Microeconomics is the study of psychology of individuals at small scale.

In microeconomics, price of goods helps to determine the quantity supplied and the quantity demanded.

Quantity demanded is determined by

1. Desire of any good 2. Willingness to buy that good 3.Ability to buy a good

Other than that quantity supplied is determined by

1.Production cost [supply can increase with decrease in cost of production]

2. Productivity [supply can increase with increase in number of workers or hard working workers]

3.Technology[supply can increase with increase in the use of new technology related to production]

4.Govt regulation [it can either restrict or advertise the goods that can either increase or decrease the supply of that good respectively.]

5.Taxes and subsidies [implication of taxes can decrease the supply but by implication of subsidies supply can increase]etc.

So, Ist option is correct that the quantity supplied is determined by production cost and quantity demanded is determined by desire for the product.

Answer:

m∠x = 63°

m∠y =45°

m∠z = 72°

I hope this helps! :)

Answer:

Step-by-step explanation:

It is given that ABCD is a parallelogram, thus by using the properties of parallelogram, we have

∠A=∠C (Opposite angles of parallelogram are equal)

⇒∠x=63°

Thus, the measure of angle A that is x is 63°.

Now, ∠ABC+∠BCD=180°(Corresponding angles of parallelogram)

⇒∠ABD+∠DBC+63=180

⇒∠DBC=180-135

⇒∠DBC=45°

Thus, y=∠DBC=45° (Alternate angles)

and z=∠DBA=72° (Alternate angles)

Hence, the measure of angle x, y and z are 63°, 45° and 72° respectively.

Answer:

His method is incorrect. By finding 1/2 the width and 1/2 the length, if we multiply them , we would get 1/4 of the original area.

Area = 0.5*l*0.5*w = 0.25*l*w = l*w/4

Let us establish

length = l

width = w

Original Area = l*w

Half the area = (a*l)*(b*w) = 0.5*(l*w)

This means that

a*b = 0.5

if b is equal to a, then

a = √0.5  = √2/2 = 0.707

Then,  if a factor of a, where to be introduced in the lenght and width of the tile, we would  obtain  half the area.

Answer:

Percentage of amount paid for labor, parking space and busing are 12%, 39% and 49% respectively.

Step-by-step explanation:

The stadium pays the amount for labor = $14000

Amount paid for leasing a parking space = $45000

and to provide busing to and from the parking space = $57000

Total amount paid = $14000 + $45000 + $57000

                              = $116000

Percentage of amount paid for labor = [tex]\frac{\text{Amount paid for labor}}{\text{Total amount paid}}\times 100[/tex]

= [tex]\frac{14000}{116000}\times 100[/tex]

=12.06

≈ 12%

Percentage of amount paid for parking space

= [tex]\frac{\text{Amount paid for parking space}}{\text{Total amount paid}}\times 100[/tex]

= [tex]\frac{45000}{116000}\times 100[/tex]

= 38.79%

≈ 39%

Percentage of amount paid for busing = [tex]\frac{\text{Amount paid for busing}}{\text{Total amount paid}}\times 100[/tex]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

If two figures are similar. then the ratio of its areas is equal to the scale factor squared

In this problem we have a tile with a length of 1 foot by a width of 1 foot

The area of the tile is equal to

[tex]A=LW[/tex]

substitute the values

[tex]A=(1)(1)=1\ ft^{2}[/tex]

Let

z-------> the scale factor

x------> the area of 1/2 tile

y------> the area of the original tile

so

[tex]z^{2} =\frac{x}{y}[/tex]

substitute

[tex]z^{2} =\frac{(1/2)}{1}[/tex]

[tex]z=\frac{\sqrt{2}}{2}[/tex] -----> scale factor

therefore

To find the area of 1/2 tile must multiply the dimensions of the tile by the scale factor

so

[tex]L=1*\frac{\sqrt{2}}{2}=\frac{\sqrt{2}}{2}\ in[/tex]

[tex]W=1*\frac{\sqrt{2}}{2}=\frac{\sqrt{2}}{2}\ in[/tex]

Calculate the area

[tex]A=\frac{\sqrt{2}}{2}*\frac{\sqrt{2}}{2}=\frac{1}{2}\ ft^{2}[/tex]

Martin's method is incorrect because to find the area of 1/2 tile, he multiplies the dimensions by 1/2

so

[tex]L=1*\frac{1}{2}=\frac{1}{2}\ in[/tex]

[tex]W=1*\frac{1}{2}=\frac{1}{2}\ in[/tex]

the area will be

[tex]A=\frac{1}{2}*\frac{1}{2}=\frac{1}{4}\ ft^{2}[/tex]

The rectangle's length is 12 cm, and the width is 9 cm, calculated by setting up a system of equations using the given perimeter and the relationship between length and width.

To find the length and width of the rectangle when given its perimeter and a relationship between its length and width, we can set up a system of equations. First, let's denote the length of the rectangle as L and the width as W. According to the question, the width is 3 centimeters more than half the length, so we have W = ½L + 3.

Since the perimeter (P) of a rectangle is given by P = 2L + 2W, and we know the perimeter is 42 centimeters, we can set up an equation: 42 = 2L + 2(½L + 3). Simplifying this, we get 42 = 2L + L + 6 or 42 = 3L + 6. Subtracting 6 from both sides gives us 36 = 3L or L = 12 centimeters for the length.

Now we can find the width using the previous relationship W = ½L + 3. Substituting the value of L, we get W = ½(12) + 3 = 6 + 3 = 9 centimeters for the width.

Therefore, the length is 12 centimeters and the width is 9 centimeters.

Explanation:

To find the missing dimension of a triangle, given the height and area, we can use the formula for the area of a triangle A = (b × h) / 2, where A is the area, b is the base, and h is the height. Given that the height h is 7 inches and the area A is 21 square inches, we can rearrange the formula to solve for the base b:
Area = (base × height) / 2 → 21 = (b × 7) / 2 → b = (21 × 2) / 7 → b = 6

The missing dimension, the base of the triangle, is 6 inches, provided height of 7 inches and area of 21 square inches.

Answer:

40

Step-by-step explanation:

Given that Anita divides 1438 by a multiple of 10

i.e. she might have divided by 10 or 20 or 30 .....

The tenth column is 3

So quotient value would be

30+d for some d in the unit column

It may be 31 or 32.....

Say it is 31, then 1438/31 =46.38 and

1438/39 = 36.87

i.e she must have divided by 40 only

Verify:

1438/40 =35 as quotient and 38 as remainder.

So she divided by 40

To determine how often ATM withdrawals must be made for the local savings account to be a better deal than the online savings account, we compare the interest earned and ATM fees. By solving the inequality, it is found that more than $14.06 ATM withdrawals must be made in a year.

To determine how often you must make ATM withdrawals for the local savings account to be a better deal than the online savings account, we need to compare the interest earned from each account and the fees associated with ATM withdrawals. Let's assume the time period is one year.

For the local savings account, you earn interest of 1.75% annually. So, if you deposit $3,750, you will earn ($3,750 * 1.75%) = $65.63 in interest.

For the online savings account, you earn interest of 3.25% annually. However, each ATM withdrawal incurs a fee of $4. Let's assume you make 'x' withdrawals in a year. So, the total interest earned would be ($3,750 * 3.25%) - ($4 * x).

We need to find the point where the interest earned from the online savings account is less than the interest earned from the local savings account. This can be calculated as:

($3,750 * 3.25%) - ($4 * x) < $65.63

Simplifying this inequality, we get:

0.0325 * $3,750 - $4 * x < $65.63

Adding $4 * x to both sides, we have:

0.0325 * $3,750 < $65.63 + $4 * x

Simplifying further, we get:

$121.87 < $65.63 + $4 * x

Subtracting $65.63 from both sides, we have:

$121.87 - $65.63 < $4 * x

Simplifying again, we get:

$56.24 < $4 * x

Dividing both sides by $4, we find:

$14.06 < x

So, you must make more than $14.06 ATM withdrawals in a year for the local savings account to be a better deal than the online savings account.
