Mathematics Middle School

Ight everyone I'm in need of some help here.
The info you'll need: The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.

On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

What is the elevation of the surf shop?
What was the distance between the deck and the ocean’s surface at 1 p.m.? Which was higher, the deck or the ocean?

Gabby bought a backpack and 3 notebooks for $40.66. What is the total tax if the rate is 8%?

Answers

Answer:

It's $3.25 in tax

Step-by-step explanation:

Answer:

$3.24

Step-by-step explanation:

You would first have to figure out the cost of each notebook with tax so you would divide 40.66 by 3

40.66/3 = 13.55

So each notebook costs $13.55 with tax. Now, I multiplied 13.55 by 0.08. I would multiply it by 0.08 because 8% in decimal form is 0.08.

13.55*0.08 = 1.08

I got the answer 1.08. 1.08 is the tax for each notebook so I would multiply it by 3 to figure out the total tax.

1.08*3 = 3.24

Hence, the total tax is $3.24.

Hope this helped :-)

Hector is rewriting the expression 7 Superscript 11 in expanded form. How many terms will be multiplied in his rewritten expression?
A.2
B.7
C.11
D.12

Answers

Answer:

Step-by-step explanation:

C. 11
Step-by-step explanation:
We know that Hector is writing the expression in the expanded form.
Now, = 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7
i.e. 7 is multiplied 11 times in order to obtain the result .
Thus, we see that there are 11 terms being multiplied in the expanded form.
Hence, option C is correct.

Use the table to answer the following questions.

Time (hours) Distance (miles)
2 90
3 135
5 225
6 270
1. Find the constant of proportionality.

2. Use the constant of proportionality to write a unit rate for the data in the table.

3. Write an equation to represent the relationship between time, t, and distance, d.

Answers

Answer:

Sure, here are the answers to your questions:

The constant of proportionality is 45. This is because the ratio of distance to time is always 45. For example, 90/2 = 45, 135/3 = 45, 225/5 = 45, and 270/6 = 45.

The unit rate is 45 miles per hour. This is because the constant of proportionality is 45, and the units of time are hours and the units of distance are miles.

The equation that represents the relationship between time, t, and distance, d, is d = 45t. This is because the constant of proportionality is 45, and the equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality.

Here are the steps that I used to solve the problem:

I first looked at the table and noticed that the ratio of distance to time was always the same. This is a clue that the relationship between distance and time is proportional.

I then calculated the constant of proportionality by dividing the distance by the time for each pair of values. For example, I divided 90 by 2 to get 45, 135 by 3 to get 45, 225 by 5 to get 45, and 270 by 6 to get 45.

I then used the constant of proportionality to write a unit rate. The unit rate is the constant of proportionality divided by the units of time. In this case, the constant of proportionality is 45 and the units of time are hours. Therefore, the unit rate is 45 miles per hour.

I then used the constant of proportionality to write an equation. The equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality. In this case, the constant of proportionality is 45, so the equation is d = 45t.

Step-by-step explanation:

Students at the college are allowed to work on campus no more than 20 hours per week. The jobs that are available pay different rates, starting from $8.75 an hour. Students can earn a maximum of $320 per week.

Write at least two inequalities that could represent the constraints in this situation.

let h = hours worked
let r = the hourly rate in dollars

Answers

H is less than it equal to 20
R is greater than or equal to 8.75

The required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

College students are allowed to work on campus for no more than 20 hours a week. The listed jobs pay a range of rates beginning at $8.75 per hour. Students can earn up to $320 every week.

Let h represents hours worked

Let r represents the hourly rate in dollars

According to the given situation, the required inequalities would be as:

h ≤ 20 and r ≥ 8.75

Therefore, the required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

It controls which molecules enter and leave the cell. The cell membrane is selectively permeable, which means it allows certain substances through and not others. One way that substances enter and leave the cell is through diffusion, the movement of particles from higher concentration to lower concentration. For example, if the concentration of salt molecules is higher inside the cell than outside, salt particles will move out of the cell. Diffusion is a type of passive transport, a movement of particles that does not require energy to occur.
