solve x squared minus 2x minus 15 equals 0 using the zero product property

To find the number of student and adult tickets sold at a baseball game, we can set up a system of equations using the given information. Solving the system of equations will give us the values of the variables. In this case, 150 student tickets and 250 adult tickets were sold.

Let's assume that the number of student tickets sold is 'x' and the number of adult tickets sold is 'y'.

According to the information given, the total attendance was 400 people, so we can write the equation: x + y = 400.

The total ticket sales were $1050, so we can write another equation: 2x + 3y = 1050.

Now we have a system of equations that we can solve to find the values of x and y.

Using substitution or elimination method, we find that x = 150 and y = 250.

Therefore, 150 student tickets and 250 adult tickets were sold.

To determine if a pair of numbers is relatively prime, we need to find their greatest common divisor (GCD). If the GCD is 1, then the numbers are relatively prime. The pair 14 and 81 is relatively prime.

For two numbers to be relatively prime, their greatest common divisor (GCD) must be 1.

We can find the GCD by finding the prime factors of each number and determining if they have any common factors.

Let's take a look at each pair of numbers:

Therefore, the pair of numbers that is relatively prime is 14 and 81.

The perimeter of a rectangle is an application of the Distributive property is shown below.

The dividing Property it is necessary to multiply each of the two integers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two words.

This property can be stated symbolically as: A ( B+ C) = AB + AC.

Given:

As, we know the perimeter of a rectangle is twice the sum of its length and width.

let length of rectangle be 'l' unit and width of rectangle is 'w' unit.

So, the Perimeter of rectangle =2L+2W

                                                   =  2(L+W)

Here, 2 is distributed over length of width in parenthesis.

Answer:

Correct answers of Logan is 19.

Step-by-step explanation:

Since, Logan didn't answered one problem.

Thus, total problem he attempt is 24.

Let the number of correct answer = x

and, Number of wrong answer = y

Then x + y = 24

And since it is given that,

He earned 4 points for correct answer and deduct 2 points for wrong answer. and he got score 66.

Thus we get equation,

4x - 2y = 66

Solving these two equation we get,

x = 19 and y = 6

Thus, Correct answers of Logan is 19.

Answer: It’s C

Step-by-step explanation:

Lynn's method of multiplying 4 by 305 and doubling the result will not give her the correct answer to 44 x 305. This method is equivalent to multiplying by 8, not 44.

Lynn's method will not give her the correct answer. When Lynn multiplies 4 by 305 and then doubles the product, she is effectively multiplying 305 by 8, not by 44. To show this, consider the mathematical operations: when we multiply 4 by 305 we get 1220, and when we then double 1220 we get 2440. This is different from the result of multiplying 44 by 305, which is 13420. Therefore, the correct answer is C. Lynn's method will not be correct. Therefore, multiplying by 4 and then doubling the product is the same as multiplying by 8, not 44.

The difference in quotients arises because dividing by smaller numbers results in larger quotients. For example, 80,000 divided by 2,000 equals 40, while dividing by 200 equals 400, and by 20 equals 4,000.

To understand this, let's calculate each quotient step-by-step:

The differences in results are due to the different divisors. As you divide by smaller numbers, the quotient increases because each division breaks the total into more parts.

Division and multiplication are closely related; dividing by a number is the same as multiplying by its reciprocal.

Summary

The fundamental concept here is that dividing by a larger number results in a smaller quotient, whereas dividing by a smaller number results in a larger quotient. This difference is evident when comparing the quotients of 80,000 divided by 2,000 (40), 200 (400), and 20 (4,000).

To estimate the height of a mountain using angles of elevation from two points, set up a system of trigonometric equations based on right triangles and solve for the height using algebra.

To estimate the height of a mountain given two angles of elevation at different points, we use trigonometric concepts. At the first point, the angle of elevation is 32°, and at a point 1000 feet closer, the angle is 35°. To solve this, we can set up two right triangles that share the same height (the mountain) but have different base lengths. Denote the height of the mountain as h, the distance from the first observation point to the base of the mountain as d, and use the trigonometric tangent function:

Tan(32°) = h / d

Tan(35°) = h / (d - 1000)

This creates a system of two equations with two variables. We solve for h by manipulating the equations to isolate h and substituting into one of the equations. We can use trigonometric tables or a calculator to find the values for Tan(32°) and Tan(35°), and then solve for the distance d, which subsequently allows us to find the height h by simple algebraic rearrangement.
