There are 40 dominos in the set which contains all number pairs from double-0 to double-8.

The domino set contains all number pairs from double-0 to double-8, which means that there are nine possible values for each half of the domino and they are - 0, 1, 2, 3, 4, 5, 6, 7, and 8.

Since each number pair occurs only once, we can count the total number of dominos in the set by counting the number of distinct pairs of values that can be formed by combining the numbers on the two halves of the domino.

There are 9 possible values for the first half of the domino and 9 possible values for the second half, so there are 9 x 9 = 81 possible pairs of values.

However, we need to divide this by 2 to avoid counting each pair twice, since a domino with the values A-B is the same as a domino with the values B-A.

Therefore, the total number of distinct dominos in the set is 81/2 = 40.5, but since dominos cannot be counted in halves, the closest integer number of dominos is 40.

So there are 40 dominos in the set.

The function y=-2x-3 is a linear equation. This means that the graph of the equation is a line with a constant slope. The slope of this line is -2 and the y-intercept is -3. The table above shows the output of the function for different values of x. To calculate the value of y for a given x, the first step is to calculate -2x. Then subtract 3 from the result to get the value of y. For example, for x=-2, -2*(-2)=-4 and -4-3=-3, so y=-3. For x=1, -2*(1)=-2 and -2-3=-5, so y=-5. In this way, the output of the function can be calculated for any given value of x.

One term in the original equation that needs to be changed to create a new equation with infinitely many solutions is 20 to 21.

An equation is a mathematical or algebraic statement that shows that two or more mathematical expressions are equal or equivalent.

Equations are depicted using the equal symbol (=), unlike mathematical expressions, which consist of variables, constants, numbers, and values.

7(2W + 3) = 14W + 20 does not have a solution because the first expression is unequal to the second expression and cannot be said to be an equation.

The equivalent expressions are 7(2)^3x = 7(8)^x, 7(1/2)^x = 7(2)^-x, 7(4)^(3x + 1) = 7(2)^(6x + 2), 14(2)^x = 7(2)^(x + 1) and 14(2)^x = 14(4)^(x/2)

From the question, we have the following parameters that can be used in our computation:

The expressions on the left and those on the right

To do this, we solve the expressions on the left and look for a match

Using the above as a guide, we have the following:

(a) 7(2)^3x

Evaluate the exponent

7(2)^3x = 7(8)^x

(b) 7(1/2)^x

Apply the law of indices

7(1/2)^x = 7(2^-1)^x

So, we have

7(1/2)^x = 7(2)^-x

(c) 7(4)^(3x + 1)

Apply the law of indices

7(4)^(3x + 1) = 7(2^2)^(3x + 1)

So, we have

7(4)^(3x + 1) = 7(2)^(6x + 2)

(d) 14(2)^x and (e) 14(2)^x

Without solving them, we have

14(2)^x = 7(2)^(x + 1)

14(2)^x = 14(4)^(x/2)

The measure of each angle is [tex]3(75)-100=125^{\circ}[/tex].

Variable y in equilateral 60°, Thus correct option is C) 60°.

An equilateral triangle is one with equal-sized sides on all three sides and angles that can all reach a maximum of 60 degrees. An equilateral triangle is a triangle with three equal sides, also referred to as a "regular" triangle. Since all three sides of an isosceles triangle are equal, an equilateral triangle is a special case of an isosceles triangle. Three equal angles of 60 degrees also make up an equilateral triangle.

The sum of all the angles in a triangle is 180.

It is given that the triangle ABC is an equilateral triangle.

So ∠A+∠B+∠C =180°

∠A=B=∠C

3∠A=180°

∠A=60°

Therefore y in ΔABC is C) 60°

The height of the mountain using the angle of elevation is 3858.85 units.

The three basic categories of trigonometric functions are sine, cosine, and tangent. And from the basic functions, one can deduce the three cotangent, secant, and cosecant functions. In contrast to the fundamental trigonometric functions, the other three functions are essentially employed more frequently.

Let the distance between the mountain and Matt = x.

Then the distance of Susie will be:

S = x - 1200

Matt measure the angle of elevation as 35 degrees.

Using the trigonometric function we have:

tan (35) = h / x

x = h/ 0.7.......(1)

For Susie:

tan(42) = h / x - 1200

0.9(x - 1200) = h

0.9x - 1080.48 = h .........(2)

Substitute the value of x in equation 2:

0.9 ( h/ 0.7) - 1080.48 = h

1.28h - 1080.48 = h

1.28h - h = 1080.48

0.28h = 1080.48

h = 3858.85

Hence, the height of the mountain using the angle of elevation is 3858.85 units.

Line a has an equation of y=-x-2, which is the slope-intercept form of the equation of a line. This line has a slope of -1 and a y-intercept of -2. Line b is defined by two points (-6,1) and (3,-14), which can be used to find the equation of the line using the point-slope form of a line.

This line has a negative slope and passes through the points (-6,1) and (3,-14). Line c has two points (-1,8) and (4,11), which can also be used to find its equation using the point-slope form.

You want to find the number of puzzles solved by each boy if they solved 35 puzzles together, and 1/3 of the number Andy solved is twice the number Dale solved.

Let 'a' and 'd' represent the numbers of puzzles solved by Andy and Dale, respectively. Then ...

  a + d = 35

  1/3a = 2d

Multiplying the second equation by 3, we get an expression for 'a' that can be used in the first equation:

  6d +d = 35

  d = 35/7 = 5

  a = 6(5) = 30

The lower quartile for the given data is -2, since it is the 25th percentile and is the value that lies at the 25th position when the data is sorted in ascending order.

1. Sort the data in ascending order: -4, -2, 1, 1, 6, 8, 12, 15

2. Calculate the 25th percentile: 25th percentile = (n + 1) * 0.25 = (8 + 1) * 0.25 = 2.25

3. The 25th percentile is between the 2nd and 3rd values, which are -2 and 1 respectively.

4. The lower quartile is -2.

The lower quartile (also known as the 25th percentile) is the value that lies at the 25th position when the data is sorted in ascending order. To find the lower quartile of the given set of data (1, 8, 1, -4, 12, -2, 15, 6), the data needs to be sorted in ascending order. This gives us the following data: -4, -2, 1, 1, 6, 8, 12, 15. Now, to calculate the 25th percentile, we use the formula (n + 1) * 0.25, where n is the number of data points. In this case, n = 8, so the 25th percentile = (8 + 1) * 0.25 = 2.25. This means the 25th percentile is between the 2nd and 3rd values, which are -2 and 1 respectively. Therefore, the lower quartile for the given data is -2.

To find the x-intercepts of a rational function of the form f(x) = p(x)/q(x), we set p(x) = 0 and solve for x. To find the vertical asymptotes, we set q(x) = 0 and solve for x.

Vertical asymptotes are vertical lines that a function approaches but never touches or crosses as the independent variable (usually denoted as x) approaches a certain value.

To find the x-intercepts of the function, we need to set the numerator of the rational function equal to zero and solve for x. This is because x-intercepts occur when the function value is equal to zero. Therefore, we can write:

p(x) = 0

Solving this equation will give us the values of x where the function intersects the x-axis. It is important to note that if p(x) has a degree greater than or equal to q(x), then the function will have a slant asymptote instead of a vertical asymptote.

To find the vertical asymptotes of the function, we need to look at the denominator of the rational function. Vertical asymptotes occur when the function approaches infinity or negative infinity as x approaches a certain value. In the case of a rational function, this happens when the denominator is equal to zero. Therefore, we can write:

q(x) = 0

Solving this equation will give us the values of x where the function has a vertical asymptote. It is important to note that if the degree of q(x) is greater than the degree of p(x), then the function will have a horizontal asymptote instead of a vertical asymptote.

Here,
The shortest possible distance between the building and the end of the ramp, if the doorway is 1.3 feet above the parking lot, is 1.3 feet.

This is because, if the doorway is 1.3 feet above the parking lot, the ramp will need to rise 1.3 feet in order for a person or vehicle to be able to enter the building.
