The price of a mansion is $1.00 in 2013.

What is difference between a nominal and real variable?

Nominal variables are expressed in money or dollar terms, whereas the real variable compares the wage earned per hour to the basket of goods or services that it can purchase.

In comparing the wage earned per hour to 2 comic books, since the two would cost $12,that explains real variable, which is not required in this case.

However, comparing the the wage of $12 per hour to the price of mansion, which is $1 per one, indicates nominal variable.

In essence, the correct option in this case is that price of a mansion is $1.00 in the year 2013.

Answer:

130

Step-by-step explanation:

let the inside value be,x

x+30°+20°=180°(Being sum of interior angle of triangle)

or,x+50°=180°

or,x=180°-50°

or,x=130°

Now,

let the exterior angle be,a

a=x(VOA)

a=130°

Therefore the value of a is 130°.

Answer: Plant B produced 4000 panels

Step-by-step explanation: Let the number of panels produced by plant A = a and the number of panels produced by plant B = x. In total, we have 3000 + x.  Now for the defective panels. 10% of plant a + 3% of plant b = 6% of both a and b. 300 + 3/100(x) = 6/100(3000 + x). 300 + 0.03x = 180 + 0.06x. Now, we simplify. 300 - 180 = 0.06x = 0.03x. So, 120 = 0.03x and 40 = 1% of x. This means x = 4000. So, therefore, Plant B produced 4000 panels. We can check our work by using the value of x we got. 4000 + 3000 = 7000. 6% of 7000 = 420. 120 = 3% of 4000. 120 + 300 = 420 so the answer we got is correct. Hope this helped

Simple interest is determined as the principal multiplied by the interest rate ,then multiplied by the duration of the investment.

The formula for simple interest on an investment is as shown below:

I=PRT

P=principal=$8,000

R=interest rates= 1% and 6%

The value of the greater integer which is the next consecutive odd integer is; -1.

By observation, it follows that the first integer can be represented by 2x+1 while the next consecutive odd integer can be represented as 2x+3.

Hence, it follows that we have;

2(2x+3) - 2x - 1 = 1

4x +6 -2x - 1 = 1

2x = -4

x = -2.

Consequently, the value of the next consecutive greater integer is; 2(-2) + 3= -1.

It consequently follows from the computations above that the value of the greater odd integer is; -1.

Given that the length ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).

According to the statement we know that the radius ratio between two circles. Given that the area of the circle is directly proportional to the square of its radius, then the area ratio is shown below:

A ∝ r²

A = k · r²

A' · r² = A · r'²

A' / A = r'² / r²

A' / A = (r' / r)²

A' / A = [(2 · x) / (5 · y)]²

A' / A = (4 · x²) / (25 · y²)

Answer:

exact: SA = 260π in.²

approximate: SA = 816.81 in.²

Step-by-step explanation:

SA = 2πr² + 2πrh

r = 10 in.

h = 3 in.

SA = 2πr(r + h)

SA = 2π(10 in.)(10 in. + 3 in.)

SA = 260π in.²

SA = 816.81 in.²

A simultaneous equation is a set of equations that has to be solved in relation to each other at the same time. Thus the required number of stamps are:

4¢ stamps = 16

5¢ stamps = 7

A simultaneous equation is a set of equations that has to be solved in relation to each other at the same time. This process is required so as to determine the values of two unknowns e.g x and y.

From the given question, let the number of 4¢ stamps be represented by n, and that of the 9¢ stamp be represented by m.

So that,

n + m = 23 ............ 1

But 100¢ = $1, so that;

4¢ = x

x = [tex]\frac{4}{100}[/tex]

  = $0.04

also,

9¢ = x

x = [tex]\frac{9}{100}[/tex]

  = $0.09

Thus, we have;

0.04n + 0.09m = 1.27 ......... 2

From equation 1, make n the subject of the formula, such that;

n = 23 - m ........... 3

Substitute equation 3 into equation 2

0.04(23 - m) + 0.09m = 1.27

0.92 - 0.04m + 0.09m = 1.27

collect like terms to have;

0.05m = 1.27 - 0.92

          = 0.35

m = [tex]\frac{0.35}{0.05}[/tex]

m = 7

Now substitute the value of m into equation 3

n = 23 - m ........... 3

  = 23 - 7

n = 16

Therefore the number of 4¢ stamps is 16, while that of the 5¢ stamps is 7.
