To find the number of containers that Jackson can fill, we need to divide the total amount of salt he has by the amount of salt that each container can hold. We can convert the mixed number of 4 1/2 pounds to an improper fraction:

4 1/2 = 9/2

Next, we can express the amount of salt each container can hold in terms of improper fractions:

2/5 a pounds = 10/25 a pounds = 2/5 a pounds

Now we can set up the division:

(9/2) ÷ (2/5)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

(9/2) × (5/2)

Simplifying the fractions, we get:

(9 × 5) / (2 × 2) = 45/4

Therefore, Jackson can fill 45/4 containers with the 4 1/2 pounds of salt. We can convert this improper fraction to a mixed number:

45/4 = 11 1/4

So Jackson can fill 11 1/4 containers with the salt he has. However, since we are dealing with a physical quantity, we need to round down to the nearest whole number of containers, which is 11. Therefore, Jackson can fill 11 containers with salt.

Answer:

The selling price of the bag is $22.5

Step-by-step explanation:

Buying Price = $25,

Selling Price = ?

Since they sold it at a loss of 10%,

So, they sold it for a price 10% less than the buying price,

or at 90% or 0.9 of the buying price,

so,

Selling Price = (0.9)(25) = $22.5

The measure of ∠x is 72 degrees.

If two angles are supplementary, it means that their measures add up to 180 degrees. Let's denote the measure of ∠x as x degrees. Supplementary angles are a pair of angles that, when combined, add up to 180 degrees. In other words, if you have two angles that are supplementary, the sum of their measures will always be 180 degrees.

Given that ∠y measures 108 degrees, we can set up the equation:

∠x + ∠y = 180

Substituting the known value for ∠y, we have:

x + 108 = 180

To find the measure of ∠x, we need to isolate x on one side of the equation. Subtracting 108 from both sides, we get:

x = 180 - 108

x = 72

Therefore, the measure of ∠x is 72 degrees.

To use the tangent ratio in a triangle, you need to know the lengths of two sides or the measures of two angles in the triangle. The tangent ratio relates the length of the side opposite an angle to the length of the side adjacent to that angle in a right triangle.

The tangent ratio is a trigonometric ratio that relates the length of one side of a right triangle to the length of another side. It is defined as the ratio of the length of the side opposite a given angle to the length of the side adjacent to that angle.

In order to use the tangent ratio, you must have knowledge of the triangle's sides or angles. If you know the lengths of two sides of a right triangle, you can use the tangent ratio to find the measure of one of the acute angles in the triangle. Conversely, if you know the measure of one of the acute angles, you can use the tangent ratio to find the ratio of the lengths of the sides in the triangle.

Essentially, to apply the tangent ratio, you need to have sufficient information about the triangle to identify the sides or angles involved in the ratio calculation. This information can be provided in terms of lengths of sides or measures of angles, allowing you to use the tangent ratio to solve for missing values or determine specific relationships within the triangle.

1. The slope of each object are: a) 0.6. b) 1.375.

2. The slope of the road section is 0.02.

3. No, a wheelchair ramp with a vertical rise of 1.4 m along a horizontal run of 8 m does not satisfy the regulation.

4. The slope of each line segment are: a) 0.6. b) -0.6.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

By substituting the given data points into the formula for the slope of a line, we have the following;

Part 1

Slope of a = 3/5

Slope of a = 0.6

Slope of b = 4.4/3.2

Slope of b = 1.375

Part 2.

Slope of road section = 2.5/152

Slope of road section = 0.0165 ≈ 0.02.

Part 3.

Slope of wheelchair ramp = 1.4/8

Slope of wheelchair ramp = 0.0175 ≈ 0.02.

Part 4.

a) The rise for graph a is 3 units.

The run for graph a is 5 units.

Slope of graph a = 3/5

Slope of graph a = 0.6

To find 6 x 1,295, you can use the expression (6 x 1,000) + (6 x 200) + (6 x 90) + (6 x 5). Here's a step-by-step explanation:

1. Multiply 6 by each part of the number 1,295:
  6 x 1,000 = 6,000
  6 x 200 = 1,200
  6 x 90 = 540
  6 x 5 = 30

2. Add the results from step 1:
  6,000 + 1,200 + 540 + 30 = 7,770

The actual distance between Los Angeles and San Francisco is 19,83,824 feet.

Given that, the distance between San Diego and San Francisco is 2,683,824 feet away and Los Angeles is about 700,000 feet closer to San Francisco than San Diego.

Distance is the total movement of an object without any regard for direction. We can define distance as how much ground an object has covered despite its starting or ending point.

The actual distance between Los Angeles and San Francisco = The distance between San Diego and San Francisco - The difference in distance.

= 2,683,824-700,000

The side length of each piece of quilt is approximately 24.06 inches.

In the given scenario, quilt square is cut on the diagonal to form triangular quilt pieces. The hypotenuse of the resulting triangles is 34 inches long. We have to determine the side length of each piece.

In a right triangle, according to the Pythagorean theorem, the sum of the squares of the legs is equal to the square of the hypotenuse.

So, we can use the Pythagorean theorem to find the length of the sides of the triangular quilt pieces.

The theorem states that a² + b² = c². In this case, c = 34 inches.

Let's assume that each quilt square has sides of length x inches.

When the square is cut diagonally, it is divided into two triangles with legs of length x inches.

According to the Pythagorean theorem, the length of the hypotenuse (34 inches) of each triangle is given by:

x² + x² = 34²2x² = 1156x² = 578x = √578 ≈ 24.06 inches

Answer:

x = -7/2

Step-by-step explanation:

-2(5x - 3) = 41

Distribute the -2 inside the parenthesis.

-10x + 6 = 41

Subtract 6 from both sides.

-10x = 35

Divide both sides by -10.

x = 35/-10

Simplify the fraction.

x = -7/2.

Proof:

-2(5x - 3) = 41

Substitute variable.

-2(5(-7/2) - 3) = 41

Multiply 5 and -7/2.

-2(-35/2 - 3) = 41

Turn 3 into a fraction with denominator 2.

-2(-35/2 - 6/2) = 41

Subtract 6/2 from -35/2.

-2(-41/2) = 41

Multiply -2 and -41/2.

41 = 41.

The domain will be D:{x ∈ R| x ≠ 4} and the range will be R:{y ∈ R| y ≠ 11}. Then the correct option is A.

The domain means all the possible values of x and the range means all the possible values of y.

The function is given below.

f(x) = (x² - 3x - 28) / (x + 4)

Simplify the function, then we have

f(x) = (x² - 7x + 4x - 28) / (x + 4)

f(x) = [x(x - 7) + 4(x - 7)] / (x + 4)

f(x) = [(x + 4)(x - 7)] / (x + 4)

f(x) = x - 7

The Domain of the function is all real numbers except 4. And the range of the function is all real numbers except 11.

The domain will be D:{x ∈ R| x ≠ 4} and the range will be R:{y ∈ R| y ≠ 11}. Then the correct option is A.

(a) The volume V of the box as a function of x is V = 4x^3-60x^2+200x

(b) The domain of V in interval notation is 0<x<5,

(c) The length L , width W, and height H of the resulting box that maximizes the volume is H = 2.113, W = 5.773, L= 15.773

(d) The maximum volume of the box is 192.421 cm^2.

In the given question,

A box is to be made out of a 10 cm by 20 cm piece of cardboard. Squares of side length cm will be cut out of each corner, and then the ends and sides will be folded up to form a box with an open top.

(a) We have to express the volume V of the box as a function of x.

If we cut out the squares, we'll have a length and width of 10-2x, 20-2x respectively and height of x.

So V = x(10-2x) (20-2x)

V = x(10(20-2x)-2x(20-2x))

V = x(200-20x-40x+4x^2)

V = x ( 200 - 60 x + 4x^2)

V = 4x^3-60x^2+200x

(b) Now we have to give the domain of V in interval notation.

Since the lengths must all be positive,

10-2x > 0 ≥ x < 5 and x> 0

So 0 < x < 5

(c) Now we have to find the length L , width W, and height H of the resulting box that maximizes the volume.

We take the derivative of V:

V'(x) = 12x^2-120x+200

Taking V'(x)=0

0 = 4 (3x^2-30x+50)

3x^2-30x+50=0

Now using the quadratic formula:

x=\(\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

From the equationl a=3, b=-30, c=50

Putting the value

x=\(\frac{30\pm\sqrt{(-30)^2-4\times3\times50}}{2\times3}\)

x= \(\frac{30\pm\sqrt{900-600}}{6}\)

x= \(\frac{30\pm\sqrt{300}}{6}\)

x= \(\frac{30\pm17.321}{6}\)

Since x<5,

So x= \(\frac{30-17.321}{6}\)

x= 2.113

So H = 2.113, W = 5.773, L= 15.773.

d) Now we have to find the maximum volume of the box.

V = HWL

V= 2.113*5.773*15.773

V = 192.421 cm^3
