Step-by-step explanation:

2.5:10 = 1/4

1.4:1.8 = 7/10

0.04: 0.3 = 2/50

1/5: 4/5 = 1/5

3/4: 1/2 = 3/2

6.2:5 2/5 = 12/5

Answer:

x = -16 and x = 1

Step-by-step explanation:

"Finding the roots" means solving the equation. We'll set the equation equal to 0 (replace f(x) with zero) and factor.

0 = x^2 + 15x - 16

0 = (x + 16)(x - 1)

This is factored.

Using the Zero Product Property, we separate this into two small equations.

x+16 = 0 and x-1 = 0

Solve these one-step equations.

x = -16 and x = 1

These are the roots (and roots are solutions, are zeros, are x-intercepts) If the question ask for zeros, roots, solutions or x-intercepts, set it equal to 0, factor and solve.

Answer: Let's call the measure of the angle x.

The complement of the angle is (90 - x) degrees, and the supplement is (180 - x) degrees.

So, using the information given in the problem, we can set up an equation:

5 * (90 - x) = 2 * (180 - x) - 24

Expanding both sides and simplifying, we get:

450 - 5x = 360 - 2x - 24

Solving for x, we get:

6x = 294

x = 49

Therefore, the measure of the angle is 49 degrees.

Using equations, we know that the age of Geraldine and Steven is t - 4 and 2t - 8 respectively.

It basically consists of a variable, perhaps with an additional numerical constant.

To easily understand this concept, consider the example below. 3x – 4 = 5. It is a straightforward class 7 equation.

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.

So, we have the following algebraic expression after converting the word problem:

To Geraldine:

g = t - 4

To Steven:
s = 2g

Inputting Tom's age into equation 1 results in:

g = t - 4

To determine Steven's age:

s = 2(t-4)

s = 2t - 8

Therefore, using equations, we know that the age of Geraldine and Steven is t - 4 and 2t - 8 respectively.

Answer:

160 tourists like only one place. This can be determined by using a Venn diagram. Of the 500 tourists surveyed, 350 like Pokhara, 200 like Chitwan, and 50 like both places. That leaves 20 who like neither of the two places. To get the number of tourists that like only one place, subtract the number of tourists who like both (50) and the number of tourists who like neither (20) from the total number of tourists surveyed (500), resulting in a total of 160 tourists who like only one place.

Work Shown:

A = the 1st marble is blue

B = the 2nd marble is green

Replacement is applied. This makes A and B independent.

P(A) = (4 blue)/(10 total) = 4/10 = 2/5

P(B) = (2 green)/(10 total) = 2/10 = 1/5

P(A and B) = P(A)*P(B) ... see note below

P(A and B) = (2/5)*(1/5)

P(A and B) = 2/25

Note: The equation is valid because events A and B are independent.

To verify if the representation is a function for this problem, we should verify if each input is mapped to a single output. If there is an input that is mapped to more than one output, then the relation is not a function.

A relation represents a function when each input value is mapped to a single output value.

On a graph, a function is represented if the graph contains no vertical aligned points, that is, if there are no values of x at which we could trace a vertical line that would cross the graph of the function more than once.

With arrows, only one arrow can depart from each value of x, or more than one arrow departing from the same value of x but necessarily arriving at the same value of y.

The problem is incomplete, hence the general procedure to verify if a relation represents a function was presented.

The solution of the system of equations is:

x = 3

y = 2

Here we want to solve the system of equations below:

2x + y = 8

x - 3y = -3

First, let's isolate one variable in one of the equations, I will isolate y on the first one.

y = 8 - 2x

Now we can replace that in the other one to get:

x - 3*(8 - 2x) = - 3

x - 24 + 6x = -3

7x = -3 + 24

7x = 21

x = 21/7 = 3

And the value of y is:

y = 8 - 2x = 8 - 2*3 = 2

Answer:

In the case presented, the range is the difference between the maximum value and the minimum value of the data. The range describes the breadth of the data and how much they vary from the minimum value to the maximum value. Therefore, the range indicates the dispersion of the data.

The statement indicates that the range is 5, which means that the most flights made by students is 5. Since the data has a narrow dispersion, we can conclude that most students have taken a similar number of flights, implying that most students have flown an amount close to the maximum number observed.

Therefore, the option that best describes the dispersion of the data is: "The data has a range of 5, which is a narrow dispersion. This means that most students have taken a similar number of flights."

Answer:

0 < a < 6

or

(0, 6) in interval notation

Step-by-step explanation:

The area of the triangle is
[tex]Area \;A = \dfrac{1}{2}(base \cdot height)\\[/tex]

We are given base = 6 in, height = a and area A < 18 in²

Using the formula for area we get

[tex]A = (1/2)(6 \cdot a) = 3a[/tex]

We know this area is < 18

So 3a < 18

Dividing both sides by 3 gives us
3a/3 < 18/3

a < 6

So height a must be less than 6 inches.
Height cannot be 0 so the lower bound on height is

a > 0

Putting these together we get the rang of a as
0 < a < 6

In Interval notation this is written as (0, 6)

One of the numbers is 21, and the other number is 2.5

What is an algebraic expression?

An algebraic expression is when we combine numbers and words to solve a mathematical problem.

Let's call one of the numbers "x". We know that x is 8 times greater than the other number, which we'll call "y". So we have:

y = x / 8

The product of x and y is 57, so:

x * y = 57

Substituting y = x / 8 into the equation above:

x * (x / 8) = 57

Expanding the right side of the equation:

[tex]x^2 / 8 = 57[/tex]

Multiplying both sides by 8:

[tex]x^2 = 8 * 57[/tex]

Solving for [tex]x^2[/tex]:

[tex]x^2 = 456[/tex]

Taking the square root of both sides:

[tex]x =\sqrt{456}[/tex]

x = 21

So, One of the numbers is 21, and the other number is 21 / 8 = 2.5.

Step-by-step explanation:

To calculate the potential energy of the ball at its highest point, we first need to find the gravitational potential energy of the ball. Gravitational potential energy is given by the equation:

PE = mgh

where m is the mass of the ball, g is the acceleration due to gravity (9.8 m/s^2 on the surface of the earth), and h is the height of the ball above the ground.

At its highest point, the height of the ball is 80 m, so the gravitational potential energy can be calculated as:

PE = m * g * h = m * 9.8 * 80

where m is the mass of the ball.

Since the ball was thrown at an angle of 30 degrees with the horizontal, its initial velocity can be broken down into horizontal and vertical components:

v0x = v0 * cos(30) = 10 * cos(30) = 10 * sqrt(3)/2 m/s

v0y = v0 * sin(30) = 10 * sin(30) = 10/2 m/s

The potential energy of the ball at its highest point can be found by adding the initial kinetic energy of the ball to its gravitational potential energy. The kinetic energy of the ball can be calculated as:

KE = 1/2 * m * v0y^2

where m is the mass of the ball and v0y is the vertical component of its initial velocity.

The total potential energy of the ball at its highest point is given by:

PE = KE + mgh = 1/2 * m * v0y^2 + m * g * h

Substituting in the given values, we find:

PE = 1/2 * m * (10/2)^2 + m * 9.8 * 80

Note: The mass of the ball (m) is not given, so the answer is given in terms of m.
