The total distance traveled is 46 miles.

Distance Traveled:

Distance traveled is the path covered by a body to get from a starting point to an endpoint in a certain period of time, at a certain velocity. Time and velocity play a major role in measuring the distance traveled. The distance travel formula is: d = v x t

To determine the total distance you have traveled, you will need to add up all the distances you have driven in each direction.

You drove 10 miles north, 14 miles east, 16 miles north, and 2 miles east, 4 miles north.

10 miles north + 14 miles east + 16 miles north + 2 miles east + 4 miles north = 46 miles

So, you have traveled 46 miles.

Solving the 2 equations will give us the value of x to be -14 and that of y to be 33.

Here we have two equations

2x + y = 5 and 3x - 2y = 4

Now we will use the substitution method to solve the equations

The first equation is

2x + y = 5

or, y = 5 - 2x                                                         [1]

Let 3x - 2y = 4 be equation 2

Substituting the value obtained in equation [1] in [2] we get

3x - 2(5 - 2x) = 4

or, 3x - 10 + 4x = 4

or, x = -14                                                               [3]

Substituting the value of x obtained in equation [3] to equation [1] we get

y = 5 - 2(-14)

or, y = 5 + 28

or, y = 33

Hence, x = -14 and y = 33

What is the solution of the equations 2x + y = 5 and 3x - 2y = 4?

Answer:

Step-by-step explanation:

plug in a 0 for y and simplify the equation

because 0*(constant of y)=0, so

x*(constant of x)=something, so

something/(constant of x)=x

ans is (x, 0)

The expression for the width is x (b) The perimeter of the rectangle in terms of x is x +8

You should understand that the perimeter of a rectangle is the distance round the rectangle

The given parameters that will help us to understand and solve the question are

Area = length * width

This implies that 2x +24 =4x

Collecting like terms =4 = 4x-2x

2x = 24

Therefore x = 24/2 = 12

b)  The perimeter is = L+W+L+W

Perimeter = 2L+w

Where W =x

Perimeter = 2(2x+24) +2(x)

The perimeter = 4x+48 +2x

Therefore the perimeter = 6x+48 or x+8

Note that the expression when simplified translates to x = -6 (Option 1)

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms.

√(x + 14) - √2x + 5) = 1

To solve this, we must square all elements on both sides of the equation. That is:

√(x + 14)² -  √(2x + 5)² = 1²

⇒ x + 14 + 2x + 5 = 1

Collect like terms to arrive at:

Rate does Lynn's cost increase for every additional mile she drives will be $0.25

The following is the linear relationship between the two variables:

where m and k are evaluation-needed constants

Find m: We'll determine the angle of the line connecting the points (480, $380) and (800, $460).

Line slope (m) equals $0.25 per mile

Consider one of the two positions and enter (480,$380) in Eq 1 to find k.

k = 380 - 0.25(480) = $260

The line's equation is C f(d) = 0.25*d + 260.

Jacob's speed in kilometers per hour is equal to 8/5 kilometers per hour.

In Science, speed can be defined as the distance covered by a physical object or body per unit of time. This ultimately implies that, speed is a scalar quantity because it has magnitude but no direction.

Mathematically, the speed of a physical object or body can be calculated by using this formula;

Speed = distance/time

Substituting the given points into the speed formula, we have the following;

Speed = 2/5/(1/4)

Speed = 2/5 × 4/1

After solving, the solution of the pair of equation is (-1, 0).

In the given question, we have to find the solution of the system of equations y = 4x + 4 and y = -3x - 3.

The given equations are:

y = 4x + 4.....................(1)

y = -3x - 3.....................(2)

Now putting the value of y from equation 1 to the equation 2

4x + 4 = -3x - 3

Subtract 4 on both side, we get

4x = -3x - 7

Add 3x on both side, we get

7x = -7

Divide by 7 on both side, we get

x = -1

The percent decrease in price for booking early for a spring break vacation package is 16.5%.

This was calculated by taking the amount of money saved ($35) and dividing it by the original price of the package ($209.99). Then, the resulting decimal was multiplied by 100 to convert it into a percentage.

Mathematically, the calculation looks like this:

(35/209.99) ×100 = 16.5%.

The 16.5% decrease in price is a substantial savings and could be used to purchase additional items or activities during the vacation. Booking early is often a great way to save money on vacation packages, since travel agents and companies often lower the prices to incentivize travelers to book in advance.

It is important to remember, however, that the savings may not always be 16.5%. Depending on the travel agent or company, the percentage of savings may vary. Additionally, some packages may not offer any savings at all. Therefore, it is important to do research and compare different packages before booking.

So, 40% of students don't like swimming.

We know that 60% of students like swimming, and 40% of students like dancing. We also know that 20% of students that like swimming also like dancing.

First, we can find the number of students that like swimming and dancing by multiplying the percentage of students that like swimming by the percentage of students that like dancing and also like swimming:

20% * 60% = 12%

This means that 12% of students like both swimming and dancing.

To find the percentage of students who don't like swimming, we can subtract the percentage of students who like swimming from 100%.

100-60 = 40%

So, 40% of students don't like swimming.

It's important to note that if the problem had provided a total number of students this information would have been useful to calculate the exact number of students who don't like swimming.

$1200 was invested at a mutual fund of 6% profit while $2000 was invested at a mutual fund of 4% profit

An equation is an expression showing the relationship between numbers and variables.

Let x represented the money at 6% profit and y represent the money at 4% interest. A total of $3200 was invested, hence:

x + y = 3200    (1)

If the investor's total profit was $152, therefore:

0.06x + 0.04y = 152         (2)

a. On the 13th day the company sold the same number of each player.

a. The day on which the company sold the same number of players can be calculated by equating the values of y that we have ;

y = 191x-32 and y = -x² + 200x + 20

Equating both, we have;

191x-32 = -x² + 200x + 20

⇒x² -200x + 191x-20-32 = 0

⇒x²-9x-52 = 0

⇒x²-13x + 4x -52 = 0

⇒x(x-13)+4(x-13) = 0

⇒(x-13)(x+4) = 0

⇒x = 13 or -4

as days cannot be negative, so we choose only x = 13

This means that the company sold equal numbers of players on the 13th day.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take points from the Graph (5, 0) and (5, 4).

Slope of a line = m = tanθ

where θ is the angle made by the line with the x−axis.

For a line parallel to y−axis ,θ= π/2.

A 30-60-90 triangle is a special type of right triangle that has angles of 30 degrees, 60 degrees, and 90 degrees. It has the following properties:

The side opposite the 30-degree angle is half the length of the hypotenuse (the side opposite the 90-degree angle).

The side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle.

To find the sides of a 30-60-90 triangle, you can use these properties.

If you know the length of the hypotenuse (the side opposite the 90-degree angle), you can find the length of the other two sides using the following formulas:

The side opposite the 30-degree angle: hypotenuse / 2

The side opposite the 60-degree angle: (√3) * (hypotenuse / 2)

If you know the length of one of the other two sides, you can use the above formulas to find the length of the hypotenuse and the other side.

For example, if you know the length of the side opposite the 30-degree angle, you can find the length of the hypotenuse by multiplying it by 2 and the length of the side opposite the 60-degree angle by multiplying it by √3

In summary:

The hypotenuse is always twice the length of the shorter leg.

The longer leg is √3 times the length of the shorter leg.

The hypotenuse is always the longest side in a 30-60-90 triangle.

Base angles of an isosceles triangle are equal.

Base is bisected by a line from top (vertex) of the triangle straight down to form a right angle.  Base, 100 cm, has 2 equal segments, 50 cm each.

Find h, height of the triangle:

h² = 60² - 50²

h = √1100 = 33.17

sin(f) = 33.17/60 = 0.553

m∠f = sin⁻¹(0.553) = 33.56°
