$97 = (Original Price) - (35% of Original Price)

$97 = (Original Price) - (0.35 of Original Price)

$97 = (1 - 0.35) of (Original Price)

$97 = (0.65) of (Original Price)

$97 = 0.65 · (Original Price)

Divide each side by 0.65 .

$97/0.65 = Original Price

$149.23 = Original Price

Answer:

\(\displaystyle y + \frac{1}{2} = 3\, (x - 2)\).

Step-by-step explanation:

Consider a line in a cartesian plane that goes through the point \((x_{0},\, y_{0})\). If the slope of this line is \(m\) (a real constant,) the equation of this line in point-slope form would be:

\(y - y_{0} = m\, (x - x_{0})\).

The line in this question goes through the point \((2,\, (-1/2))\). Thus, \(x_{0} = 2\) whereas \(y = (-1/2)\). The slope of this line is \(m = 3\). Thus, the equation of this line in point-slope form would be:

\(y - (-1/2) = 3\, (x - 2)\).

Simplify to obtain:

\(y + (1/2) = 3\, (x - 2)\).

[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.

A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").

Let's substitute the given truth values for the propositional variables in the given statement:

[~F & (F V F)] ≡ (T ⊃ F)

Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:

[T & F] ≡ (T ⊃ F)

Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:

F ≡ F

Since both sides of the equivalence have the same truth value, the statement is true.

Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

The public increased the amount of currency it held and that banks increased the reserve-deposit ratio is $0.66 million.

Now, According to the question:

December 1921

-Currency held by public: $4.59

-Reserve Deposit ratio: 0.095

-Bank reserves: $3.11

-Money supply: $37.3

December 1932

-Currency held by public: $4.82

-Reserve Deposit ratio: 0.109

-Bank reserves: $3.18

-Money supply: $34.0

We know that:

Bank deposits = (Bank reserves)/(Desired reserve-deposit ratio).

The Fed injected $0.30 billion (the public held $0.23 billion as currency and reserves increased by $0.07 billion was held as reserves). However, the money supply still fell by $3.3 billion.

It would have taken an additional 0.109 × $3.3 billion = $0.36 billion in reserves to support $3.3 in additional deposits.

So the answer is $0.30 billion + $0.36 billion = $0.66 billion.

Answer: x=4 and y=2

Step-by-step explanation: my brain has far surpassed the human comprehension

Answer:

x = -2 , y = -3

Step-by-step explanation:

Let's rearrange the second equation to make x and y on the same side :

y = 1/2x - 2

1/2x - y = 2

Now let's compare the 2 equations :

x + 2y = -8

1/2x - y = 2

Now we multiply the second equation by 2 to make the co-efficient of y the same :

x + 2y = -8

x -2y = 4

Since the signs are different we add the 2 equations :

2x = -4

Divide both sides by 2 to solve for x :

x = -2

Substitute x value into equation 2 to solve for y :

y = 1/2(-2) - 2

y = -1 - 2

y = -3

Our answer is x = -2 , y = -3

Using the perimeter formula, the total length of sparkling lights he can add to the banner is 40.56ft.

The perimeter of a shape is its whole length. It is any border or outline's length that defines a two-dimensional geometric shape. Different figures may have the same perimeter depending on their sizes.

The same wire can be used to create a square if each of its four sides is the same length.

Here in the question,

We have to find the perimeter of the whole figure.

Now the total perimeter =

Sum of sides of the triangle + sum of sides of quadrilateral and the sum of the circumference of the semi-circle.

Perimeter = 10 + 5 + 3 + 10 + πr

= 28 + 3.14 × 8/2

= 28 + 12.56

= 40.56ft.

Step-by-step explanation:

We will denote the almirahs as A1 and A2 for ease of explanation. I am omitting currency until the final answer

For the following computations note that x% = x/100 in decimal so
15% = 15/100 = 0.15
13 1/3% = 13 1/3 ÷ 100 = 40/3 ÷ 100 = 40/300

Cost of A1 = 4800

A1 was sold for a loss of 15%

Loss = 15% of 3640 = 0.15 x 3640  = Rs 546

A2 bought at 4800 was sold at a gain of 13 1/3%

Gain from sale = 13 1/3% of 4800 = 40/300 x 4800 =Rs 640

We have to treat gain as positive and loss as negative to arrive at the answer

Net gain/loss = 640  - 546 = Rs. 94

It is very easy to find the perimeter of a square when its area is given in the question. For that, you only ned to know one fomula. That formula is: Area = side^2

For this particular question, the given value for the area of the square is 36 sq.cm. So, we can solve for the side(s) by substituting the given value in the above mentioned formula.

We get

36 = s^2

Now, we need to get the square root of both sides, which gives us

s = √36 s = 6 cm

Since all the sides of a square are equal in length, the side length is 6 cm. Now to determine the perimeter, we must multiply the side length by 4 (because there are 4 equal sides in a square). That gives us Perimeter = 4 x side length Perimeter = 4 x 6 cm.

Therefore, the perimeter of the square is 24 cm.

Answer:

B

Step-by-step explanation:

Given

x² + 14x = 51

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(7)x + 49 = 51 + 49 , that is

(x + 7)² = 100 ( take the square root of both sides )

x + 7 = ± \(\sqrt{100}\) = ± 10 ( subtract 7 from both sides )

x = - 7 ± 10

Thus

x = - 7 - 10 = - 17

x = - 7 + 10 = 3

The mean absolute deviation is 0.75

To calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set

From the information given, we have that the data set is;

8 9 9 7 8 6 9 8

Let's calculate the mean, we get;

Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8

Mean = 64 / 8

Divide the values

Mean = 8

Let's determine the absolute difference, we get;

Absolute differences=

|8 - 8| = 0

|9 - 8| = 1

|9 - 8| = 1

|7 - 8| = 1

|8 - 8| = 0

|6 - 8| = 2

|9 - 8| = 1

|8 - 8| = 0

Find the mean of the absolute differences:

Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8

Absolute difference = 6 / 8 = 0.75

The polynomial which in the descending order of the polynomial 4x³ + 3x⁷ - 9x + x¹² is option A.  x¹² + 3x⁷ + 4x³ - 9x.

Polynomial is an algebraic expression that consists of variables, coefficients, constants and powers or exponents which are all combined using operations like subtraction, addition, multiplication.

We have the polynomial,

4x³ + 3x⁷ - 9x + x¹²

We have to write it in the descending order.

Descending order is to write it in a way that the power of the variable decreases for each succeeding term.

Here the term x¹² has the highest power of 12. So it should be the first term.

Then the highest power is 7 for the term 3x⁷ and then comes 4x³ and -9x.

Hence the polynomial in the descending order is x¹² + 3x⁷ + 4x³ - 9x.
