Mr.Jessup, an airplane pilot, flies 1,450 miles a day. How many miles will he fly in 8 days? Why?

The equation written is: x + 18 + x = 84

The lengths of each piece of the cable are: 33 meters and 51 meters.

To write an equation, let the unknown quantity be represented as a variable, which would be used in creating an algebraic expression.

For example, we are given the following:

Length of a cable = 84 meters

The length of one the pieces that the cable is cut into is represented as x.

The second pieces = x + 18 meters.

The equation that would be created for this problem would be:

x + 18 + x = 84

Solve for x:

2x + 18 = 84

2x = 84 - 18

2x = 66

2x/2 = 66/2

x = 33

The length of one of the pieces = 33 meters

Length of the second piece = x + 18 = 33 + 18 = 51 meters.

A 3:2 image ratio refers to the proportion of the width to the height of an image or screen. It means that for every 3 units of width, there are 2 units of height.

The aspect ratio 3:2 is commonly used in digital photography, particularly for DSLR cameras and some mirrorless cameras.

In photography, the 3:2 aspect ratio is considered a standard format, it's the same as the traditional 35mm film frame, it's also the same as the aspect ratio of most modern digital cameras. It allows photographers to capture a wide range of scenes and subjects, and it's also a good option for cropping and printing photos.

For example, if an image's resolution is 3000x2000 pixels, it means that it has a 3:2 aspect ratio. The width of the image is 3000 pixels and the height is 2000 pixels, so 3000/2000 = 3/2

It's worth noting that the aspect ratio of 3:2 is a compromise between the wider aspect ratio of 16:9, used for video and some photography, and the taller aspect ratio of 4:3, used for more traditional photography.

The area of the triangle is 54 square centimetres, which is calculated by multiplying the base (12 cm) and height (9 cm) and dividing by 2.

A = (12 cm * 9 cm) / 2

A = (108 cm²) / 2

A = 54 cm²

The area of a triangle is calculated by multiplying the base of the triangle and its height, and then dividing the result by 2. To calculate the area of the triangle with a base of 12 cm and a height of 9 cm, first the base and height must be multiplied together. 12 cm multiplied by 9 cm equals 108 cm². Then, the result of the multiplication, 108 cm², must be divided by 2. 108 cm² divided by 2 equals 54 cm². Therefore, the area of the triangle is 54 cm². To summarize, the area of a triangle is found by multiplying the base and height of the triangle, and then dividing the result by 2. In this case, the area of the triangle with a base of 12 cm and a height of 9 cm is 54 cm².

Answer:

Step-by-step explanation:

given the system of equations

x + 3y = 76 → (1)

x + y = 36 → (2)

1

subtracting (2) from (1) term by term will eliminate x

(x - x) + (3y - y) = 76 - 36

0 + 2y = 40

2y = 40 ( divide both sides by 2 )

y = 20

3

substitute y = 20 into either of the 2 equations and solve for x

substituting into (2)

x + 20 = 36 ( subtract 20 from both sides )

x = 16

4

substitute the values for x and y into the equations and if both sides are equal then they are the solution

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

x –2 0 1 2 3

h(x) 0 –12 0 8 0

The x-intercepts are where y = 0

So, we have

x = -2, x = 1 and x = 3

The multiplicity is 1

So, we have

h(x) = (x + 2)(x - 1)(x - 3)

Expand

= (x + 2)(x^2 - 4x + 3)

This gives

= x(x^2 - 4x + 3) + 2(x^2 - 4x + 3)

So, we have

Answer: a. In this situation, 0 likely represents sea level or the baseline from which water levels are measured.

b. To find the average water level relative to high tide, you need to take the average of high tide and low tide.

Since high tide is 5 feet higher than low tide, you can assume that low tide is 0 ft. Therefore, the high tide is 5 ft.

The average of two values is the sum of the values divided by the number of values. So average of 0ft and 5ft is (0+5)ft / 2 = 2.5 ft.

Therefore, an integer that represents the average water level relative to high tide would be 2.5 ft.

It's worth noting that relative to high tide means how much the average water level varies (higher or lower) from the high tide, so the answer was not an integer in this case.

Step-by-step explanation:

1.y = x * (1-0.4)

2.y = x - 0.4x

3.x = y / (1-0.4)

4.x = y + 0.4y

The equation 1 and 2 correctly represent the situation. In the first equation, we are multiplying the initial amount of water (x) with (1-0.4) which is the percentage of the water that is remaining after drinking 40% of it. In the second equation, we are subtracting 0.4x from x, which is equivalent to multiplying x by (1-0.4).

The equation 3 and 4 are not correct, as they are trying to calculate the initial amount of water from the remaining amount, but it's not possible to know the initial amount once it has been consumed.

You have 0.6X amount water remaining.

The amount of water remaining in the water bottle is X minus 40%. This means that if you had X amount of water at start you now have 60% of X left.  That is, you have 0.6X amount of water remaining.

A triangle is said to be equilateral if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.

A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.

Solutions can be divided into supersaturated, unsaturated, and saturated solutions based on how well the solute dissolves in the solvent.

Supersaturated solution: The excess solute will crystallize quickly in a supersaturated solution because it contains a lot of solute at a temperature where it will be decreased.

Unsaturated solution: When a solvent can dissolve any more solute at a specific temperature, the solution is said to be unsaturated.
