Using the following national income accounting data, compute (a) GDP, (b) NDP, and (c) NI. All figures are in billions. Category Value Compensation of employees $196.2 U.S. exports of goods and services 19.8 Consumption of fixed capital 11.8 Government purchases 59.4 Taxes on production and imports 14.4 Net private domestic investment 52.1 Transfer payments 13.9 U.S. imports of goods and services 16.5 Personal taxes 40.5 Net foreign income 2.2 Personal consumption expenditures 219.1 Statistical discrepancy 0.0 Instructions: Round your answers to one decimal place. a. GDP = $ billion b. NDP = $ billion c. National Income = $ billion

Answers

Answer:

(a) GDP = $333.9 billion

(b) NDP = $322.1 billion

(c) NI = $307.7 billion

Step-by-step explanation:

(a) Compute GDP

This can be computed using the following formula:

GDP = Gross Domestic Product = Personal consumption expenditure + net private domestic investment + government purchases + (US exports of goods - US Imports of goods) ......... (1)

Substituting the values into equation (1), we have:

GDP = $219.1 + $52.1 + $59.4 + ($19.8 - $16.5) = $333.9

Since all figures are in billions, we have:

GDP = $333.9 billion

(b) Compute NDP

This can be computed using the following formula:

NDP = Net domestic product = GDP - Consumption of fixed capital ................... (2)

Substituting the values into equation (2), we have:

NDP = $333.90 - $11.8 = $322.1

Since all figures are in billions, we have:

NDP = $322.1 billion

(c) Compute NI

This can be computed using the following formula:

NI = National Income = NDP - Taxes on production and imports  - Statistical discrepancy ........... (3)

Substituting the relevant values into equation (3), we have:

NI = $322.1 - $14.4 - $0.0 = $307.7

Since all figures are in billions, we have:

NI = $307.7 billion

What is the width of Averi's area model? (See picture)

Answers

Answer:

Width = x² + 5x - 4

Step-by-step explanation:

By the definition of an area model,

Area = Width × greatest common factor

Since, Area = 4x² + 20x - 16

And greatest common factor = 4

4x² + 20x - 16 = 4(Width)

By dividing both the sides of the equation by 4,

[tex]\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}[/tex]

x² + 5x - 4 = Width

Therefore, width = (x² + 5x - 4) will be he answer.

Andrew and Kate have $30 to spend on dinner tax and gratuity at Moe's restaurant tax is 6% and they will give a 50% tip on the total bill after taxes their dinner cost $21 which statement correctly explains whether Andrew and Kate have enough money to pay their bill ​

Answers

Given the money which the Andrew and Kate have to spend on dinner is $30.
Tax is 6%
Now we have to find the total cost of dinner. If the cost of dinner is less then the money that the Andrew and Kate have then we can say Andrew and Kate have enough money to pay their bill.
Tax rate = 6%
Total tax= (Tax apply)(dinner cost)
= 0.06\times21
= $1.26
Dinner cost after tax is $21+$1.26
=$22.26
Now it is given that they will give 15% tip on the total bill after taxes
∴ Amount of tip given = 15\% \times 22.26
⇒ = $3.339
Total bill of dinner = dinner cost+Tax+Tip
= $22.26+$3.339
= $25.599
Hence total bill of dinner is less than the money the have to spend.
⇒ Andrew and Kate have enough money to pay their bill.

An object is launched on the moon at 16 feet per second (f/s) from a 1152-foot tall tower. The equation for the object's height s at time t seconds after launch is
s(t) = -16t^2 + 16t + 1152, where s is in feet. When does the object strike the moon’s surface and why?

Answers

Answer:

0.5seconds later

Step-by-step explanation:

Given the height modeled by the equation:

s(t) = -16t^2 + 16t + 1152

The velocity of the object at the moon surface is zero

ds(t)/dt = 0

ds(t)/dt = -32t + 16

0 = -32t + 16

32 t = 16

t = 16/32

t = 1/2

t = 0.5seconds

Hence the object strikes the moon surface 0.5seconds later

Answers

Answer:

[tex]\frac{1}{8} = \frac{2}{16} < \frac{4}{24}[/tex]

Step-by-step explanation:

Since [tex]\frac{1}{8}[/tex] is already simplified, we do not need to change it in any way. Comparing it with [tex]\frac{2}{16}[/tex], which after simplifying is [tex]\frac{1}{8}[/tex], we can see that they are the same. Therefore, [tex]\frac{1}{8} = \frac{2}{16}[/tex].

Now. we compare [tex]\frac{2}{16}[/tex] with [tex]\frac{4}{24}[/tex]. We have already established that [tex]\frac{2}{16}[/tex] is [tex]\frac{1}{8}[/tex], so all we have to do is to simplify [tex]\frac{4}{24}[/tex] and compare it with [tex]\frac{1}{8}[/tex]. Simplifying [tex]\frac{4}{24}[/tex], we get [tex]\frac{1}{6}[/tex], which is larger than [tex]\frac{1}{8}[/tex]. Therefore, [tex]\frac{2}{16} < \frac{4}{24}[/tex].
