alfa bought a brand new box of sugar he wants to transfer it to a new container will there be any sugar left over after filling the new container explain show work

Answers

There will be no sugar left after the transfer.

Given are two containers in the shape of a rectangular prism and the second one is a composite solid of rectangular prism and a triangular prism,

We need to compare the volume of both prisms,

For the volume of the composite solid we will add the volume of both solids = 1/2 × base area × height + length × width × height

= 1/2 × 300 × 8 + 12 × 12 × 25

= 1200 + 3600

= 4800 cm³

Now the volume of the old container (rectangular prism - the blue one) = length × width × height = 30 × 20 × 8 = 4800 cm³

Since the volume of both old and new container is same, so there will be no sugar left after the transfer.

Hence there will be no sugar left after the transfer.

Edgardo created a rectangular prism with a square base. The volume of the prism is 45 cubic inches. The dimensions of the prism are all whole numbers. What is the height of the prism​

Answers

The calculated height of the prism​ is 5 inches

How to calculate the height of the prism​

from the question, we have the following parameters that can be used in our computation:

Volume = 45 cubic inches

Base = square

The height of the prism​ is calculated as

Volume = Base length² * Height

substitute the known values in the above equation, so, we have the following representation

Base length² * Height = 45

So, we have

Base length² * Height = 3² * 5

The measures of each of the arcs are: 16. m(MN) = 72°; 17. m(NQR) = 180°; 18. m(NQ) = 108°; 19. m(MRP) = 193°; 20. m(QR) = 72°; 21. m(MR) = 108°; 22. m(QMR) = 288°; 23. m(PQ) = 13°; 24. m(PRN) = 265°; 25. m(MQN) = 288°.

How to Determine the Measure of Each Arc?

Recall that in a circle, the measure of an intercepted arc is always the same or equal to the measure of the central angle it subtends.

Therefore, we have:

16. m(MN) = 72° (based on the vertical angles and inscribed angle theorems).

17. arc NQR is an half circle, therefore:

m(NQR) = 180°

18. m(NQ) = 180 - 72 = 108°

19. m(MRP) = 180 + (180 - 72 - 95)

m(MRP) = 193°

20. m(QR) = 72°

21. m(MR) = 180 - 72 = 108°

22. m(QMR) = 360 - 72

m(QMR) = 288°

23. m(PQ) = 180 - 72 - 95

m(PQ) = 13°

24. m(PRN) = 360 - 95

m(PRN) = 265°

25. m(MQN) = 360 - 72

m(MQN) = 288°

A student takes a true-false test that has 8 questions and guesses randomly at each answer. Let X be the number of questions answered correctly. Find P(5)

Answers

The student's chances of answering all five questions correctly are 7/64.

This is an example of a binomial distribution, where each question has a probability of 1/2 of being answered correctly and there are 8 independent trials.

The probability mass function for a binomial distribution is:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n is the number of trials, p is the probability of success, and k is the number of successes.

In this case, n = 8, p = 1/2, and we want to find P(X = 5).

P(X = 5) = (8 choose 5) * (1/2)^5 * (1/2)^(8-5)

P(X = 5) = (8 choose 5) * (1/2)^8

Using the formula for combinations, (n choose k) = n! / (k! * (n-k)!) we get:

P(X = 5) = (8! / (5! * 3!)) * (1/2)^8

P(X = 5) = 56 * 1/256

P(X = 5) = 7/64

At the city museum, child admission is $5.10 and adult admission is $8.20. On Wednesday, 176 tickets were sold for a total sales of $1201.40. How many child tickets were sold that day?

Answers

Answer:

So 98 adult tickets were sold.

Step-by-step explanation:

Let's use a system of equations to solve the problem.

Let x be the number of child tickets sold and y be the number of adult tickets sold. Then we have:

x + y = 176 (equation 1)

5.10x + 8.20y = 1201.40 (equation 2)

We can solve for x by isolating y in equation 1 and substituting into equation 2:

y = 176 - x (from equation 1)

5.10x + 8.20(176 - x) = 1201.40 (substitute into equation 2)

5.10x + 1443.20 - 8.20x = 1201.40

-3.10x = -241.80

x = 78

Therefore, 78 child tickets were sold that day. We can find the number of adult tickets by substituting x into equation 1:

78 + y = 176

y = 98

So 98 adult tickets were sold.

Explain which way you like better and why.
The surface area increases by
cm².
13 cm
30 cm
8.7 cm

Answers

Answer:

  8.68 cm²

Step-by-step explanation:

You want the increase in surface area of a box with length and width 13 cm and 8.7 cm when the height is increased from 30 cm by 0.2 cm.

Area

The increase in area is effectively the lateral area of the prism whose length and width are the same, but whose height is 0.2 cm. That is ...

  A = Ph = 2(L+W)h

  A = 2(13 cm +8.7 cm)(0.2 cm) = 8.68 cm²

The surface area increases by 8.68 cm².

Alternate solution

We can find the total area of the box with the different dimensions, then subtract the original area from the increased area.

  A = 2(LW +H(L+W))

  A1 = 2(13·8.7 +30(13 +8.7)) = 1528.2 cm²

  A2 = 2(13·8.7 +30.2(13 +8.7)) = 1536.88 cm²

The increase in area is 1536.88 -1528.2 = 8.68 cm².

We prefer the first solution, as it requires a lot less arithmetic.

The attraction force between two particles is inversely proportional to the square of the distance between them. If the force is F when the distance between them is 2r and the force is kF when the distance is 3r, find the value of k. ​

Answers

Let's denote the force between the two particles as F and the distance between them as d. We know that the force is inversely proportional to the square of the distance, which can be expressed as:

F ∝ 1/d^2

Using proportionality, we can write:

F = k/d^2

where k is a constant of proportionality.

If the distance between the particles is 2r, then we have:

F = k/(2r)^2 = k/4r^2

If the distance between the particles is 3r, then we have:

kF = k/d^2 = k/(3r)^2 = k/9r^2

We can then set these two expressions equal to each other and solve for k:

k/4r^2 = k/9r^2

Multiplying both sides by 36r^2 (the least common multiple of 4r^2 and 9r^2), we get:

9k = 4k

Simplifying, we get:

k = 4/9

Therefore, the value of k is 4/9.

Part A. Write the equation 5=10x−5y in slope-intercept form.
Part B. Identify the y-intercept.
please write both answers

Answers

Part A. To write the equation 5=10x-5y in slope-intercept form, we need to isolate y on one side of the equation. First, we'll add 5y to both sides of the equation:
5 + 5y = 10x
Next, we'll subtract 5 from both sides of the equation:
5y = 10x - 5
Finally, we'll divide both sides of the equation by 5:
y = 2x - 1
Therefore, the equation 5=10x-5y in slope-intercept form is y = 2x - 1.

Part B. The y-intercept is the point where the line crosses the y-axis. In slope-intercept form, the y-intercept is the constant term. In this equation, the constant term is -1. Therefore, the y-intercept is -1.

The difference between 344 and 15 is 329. Since we want to count the number of odd integers between 15 and 344, we can divide this difference by 2 and round up since we know that every other integer is odd:

Number of odd integers = (difference between endpoints) / 2 rounded up
Number of odd integers = 329 / 2 rounded up
Number of odd integers = 165

Therefore, there are 165 odd integers between 15 and 344.

2) In his book "Concerning the Spiritual in Art," Kandinsky expressed his belief that art should go beyond mere representation of the physical world and instead aim to express the spiritual and emotional aspects of human experience. He wrote that "the artist must be blind to distinction between 'recognized' or 'unrecognized' conventions of form, deaf to the transitory teaching and demands of his particular age.

He must watch only the trend of the inner need, and hearken to its words alone" (Kandinsky, 1977, p. 8).

Answers

The inverse of function f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.So, the correct option is D.

To find the inverse of a function, we switch the x and y variables and solve for y. So, if f(x) = -2, we have:
x = -2
y = f(x) = -2
Switching x and y, we get:
x = f¯¹(y)
y = -2
Solving for f¯¹(y), we get:
f¯¹(y) = 2y + 3
Therefore, the inverse of f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.
To find the inverse of a function, we need to swap the input (x) and output (f(x)), and then solve for the new input. Given f(x) = -2, let's find the inverse:
1. Swap the input and output: x = -2
2. Solve for the new input: Since the function f(x) is a constant function and doesn't involve x, the inverse of f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.
Therefore, Option D is the correct inverse of f(x).

f(-3) = 3(-3)⁴ - 4(-3)³ + 3(-3)² - 5(-3) - 3

f(-3) = 3(81) + 4(27) + 3(9) + 15 - 3

f(-3) = 243 + 108 + 27 + 15 - 3

f(-3) = 390

For x = 4;

f(4) = 3(4)⁴ - 4(4)³ + 3(4)² - 5(4) - 3

f(4) = 3(256) - 4(64) + 3(16) - 20 - 3

f(4) = 768 - 256 + 48 - 20 - 3

f(4) = 537

Therefore, for the mapping of the function f(x) = 3x⁴ - 4x³ + 3x² - 5x - 3 for the values of x: -3 and 4 we have the results 390 and 537.

Find the axis of symmetry.

f(x) = -(x - 2)(x + 4)

a) x = 2
b) y = -1
c) y = 8
d) x = -1

Answers

The axis of symmetry of the given quadratic function f(x) = -(x - 2)(x + 4) is x = -1.

What is the axis of symmetry of the function?

Given the function in the question:

f(x) = -(x - 2)(x + 4)

To find the axis of symmetry, first expand  quadratic function f(x) = -(x - 2)(x + 4).

f(x) = -(x - 2)(x + 4)

f(x) = (-x + 2)(x + 4)

f(x) = -x(x + 4) + 2( x + 4 )

f(x) = -x² - 4x + 2x + 8

Collect and add like terms

f(x) = -x² - 2x + 8

To find the axis of symmetry, we can use the formula:

x = -b/2a

Where a = -1 and b = -2.

Substituting these values, we get:

x = -(-2) / 2(-1)

Simplify

x = 2 / -2

x = -1

Therefore, the the axis of symmetry is x = -1.

Option D) x = -1 is the correct answer.

9. A farmer wants to construct a fence to create a square horse corral with an area of 10,000 square feet. Fence posts along each side will be 10 feet apart at their center. Including the four corner posts, how many posts are needed to construct the fence?​

Answers

the total number of posts needed is, 56

Since, we know that the area of the horse corral is 10,000 square feet.

So, it is a square corral, we can find the length of each side by taking the square root of the area, which is 100 feet.

Now, For the total number of posts needed, we need to calculate the perimeter of the corral.

Since there are four sides of equal length, the perimeter of the corral is 4 times the length of one side.

Therefore, the total perimeter is 400 feet.

Now, we need to find the number of posts needed.

We know that each post is placed 10 feet apart along the sides of the corral.

Since there are 4 sides, we need 3 intervals of 10 ft between each post, which gives us a total of 4 posts for every 30 feet of fencing.

Therefore, the total number of posts needed is,

= (400 / 30) x 4 + 4

= 56 posts.

Adrian wants to purchase an electric keyboard. The price of the keyboard at Macelli’s, with tax, is $2,400. He can save $150 per month. How long will it take him to save for the keyboard? (round to a full month).

Answers

It will take Adrian 16 full months to save enough money for the electric keyboard.

- Price of the keyboard (with tax) at Macelli's: $2,400
- Adrian's monthly savings: $150
We need to find how long it will take Adrian to save for the keyboard. To do this, we'll divide the total cost of the keyboard by his monthly savings and round up to the nearest full month.
Step 1: Divide the total cost by monthly savings.
Time (in months) = (Total Cost) / (Monthly Savings) = ($2,400) / ($150)
Step 2: Calculate the result.
Time (in months) = 16
So, it will take Adrian 16 full months to save enough money for the electric keyboard.

How to write the regression equation and determine the correlation coefficient?

In this scenario, the x-values (x) would be plotted on the x-axis of the scatter plot while the y-values (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the x-values (x) and y-values (y), the exponential equation and the correlation coefficient are given by:

[tex]y = 535.02(1.15)^x[/tex]

Correlation coefficient, r = 0.9973006 ≈ 1.0

In conclusion, we can logically deduce that there is a strong correlation between the data because the correlation coefficient (r) is is greater than 0.7;

0.7<|r| ≤ 1.0   (strong correlation)

The given matrix has no solution. Therefore, option A is the correct answer.

From the given matrix,

[tex]\left[\begin{array}{ccc}1&1&-4\\-2&-1&6\\-5&-3&16\end{array}\right]\left[\begin{array}{ccc}x\\y\\x\end{array}\right] = \left[\begin{array}{ccc}6\\-10\\-26\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}x+y-4z\\-2x-y+6z\\-5x-3y+16z\end{array}\right] =\left[\begin{array}{ccc}6\\-10\\-26\end{array}\right][/tex]

x+y-4z=6  -------(i)

-2x-y+6z=-10 ---------(ii)

-5x-3y+16z=-26 ---------(iii)

Multiply equation (i) by 2, we get 2x+2y-8z=12 ---------(iv)

Add equation (ii) and (iv), we get

-2x-y+6z+2x+2y-8z=-10+12

y-2z=2 ---------(v)

Multiply equation (i) by 5, we get

5x+5y-20z=30 ---------(vi)

Add equation (vi) from (iii), we get

5x+5y-20z+(-5x-3y+16z)=30-26

5x+5y-20z-5x-3y+16z=4

2y-4z=4

y-2z=2 ---------(vii)

From equation (vi) and (vii), we understood the matrix has no solution
