The Los Angeles area experiences many earthquakes. In 1994, the Northridge earthquake measured 6.7 on the Richter scale. In 2014, Los Angeles experienced an earthquake that measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.

Answers

Answer 1

Answer:

The intensity of the 1994 earthquake was about 40 times the intensity of the 2014 earthquake.

Step-by-step explanation:

1994 earthquake:

6.7I=logI=106.7

2014 earthquake:

5.1I=logI=105.1

Form a ratio of the intensities.

intensity for 1994intensity for 2014

Substitute in the values and divide by subtracting the exponents to find

106.7105.1101.6≈40.

The intensity of the 1994 Northridge earthquake in the Los Angeles area was about 40 times the intensity of the 2014 earthquake.

Find the slope of the line through the points (5, -3) and (5, 4)

Answers

Answer:

Infinity

Step-by-step explanation:

Let one point is x1, y1 (5, -3)

the other is x2, y2 (5,4)

then slope = (y1-y2)/(x1-x2)

=(-3-4)/(5-5)

=-7/0

=Infinity

So slop is infinite

You buy 4 cases of bottled water and 5 bottles of fruit punch for a birthday party. Each case of bottled water cost $2.75, and each bottle of fruit punch coast $1.35. You hand the cashier a $20 bill. How much change will you receive? Hurry! It’s do today!

Answers

Answer:

$2.25

Step-by-step explanation:

Change

= $20 - total price of the items bought

Total price of bottled water

= 4($2.75)

= $11

Total price of fruit punch

= 5($1.35)

= $6.75

Change

= $20 -($11 +$6.75)

= $20 -$17.75

A parallelogram has a base of 9 units and a corresponding height of į units. What is its area?

Do not include units (square units) in your answer.

Answer:

[tex]Area = 9j[/tex]

Step-by-step explanation:

Given

[tex]Base = 9\ units[/tex]

[tex]Height = j\ units[/tex]

Required

Determine the area

Area of parallelogram is calculated as thus:

[tex]Area = base * Height[/tex]

Substitute values for Base and Height

[tex]Area = 9 * j[/tex]

[tex]Area = 9j[/tex]

Hence, the area of the parallelogram whose base is 9 units and height is j units, is 9j

A sequence of steps for solving the equation 3(x - 2) = 4 is shown. Match a property to each blank box to show the reason for each step. Question 6 options: 3(x - 2) = 4 3x - 6 = 4 3x = 10 x = 103 1. Given 2. Distributive Property 3. Addition property of equality 4. Division property of equality

Answers

Step-by-step explanation:

Given the equation;

3(x-2) = 4

A sequence of steps for solving the equation is as shown;

Step 1: Open the parenthesis by applying distributive law to distribute 3 over x and 2 as shown;

3(x-2) = 4

3(x)- 3(2) = 4

3x - 6 = 4

Step 2: Add 6 to both sides of the equation (Addition property)

3x-6+6 = 4+6

3x = 10

Step 3: Division property of equality. Divide both sides by 3;

3x = 10

3x/3 = 10/3

x = 10/3

Calculate the length of PR.
Give your answer correct to 3 significant figures.

Answers

Answer:

The length of PR is 15.8 cm

Step-by-step explanation:

We will solve the question using the cosine rule

In ΔPQR

(PR)² = (PQ)² + (RQ)² - 2(PQ)(RQ)(cos∠Q)

∵ PQ = 17.8 cm

∵ RQ = 26.3 cm

∵ m∠Q = 36°

→ Substitute them in the rule above

∵ (PR)² = (17.8)² + (26.3)² - 2(17.8)(26.3)(cos36)

∴ (PR)² = 316.84 + 691.69 - 936.28(cos36)

∴ (PR)² = 251.0635685

→ Take √ for both sides

PR = 15.8449856

→ Correct it to 3 significant figures

∴ PR = 15.8 cm

The length of PR is 15.8 cm

Step-by-step explanation:

Parallelism: The same slope but different intercepts

1 - Using the slope and point given find the new y intercept

y = 3/2x + b

-1 = 3/2(6) + b

-1 = 18/2 + b

-1 = 9 + b

-9  -9

-10 = b

2 - Write the new equation using the same slope but different y-intercepts

y = 3/2x + b

account will be:
Rs. 2,50,000
Rs.75,000
Rs.4,25,000
Rs. 1,75,000

Answers

Answer:

Rs. 2,50,000

Step-by-step explanation:

When a partnership distributes inventory items (hot asset) to its partners, the basis of the inventory items is used to record the transaction. Only when partnerships distribute assets other than hot assets will the fair market value of the assets be used to record the transaction.

The logic is that inventory items are valued at lower of cost or market value. This means that inventory items are already valued at FMV or cost, whichever is less. If the partnership recorded the transaction using Rs.1,75,000, then it would have to record a loss, and distributions cannot generate losses to a partnership. The only way to record the inventory items at Rs.1,75,000 is that previously the partnership writes down inventory.
