I need help with number 6

Answer:

D)24˚

Step-by-step explanation:

Since you know a full turn is 360˚ since we need to find "b"

we add 41˚ with 295˚

which is 336

then subtract 360 with 336

which is 24˚

So the answer is D) 24˚

Hope this helps!

Answer:

hi there user!

The correct answer should be option D!

Step-by-step explanation:

circle angle: 360 degrees

360 - (295 + 41) =

360 - 336 =

24

Answer:

x=24

Step-by-step explanation:

Because the triangle is a 30-60-90 triangle, you can find side x, the hypotenuse, by doubling the short side 12. Therefore, x=2(12)=24.

Answer:

The vector AB is represented by (11, 2).

Step-by-step explanation:

Given two points on the same plane, we can determine the vector [tex]\overrightarrow{AB}[/tex] by this formula:

[tex]\overrightarrow{AB} = B(x,y) - A(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Coordinates of point A.

[tex]B(x, y)[/tex] - Coordinates of point B.

If we know that [tex]A(x,y) = (3, 7)[/tex] and [tex]B(x,y) = (14,9)[/tex], then the vector AB is:

[tex]\overrightarrow {AB} = (14,9) - (3,7)[/tex]

[tex]\overrightarrow{AB} = (11, 2)[/tex]

The vector AB is represented by (11, 2).

Answer:

It's (1)

Step-by-step explanation:

It's (1) since it's not a constant rate so it's not (3) or (4) and it's increasing so it's not (2).

Answer:

  BC = 6

Step-by-step explanation:

Tangents from the same point are congruent, so ...

  2x = x+3

  x = 3 . . . . . . . subtract x

  BC = x+3 = 3+3 = 6 . . . . . . substitute for x

The length of BC is 6.

Explanation:

The left and right walls are mirror copies of one another, and they are also copies of the cross section as well. Think of a subdivision to divide one room into two smaller ones. That middle wall is the same as the left and right walls of the original larger room. Effectively, those two smaller rooms are blocks of their own we can pull apart or cut.

Answer:

D) 120⁰

Step-by-step explanation:

241 + 47 + (x-48)=360⁰. (sum angles at a point)

241 +47+x-48=360⁰

240+x= 360⁰

x=360⁰-240⁰

x=120⁰

Answer:

An expression to represent the length of the side of the square with an area of 4x^2+12x+9 in terms of x is 2x + 3

Step-by-step explanation:

all sides of a square are equal in length.

area of a square is the side length squared.

area a, side s, variable x.

a = 4x^2 + 12x + 9.   s = ?   x = ?

a = s^2.

a = 4x^2 + 12x + 9.

4x^2 + 12x + 9 = s^2.

x^2 + 3x + 9/4 = (s^2)/4.

factor x^2 + 3x + 9/4 = (s^2)/4.

(x + 3/2)(x + 3/2) = (s^2)/4.

(x + 3/2)^2 = (s^2)/4.

√((x + 3/2)^2) = √((s^2)/4).

take positive root.

x + 3/2 = s/2

solve for side s.

s/2 = x + 3/2

s = 2x + 3

Answer: If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

Step-by-step explanation:

If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

A contrapositive statement is when you take the original statement, "flip" it around, and write the opposite of the original statement. Here's an example:

Original statement: The grass is wet because it was raining.

Contrapositive statement: It was not raining, so the grass is not wet.

Notice how we "flipped" the original sentence around, as wrote it's "opposite".

Answer:

(4, -3)

Step-by-step explanation:

(-4, -3) reflected y-axis => (4, -3)

Answer:

B

Step-by-step explanation:

∠ ABC = 9x + 5 ( alternate angles )

∠ ABC and ∠ DCB are sam- side interior angles and sum to 180° , that is

9x + 5 + 16x = 180

25x + 5 = 180 ( subtract 5 from both sides )

25x = 175 ( divide both sides by 25 )

x = 7

Then

∠ ABC = 9x + 5 = 9(7) + 5 = 63 + 5 = 68° → B

Answer:

there will be about 115 customer

Step-by-step explanation:

the y intercept is 2.5

(0,2.5)  (100 ,35)

the slope is (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = .325

y = mx+b

y = .325x+2.5

let y =40  for 40 cars in all the spot

40 = .325 x + 2.5

subtract 2.5

37.5 =.325 x

divide by .325

37.5 /.325 = x

115.4 = x

there will be about 115 customer

The correct value of Cos K is 5/23

Step-by-step explanation:

In a right angle triangle, there are 3 side

1. Hypothenus (this is the longest)

2. Adjacent

3. Opposite

However, we can only determine the adjacent and opposite if an angle is marked in the triangle.

Now, we shall determine the value of Cos K. This can be obtaineasobtain as followed:

From the question given above, the following data were obtained:

Hypothenus = 23

Adjacent = 5

Cos K =? C

The value of Cos K can be obtained by using the cosine ratio as as illustrated below:

[tex]Cos K =\frac{Adjacent}{Hypothenus}\\\\Cos K = \frac{5}{23}[/tex]

Therefore, the value of Cos K is 5/23

[tex]\text{D. }44.\overline{4}[/tex]

Step-by-step explanation:

*The person who asked this question clarified answer choice D should be [tex]\text{D. }44.\overline{4}[/tex].

Define a terminating decimal by a decimal that has a finite (or fixed) number of digits. Answer choices A, B, and C all have a finite number of digits, thus they are terminating decimals. The overline is answer choice D is using to represent that digit (4) is repeating and therefore there are an infinite number of digits in the decimal. Thus, [tex]\boxed{\text{D. }44.\overline{4}}[/tex] is not a terminating decimal.

Answer:

Angle 1)  S = 12

Angle 2) Y = 18

Angle 3) R = 27

Angle 4) Z = 15

Angle 6) X = 13

Step-by-step explanation:

Angle 1

is a right angle, 90, use this to find s also

90 = (16s - 102)

90 + 102 = 16s

192/16 = s

12 = s

Angle 6

Angle 6 = 180

180 = 12x+24

180 - 24 = 12x

156 / 12 = x

13 = x

Angle 2

Angles 2 and 4 are a total of 90

Use this to find y

90 = (4y-9) + (y+9)

90 + 9 - 9 = 5y

90 = 5y

90/5 = y

18 = y

Angle 4

Angle 4 and 3 will be the same, us this to find z

2z - 3 = 4z - 33

2z - 3 - 4z = -33

-2z  = - 30

z = 15

Angle 3

3 and 5  together from 180

this mean

r + 5r + 18 = 180

6r = 180 - 18

6r = 162

r = 162 / 6

r = 27

Answer:

25 feet per second.

Step-by-step explanation:

Let s represent the speed of the water and r represent the radius of the whirlpool.

The speed in a whirlpool varies inversely with the radius. Therefore, we can write that:

[tex]\displaystyle s=\frac{k}{r}[/tex]

Where k is the constant of variation.

We know that the speed is 2.5 feet per second when the radius is 30 feet.

So, s = 2.5 when r = 30. Substitute:

[tex]\displaystyle 2.5=\frac{k}{30}[/tex]

Solve for k:

[tex]k=30(2.5)=75[/tex]

So, our equation is:

[tex]\displaystyle s=\frac{75}{r}[/tex]

Then when the radius is three feet, r = 3. Evaluate for s:

[tex]\displaystyle s=\frac{75}{(3)}=25\text{ feet per second}[/tex]

So, the speed of the water in a whirlpool with a radius of three feet is 25 feet per second.

Step-by-step explanation:

Part A:

The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].

What we're given:

Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]

Part B:

The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]

Part C:

The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].

What we're given:

Substituting given values, we get:

[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]

Answer:

Answer B is the correct answer..

cot(theta)=cos(theta)/sin(theta)

Trignometric functions are the ratio of the sides of the triangle. The correct option from the following is cot(theta)= cos(theta)/sin(theta).

The trigonometric function gives the ratio of different sides of a right-angle triangle. There are six basic trigonometric functions,

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta= \dfrac{Sin \theta}{Cos \theta} =\dfrac{Perpendicular}{Base} \\\\\\Cosec \theta=\dfrac{1}{Sin\theta}=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta= \dfrac{1}{Cos\theta} = \dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{1}{Tan\theta}= \dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

As we know about the basic trigonometric functions, therefore, the options that is correct from the following option is cot(theta)= cos(theta)/sin(theta).
