Trina is closer to the surface of the ocean. She will not fly higher than Jessie did.

Consider the provided information.

The distance is the absolute value of a number.

Part (A) : It is given that Trina went scuba diving and reached an elevation of -85.5 meters, which is below sea level.

That means the distance she covers is: |-85.5| = 85.5 meters

Thus Trina covers 85.5 meters.

Jessie went hang gliding and reached 87.9 meters which is above sea level.

That means the distance she covers is: |87.9| = 87.9 meters

We know that 85.5 < 87.9

So, we can say that Trina is closer to the surface of the ocean as she covers less distance.

Part (B) : Trina wants to hang glide at the same number of meters above sea level as she scuba dived below sea level.

That means she will hang the glide at a height of 85.5 meters.

As we know 85.5 < 87.9

Thus, she will not fly higher than Jessie.

The length of the original sides of the rectangle are 72m and 24m.

The area of a rectangle formula is used to calculate the area occupied by the rectangle within its boundaries. A rectangle's area is calculated by multiplying its length and breadth.

Given:

One side is 3 times as long as the other in a rectangle.

Let the length of the rectangle be 3x and the breadth of the rectangle be x.

Area of original rectangle = length × breadth

                             = 3x² m²

Now, the longest side is extended by 4m.

Length of rectangle = 3x + 4

Area of rectangle = length × breadth

                             =  x(3x + 4) m²

It is given that this area will be 96 square meters larger than the former.

So, x(3x + 4) - 3x² = 96

⇒ 3x² + 4x - 3x² = 96

⇒ 4x = 96

⇒ x = 24 m

Original length of the rectangle = 3x = 3×24 = 72m

Therefore, the original length of the rectangle is 72m and the original breadth of the rectangle is 24m.

Subtract 146 from both sides:

[tex]x+146-146=546-146\\[/tex]

[tex]x=400[/tex]

Answer:

x = 400

Step-by-step explanation:

x + 146 = 546

We need to subtract 146 on both sides.

146 - 146 is equal to 0 so we cancel out. 546 - 146 is equal to 400.

So now x is alone and we have our answer.

If we reflect a triangle in a line, translate a triangle, rotate a triangle, and reflect it in a point result in an image that will be congruent to the original( pre-image) triangle.

This is a problem from triangular geometry. We can solve this problem by following a few steps.

Here a triangle ABC is given and the triangle is at first reflected and then translated, thereafter it rotates and is later reflected.

After all, these processes the value of ∠A, ∠B, and ∠ C remains the same as usual concerning ∠A''', ∠B''', ∠ and C'', as they just changes coordinates not geometric structures.

After all these processes the length of the triangle AB, AC, BD, and A'''B''', B'''C''', C'''A''' remains the same as usual.

∵ We can conclude that ΔABC ≅ ΔA'''B'''C'''

( As AB = A'''B''', BC = B'''C''', ∠ABC = ∠ A'''B'''C''' )

If the sum of two angles is 180 then the angles are supplementary.This is true.

Supplementary angles are those that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles since the sum of 130° and 50° equals 180°.

If the total of two angles is 180 degrees, they are considered to be supplementary angles since they form a linear angle when combined. If the total of two angles is 90 degrees, they are considered to be complimentary angles since they produce a right angle when combined.

If two angles add up to 180 degrees, they are considered to be supplementary angles in geometry. For example, if A + B = 180°, A and B are referred to as supplementary angles. When supplementary angles are combined, they always yield a straight angle (180 degrees).

Given the circle, we can see the following facts:

Diameter= 24 ft ----> radius= 12 ft

Total arc length = 360°

The arc of a semi-circle is equal to 360/2 = 180 degrees

The red labeled arc is given by the difference between 360, the other 60 degrees and the semi-circle,

360° - 180° - 60° = 120°

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line = (1, -2)

And, The slope of the line = 10

Now,

Since, The equation of line in point-slope form is;

⇒ y - y₁ = m (x - x₁)

Where, (x₁ , y₁) is the point on the line and m is slope of the line.

Hence, The equation of line in point-slope form passing through the points (1, -2)  with slope 10 is;

⇒ y - y₁ = m (x - x₁)

⇒ y - (-2) = 10 (x - 1)

⇒ y + 2 = 10x - 10

⇒ y = 10x - 10 - 2

⇒ y = 10x - 12

Thus, The equation of line in point - slope form will be;

⇒ y + 2 = 10 (x - 1)

The rest of the driver paid with 20 p coins.

So the number of 20 p coins is:

320 - 176 = 144

Since £1 and 20 p need 6 coins of 20 p, the number of drivers who paid only for 20 p coins is:

144 / 6 = 24

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. It is not necessary for the angle to be in Euclidean space if it lies in the plane. Angles are referred to as dihedral angles if they are created by the intersection of two planes in a space other than Euclidean. The sign "" is used to denote angles. The Greek letter,,, etc. can be used to represent the angle measurement between the two rays. If different types of angles, such as a positive angle and a negative angle.

Positive Angle: If angle goes in counterclockwise, then it is called a positive angle.

Negative Angle: If angle goes clockwise direction, then it is called a negative angle.

A mathematical sentence that uses the equal sign, =, to show that two expressions are equal is known as an equation. Look for key words or phrases such as "is," "the same as," or "equals" to determine where to place the equal sign when writing a word sentence as an equation. Make an equation out of the word sentence.

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation. Linear equations are classified into three types: point-slope, standard, and slope-intercept.

Answer:

No

Step-by-step explanation:

======================================================

Explanation:

x = number of hours

y = total cost

The equation is y = 25x+250 since 250 is the initial cost, aka y intercept, and 25 is the slope telling us how much the cost goes up per hour (aka rate of change).

I recommend making a table of values to help see how/why that equation works out.

Plug in y = 1275 and isolate x.

y = 25x+250

1275 = 25x+250

1275-250 = 25x

1025 = 25x

25x = 1025

x = 1025/25

x = 41 hours

----------------

Check:

If the customer rents the car for 41 hours, then they pay 25*41 = 1025 dollars on top of the initial fee of $250.

The total cost is therefore 1025+250 = 1275 dollars to confirm the answer.
