The value of the angle x will be 40°. Then the correct option is B.

The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.

The minor arc  is 75°. And the another arc is 130°.

We know that the complete circle subtends 360 degrees.

Then the measure of the major arc will be

Major arc + 130° + 75° = 360°

       Major arc + 205° = 360°

                   Major arc = 155°

Then the value of the angle x will be given by the half of the difference of the major arc to minor arc.

x = (Major arc – minor arc) / 2

x = (155 – 75)/2

x = 80 / 2

x = 40°

Thus, the value of the angle x will be 40°.

Then the correct option is B.

Answer:

2000

Step-by-step explanation:

Salim will need to get 2000 clicks in order to get $50 per month or more.

First: 5 cents goes into one dollar 20 times.

Second: You multiply 20 times 50. This is how you get 2000. There is your answer.

Salim needs at least 700 clicks per month  in order to earn $50 per month or more

A linear equation is in the form:

y = mx + b;

where y, x is variable, m is the rate of change and b is the y intercept.

Let y represent the total pay Salim earns and x represent the number of clicks.

Salim's Website earns $15 per month plus $0.05 every time a visitor clicks, hence:

y = 0.05x + 15

Answer:

the answer is: [tex]\{3, 9\}[/tex]

Step-by-step explanation:

Given a set:

Let S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Two subsets,

One subset of odd numbers:

A = {1, 3, 5, 7, 9, 11, 13, 15, 17, ......}

Other subset of multiples of 3:

B = {3, 6, 9, 12, 15, .....}

To find:

Which number in set S are elements in both A and B.

So, we need to find intersection of A and B provided the number is between 1 to 10 (1 to 10 are the elements of S).

First of all, let us have intersection (i.e. common elements) of A and B:

[tex]A\cap B = \{3, 9, 15, 21, ......\}[/tex]

Now, the numbers between 1 to 10 are:

[tex]\{3, 9\}[/tex]

So, the answer is: [tex]\{3, 9\}[/tex]

She would use 9/7 of a bottle of conditioner for a full year.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

We have been given that Martina used 3/4 of a bottle of conditioner in 7/12 of a year.

Let the amount of conditioner would be x she uses in a full year

As per the given condition, we can write a proportion as

3/4 of a bottle : 7/12 of a year = x : 1

⇒ (3/4) / (7/12) = x / 1

Reciprocal the terms of the denominators,

⇒ (3/4) × (12/7) = x

⇒ 36 / 28 = x

⇒ x = 9/7

Therefore, she would use 9/7 of a bottle of conditioner for a full year.

Answer:

The correct options are;

A. 1·2 = 2

B. 1·1 = 1

E. 1 + 1 = 2

Step-by-step explanation:

Given that the equations 1.2 = 2 and 1.1 = 1 are correctly written as 1·2 = 2 and 1·1 = 2, we have;

The product of any number and one is equal the same number, that is a × 1 = a

Whereby we have the expression 1·2 which is 1 × 2,  we therefore have;

1 × 2 = 1 · 2= 2

B. Similarly we have;

1 · 1 = 1 × 1 = 1

Also, 1 + 1 = 2 is correct as the sum of two numbers is equal to the sum of the count of the numbers, therefore;

E. 1 + 1 = 2 is correct.

Answer: the speed of the elevator is 4.6 miles per hour.

Step-by-step explanation:

Given, The elevator in the Washington Monument takes 75 seconds to travel 506 feet to the top floor.

Since 1 hour = 3600 seconds

⇒ 1 second = [tex]\dfrac{1}{3600}[/tex] hour

⇒ 75 seconds = [tex]\dfrac{75}{3600}[/tex] hour [tex]=\dfrac{1}{48}[/tex] hour

1 mile = 5280 feet

1 feet = [tex]\dfrac{1}{5280}[/tex] mile

506 feet = [tex]\dfrac{506}{5280}[/tex] miles [tex]=\dfrac{23}{240}[/tex] miles

Speed = [tex]\dfrac{Distance}{Time}[/tex]

[tex]=\dfrac{\dfrac{23}{240}}{\dfrac{1}{48}}\\\\=\dfrac{23\times48}{240}\\\\=\dfrac{23}{5}\\\\=4.6\text{ miles per hour}[/tex]

Hence, the speed of the elevator is 4.6 miles per hour.

Answer:  No it does not .

Step-by-step explanation:

First use the coordinates of point A and B to write an equation.

A (-3,-2)

B(2,1)

We will need to use these points to find the slope first and by doing that we will find the difference in the y values and divide it by the difference in the x values.

-2-1= -3

-3-2 = -5

-3/-5= 3/5  

The slope is 3/5 and now we need to find the y intercept using the same points. As you can see the equation will have to be in slope intercept form which uses the formula y=mx+b  where m is the slope and b is the y-intercept.

We will plot the first points in and solve for b.

-2=3/5(-3) + b

-2= -9/5 + b  

+9/5  +9/5

b = -1/5  

We will now write the equation  y=3/5x - 1/5   .

Now using the equation try point c to see if it fits the graph.  

Point C is (5,3)  so again plot in the x and y coordinates and solve,

3= 3/5(5) - 1/5

3 = 3 - 1/5

3[tex]\neq[/tex] 14/5

In this case 3 does not equal 14 over 5 so Point c does not fit the graph

Answer:

(A) 70°

(B) 67°, because they are alternate interior angles

Step-by-step explanation:

For a:

The angles of a triangle will all add up to 180°. Using the "feathers" (lines that signify congruence), we can tell that the angle connecting the two congruent lines will be different than the other two, which will be equivalent to each other.

This means that the angle measure of x will be [tex]180-55-55[/tex], or just [tex]180-110[/tex].

This is equal to 70°.

For b:

We know that the 67° angle and y are formed by the same line intersecting two parallel lines. This means that the angle measures of each intersection point will be the same as the other intersection point, however they will be flipped. This makes the concept of alternate interior angles. We know that the 67° angle and y are formed by the same line, this means that their angle lengths are the same - therefore y is 67°.

Ok so we need to find out the different kinds of variables/constants.

1st kind: -a

2nd kind: -b

3rd kind: 1

4th kind: ab

-a and -b are different because they are different variables, and since their value is not known, you can't add or subtract them together.

-a, -b, and 1 are not the same because -a and -b are variables and their value is unknown. However, 1 is a constant, and it's value is constant and known.

-a, -b, and ab are different because ab are "fused together" (multiplied) and that means you cannot add them separately.

So this expression cannot be factorized.

Answer:

95.44%

Step-by-step explanation:

We can find the percentage of area lies within 2 standard deviations of mean by computing P(-2<Z<2).

So,

P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)

Using normal area table P(0<Z<2)=0.4472. So,

P(-2<Z<2)=0.4472+0.4772

P(-2<Z<2)=0.9544

Thus, the 95.44% of area lies within 2 standard deviations of mean.

Answer:

The height of the pole is 167 m

Step-by-step explanation:

The given parameters are;

Increase  in the length of the shadow = 90 m

Initial angle of elevation of the Sun = 58°

Final angle of elevation of the Sun = 36°

We have a triangle formed by the change in the length of the shadow and the rays from the two angle of elevation to the top of the pole giving an angle 22° opposite to the increase  in the length of the shadow  

We have by sin rule;

90/(sin (22°)  = (Initial ray from the top of the pole to the end of the shadow's length)/(sin(122°)

Let the initial ray from the top of the pole to the end of the shadow's length = l₁

90/(sin (22°)  = l₁/(sin(122°)

l₁ = 90/(sin (22°) ×(sin(122°) = 283.3 m

Therefore;

The height of the pole = 283.3 m × sin(36°) = 166.52 m

The height of the pole= 167 m to three significant figures.

Answer:

height of pole = 121 m (to 3 significant figures

Step-by-step explanation:

From the diagram attached to this solution:

Let the length of the shadow = b

Let the height of the triangle = h

[tex]Triangle\ 1\\\\Tan\ (58)\ =\ \frac{h}{b}\\1.60\ =\ \frac{h}{b} - - - - - -(1)\\\\[/tex]

[tex]Tan\ (36) = \frac{h}{b+90} \\0.73\ =\ \frac{h}{b+90} - - - - (2)[/tex]

[tex]From\ equation\ (1)\\1.60 = \frac{h}{b}\\ cross-multiplying\\1.60b = h - - - - - (3)\\\\\\from\ equation\ (2)\\0.73\ =\ \frac{h}{b+90}\\ corss-multiplying\\0.73b\ +\ 65.7 = h\\h\ =\ 0.73b\ +\ 65.7- - - - - -(4)\\[/tex]

Notice that equation (3) = equation (4) = h

[tex]1.60b = 0.73b\ + 65.7\\1.60b\ -\ 0.73b\ = 65.7\\0.87b\ =\ 65.7\\b\ =\ \frac{65.7}{0.87} = 75.52\ m\\[/tex]

Now let us find the height of pole from equation (3)

1.60b = h - - - - - - (3)

where b = 75.52

h = 1.60 × 75.52

h = 120.83 m

= 121 m (to three significant figure

Answer:

Crew: 32

Marty: 48

Blakely: 24

Step-by-step explanation:

I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.

32 × 1. 5 = 48

Marty is 48. Now, let's find Blakely's age.

32 × 0.75 = 24

Add all the ages together.

32 + 48 + 24 = 104

Hope that helps.

Crew's age is 32, Marty's age is 48 and Blakey's age is 24

Let :

c represent Crew's age

m represent Marty's age

b represent Blakely's age

From the question, the following can be derived

m = 1.5c

b = 0.75c

m + b + c = 104

Substitute for m and b in the above equation

c + 1.5c + 0.75c = 104

3.25c = 104

divide both sides of the above equation by 3.25

c = 104 / 3.25

c = 32

Substitute for c in the equations that represent  Marty and Blakely's age

m = 1.5c

m = 1.5(32)

m = 48

b = 0.75c

0.75(32)
