The total cereal mixture is 45 kilograms

Solution:

Given that, cereal mixture contains Almond, Wheat, and Corn in the ratio of 3:5:7

Therefore,

Almond : Wheat : Corn = 3 : 5 : 7

Let the almond present be 3x

Let the wheat present be 5x

Let the corn present be 7x

Therefore,

Total cereal mixture = 3x + 5x + 7x

Total cereal mixture = 15x

Given that mixture contains 9 kg of almond

Almond = 9

We know that,

Almond present = 3x

3x = 9

x = 3

Therefore,

Total cereal mixture = 15x = 15(3) = 45

Thus total cereal mixture is 45 kilograms

Answer: No

Step-by-step explanation: In order to decide whether the given fractions are equivalent, first write each fraction in lowest terms.

A fraction is written in lowest terms if the greatest common factor of the numerator and the denominator is 1.

So for our first fraction, 4/9, since the greatest common factor of 4 and 9 is 1, we know that are fraction is already written in lowest terms.

For our second fraction however, since the greatest common factor of 20 and 36 is 4, we must divide both the numerator and the denominator by 4 to write our fraction in lowest terms. This gives us 5/9.

Since 5/9 is bigger than 4/9, te fractions are not equivalent so no, 4/9 is not equivalent to 20/36.

Answer:

The percent increase is 18.75%.

Step-by-step explanation:

Given:

Amber got a raise, and her hourly wage increased from $8 to $9.50.

Now, to find percent increase.

Previous wage = $8.

Wage raised = $9.50.

So, to get the increased wage we subtract the previous wage from the wage raised:

[tex]\$9.50-\$8=\$1.50.[/tex]

Now, to get the percent increase:

[tex]\frac{1.50}{8} \times 100[/tex]

[tex]=\frac{150}{8}[/tex]

[tex]=18.75\%.[/tex]

Therefore, the percent increase is 18.75%.

The percent increase in Amber's hourly wage from $8 to $9.50 is 18.75%.

To find the percent increase in Amber's hourly wage, you can follow these steps:

⇒ $9.50 - $8 = $1.50.

⇒ $1.50 ÷ $8 = 0.1875.

⇒ 0.1875 × 100 = 18.75%.

Therefore, the percent increase in Amber's hourly wage is 18.75%.

The best approximation for the measure of angle XYZ is 39.8° ⇒ 2nd answer

Step-by-step explanation:

Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle

The trigonometry ratios of the angle BAC, the opposite side to this angle is BC and the adjacent side to it is AB are

In Δ XYZ

∵ ∠ YXZ is a right angle

∴ The hypotenuse is YZ

∵ The adjacent side to ∠XYZ is XY

∵ The opposite side to ∠XYZ is XZ

∵ YX = 12 units

∵ XZ = 10 units

- Use tan ratio to find the measure of the angle because you

   have the adjacent and opposite sides of the angle XYZ

∵ m∠XYZ is x

∵ [tex]tan(x)=\frac{XZ}{XY}[/tex]

∴ [tex]tan(x)=\frac{10}{12}[/tex]

- To find x use the inverse of tan(x)

∵ [tex]x=tan^{-1}(\frac{10}{12})[/tex]

∴ x = 39.8°

∴ m∠XYZ = 39.81°

The best approximation for the measure of angle XYZ is 39.8°

Step-by-step explanation:

x^2 + y^2 – 14x + 10y = 250

x^2 -14x + y^2 + 10y = 250

x^2 - 14x + (-7)^2 + y^2 + 10y + (5)^2 = 250 + (-7)^2 +  (5)^2

(x-7)^2 + (y + 5)^2 = 250 + 49 + 25

(x-7)^2 + (y + 5)^2 = 324

Comparing with the general circle (x - b)^2 + (y - a)^2 = r^2

To solve for D in the equation z = a/b + c/d, subtract a/b from both sides, combine fractions on the left side, cross multiply, and finally solve for d by dividing both sides by (bz - a).

Explanation:

To solve for D in the equation z = a/b + c/d, you need to isolate d on one side of the equation. Here's how you can do it:

When a = 2.658653234, b = 0.179825026, c = -54.56945917, and z = 17.98260265, you would substitute these values and calculate d accordingly, leading to a numerical solution for d.

Therefore the minimum mileage for which Company A will charge more than Company B is 251 miles.

Step-by-step explanation:

i) let x be the number of miles driven

ii) If Joe rents the truck from Company A the Joe will pay Company A

  = $0.8x

iii) If Joe rents the truck from Company B then Joe will pay Company B

   = $50 + $0.6x

iv) the mileage for which the rents of both companies will be equal is given by

  $0.8x = $50 + 0.6x

Therefore 0.2x = $50

Therefore x = [tex]\frac{50}{0.2} = \frac{500}{2} = 250[/tex] miles.

Final answer:

The provided expressions each represent different algebraic operations. The first involves rearranging a quadratic equation into standard form, while the second describes the line and graph representation of a linear equation. The third is the application of the product rule to find the derivative of an equation.

Explanation:

To determine which algebraic expression is represented by the model, the given expression of 3x +3+x²+x=24 needs to be simplified and put into standard form. This involves combining like terms and rearranging to achieve the form ax² +bx+c= 0. After combining terms involving x and rearranging, you should subtract 24 from both sides of the equation to set it equal to zero.
On the other hand, the equation y = 9 + 3x represents a linear relationship with a slope (m) of 3 and a y-intercept (b) of 9. Constructing a table or graph of this equation by plugging in different x-values and calculating y reveals a line on a graph. The given equation has no terms that would suggest it represents a model that includes x², thus it is not a quadratic equation and does not match the first expression.

When dealing with the derivative of the equation (x³)'(1 + x²)−¹ + x³ [(1 + x²)−¹]', according to the product rule, this simplifies to 3x² (1 + x²)−¹ + x³ [-(1 + x²)−²(2x)]. Simplifying further, you obtain a final form that involves squaring the binomial (1+x²).
These three examples of algebraic manipulation showcase different types of operations needed to simplify and derive equations for specific purposes.

Answer:24 oringal width

49 original length

Step-by-step explanation:

The original dimensions of the rectangular piece of metal were 30 inches by 55 inches, based on the given conditions of making an open box and its volume.

In this problem, we have a rectangular piece of metal that is being converted into an open box. Note that the length of the rectangular piece is 25 in longer than its width.

When squares with side 5 in are cut from the corners and the sides are folded up to make the open box, the dimensions of the box formed become length = w+25-10, width = w-10, and height = 5, where w is the width of the original rectangular piece.

The volume of a box is given by the product of length, width, and height. So if the volume of this box is given as 2730 cubic inches, we can write the equation (w-10)(w+15)(5)=2730.

This can be solved to give w=30 (excluding the negative solution as unrealistic for this context). Therefore, the original dimensions of the metal piece were 30 in (width) by 55 in (length).
