Answer 1

Answer:

41

Step-by-step explanation:

Think about this as a triangle: the measurements given are the legs and the diagonal wanted is the hypotenuse. We can assume this is a right triangle so you could use trig if you wanted but can also use the Pythagorean theorem which is way easier in this case.

\( {a}^{2} + {b}^{2} = {c}^{2} \)

\( {35.7}^{2} + {20.1}^{2} = {c}^{2} \)

Rounding to the nearest whole number:

\(c = 41\)

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

Please help me. X/6 ≥ 7. I also need to know how this would be graphed thank you.

Answers

Answer: The inequality solves to x ≥ 42

The graph is shown below

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

Explanation:

We have some unknown number x, and we're dividing by 6 to form the fraction x/6. That result is 7 or larger which means we write x/6 ≥ 7

To solve for x, we undo the division. We'll multiply both sides by 6. That's how we get to x ≥ 42

The graph will involve a number line. Plot a closed filled in circle at 42 on the number line. Shade to the right. This visually represents any number that is 42 or larger. The endpoint 42 itself is included in the solution set.

Side note: We would use an open circle if we didn't have the "or equal to" portion for the inequality sign.

the first one i think


Answer:

second answer: y = 5x + 120; $180

Step-by-step explanation:

he starts with $120.

so, whatever else he does per month, there will always be the $120 starting amount to be added.

so, the third and the fourth answers are out.

then think : $5 every month.

that is how much after 2 months ? 2×5 = $10.

how much after 3 months ? 3×5 = $15.

so it has to be an equation that contains 5x (5 times the number of months).

combining both thoughts :

y = 5x + 120

now let's use x = 12 (for 12 months = 1 year).

5×12 + 120 = 60 + 120 = $180.

yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data
