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.

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: 29/48

Step-by-step explanation:

If she spent 5/12 of 1200, she's left with 7/12 of 1200 which is 700. If she spends 1/4 of that, she has 3/4 of it left. 3/4 x 700 is 525. 525 + 250 is equal to 725. To simplify 725/1200, divide both sides by 25 to get 29/48.

The t-distribution for developing a confidence interval for a mean has n - 1 degrees of freedom.

The t-distribution is used to develop a confidence interval for a mean. In order to do this, the degrees of freedom (df) of the t-distribution must be known. The formula for degrees of freedom is df = n - 1, where n is the sample size. Therefore, the t-distribution for developing a confidence interval for a mean has n - 1 degrees of freedom. The t-distribution is a form of the normal distribution that takes into account the uncertainty in estimating the population mean from a sample. The t-distribution is used when the population standard deviation is unknown, and the sample size is relatively small. The shape of the t-distribution will depend on the degrees of freedom, which is determined by the sample size. The larger the sample size, the larger the degrees of freedom and the closer the t-distribution will be to the normal distribution.

The ratio of the surface area of Theo's sphere to the total surface area of Akshay's spheres is 25:8.

We have , The radius of Theo's sphere , R = 5

As we know that,

Surface area of sphere , A₁ = 4πr²

where r --> radius of sphere

So, Surface area of Theo's sphere = 4πR² = 4×π (5)² = 100π

The radius of Akshay's two spheres,

R₁ = R₂ = 2

Surface area of Akshay's first sphere

= 4πR₁²

= 4×π ( 2)² = 16π

similarly, surface area of Akshay's second sphere = 4πR₂² = 4×π(2)² = 16π

Total surface area of Akshay's two spheres, A₂ = 16π + 16π = 32π

Then, the ratio of the surface areas of spheres, A₁ : A₂ = 4π(R)² :4π(R₁² +R₂²)

=> A₁ : A₂ = 100π : 32π

=> A₁ : A₂ = 25 : 8

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.

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.

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.

The proportion ratio of Bani and Ylang-ylang is 7:14

A proportion ratio is a way of expressing the relationship between two or more quantities in terms of a ratio. It is a way of comparing the relative sizes of different quantities, and it is often used to describe the relative proportion of different components of a whole.

The proportion of Bani trees to Ylang-ylang trees would be 7:10, or 7/10. If we add 4 more trees to the Ylang-ylang trees, there would be 14 Ylang-ylang trees and 7 Bani trees. The proportion of Bani trees to Ylang-ylang trees would be 7:14, or 7/14.

You can also represent this proportion ratio in the form of fractions or as a percentage. To convert the fraction 7/14 to a percentage, you would multiply it by 100, which would give you 50%. This means that the proportion of Bani trees to Ylang-ylang trees is 50% Bani and 50% Ylang-ylang.

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%
