Which expression uses the commutative property to make it easier to evaluate

Answer:

9(11x+1)

Step-by-step explanation:

99x + 9

The greatest common factor is 9 so put 9 outside of parenthesis

9(11x+9)

Answer:

9(11x+1)

Step-by-step explanation:

We can see that these two values in the equation can be factored by 9 so divide both by 9

99/9= 11

9/9= 1

Rewrite expression by inputting the numbers in parenthesis while keeping the 9 "outside"

9(11x+1)

Answer:

$12,750

Step-by-step explanation:

The price at purchase = 3000 dollars

Sale = 325 percent increase in purchase price.

325% = 3.25

3.25x3000 = 9750 dollars

So, at 325 percent increase in price, this painting sold for $9750.

The retail price of this painting =

Price at purchase + price during sale

= 3000 + 9750

= $12,750

Therefore the retail price is equal to $12,750

The value of the variable 'w' for the given equation 7 ( w + 7 )³ = 7(6³)  is equal to w = -1.

As given in the question,

Given equation is equal to :

7 ( w + 7 )³ = 7(6³)

Divide both the side of the equation by 7 we get,

⇒ 7 ( w + 7 )³ / 7 = 7(6³) /7

⇒( w + 7 )³ = (6³)  

Take cube root both the side of the equation we get,

⇒∛( w + 7 )³ = ∛(6³)  

⇒ w + 7 = 6

Now subtract 7 from both the side of the equation we get,

⇒w + 7 - 7 = 6 - 7

⇒ w = -1

Therefore, the value of the variable 'w' for the given equation is equal to w = -1.

The complete question is:

Solve this equation:

7 ( w + 7 )³ = 7(6³)

Given that 16 families went on a trip and the cost of the trip was Rs. 2,16,352.The amount paid by each family is to be determined by unitary method Hence each family paid Rs.13522

Now, let's solve this by using the method of unitary method. To find the cost of 1 family trip, we will divide the total cost of the trip by the number of families.2,16,352 / 16 = 13,522 So, the cost of the trip per family is Rs. 13,522.Hence, each family paid Rs. 13,522 for the trip.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

⇒ Donuts   2        4        5        8

    Cost     13.80 27.60 34.50 55.20

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The table below shows the ratios of boxed donuts to the cost.

Donuts    A       4        5     C

Cost    13.80  27.60   B   55.20

Now, By definition of ratio, we get;

⇒ A / 13.80 = 4 / 27.60

⇒ A = 13.80 × 4 / 27.60

⇒ A = 2.00

And,

⇒ 4 / 27.60 = 5 / B

⇒ B = 5 × 27.60 / 4

⇒ B = 34.5

⇒ 4 / 27.60 = C / 55.20

⇒ C = 55.20 × 4 / 27.60

⇒ C = 8

Thus, The table with correct values of A, B and C is,

⇒ Donuts   2        4        5        8

    Cost     13.80 27.60 34.50 55.20

To determine Kristina's federal taxes owed for 2022, we need to calculate her taxable income and apply the appropriate tax rate based on the tax brackets for single filers.

From her gross income of $32,500, we need to subtract the deductions that she can claim. Based on the information provided, Kristina can claim either the standard deduction of $12,550 or itemize her deductions, which in her case would be $6,320 + $19,500 = $25,820.

Since the itemized deductions are greater than the standard deduction, we will use the itemized deductions to calculate her taxable income.

Kristina's taxable income would be:

Gross income - Itemized deductions = $32,500 - $25,820 = $6,680

Next, we need to determine which tax bracket Kristina falls into. For tax year 2022, the tax brackets and rates for single filers are:

- 10% on income up to $10,275

- 12% on income between $10,275 and $41,775

- 22% on income between $41,775 and $91,525

- 24% on income between $91,525 and $191,525

- 32% on income between $191,525 and $416,700

- 35% on income between $416,700 and $418,850

- 37% on income over $418,850

Since Kristina's taxable income of $6,680 falls into the 10% tax bracket, her federal tax liability would be:

$6,680 x 0.10 = $668.00

Therefore, Kristina's federal taxes owed for 2022, using the deduction that is best for her, would be $668.00.

Answer:

Step-by-step explanation:

To calculate Kristina's federal taxes owed for 2022, we need to determine her taxable income first. To do this, we need to subtract her deductions from her gross income:

Gross Income = $32,500

Deductions = Mortgage Interest + Medical Expenses

Deductions = $6,320 + $19,500

Deductions = $25,820

Taxable Income = Gross Income - Deductions

Taxable Income = $32,500 - $25,820

Taxable Income = $6,680

Now, we can use the tax brackets and rates for single filers to determine Kristina's federal income tax liability for 2022. Based on the IRS tax tables for 2022, her tax liability would be calculated as follows:

The first $10,275 of taxable income is taxed at 10% = $1,027.50

The amount of taxable income over $10,275 but not over $41,775 is taxed at 12% = $601.20

Total Tax Liability = $1,027.50 + $601.20 = $1,628.70

Therefore, Kristina's federal taxes owed for 2022, using the deduction that is best for her, would be $1,628.70.

Quantity demanded decreases by 8.5 when the price of a burger increases by $1.

Demand curve is a graph which describes the variation of the demand of a goods or a commodity with the variation in the price.

Given demand curve equation is,

Qd = -8.5P + 217

Suppose that the price of a burger increases by $1.

Then the demand equation becomes,

Qd' = -8.5 (P + 1) + 217

      = -8.5P - 8.5 + 217

      = (-8.5P + 217) - 8.5

      = Qd - 1

That is, the quantity demanded decreases by 8.5 when price increases by $1.

Hence the decrease in the quantity demanded is 8.5.

To find the distance between points A and B, we can use trigonometry and the given information.

Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.

Using trigonometry, we can use the tangent function to find the value of "d".

tan(72°) = d / 94.4

To solve for "d", we can rearrange the equation:

d = tan(72°) * 94.4

Using a calculator, we can evaluate the expression:

d ≈ 4.345 * 94.4

d ≈ 408.932

Therefore, the distance between points A and B is approximately 408.932 meters.

The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.

To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.

Expanding the first term, we get 4x^2 + 4x.

Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.

Volume helps describe the amount of space that a shape takes up.

Volume of a Sphere

Volume describes the 3-dimensional size of a shape. Since volume is a 3-D measurement, the units should be cubed; this explains why the answer is given in feet cubed. In order to find the volume, we need to use the radius. The radius of a sphere is the distance from the center to the outside. In this case, we are told that the radius is 9 ft.

Volume Formula

Every regular shape has its own volume formula. For a sphere, the formula is:

So, to find the volume, all we need to do is plug in the radius. For this sphere, r = 9.

When using 3 for pi, the volume of the sphere is 2916 ft³.

So, we know that,

A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.

If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.
