chores around the house. What is the minimum number of weeks it will take her to have enough money to
buy the shoes?

Answer:

41,500 people

Step-by-step explanation:

First you find 3% of 36,000= 1,080

Then you do 1080 x 5= 4,500

Then finally do 36,000 + 4,500= 41,500

Answer:

Your answer would equal the same on the other side.

-26-4m=-4m-26

if you minus 26 from both sides youll have -4m on both sides also. So it would equal. So you have an Equaled equation if that makes sense.

Consumer surplus $5 as we solve the Q by given data

Consumer surplus is the difference between the consumer's willingness to pay and the price of the commodity.

Consumer surplus in economics, also called social surplus or consumer surplus, is the difference between the price a consumer pays for a commodity and the price the consumer is willing to pay in exchange for giving it up.

Producer surplus is the difference between the price of a commodity and the lowest price at which a seller is willing to sell it.

Consumer Surplus = Willingness to Pay - Price of the Good.

Item Price = $35 - $10 = $25

$30 - $25 = $5

Producer surplus is the difference between the price of a commodity and the lowest price at which a seller is willing to sell it.

Evaluating the function for x=2, F(x)= 8.

What is a linear equation?

Alternatively, a linear equation can be obtained by equating the linear polynomial over the field from which the coefficients are taken to zero.

The solution of such an equation is the value that makes the equation true when the unknowns are substituted.

If there is only one variable, there is only one solution. Often the term linear equation alludes to this special case where the variables are appropriately called unknowns.

With two variables, each solution can be interpreted as the Cartesian coordinates of a point on the Euclidean plane. The solutions of linear equations form lines in the Euclidean plane. Conversely, each line can be viewed as the set of all solutions to linear equations in two variables. This is the origin of the term linear for these types of equations. More generally, the solution of a linear equation in n variables forms a hyperplane (a subspace of dimension n − 1) in the Euclidean space of dimension n.

Therefore, Evaluating the function for x=2, F(x)= 8.

The function f(x) = 1/x^2 is defined for all x except x = 0. To find the nth degree Taylor approximation of f(1.02) about x = 1, we need to calculate the nth derivative of f(x) and evaluate it at x = 1.

The function f(x) = 1/x^2 can be written as f(x) = x^(-2). Taking the derivatives of f(x), we have:

f'(x) = -2x^(-3)

f''(x) = 6x^(-4)

f'''(x) = -24x^(-5)

...

The nth derivative of f(x) can be written as f^n(x) = (-1)^(n+1) * (2n)! * x^(-(n+2)). To find the nth degree Taylor approximation, we evaluate the nth derivative at x = 1 and multiply it by (x - 1)^n/n!. The nth degree Taylor approximation Tn of f(1.02) about x = 1 is given by:

Tn = f(1) + f'(1)(x - 1) + f''(1)(x - 1)^2/2! + f'''(1)(x - 1)^3/3! + ... + f^n(1)(x - 1)^n/n!

Substituting the derivatives at x = 1, we have: Tn = 1 + (-2)(1.02 - 1) + 6(1.02 - 1)^2/2! + (-24)(1.02 - 1)^3/3! + ... + (-1)^(n+1) * (2n)! * (1.02 - 1)^n/n!. This expression represents the nth degree Taylor approximation of f(1.02) about x = 1.

Pyramid B has a volume that is 8 times the volume of Pyramid A.

The volume of a pyramid is calculated as one third of the multiplication of the base area and the height, as follows:

V = 1/3 x Ab x h.

For a square base of side length s, we have that Ab = s², hence:

V = s²h/3.

Then the volume of Pyramid A is given as follows:

V = 12² x 8/3

V = 384 cubic inches.

The volume of Pyramid B is given as follows:

V = 24² x 16/3

V = 3072 cubic inches.

Thee flow rate is 0.486 m³/s and the head at the operating point is 8.85 m.

Reservoir B to reservoir A with the help of a pump at C.Diameter = 0.5 M Length = 1 km

Friction coefficient, f, can be taken as 0.02Hpump = 20 - 20Q².

Total head loss, Hl = (f L (V²))/ 2gd

= [(0.02 × 1000 × (V²))/ (2 × 9.81 × 500)]

= 0.204V²

According to the Bernoulli equation, the total head at point A and point C must be the same.

(p/ρg) + z + V²/2g = constant(z is elevation)

Pumping head = head loss + head at point A + friction lossHead loss (Hl) = (f L (V²))/ 2gd

According to the given data; we need to calculate the flow rate and the head at the operating point.

The formula to calculate the head loss is:

Hl = [(f L (V²))/ (2gd)]

Flow rate (Q) = [(2 ΔH) / (√(g × π² × d⁵ × Δp))]

Hpump = 20 - 20Q²

Head loss (Hl) = [(f L (V²))/ (2gd)]

Pumping head = head loss + head at point A + friction Loss

Let Q be the flow rate and H be the head at the operating point.So, pumping head = Head loss + Head at point A + Friction loss.

H = Hpump + Ha + Hl

Here, ΔH = H

= Head at point A - Head at point

B = 25 m

= 25000 mm

∆p = Head loss + Pumping head

(Hl + Hpump) = (20 - 20Q²) + 25000 + [(0.02 × 1000 × (V²))/ (2 × 9.81 × 500)]

Also, we know that, Q = A × V

Where,A = (π/4) × d²A

= (π/4) × (0.5)²

= 0.196 m²

So, Q = 0.196 V

We can replace the value of V in equation (1) and get the value of Q.∆p = 25020 + 0.204V² - 20Q² ----------- (1)

Hpump= 20-20Q²

= 20 - 20(Q/2) × (Q/2)

Hpump = 20 - 5Q²

Therefore, Δp = 25020 + 0.204V² - 5Q²

Substitute V = Q / 0.196 in Δp equation.

Δp = 25020 + 0.204 (Q/0.196)² - 5Q²

On differentiating this equation,

we get;0 = 0.204 × (1/0.196) × (Q/0.196) - 10QdΔp / dQ

= 0.204 / 0.196 Q - 10Q

= 1.041Q - 10Q

At equilibrium, dΔp / dQ = 0.

So, 1.041Q - 10Q = 0

=> Q = 0.486 m³/s

The head at the operating point,H = 20 - 20Q²

= 20 - 20 (0.486 / 2) × (0.486 / 2)

= 8.85 m (approx)

Hence, the flow rate is 0.486 m³/s and the head at the operating point is 8.85 m.

i think this is correct ans if this is correct ans pls give me brainliest.

So, option (a) is the correct answer.

(a) Triangle with lengths of sides 7 cm, 8 cm and 9cm is a right triangle. This is because the Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, 9^2 = 7^2 + 8^2, which is true, hence the triangle has a right angle.

(b) ABC with AB = 8.7 cm, AC = 7 cm and BC = 6cm can't be determined as it depends on the angles, as the sides are given but the angles are not.

(c) PQR such that PQ = QR = PR = 5cm is an equilateral triangle. This is because in an equilateral triangle all three sides are of equal length.

(d) DEF with D = 90 degrees can't be determined as only the angle is given, we need the length of the sides as well

(e) XYZ with Y = 90 and XY = YZ can't be determined as the angle and the sides are not enough information

(f) LMN with L = 30, M = 70 and N = 80 is not a triangle as the sum of two sides is less than the other side, hence the triangle inequality theorem is violated.

Therefore, Option (a) is the correct answer.

It's worth noting that a triangle can be defined by its three sides as well as by its three angles, but in any case, we need enough information to determine the type of triangle.

Answer:

  88 : 132 : 44

Step-by-step explanation:

You want 264 divided into parts in the ratio 2 : 3 : 1.

The ratio units add up to 2+3+1 = 6. So, the part represented by 1 ratio units is 264/6 = 44. The 2 ratio units represent 88, and 3 represent 132.

The division is ...

  2 : 3 : 1 = 88 : 132 : 44

<95141404393>

The Values corresponding to the ratio 2:3:1 for a total value of 264 are 88, 132, and 44, respectively.

To divide 264 in a ratio of 2:3:1, we need to find the respective parts that correspond to each ratio.

Let's break down the total value of 264 into three parts based on the given ratio of 2:3:1.

Step 1: Find the total number of parts in the ratio

The total number of parts in the ratio 2:3:1 is 2 + 3 + 1 = 6.

Step 2: Calculate the value of each part

To find the value of each part, we divide the total value (264) by the total number of parts (6):

Value of each part = Total value / Total number of parts

                  = 264 / 6

                  = 44

Step 3: Determine the value for each ratio component

Now, we can calculate the value for each component of the ratio:

- For the ratio component 2, the value is 2 parts * 44 = 88.

- For the ratio component 3, the value is 3 parts * 44 = 132.

- For the ratio component 1, the value is 1 part * 44 = 44.

Therefore, the values corresponding to the ratio 2:3:1 for a total value of 264 are 88, 132, and 44, respectively.

In summary, when dividing 264 in a ratio of 2:3:1, the values corresponding to each ratio component are 88, 132, and 44, respectively.

The optimal solution for the amount of cash to withdraw each time to minimize transportation costs and maximize interest earnings is determined by calculating the Economic Order Quantity (EOQ) using the formula Q = √((2 * C * T) / r), and rounding the result to a convenient amount.

The Economic Order Quantity (EOQ) model is typically used for inventory management, not for optimizing cash withdrawals. However, if we assume that the question is seeking an optimal withdrawal strategy to minimize transportation costs and maximize interest earnings, we can approach it as follows:

Let's denote:

C = Annual cash need ($5,000)

T = Transportation cost per visit ($5)

r = Annual interest rate (5%)

To find the optimal solution for the amount of cash to withdraw each time, we can consider the trade-off between transportation costs and interest earnings. The objective is to minimize the total cost.

Calculate the optimal order quantity (Q) using the EOQ formula:

Q = √((2 * C * T) / r)

Round the calculated Q to the nearest convenient amount, such as multiples of $100 or $500.

The optimal solution would be to withdraw the rounded Q amount each time to minimize transportation costs while still meeting the annual cash need.
