The percentage change in the amount of sugar used is 38.8%

Sugar used the previous week = 42. 5 pounds

Sugar used this week = 26 pounds

Calculating the difference between two amounts of sugar -

Sugar used the previous week - Sugar used this week

= 42.5 - 26

= 16.5 pounds.

To calculate the change in percentage, the differential amount is to be multiplied by 100 to express the result as a percentage, which is required to determine the percent change in the amount of sugar utilised.

Calculating the per cent change -

Differential sugar amount / Sugar used in previous week x 100

= 16.5 / 42.5 x 100

= 38.8%.

An isosceles right triangle has a right angle (90 degrees) and two congruent acute angles(45 degrees).

A triangle's isosceles quality is characterised by its two equal-length sides. The third side which is not equally long as the first two is referred to as the base. The legs are the two equal sides. The vertex opposite the base has an obtuse, acute, or straight angle, and the angles at that vertex are congruent.

A right angle of 90 degrees and two congruent acute angles make up an isosceles right triangle (45 degrees). A right triangle has three angles, two of which are acute and one of which is always a right angle (90 degrees). Because the two legs of an isosceles right triangle are congruent, the two acute angles are likewise congruent. An isosceles right triangle, therefore, has angles of 90 degrees, 45 degrees, and 45 degrees.

The y-intercept is (0,9)

The y-intercept of a linear equation in the form of y = mx + b is represented by the constant term, b. In this case, the y-intercept is 9. This means that the line represented by this equation crosses the y-axis at the point (0, 9).

To find the y-intercept, we can substitute x = 0 into the equation, y = 10x + 9 and we get:

y = 10(0) + 9

y = 9

So the y-intercept is (0,9)

A linear equation is an equation that can be written in the form of y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (the point where the line crosses the y-axis).

Answer: The graph that could be the graph of f(x) is a parabola that opens upwards, with a vertex at (2,-4) and x-intercepts at x = -1 and x = 4. Since the degree of the polynomial function f(x) is 3 and the roots are -1, 0, and 4, the polynomial function is a cubic function and its graph is a parabola.

The roots of a polynomial function are the x-coordinates of the x-intercepts of the graph of the function. Therefore, since the roots of the equation f(x) = 0 are -1, 0, and 4, the graph of f(x) will have x-intercepts at x = -1 and x = 4.

The fact that the vertex is at (2, -4) mean that the parabola will open upwards and pass through the point (2, -4)

It's important to note that, if the polynomial function has a degree greater than 3, there may be multiple graphs that could represent the polynomial function, as long as they have the same roots.

No, an isosceles triangle is not always 90 degrees

Two of a triangle's sides must be the same length for the triangle to be considered isosceles. The third side, which is not equally long as the first two, is referred to as the base. The angle at the vertex opposite to the base is obtuse, acute, or right angle and the angles at the vertex opposite to the base are congruent.

Not all angles in an isosceles triangle are 90 degrees. A triangle with equal-length sides is called an isosceles triangle, although the angles at the vertex opposite the equal sides might be of any degree. The isosceles right triangle, the golden triangle, the faces of bipyramids, and some Catalan solids are all examples of isosceles triangles.

The height of the actual glass is equal to 10 cm.

In Geometry, a scale factor is the ratio of two corresponding side lengths or diameter in two similar geometric figures such as drinking glasses, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.

Mathematically, the scale factor of a geometric figure can be calculated by dividing the dimension of the image by the dimension of the pre-image (original figure):

Scale factor = Dimension of image (new figure)/Dimension of pre-image(original figure)

Scale factor = 2/2.5

For the height of the actual glass, we have:

2/2.5 = 8/x

x = (2.5 × 8)/2

x = 20/2

Yes, it is possible to order a list of numbers by their number of words. To do this, you will need to count the number of words in each number, then order them in ascending or descending order based on this number.

Here is an example of how to do this:

1. Count the number of words in each number. For example, the number “twenty-nine” has two words (“twenty” and “nine”).

2. Order the numbers from least to greatest or greatest to least based on the number of words. For example, “nine” has one word, so it would come before “twenty-nine” which has two words.

3. Place the numbers in order from least to greatest or greatest to least.

This method can also be used to order numbers that are written in words or numbers that are written in numerals. However, if the numbers are written in numerals, you will need to convert them to words before you can count the number of words.

Sublimation is the straight transition from a solid state of materials to a vapor state upon heating (without becoming liquid).

When a substance changes from one state to another, as as from a solid to a gas, this transition, transformation, or conversion is referred to as sublimation.

Sublimation is the procedure through which a material is converted from its solid to gaseous phase without moving to its liquid form. At a temperature and pressure below the substance's triple point, this process, an endothermic phase transition, takes place. The opposite of this process, in which a gas is transformed straight into a solid state, is desublimation or deposition.

An inequality in math is a statement that compares two values using an inequality sign. Inequalities can be used to describe a range of values, such as greater than, less than, greater than or equal to, and less than or equal to.

For example, the inequality 7 > 5 states that the value 7 is greater than the value 5. This type of inequality is known as a strict inequality, meaning that the values must be greater or less than one another in order for the statement to be true.

Another type of inequality is a non-strict inequality, which uses the symbols “≥” and “≤”. Here, "greater than or equal to" and "less than or equal to" are the appropriate definitions. For example, the inequality 5 ≤ 7 states that the value 5 is less than or equal to the value 7. This type of inequality allows the values to be equal to each other, rather than just strictly less or greater than one another.

Inequalities are used in a variety of mathematical equations, including linear equations, quadratic equations, and polynomial equations. They can also be used to solve for unknown values, such as the solution to an equation. Inequalities are also used to describe ranges of values, such as the range of numbers on a number line.

Answer:

  75.5°

Step-by-step explanation:

You want the angle between a 50 pound force and a 75 pound force given that their resultant is a 100 pound force. Force 1 is aligned with the +x axis, and Force 2 is in the first quadrant.

The forces and their resultant form a triangle such that the angle opposite the resultant is the supplement of the angle between the forces. We can find the angle opposite the resultant using the law of cosines:

  c² = a² +b² -2ab·cos(C)

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos(a² +b² -c²)/(2ab) = arccos((50² +75² -100²)/(2·50·75))

  C = arccos(-1875/7500) = arccos(-1/4) ≈ 104.48°

The angle between the vectors is the supplement of this:

  angle12 = 180° -104.48° = 75.52° ≈ 75.5°

The angle between the forces is about 75.5°.

Let P and Q represent the intersections of two triangle sides. Consequently, the third side's length is divided in half by the length of the section that connects P and Q.

Vega is attempting to prove that the segment joining the midpoints of two sides of a triangle is equal to half the length of the third side. To do this, she must first identify the two midpoints of any given triangle. Let P and Q be the midpoints of two sides of the triangle. She must then demonstrate that the segment connecting P and Q is equal to half the length of the third side. To do this, Vega must calculate the distance between P and Q and then compare it to the length of the third side. If the two measurements are equal, then Vega will have proven her point.
