Activity B:

Low-pressure systems

Get the Gizmo ready:

Click New until you see a low-pressure system, represented by the symbol L.

Check that Show Mobile Station B data and Show land are on.

Question: What weather patterns are associated with low-pressure systems?

Observe: Note how the air pressure changes as you move Station B towards the center of the low-pressure system.

What do you notice?

Why do you think this is called a low-pressure system?

### Answers

**Answer:**

clouds

**Step-by-step explanation:**

Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.

I observe that when moving closer to station B the elevation as well as how close it is to the clouds is making the pressure more/less. also there could be more clouds there making the pressure more high or low.

Areas where the air is warmed often have lower pressure because the warm air rises. These areas are called low pressure systems. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

**Step-by-step explanation:**

Turn 27.3 days into hours then multiply the hours(23.7D) by the big number for your answer

**Answer:**

Do (3.68 x 10^3) x 27.3 for the distance

Distance = speed x time

Distance (km per day) = (3.68 x 10^3) x 27.3

### Answers

**Answer:**

-66/15

**Step-by-step explanation:**

Convert all of them to improper fractions:

26/3 - 19/5 + 139/15

Using the rule of BODMAS;

We will add first before we subtract.

26/3 - (19/5 + 139/15)

L.C.M of 5 and 15 is 15

26/3 - (13×19)+(1×139)/15

{26/3 - 196/15}

Now we will subtract

LCM of 3 and 5 is 15

(5×26) - (1×96)/15

=130 - 96/15 = -66/15.

Savings

The graph shows the savings in Andre’s bank account.

### Answers

1. 20/4 = 5

this is because it’s rise over run for slope.

2. the meaning is that over time spent working, savings will add up.

The **slope** of this line is **$5**. This means Andre is saving **$5 per week** in bank.

What is the general equation of a straight line?

The **general equation** of a straight line is -

**y = mx + c**

Where -

**[m] **is the **slope** of the line.

**[c] **is the **y - intercept**.

Given is a graph showing **savings** in Andre’s bank account.

The **coordinates** through which the line passes are - **(0, 40) **and** (4, 60)**

Then the **slope** of this line will be -

**m** = (60 - 40)/(4 - 0) = 20/4 = **5**

A slope of **$5** means that Andre is saving **$5 per week** at bank.

Therefore, the **slope** of this line is $5. This means Andre is saving **$5 per week** in bank.

Use the Pythagorean theorem to find the length of side FD.

### Answers

**Answer: i think its 9 but sorry if I'm wrong I'm only in 4th grade**

**Step-by-step explanation:**

It’s 10

In triangle ABC:

3^2+4^2= c^2

9+16=25

Square root of 25 is 5, so hypotenuse of triangle ABC is 5.

For triangle DEF, not that the given side is 8, which twice the amount of four. To find the other adjacent side of the triangle, we will multiply 3 by 2 because that is what we did with the 4. by doing this we can conclude that our other side is of the triangle is 6 Then, we have this pythagorean theorem to solve for FD:

8^2+6^2= C^2

64+36=100

C^2=100

The square root of the 100 is 10, therefore the length of side FD is 10.
