The total cashback you will get back is\($ 49.75}\)

The Given, original price \($=\$ 50$\) Sales fax\($=9.5 \%$\\\)

For first sale

A sale is a transaction between two or more parties that involves the exchange of tangible or intangible goods, services, or assets for money. In some cases, assets other than cash are paid to a seller.

In the financial markets, a sale can also refer to an agreement that a buyer and seller make regarding a financial security, its price, and specific arrangements for its delivery.

Regardless of the context, a sale is essentially a contract between a seller of a particular good or service and a buyer who is willing to pay for that good or service.

for second Sale:-

There is no tax

So price\($=\$ 50$\)

For third sale: - Buy 3 and get 1 half of

The correct answer is A. The statement is always true. If f(x) is a polynomial, then as x approaches 0, the right-hand limit exists and is equal to the left-hand limit.

For a polynomial function f(x), as x approaches a specific value c, the limit of f(x) as x approaches c is equal to f(c). This property holds true for any value of c within the domain of the polynomial.

In the given question, we are considering the case where c is equal to 0. So, the limit of f(x) as x approaches 0 is equal to f(0). Since f is a polynomial, it can be written as f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀, where a₀, a₁, ..., aₙ are coefficients.

When x approaches 0, all the terms in the polynomial, except for a₀, become 0. Therefore, the limit of f(x) as x approaches 0 is equal to f(0) = a₀.

Hence, the right-hand limit (as x approaches 0⁺) and the left-hand limit (as x approaches 0⁻) both exist and are equal to f(0) = a₀. Therefore, the statement is true for polynomial functions.

The measure of length of y of the triangle is y = 46.44486 units

Given data ,

Let the first triangle be represented as ΔABC

Now , let the second triangle be ΔABD

And , y = a + b

where from the trigonometric relations , we get

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

So , sin 30° = AB / 34

AB = 17 units

Now , from the trigonometric relation , we get

tan 45° = AB / b

b = AB / 1

b = AB

And , cos 30° = a / 34

a = 29.44486

So , y = 29.44486 + 17

Answer: We can start by using the information given to find the total bill amount.

If the water/sewer/garbage portion of the bill is 72% of the total bill, then the remaining 28% of the bill must be for other utilities. We can use a proportion to set up the equation:

72/100 = 94.41/x

where x is the total bill amount.

We can cross-multiply and solve for x:

72x = 100 * 94.41

x = (100 * 94.41) / 72

x = 123.84

To the nearest cent, the total amount of the utility bill was $123.84.

Step-by-step explanation:

To find the sum of the digits of all possible values of 'a', we need to add the sum of the digits of each value of abc. The sum of the digits for all possible values of a would be 8 + 7 + 15 + ... + 27, which can be calculated further.

The divisibility rule for 125 states that a number is divisible by 125 if the last three digits are divisible by 125. In the case of 24687abc, we know that the last three digits (abc) must be divisible by 125. This means that abc must be a multiple of 125. The smallest multiple of 125 is 125, and the largest is 999, so the possible values of abc are 125, 250, 375, 500, ..., 999.

The sum of the digits of each possible value of a can be calculated by adding the individual digits of each value of abc. For example, for the value 125, the sum of the digits is 1 + 2 + 5 = 8. For the value 250, the sum of the digits is 2 + 5 + 0 = 7. For the value 375, the sum of the digits is 3 + 7 + 5 = 15.

452.389342 cubic inches

Step-by-step explanation:

The volume of a sphere is calculated using the formula V = 4/3 pi r^3

to determine the radius, you can notice that 4 spheres take up 24 in in length. This means that the radius of 1 sphere is 24/4/2 = 3 inches.

from there we plug and play: V = 4/3 * pi * 3^3 = 113.097336 cubic inches.

Note that this is only the volume of 1 sphere, so we multiply by 4

and we get 452.389342 cubic inches

Answer:

Step-by-step explanation:

Radius of each sphere: 24/4/2=3

g(-3) = -13

Step-by-step explanation:

Plug in -3 for n in the equation:

g(n) = 3n - 4

g(-3) = 3(-3) - 4

Remember to follow PEMDAS. First, multiply, then subtract:

g(-3) = 3 * -3 = -9

g(-3) = -9 - 4

g(-3) = -13

-13 is your answer for g(-3).

G(-3) means to replace n with -3:

3n -4 = 3(-3) -4 = -9-4 = -13

The answer is -13

Answer:

C. 14%

Step-by-step explanation:

We know that Dallas's wage increased from $9 to $10.25.

Let's say the percent increase is x. Then we write the expression:

9 + x * 9 = 10.25

Divide by 9 from both sides:

1 + x = 10.25 / 9 ≈ 1.14

Subtract 1 from both sides:

x = 1.14 - 1 = 0.14

Since x is a percent, that means x = k/100, where k is an integer. So we have:

x = k/100 = 0.14

Multiply both sides by 100:

k = 0.14 * 100 = 14%

The answer is thus C.

We can write the given algebraic expression as a function of \(\theta\) as: \(f(\theta) = 9|\tan\theta|\)

We are given the algebraic expression:

\(\sqrt{x^2 - 81}\)

We are also given the substitution:

\(x = 9\sec\theta\)

We can substitute x  with \(9\sec\theta\) in the given expression:

\(\sqrt{x^2 - 81} = \sqrt{(9\sec\theta)^2 - 81}\)

Simplifying the expression inside the square root:

\(\sqrt{(9\sec\theta)^2 - 81} = \sqrt{81\sec^2\theta - 81} = \sqrt{81(\sec^2\theta - 1)}\)

Recall that \(\sec^2\theta - 1 = \tan^2\theta .\)

Substituting this into the expression:

\(\sqrt{81(\sec^2\theta - 1)} = \sqrt{81\tan^2\theta} = 9|\tan\theta|\)

Finally, we can write the given algebraic expression as a function of \(\theta\) as:

\(f(\theta) = 9|\tan\theta|\)

Note that the absolute value is used because the substitution \(x = 9\sec\theta\)  only holds for \(0 < \theta < \frac{\pi}{2}\), but \(\tan\theta\) can be negative in the second quadrant. The absolute value ensures that the function is always non-negative.

The value of P(B) when A and B are mutually exclusive is 0.4 and when A and B are independent is zero.

Mutually exclusive events are those events which do not occur at the same time. For a mutually exclusive event we have the formula,

P(A∪B) = P(A) + P(B) - P(A∩B)

Here P(A∩B) is equal to zero and P(A) = 0.3 and P(A∪B) = 0.7

Now when we substitute the values we get

0.7 = 0.3 + P(B)

=> P(B) = 0.7 - 0.3

=> P(B) = 0.4

Now, if the events are independent then we have the formula

P(A∩B) = P(A)×P(B)

Since we already know that P(A∩B) = 0 then

0 = 0.3×P(B)

=> P(B) = 0 which means that the event will not take place.

25 + 144 = Hypotenuse²

169 = Hypotenuse²

So,

Hypotenuse = root169 = 13

Perimeter of Right triangle = sum of all sides

Perimeter of Right triangle = 5 + 12 + 13

Perimeter Of Right triangle = 5 + 12 + 13 = 30

Option D. 30 units is the correct answer

Answer:

30

See the attached worksheet.  The perimeter of the triangle is the sum of its three sides, labelled a, b, and c.

a and b can be calculated from the graph, as shown on the worksheet.

Once a and b are know, use the ZPythagorean Theorem to find c, which is 13.

Finially, add the sides a, b, and c:  5 + 12 + 13 = 30, the perimeter.

∠ABD and ∠EBC are complementary by the definition of complementary angles.

Given that in a figure, BD ⊥ BC ; ∠ABD ≅ ∠DBE.

We need to prove ∠ABD and ∠EBC are complementary.

BD ⊥ BC = given

∠DBC = 90° by the definition of perpendiculars.

∠ABD ≅ ∠DBE = given

∴ ∠ABD = ∠DBE by the definition of congruence.

Using the angles addition postulate,

∠EBC + ∠DBE = 90°

Now, replace ∠DBE by ∠ABD, we get,

∠EBC + ∠ABD = 90°

Hence ∠ABD and ∠EBC are complementary by the definition of complementary angles.

The length for which 98% of the nails will be longer is approximately 6.466 cm.

Step-by-step explanation:

First, we need to convert the units of the standard deviation to centimeters, since the mean is also given in centimeters. 2 mm is equal to 0.2 cm.

Next, we need to find the z-score that corresponds to the 98th percentile. We can use a standard normal distribution table or calculator to find this value. The z-score corresponding to the 98th percentile is approximately 2.33.

Finally, we can use the formula for a z-score to find the length of nail corresponding to this z-score:

Solving for x, we get:

Therefore, the length for which 98% of the nails will be longer is approximately 6.466 cm.
