = 50 ft

Adjacent = x

Cross Multiply

tan 56 = 50 ft/x

Cross Mulitiply

tan 56 × x = 50ft

x = 50ft/tan 56

x = 33.725425842 ft

Approximately = 33.7 ft

2 - 5.

3 - 3rd option (56)

4 - 3rd option (113)

5 - 10 Im really not sure sorry ):

Step-by-step explanation:

Answer:

No, it does not.

Step-by-step explanation:

A linear function of x will form a straight (non-vertical) line on a graph.

This is caused directly by the equation

y = ax + b

For some constant a and b, which means that the rate of change is constant.

Answer:

0, 1, 1.5, 1.8, 1.3

Step-by-step explanation:

Answer:

x > 17.5

Step-by-step explanation:

So we are given that; [tex]\frac{4x}{7} > 10[/tex]

=> First multiply 7 on each side of "="

4x = 70

=> Now divide 4 on each side

=> x > 17.5

Hope this helps!

Answer:

letter C HOPE it helps.............

Answer:

B. 15 + x < 24

Step-by-step explanation:

12 + 7 = 19 which is > 16 not < so no

15 + 7 = 22 which is < 24 so yes

16 + 7 = 23 which is = 23 not < so no

17 + 7 = 24 which is < 26 not > so no

24 + 7 = 31 which is = 31 not > so no

Answer:

Y-intercept is 7

Step-by-step explanation:

Y-intercept is when the graph crosses the y-axis

Answer:

22=2x+6

Step-by-step explanation:

you subtract 6 from both sides

that leaves u with 16=2x

then divide 2 by 16 and that equals

8

so 8=x

each game costs $8

you put the 2 in front of the x in the beginning due to Toni playing 2 games while the shoes are a one time fee.

Answer:

48in²

Step-by-step explanation:

to find the area of a triangle you first divide the base by 2 then multiply it by the height

Answer:

22969.39 yd^2

Step-by-step explanation:

Alright to start, lets do the easier part of it, the sides of it. Since it is an octagonal prism, there are 8 rectangular sides to it. Each of these sides can be found with L*W, so use the given length of 15 and width of 6 to do this.

15 * 6 = 90

Since there's 8 of these:

90 * 8 = 720

Now, with the tricky part with the bases of the octagonal prism. Let's find the perimeter of the octagon, so use the top width of each of the rectangles.

6 * 8 = 48 = Perimeter

Now, here's the magic equation to avoid making this more complicated:

2(1+√2)p^2

Then plug in p

2(1+√2)48^2

(2+2√2) * 2304

(2+2.8284)*2304

4.8284*2304

11124.69...

But there's two bases so: 22249.39

Lastly, add this to the 720 from the rectangular prisms.

22249.39+720 = 22969.39

Hope that helps.

Answer:

Step-by-step explanation:

Let angle ABZ be angle 1 and angle ZBC be angle 2.

Angle 1 = 85 degree

Angle 2 = 6x + 9

measure of angle ABC = 24x+4

Angle 2 = ABC - 85

6x + 9 = 24x + 4 - 85

6x - 24x = 4 - 85 - 9

-18x = -90

x = -90/-18 = 90/18 =

x = 5

Therefore the measure of angle 2 = 6*5 + 9 = 30+9 = 39 degree

Therefore the measure of angle ZBC = 39 degree
