Toby created a sculpture for art class using different-sized cubes. the smallest cube is 1.5 inches along each edge. the largest cube is 7.5 inches along each edge. how many of the smallest cubes would it take to fill the largest cube

Answers

Answer 1

It would take approximately 125 of the smallest cubes to fill the largest cube.

To determine the number of the smallest cubes that would fit inside the largest cube, we need to calculate the volume of both cubes.

The volume of a cube can be calculated by multiplying the length of one side by itself three times (since a cube has three equal sides). So, the volume of the smallest cube would be 1.5 x 1.5 x 1.5 = 3.375 cubic inches.

The volume of the largest cube can be calculated in the same way. The length of one side is 7.5 inches, so the volume would be 7.5 x 7.5 x 7.5 = 421.875 cubic inches.

To determine how many of the smallest cubes would fit inside the largest cube, we need to divide the volume of the largest cube by the volume of the smallest cube. So, 421.875 divided by 3.375 equals approximately 125.

The third approximation of the fourth root of 3 determined by calculating the third approximation of the right 0 of f(x) = x4 - 3, starting with Xo = 1, is (Round to four decimal places.) -

Answers

To use Newton's method to find the third approximation, X2, of the positive fourth root of 3, we follow these steps:

1. Define the function f(x) and its derivative, f'(x): f(x) = x^4 - 3 f'(x) = 4x^3

2. Start with an initial guess, X0 = 1.

3. Apply Newton's method formula to find the next approximations:

Xn+1 = Xn - f(Xn) / f'(Xn)

4. Calculate the first approximation, X1: X1 = X0 - f(X0) / f'(X0) X1 = 1 - (1^4 - 3) / (4 * 1^3) X1 = 1 - (-2) / 4 X1 = 1 + 0.5 X1 = 1.5

5. Calculate the second approximation, X2: X2 = X1 - f(X1) / f'(X1) X2 = 1.5 - (1.5^4 - 3) / (4 * 1.5^3) X2 = 1.5 - (5.0625 - 3) / 13.5 X2 = 1.5 - 2.0625 / 13.5 X2 = 1.5 - 0.15296 X2 ≈ 1.3470

50 families of four will be between 1980 and 1990 lbs.

Answers

The required probability is approximately 0.1253 or 12.53%.

We can use the central limit theorem to approximate the sampling distribution of the mean of the weights of clothes washed by 50 families of four. According to the central limit theorem, the sampling distribution of the mean will be approximately normal if the sample size is large enough (n > 30), regardless of the shape of the population distribution.

The mean of the sampling distribution of the mean will be equal to the population mean, which is 2000 lbs

[tex]SEM=\frac{\sigma}{\sqrt{n} }[/tex]

σ = population standard deviation

n = sample size.

[tex]SEM=\frac{187.5}{\sqrt{50} }[/tex]

= 26.5

Now we need to find the z-scores corresponding to the two values of the mean.

[tex]z_1=\frac{1980-2000}{26.5}[/tex]

= -0.75

[tex]z_2=\frac{1990-2000}{26.5}[/tex]

Using a standard normal table, we can find the probability that a z-score is between -0.75 and -0.38.

How many people can fit in the passenger car of 70 feet and a width of 9 feet

Answers

Approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet.

What is the volume of a car with a length of 70 feet and a width of 9 feet?

To determine the number of people who can fit in a passenger car with a length of 70 feet and a width of 9 feet, we need to consider the available space inside the car and the amount of space required per person.

Assuming that the passenger car is a rectangular box shape, the volume of the car can be calculated as follows:

Volume of car = Length x Width x Height

Since we are only interested in the number of people who can fit in the car, we will assume a standard height of 6 feet for simplicity. Therefore, the volume of the car can be calculated as follows:

Volume of car = 70 feet x 9 feet x 6 feet

Volume of car = 3,780 cubic feet

Next, we need to determine the amount of space required per person. This can vary depending on the seating arrangement and the size of the individuals, but as a general rule, we can estimate that each person requires approximately 10 to 12 cubic feet of space in a seated position.

Assuming we use the lower end of that estimate and allocate 10 cubic feet of space per person, we can calculate the number of people who can fit in the car as follows:

Number of people = Volume of car / Space per person

Number of people = 3,780 cubic feet / 10 cubic feet per person

Number of people = 378 people

Therefore, if we assume a standard height of 6 feet and allocate 10 cubic feet of space per person, approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet. However, it is important to note that this is just an estimate and the actual number of people who can fit in the car will depend on factors such as the seating arrangement and the size of the individuals.

What is the intermediate step in the form (x+a)^2=b as a result of completing the square for the following equation? x^2= -16x-37

Answers

The intermediate step in completing the square for x^2= -16x-37 is (x+8)^2=27.

To complete the square for the given equation, we need to add a constant value to both sides of the equation such that we can factor the left-hand side as a perfect square.

x^2 + 16x = -37

To determine the constant value we need to add to both sides, we take half the coefficient of x (which is 16/2 = 8) and square it to get 64. Then we add 64 to both sides of the equation:

x^2 + 16x + 64 = 27

Now we can factor the left-hand side as a perfect square:

(x + 8)^2 = 27

For f(x)=1/x^2 show there is no c such that f(1)-f(-1)=f'(c)(2).
Explain why the mean value theorem doesnt apply over the interval
[-1,1]"

Answers

Prerequisites for the MVT are not met due to the discontinuity and non-differentiability of f(x) at x = 0 within the interval [-1, 1].

Let's first understand the Mean Value Theorem (MVT). The MVT states that if a function is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a number c in (a, b) such that:

f'(c) = (f(b) - f(a)) / (b - a)

Now, consider the function f(x) = 1/x^2. This function is continuous and differentiable for all x ≠ 0. However, in the interval [-1, 1], the function is not continuous nor differentiable at x = 0. Therefore, the Mean Value Theorem does not apply to this interval.

Since the MVT does not apply, we cannot say there exists a c in the interval (-1, 1) such that f'(c) = (f(1) - f(-1)) / (1 - (-1)). This is because the prerequisites for the MVT are not met due to the discontinuity and non-differentiability of f(x) at x = 0 within the interval [-1, 1].

What is the height of the cone?

Answers

The height of the cone that the volume of a cylinder is twice the volume of a cone is 7.5 meters.

How to determine  the height of the cone

Let's first define some variables to represent the dimensions of the cone and cylinder. Let's use r for the radius of both shapes, h for the height of the cone, and 5 for the height of the cylinder.

The volume of a cone is given by V_cone = (1/3)πr^2h, and the volume of a cylinder is given by V_cylinder = πr^2h.

We are told that the volume of the cylinder is twice the volume of the cone:

V_cylinder = 2V_cone

Substituting the formulas for the volumes of the cone and cylinder, we get:

πr^2(5) = 2[(1/3)πr^2h]

Simplifying, we can cancel the π and the r^2 terms on both sides:

5 = (2/3)h

Multiplying both sides by 3/2, we get:

h = 7.5

Therefore, the height of the cone is 7.5 meters.

Choose. Right-left

Answers

The quotient of 4.082 and 10,000 is 0.000004082.

To find the quotient of 4.082 and 10,000, we need to divide 4.082 by 10,000. However, dividing a decimal by another decimal can be tricky, so we need to move the decimal point of the dividend (4.082) and the divisor (10,000) to make the division easier.

We can move the decimal point of 4.082 four places to the left to obtain 0.04082. This is because moving the decimal point to the left makes the number smaller. For example, moving the decimal point in 4.082 one place to the left gives us 0.4082, which is ten times smaller than 4.082. Moving the decimal point four places to the left gives us a number that is 10,000 times smaller than 4.082.

Similarly, we can move the decimal point of 10,000 four places to the right to obtain 100,000,000. This is because moving the decimal point to the right makes the number larger. For example, moving the decimal point in 10,000 one place to the right gives us 1,000, which is ten times larger than 10,000. Moving the decimal point four places to the right gives us a number that is 10,000 times larger than 10,000.

Now we can divide 0.04082 by 100,000,000, which gives us the quotient of 0.000004082. Therefore, to find the quotient of 4.082 and 10,000, we need to move the decimal point in 4.082 four places to the left and move the decimal point in 10,000 four places to the right, and then divide the resulting numbers.

y = (1/2)(4^x)

To find an exponential function that passes through the points (2,8) and (4,128), follow these steps:

Step 1: Recall the general form of an exponential function: y = ab^x
Here, 'a' and 'b' are constants that need to be determined using the given points.

Step 2: Substitute the first point (2,8) into the equation:
8 = ab^2

Step 3: Substitute the second point (4,128) into the equation:
128 = ab^4

Step 4: Divide the second equation by the first equation to eliminate 'a':
(128 = ab^4) / (8 = ab^2)
16 = b^2

Step 5: Solve for 'b':
b = √16
b = 4

Step 6: Substitute the value of 'b' back into the first equation:
8 = a(4^2)

Step 7: Solve for 'a':
8 = 16a
a = 8/16
a = 1/2

Step 8: Write the final exponential function using the values of 'a' and 'b':
y = (1/2)(4^x)

Lizzie came up with a divisibility test for a certain number m ≠ 1 : Break a positive integer n into two-digit chunks, starting from the ones place. (For example, the number 354764 would break into the two-digit chunks 35, 47, and 64 ) Find the alternating sum of these two-digit numbers, by adding the first number, subtracting the second, adding the third, and so on. (In our example, this alternating sum would be 35-47+64 = 52 ) Find m and show that this is indeed a divisibility test for n (by showing that n is divisible by m if and only if the result of this process is divisible by m)

Answers

If and only if the alternating sum of the two-digit chunks of a number n is divisible by m, then n is divisible by m.

What value of m makes the alternating sum of two-digit chunks of a positive integer n divisible by m?

Let's denote the two-digit chunks of n as a₁a₂, a₃a₄, ..., where a₁, a₂, a₃, a₄, ... are the digits from the ones place onward.

The alternating sum of these two-digit numbers is given by a₁a₂ - a₃a₄ + a₅a₆ - a₇a₈ + ...

We can rewrite n as (a₁a₂ × 100) + (a₃a₄ × 10) + (a₅a₆ × 1) + ...

The alternating sum expression can be written as (a₁a₂ × 100) - (a₃a₄ × 10) + (a₅a₆ × 1) - ...

If n is divisible by m, we have n ≡ 0 (mod m).

Rewriting n in terms of the alternating sum, we get (a₁a₂ × 100) - (a₃a₄ × 10) + (a₅a₆ × 1) - ... ≡ 0 (mod m).

Factoring out each two-digit chunk, we have (a₁a₂ - a₃a₄ + a₅a₆ - ...) ≡ 0 (mod m).

This implies that n is divisible by m if and only if the result of the alternating sum process is divisible by m.

m is the value that makes the alternating sum of the two-digit chunks of n a divisibility test for n.

Answers

The shopkeeper sold an average of 40.5 eggs per day during the given interval.

How to find the avg number of eggs?

To calculate the average number of eggs sold per day, add up the total number of eggs sold and divide by the number of days.

Total number of eggs sold = 42 + 49 + 61 + 35 + 27 + 36 + 50 + 34 + 31 + 40 = 405

Number of days = 10

Average number of eggs sold per day = 405 / 10 = 40.5

To add fractions with unlike denominators, we need to find the least common multiple of the denominators. In this case, the least common multiple of 3 and 4 is 12. So, we must find equivalents of each fraction with a denominator of 12.

How to add the fractions?

To add fractions with unlike denominators, we need to find the least common multiple of the denominators. In this case, the least common multiple of 3 and 4 is 12. So, we must find equivalents of each fraction with a denominator of 12.

Multiplying the numerator and denominator of 2/3 by 4, we get 8/12. On the other hand, multiplying the numerator and denominator of 1/4 by 3, we get 3/12.

Therefore, we can rewrite the sum as:

8/12 + 3/12

And adding the numerators, we get:

11/12

So, 2/3 + 1/4 = 11/12.

The final answer is a proper fraction, which means that the numerator is less than the denominator, and can be further simplified if necessary.
