Step-by-step explanation:

Answer:

B). 1/6

Step-by-step explanation:

There's 2 sides with length 1/4 and one side with length x.

2 * 1/4 + x = 2/3

2/4 + x = 2/3

6/12 + x = 8/12

x = 2/12

x = 1/6

B is the correct answer because 1/6 is the simplest form of the fraction, while 2/12 is not.

Answer:

0.90 seconds

Step-by-step explanation:

We will see that one complete revolution takes (2π/7) seconds.

Here we have the function:

f(x) = 33sin(7x−π/12) + 33

The time needed to do a full revolution is given by the period of the function.

Remember that:

sin(x) = sin(x + 2π).

Then:

sin(7x−π/12) = sin(7*(x + T) −π/12)

Then we must have:

2π = 7*T

Where T is the period.

Solving for T, we have:

2π/7 = T

This means that one complete revolution takes (2π/7) seconds.

Answer:

The third triangle

Step-by-step explanation:

The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.

So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.

The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.

The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.

The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.

Step-by-step explanation:

Answer:

1) Obtuse angle

2) Obtuse angle

3) Acute angle

You can do 4 and 5. I will give you a hint that acute angles are less than 90 degrees and obtuse angles are more than 90 degrees. And if it is a straight line it is 180 degrees.

6) Angle KLM, MLK, Obtuse angle, and angle 5.

7) Angle DCB, BCD, Obtuse angle, and angle 5.

You can do 8. I will give you a hint that the letters will start from end-middle-end and it can be opposite. If getting confused then look what I did. On muber 6, my I typed angle KLM and angle MLK. Both of them are same but look on how I typed. Also while naming angles, they will be in capital.

Answer:

Step-by-step explanation:

Answer:

Let's denote students in D = in the drama club , S = in a sports team

P(D) = 85/330

P(S) = 200/330

P(D and S) = 60/300

P(D or S) = P(D) + P(S) - P(D and S)  = 85/330 + 200/330 - 60/330 = 15/22

P(neither D nor S) = 1- 15/22 = 7/22

Answer:

4cm

Step-by-step explanation:

Given data

L=(2x+3)

W=(x-1)

P=28cm

A= L*W

A= (2x+3)*(x-1)

open bracket

A= 2x^2-2x+3x-3

collect like terms

A= 2x^2+x-3

P= 2L+2W

P= 2*(2x+3)+2(x-1)

P= 4x+6+2x-2

collect like terms

P= 6x-4

but p= 28

28= 6x-4

28-4= 6x

24= 6x

x= 24/6

x= 4cm

Hence x= 4cm

Step-by-step explanation:

In this scenario, the dependant variable would be the total cost of the rental for the bike. This is because the actual cost depends on the number of hours that the individual has decided to rent the bike. The independant variable is the number of hours that they chose to rent the bike since it does not depend on any other factor in the scenario.

Answer:

The conclusion supported by the diagram is;

(A)  [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

Step-by-step explanation:

The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals

The given parallel lines are;

Line CD, line BE, and line line AB

The given transversals are;

Line AC and line DF

Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;

BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE

From BC/AB = ED/FE, we find the inverse of both sides to get;

[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }[/tex]

[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}[/tex]

[tex]\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

The correct option is [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

Answer: X=4 Y=-6

Step-by-step explanation:

Well we know that y= -4x+10

So we can input that into the bottom equation

2x +2(-4x+10) = -4

2x +-8x+20=-4

-6x + 20= -4

-6x = -24

x = 4

We also have to find the value of Y

y=-4(4)+10

y= -16 + 10

y=-6

Answer:

Step-by-step explanation:

2x + 2y = -4

Substitute (-4x+10) for y:

2x + 2(-4x+10) = -4

2x -8x + 20 = -4

-6x = -24

x = 4

Answer:

Price of bracelet =  $(25 + 5c)

Step-by-step explanation:

As given,

A bracelet = 1 chain + Number of charm selected by customer

Also given,

Price of chain = $25

Price of each charm = $c

As,

we have to write equation for a bracelet with 5 charm

So,

Price of bracelet = Price of 1 chain + Price of 5 charm

As

Price of 1 charm = $c

⇒Price of 5 charm = $5×c = $5c

∴ we get

Price of bracelet = $25 + $5c = $(25 + 5c)

Answer:

multiplication

Step-by-step explanation:

7 x e = f

Answer:

If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.

Step-by-step explanation:

We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.

Let me just give a number to e. Let's say e is 5

7e = f

We already know 7e is the same thing as 7 x e, so let's rewrite it

7 x e = f

We will change e to 5 and multiply the numbers together

7 x 5 = f

Now multiply 7 x 5

35 = f

If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)

But let's now take the original equation and assume f is 42

7e = f

Remember, 7e is 7 x e, so rewrite your equation

7 x e = f

Now we will change the f to 42

7 x e = 42

To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7

42÷7 = 6

That means e is 6. Now let's write the equation with changing e to 6

7 x 6 = 42

7 times 6 is 42, so we will multiply that

42 = 42

Now we have equal answers. Of course, 42 is equal to 42

Overall I'm trying to say 7e = f

I'll solve this again, so you won't have to go back up.

7e = f

7 x e = f

f = f

I hope this makes sense lol

Answer: 65100 Calories

Step-by-step explanation:

Let's believe that there are 31 days in a month. Therefore, the number of days in 6 months will be:
