does 3x-y=4 and 6x-2y=8 have a solution?

Answer:

Total Population = Young & Institutionalized + Working Age Population

Working-Age Population = Labor Force + Not in the Labor Force

Labor Force = Employed + Unemployed

Total population = 400

Working Age Population = 300

Young & Institutionalized = 100

Not in Labor Force = 100

Labor Force = 200

Employed = 150

Unemployed = 50

Employment-population ratio = (Employed ÷ Working Age Population) x 100%

                                                 = (150 ÷ 300) × 100%

                                                 = 50%

Labor force participation rate = (Labor Force ÷ Working Age Population) x 100%

                                                 = (200 ÷ 300) × 100%

                                                 = 66.7% (nearest tenth)

Unemployment rate = (Unemployed ÷ Labor Force) x 100%

                                  = (50 ÷ 200) x 100%

                                  = 25%

If their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

a. Taxable income:

Taxable income=Gross income - Total taxes due

Taxable income=$63,000-$6,847.50

Taxable income=$56,152.5

b. The marginal tax rate for taxable income  under the income bracket of of $40,526 to $86,375 is 22%.

c. Effective tax rate:

Effective tax rate = Total taxes due/ Taxable income×100

Effective tax rate =$6,847.50/$56,152.5×100

Effective tax rate =10.869%

Effective tax rate =10.87% (Approximately)

Inconclusion if their total taxes due are $6,847.50, their taxable income is: $56,152.2, marginal rate is 22% and the effective tax rate is 10.87%.

Answer:

1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3

It takes more 1/9 than 1/6 to make a fraction equivalent to 1/3.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

To make a fraction equivalent to 1/3, we need to multiply both the numerator and the denominator by the same non-zero constant. Let's call this constant "x". Therefore, the equivalent fractions are:

1/3 = (x1)/(x3)

To compare how many 1/9s and 1/6s are needed to create this fraction, we need to find the value of "x" that will make the denominators of 1/9 and 1/6 equal to the denominator of 1/3, which is 3.

For 1/9, we can find x as follows:

1/9 = (x1)/(x9)

Multiplying both sides by 3, we get:

3/9 = (x3)/(x9)

Simplifying, we get:

1/3 = x/9

Multiplying both sides by 9, we get,

x = 3

Therefore, to make a fraction equivalent to 1/3 using 1/9, we need to multiply both the numerator and denominator by 3.

Now let's look at 1/6. We can find x as follows:

1/6 = (x1)/(x6)

Multiplying both sides by 2, we get:

2/12 = (x2)/(x12)

Simplifying, we get:

1/6 = x/12

Multiplying both sides by 12, we get:

x = 2

Therefore, to make a fraction equivalent to 1/3 using 1/6, we need to multiply both the numerator and denominator by 2.

x=9

y=3√3

Use trig ratios

Answer:

x = 3sqr3, y = 9

Step-by-step explanation:

Use SOH CAH TOA, to solve this.

Here I know the hypotenuse, so I could use either SOH either CAH or both to find the 2 unknowns.

To find y, I would use SOH, which is Sin(angle) = opposite/hypotenuse.

When I rearrange it, I get Sin(angle)*hypotenuse = opposite. Now let's fill in with the values to give:

Sin(30)*6sqr3 = 3sqr3

And then to find x, let's use CAH, which is Cos(angle) = adjacent/hypotenuse.

Rearrange it to get Cos(angle)*hypotenuse = adjacent. This gives us a side x with a value of:

Cos(30)*6sqr3 = 9

I dont understand

The Consumer Price Index for the year 2 be 116.11.

This is calculated by adding together a sampling of product prices from a previous year.

We then add together the current prices of the same products and divide the total of current prices by the old prices, then multiply the result by 100.

Given data

Year 1 = $9

Year 2 = $10.45

Year 2 / Year 1 = $10.45 / $9.00

Year 2 / Year 1= 1.6111

CPI for year 2 = 1.61 x 100

CPI for year 2 = 116.11

Therefore, the Option D is correct.

Answer:

c=-2.5s

Step-by-step explanation:

The equation modeling the change in elevation c after s seconds is

c = -2.5s

Given,

A mountain climber descends a cliff at a rate of 2.5 ft/second.

We need to write an equation modeling the change in elevation c after s seconds.

Elevation means going up so we take it as a positive distance.

Descent means going down so we take it as a negative distance.

Find the rate at which the climber descents.

2.5 ft = 1 second

Find the equation that represents the descents c in seconds.

We have,

2.5 ft = 1 second

So,

s x 2.5 ft = s x 1 seconds

2.5 s ft = s seconds

This means,

In s seconds we will have a 2.5s distance descended.

We can write this as an equation:

c = change in elevation

c = - 2.5s

Thus the equation modeling the change in elevation c after s seconds is

c = -2.5s

Step-by-step explanation:

Since there are 6 packs in all, and a total of 72 cards, we can multiply 6×12=72

There were 12 cards in each pack if they have 72 cards in all.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
