The unit rate at which the baker uses baking powder to make dozens of cupcakes is 39/80 or 0.4875 teaspoons of baking powder per dozen cupcakes.

The unit rate refers to the comparison of two ratios that have 1 as their denominator. Unit rate is often used in calculations that compare two units. For instance kilometer/hour, meter/sec, and teaspoons/dozen as is the case in the above question.

To obtain the unit rate of the above question, we simply divide the teaspoons measurement by the quantity of cupcakes produced. This gives us:

By working with the given percentage, we will find that there are 1,050 students in the school.

First, we know that (66 + 2/3)% = (66.66...%) of the students are girls.

Then the remaining 33.33% are boys.

And we know that there are 350 boys, so the 33.33...% of the students is equal to 350.

So we can write the equations for percentages:

350 = 33.33%

X = 100%

Where X is the total number of students, to find X, we can take the quotient between these two equations:

X/350 = 100%/33.33%

X = 350/0.333... = 1,050

One of the options is c=d because matching angles are made and the same corners are congruent when a line joins two parallel lines.

In geometry, parallel lines are coplanar, straight lines that don't intersect anywhere. Parallel planes are those in the same three-dimensional space that never cross one another. Curves do not touch or intersect when they are parallel to one another and keep a predetermined minimum distance between them. Lines in a plane are considered to be parallel if their spacing is constant. Objects cannot cross parallel lines. Perpendicular lines are those that intersect at a precise angle of 90 degrees.

Due to vertical angles, A = d is also a possible answer. The outcome is that b+d=180 since b+c=180 and c=d, and b+d=180 as a result. Therefore, the answer is B, C, E, where a=d, c=d, and b+d=180.

You can find the complex roots of a 6th-degree polynomial by using approaches such as the rational root theorem.

The most common approach is to use the Rational Root Theorem, which can be used to determine the possible rational roots of the polynomial - these are the roots that can be expressed as a fraction with an integer numerator and an integer denominator.

Once you have identified these possible rational roots, you can then use the Synthetic Division algorithm to divide the polynomial with each of the rational roots to determine the actual roots of the equation.

Another approach is to use the Sturm’s Theorem, which can be used to determine the number of real and complex roots of the equation.

Finally, you can also use numerical methods, such as the Newton-Raphson method, to calculate the complex roots of the polynomial.

Step-by-step explanation:

The largest possible value of δ that guarantees |cos(x) + 2 sin(3x) − 1| < 0.

What is trignomentry ?

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. It is used to study the properties of angles,sines, cosines and tangents and circles.

We can start by using the Triangle Inequality to find an upper bound on |cos(x) + 2 sin(3x) − 1| in terms of |x − 0.5|:

|cos(x) + 2 sin(3x) − 1| <= |cos(x) − 1| + 2 |sin(3x)|

We know that |cos(x) − 1| <= |x − 0.5| and |sin(3x)| <= |3x|, since |sin(x)| <= |x| for all x. So we have ,

|cos(x) + 2 sin(3x) − 1| <= |x − 0.5| + 2|3x|

Now we can set this inequality equal to 0.5 and solve for |x − 0.5|:

|x − 0.5| + 2|3x| <= 0.5

|x − 0.5| <= 0.5 − 2|3x|

To find the largest possible value of δ, we need to find the maximum value of the right side of the inequality,

δ = 0.5 - 2|3x|

The maximum value of the right side of the inequality occurs when |3x| is at its smallest. Since |3x| >=0 for all x, the maximum value of δ is 0.5.

So , the largest possible value of δ that guarantees |cos(x) + 2 sin(3x) − 1| < 0.

Answer:

6 times to equals what [tex]\sqrt{36}[/tex]

Step-by-step explanation:

To find Root 6 one can refer to the methods of simplifying square roots. To simplify a square root, the number should be made as small as possible while still keeping it as a whole number. Mathematically this can be written as:

√a.b = √a * √b

To write this equation for the square root of 6 simplification, we will get:

√6= √2 * √3

This can be further simplified by substituting the values of root 2 and 3 (rounded to three decimal numbers) as:

√6 = 1.414 * 1.732

√6 = 2.449

Thus, this is the simplified version of the square root of 6. Similarly, we can also find square roots of any other whole numbers and find out their factors. After finding the factors, we usually convert them into the lowest divisible number, as we have done above. Thus, we have found the value of root 6. This method is the most popularly used method for finding square roots of any number. Apart from this, if we use a calculator we can find the exact value of this as well. The exact value will always be a decimal number as it is nearly impossible to find a positive whole integer as a root for non-rational numbers.

Another simplistic example of how roots work with one another is by figuring out the Square root of 6 plus square root of 6, and this is an interesting problem with a simplistic solution. Let us see this problem and its solution mathematically,

Sqrt (6) + Sqrt (6) = √6 + √6

√6 + √6 = 2√6

Thus, by substituting the value of root 6, we can find the required answer. Keeping this in mind, we can add these roots together to find the solution to the problem while keeping the base root under the radical sign constant. Hence, in this method, we can find solutions to such problems.

Answer:

[tex]26.666666667[/tex]

Step-by-step explanation:

To find the volume of a pyramid, you can use the formula:

Volume = (1/3) * base area * height

If the base is a rectangle, the base area is calculated by multiplying the length by the width.

Let's call the original length "L", the original width "W", and the original height "H".

The volume of the original pyramid is:

(1/3) * L * W * H = 40 cubic inches

If the length of the base is doubled, the new length is 2L.

The width is tripled, so the new width is 3W.

The height is increased by 50%, so the new height is 1.5H.

The volume of the new pyramid is:

(1/3) * (2L) * (3W) * (1.5H) = (2/3) * L * W * H = (2/3) * 40 cubic inches = 26.666666667 cubic inches.

So the volume of the new pyramid is approximately 26.666666667 cubic inches.

By using the rule of 3 simple, we will see that the value of the angle of the arc is 30°.

We know that an arc of 24 degrees has an arc length of 28cm, then we can write a relation:

24° = 28cm

(notice that it is just a relation so we can use the 3-simple-rule, that is not an equation, we only can do this because there is a linear relation between the angle and the length).

And for an angle x we have a length of 35cm, then we can write:

x = 35cm

Now we can take the quotient of these two equations to get:

x/24° = (35cm/28cm)

Solving for x:

x = (35cm/28cm)*24° = 30°

That is the angle of the arc.

Answer:

387 in³

Step-by-step explanation:

Volume of the solid 8" cube = 8³ = 512

The "empty space" volume of the 5" hole = 5³ = 125

Subtract the volume of the hole from the solid cube:

512 - 125 = 387 in³  (that's what is left)

The equivalent equation after combining like terms is x-7=1. To solve this equation, simply add 7 to both sides of the equation and you will get x=8.

An equivalent equation is an equation that is mathematically equal to another equation, meaning that both equations have the same solutions. For example, the equation "2x + 5 = 11" is equivalent to the equation "2x = 6". Both equations have the same solution, x = 3.

This is done by subtracting 2x from both sides, and then adding 9 to both sides. Doing so eliminates the -2x and -9 terms, leaving just x on one side, and 7 on the other.

The solution to the initial value problem is y(t) = (3/2)te^(2t) + e^(-t) + 1.

To find the solution to the initial value problem, we need to first find the general solution to the differential equation. To do this, we can use the method of integrating factors. We can find the integrating factor is e^∫p(t)dt = e^t, multiplying both sides by it, we get e^ty' - e^ty = 3te^(t+1). Integrating both sides with respect to t, we get e^t*y = (3/2)te^(2t) + C. Solving for y, we get y(t) = (3/2)te^(2t) + Ce^(-t).

Next, we use the initial condition to find the value of C. We know that y(0) = 1, substitute this into the general solution, and we get 1 = (3/2)0e^(2*0) + Ce^(0) = C.

Therefore, the solution to the initial value problem is y(t) = (3/2)te^(2t) + e^(-t) + 1.
