Step-by-step explanation:

To find the total number of text messages sent per month by the 23 million people aged 13-17 in the United States, we can multiply the average number of text messages per person (800) by the number of people (23,000,000):

Total number of text messages = 800 text messages/person/month x 23,000,000 people

Total number of text messages = 18,400,000,000 text messages/month

To express this number in scientific notation, we can move the decimal point 10 places to the left, since there are 10 digits to the right of the decimal point:

Total number of text messages = 1.84 x 10^10 text messages/month

Therefore, the total number of text messages sent per month by the 23 million people aged 13-17 in the United States is approximately 1.84 x 10^10 text messages.

Applying the angle relationships, the measures are: 1. m<A = 18°; m<B = 40°; 2. m<A = 9°; m<B = 43°; 3. m<C = 123°; m<D = 158°; 4. m<C = 131°; m<D = 160°

The position of the angle relationships in the image shown will determine the measures of the angles involved.

Therefore, we have the following for Figure  A:

1. m<D = 162°; m<C = 122°

m<A = 180 - 162 = 18° [the angle relationship is linear pair]

m<B = 180 - 122 - 18 = 40° [triangle sum theorem]

2. m<D = 171°; m<C = 128°

m<A = 180 - 171 = 9° [the angle relationship is linear pair]

m<B = 180 - 128 - 9 = 43° [triangle sum theorem]

3. m<A = 22°; m<B = 35°

m<C = 180 - 22 - 35 = 123° [triangle sum theorem]

m<D = 180 - 22 = 158° [the angle relationship is linear pair]

4. m<A = 20°; m<B = 29°

m<C = 180 - 20 - 29 = 131° [triangle sum theorem]

m<D = 180 - 20 = 160° [the angle relationship is linear pair]

Therefore, we have the following for Figure  B:

9. m<A = 65° [given]

m<B = 180 - 65 = 115° [linear pair]

m<C = 65° [corresponding angles]

m<D = m<B [corresponding angles]

m<D = 115°

m<E = m<C = 65° [vertical angles]

m<F = 180 - 65 - 90 = 25

10. m<A = 70° [given]

m<B = 180 - 70 = 110° [linear pair]

m<C = 70° [corresponding angles]

m<D = m<B [corresponding angles]

m<D = 110°

m<E = m<C = 70° [vertical angles]

m<F = 180 - 70 - 90 = 20

11. m<F = 22° [given]

m<E = 180 - 90 - 22 = 68°

m<E = m<C = 68° [vertical angles]

m<A = m<C = 68° [corresponding angles]

m<B = 180 - 68 = 112° [linear pair]

m<D = m<B = 112° [corresponding angles]

Therefore, the angle of depression from Lisa's line of sight to the cat is approximately 12.21 degrees.

An angle is a geometric figure formed by two rays (or line segments) that share a common endpoint, called the vertex. The rays are also called the sides or legs of the angle. Angles are usually measured in degrees, with a full circle measuring 360 degrees. Angles are used to describe the direction of an object, the orientation of a shape, or the position of a line. They are also used in trigonometry to calculate distances and heights in triangles, and in many other areas of mathematics and science.

Here,

In the diagram above, we have Lisa standing at point L and looking out the window of the building at her lost cat at point C, which is 58.5 meters away from the building. The height of the window from the ground is 12.6 meters. Let's call the angle of depression from Lisa's line of sight to the cat as ∠WLC. To find this angle, we need to use the tangent function, which relates the opposite side (12.6 meters) and adjacent side (58.5 meters) of ∠WLC.

tan ∠WLC = opposite / adjacent

tan ∠WLC = 12.6 / 58.5

Using a calculator, we get:

∠WLC = tan⁻¹(12.6 / 58.5)

∠WLC ≈ 12.21 degrees

If a triangle has one side length of 9cm and another side of .12cm . The 3 possible answers for the third side​ are:  17, 20, and 21.

To determine the possible lengths for the third side of the triangle, we can use the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side.

Using this theorem, the possible lengths for the third side can be found by checking which of the following inequalities hold:

   9 + 12 > x

   9 + x > 12

   12 + x > 9

Simplifying these inequalities, we get:

   x > -3 (always true)

   x > -9 (always true)

   x > -3 (always true)

Therefore, the possible lengths for the third side of the triangle must satisfy x > -9, which eliminates the answer 3 (which is less than 9 - 12 = -3).

The possible lengths for the third side are:

   9 + 12 > x, so x < 21

   9 + x > 12, so x > -3

   12 + x > 9, so x > -3

Therefore, the possible lengths for the third side of the triangle are:

   17 (9 + 12 = 21, which is greater than 17)

   20 (9 + 12 = 21, which is greater than 20)

   21 (9 + 12 = 21, which is equal to 21)

So, the three possible lengths for the third side of the triangle are 17, 20, and 21.

Applying equations, the number of each type of pancake are originally: 81 blueberry pancakes, 27 plain pancakes, and 42 chocolate chip pancakes.

Let's use the following variables to represent the number of each type of pancake:

From the problem statement, we know that:

x + y + z = 150 (total number of pancakes)

1/3 x blueberry pancakes are left

4/5 y plain pancakes are left

1/2 z chocolate chip pancakes are left

There are now an equal number of each type of pancake

From the last statement, we can set up the following equations:

1/3 x = y = 1/2 z

Multiplying all sides of each equation by the least common multiple of the denominators, we get:

2x = 6y = 3z

Dividing all sides of each equation by 2, we get:

x = 3y = 3/2 z

Now we can use the equation x + y + z = 150 to substitute for x in terms of y and z:

3y + y + 2/3(3/2z) = 150

Simplifying and solving for z, we get:

5z = 270

z = 54

Substituting z = 54 into x = 3/2 z, we get:

x = 81

Substituting z = 54 into y = x/3, we get:

y = 27

The total cost for one admission and r rides is $10 for admission and $2 multiplied by r for the rides, which can be expressed as the formula: Cost = $10 + $2r.

The problem statement provides two pieces of information: the admission cost and the ride cost. We are asked to find the total cost for one admission and r rides.

The admission cost is straightforward - it is a fixed cost of $10. This means that regardless of how many rides you go on, you will always pay $10 just to get into the fair.

The ride cost is based on the number of rides you go on. Each ride costs $2, so if you go on r rides, you will pay $2 multiplied by r, or 2r, for the ride portion of the cost.

To find the total cost for one admission and r rides, we simply add the admission cost of $10 to the ride cost of 2r, which gives us the formula:

Cost = $10 + $2r

This formula tells us that the cost of one admission and r rides is equal to $10 plus $2 multiplied by the number of rides (r) that the person goes on.

A quadratic equation is an equation of the form:

ax² + bx + c = 0

where x is the variable, and a, b, and c are constants, with a ≠ 0.

The term "quadratic" comes from the fact that the highest power of x in the equation is 2 (i.e., x is raised to the second power).

Quadratic equations can be solved using a variety of methods, including factoring, completing the square, and using the quadratic formula.

Let's assume the length of the bookmark to be 'l' and the width to be 'w'.

We know that the perimeter of a rectangle is given by:

Perimeter = 2(length + width)

Substituting the values, we get:

18 = 2(l + w) --- (1)

We also know that the area of a rectangle is given by:

Area = length x width

Substituting the values, we get:

18 = l x w --- (2)

We can use equation (2) to solve for one variable in terms of the other:

l = 18/w

Substituting this in equation (1), we get:

18 = 2(18/w + w)

Simplifying, we get:

9 = 9/w + w

Multiplying both sides by 'w', we get:

w² + 9w - 18 = 0

Using the quadratic formula, we get:

w = (-9 + √(117))/2 or w = (-9 - √(117))/2

Since the width of the bookmark can't be negative, we discard the second solution.

Therefore, the width of the bookmark is:

w = (-9 + √(117))/2

We can use equation (2) to find the length of the bookmark:

l = 18/w

Substituting the value of w, we get:

l = 18/(-9 + √(117))

Simplifying, we get:

l = (-18 + 2√(117))/9

Therefore, the dimensions of the bookmark are:

The probability of drawing two yellow marbles without replacement is approximately 0.412 or 41.2%.

What is probability ?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability is used to make predictions, analyze risks, and make decisions in various fields such as science, economics, and finance.

The probability of drawing a yellow marble on the first draw is 9/14, since there are 9 yellow marbles out of a total of 14 marbles in the bag. Since the first marble is not replaced before the second draw, there will be 8 yellow marbles left in the bag out of a total of 13 marbles.

So, the probability of drawing a yellow marble on the second draw, given that the first marble was yellow, is 8/13.

To find the probability of both marbles being yellow, we need to multiply the probability of drawing a yellow marble on the first draw by the probability of drawing a yellow marble on the second draw, given that the first marble was yellow:

P(both yellow) = P(first yellow) x P(second yellow | first yellow)

= 9/14 x 8/13

= 0.412

Therefore, the probability of drawing two yellow marbles without replacement is approximately 0.412 or 41.2%.
