The distance travelled by Jasmine in 3 1/5 hours is 108 miles.

Speed is simply referred to as distance traveled per unit time.

Mathematically, Speed = Distance ÷ time.

Given the data in the question;

Plug in given values into the above equation and solve for distance.

Speed = Distance / time

Distance = Speed × Time

Distance = 33 3/4 × 3 1/5

Convert to improper fraction

Distance = (33 × 4 + 3)/4 × ( 3 × 5 + 1)/5

Distance = 135/4 × 16/5

Distance = 2160 / 20

Distance = 108 miles

Therefore, the distance covered is 108 miles.

Answer:

25.3"

Step-by-step explanation:

use Pythagorean Theorem:

15.5² + 20² = c²

240.25 + 400 = c²

640.25 = c²

c = \(\sqrt{640.25}\) ≈ 25.3

the sum of all the angles = 180

13x-11 + 8x-9 + 30x-4 =180

51x-24 = 180

51x = 204

x=4

w= 8x-9= 8×4-9

= 2e°

Answer:

23°

Step-by-step explanation:

First, note that the sum of angles in a triangle is 180°.

So, m∠W + m∠B + m∠T = 180°

Substitute the measures.

(8x - 9) + (13x - 11) + (30x - 4) = 180

Simplify.

8x + 13x + 30x - 9 - 11 - 4 = 180

51x - 24 = 180

Add 24 to both sides.

51x = 204

Divide both sides by 51.

x = 4

Then, substitute x = 4 into m∠W

8x - 9 = 8 * 4 - 9 = 32 - 9 = 23°

So, m∠W = 23°

Answer:

The budgeted cost of goods sold in June is $ 10,500,000

Step-by-step explanation:

In order to determine the budgeted cost of goods sold,we need to first and foremost establish goods sold in quantity terms as follows:

goods sold=opening stock+goods produced-closing stock

goods produced=sales-opening stock+closing stock

goods produced=350,000-84,000+130,000=396,000

goods sold=84,000+396,000 -130,000=350000

The cost of producing one unit is $30

costs of goods sold=goods sold*production cost per unit=$30*350000 =

$ 10,500,000.00  

Alternatively:

sales units *unit cost of production=$30*350,000=$ 10,500,000.00

Answer:

In TTM/Imagine Math it is top left or a.

Step-by-step explanation:

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

Answer:

Step-by-step explanation:

The length of the diagonal cut that Julie made on the rectangular piece of fabric is approximately 9.85 inches.

To find the length of the diagonal cut that Julie made on the rectangular piece of fabric, we can use the Pythagorean theorem.

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 other two sides.

In this case, the length and width of the fabric form the two sides of a right triangle, with the diagonal cut being the hypotenuse.

Given that the fabric is 9 inches long and 4 inches wide, we can label the length as the base (b) and the width as the height (h) of the right triangle.

Using the Pythagorean theorem, we have:

hypotenuse^2 = base^2 + height^2

Let's substitute the values into the equation:

hypotenuse^2 \(= 9^2 + 4^2\)

hypotenuse^2 = 81 + 16

hypotenuse^2 = 97

To find the length of the hypotenuse (diagonal cut), we need to take the square root of both sides:

hypotenuse = √97

Calculating the square root of 97 gives approximately 9.85.

Therefore, the length of the diagonal cut that Julie made on the rectangular piece of fabric is approximately 9.85 inches.

Answer:

The correct option is;

x³ + 4·x² + 3·x  < x³ + 13·x² + 54·x + 72.

Step-by-step explanation:

The given parameters are;

The basic plan of the decorator = x wall-color options, x + 1 ceiling-colr options, and x + 3 floor options

The gold plan of the decorator = All of the basic plan options plus 3 additional options in each category

Therefore, the gold plan of the decorator = (x + 3) wall-color options, (x + 1 + 3) ceiling-color options, and (x + 3 + 3) floor options

The total number unique layouts offered by the basic plan = x × (x + 1) × (x + 3) = x³ + 4·x² + 3·x

Also, the total number unique layouts offered by the gold plan = (x + 3) × (x + 1 + 3) × (x + 3 + 3) = (x + 3) × (x + 4) × (x + 6)  = x³ + 13·x² + 54·x + 72

The rate at which Ben cycles, if Andy cycles at 12 kmph is 48 kmph.

The formula for finding the rate at which Ben cycles, if Andy cycles at 12 kmph, is given by:

Ben's rate = Andy's rate x Time taken by Ben ÷ Time taken by Andy

Therefore, Ben's rate = 12 kmph x (52/3) hours ÷ (13/3) hours

Ben's rate = 48 kmph

To calculate Ben's rate, we first need to calculate the time taken by each of them. Andy sets out to cycle from Delhi to Rohtak, and Ben starts from Rohtak to cycle to Delhi. After passing each other, they completed their journey in (13/3) hours and (52/3) hours respectively.

We can calculate the rate at which Ben cycles as follows:

Calculate the time taken by each of them.

Time taken by Andy = 13/3 hours

Time taken by Ben = 52/3 hours

Calculate Ben's rate using the formula given above.

Ben's rate = 12 kmph x (52/3) hours ÷ (13/3) hours
