Answers
The only statements that is true about the information on the table are:
The ratio of students who wish they had flight to those who wish for invisibility -Ratio 2:3. All other statements/ratios are false/incorrect.How do we get the ratio of students who wish they had flight to those who wish for invisibility?
Ratio is simple math.
The number of people who wish for invisibility are: 12 ; while
The number of people who wish for flight are: 8
Thus the ratio will be given as:
8/12 further simplified by dividing by 4, we have
(8/4) : (12/4)

a slice of pizza supplies 217 kcal (217 cal). if a person weighing 140 lb expends 80 kcal per mile when walking at 2.0 miles per hour, approximately how long will it take to use up the calories from the pizza?
Answers
The required time consumed to burn the calories gained from the slice of pizza is 1.36 hr.
Given that,
A slice of pizza supplies 217 kcal (217 cal). if a person weighing 140 lb expends 80 kcal per mile when walking at 2.0 miles per hour.
here,
1 mile = 80 kcal used,
1 kcal used = 1/80 mile
217 kcal used = 217/80 mile = 2.71 miles
Now,
2 miles = 1 hour,
2.71 miles = 2.71/2 hours
2.71 miles = 1.36 hours
Thus, the required time consumed to burn the calories gained from the slice of pizza is 1.36 hr.

Given matrices A of mxn B of pxq C = AB Which of the following statements about C is true? C exists only if n = p C does not exist C exists only if m = q C is always a square matrix
Answers
The statement that is true about matrix C, which is the product of matrices A and B (C = AB), is that C exists only if n = p.
For matrix multiplication to be defined, the number of columns in matrix A must be equal to the number of rows in matrix B. In other words, if A is an mxn matrix and B is a pxq matrix, then the product AB will only exist if the number of columns in A (n) is equal to the number of rows in B (p). If n is not equal to p, then the product AB cannot be calculated, and C does not exist. Therefore, the correct statement is that C exists only if n = p. It is important to note that this condition is necessary for the matrix product to be defined, but the resulting matrix C may or may not be square depending on the dimensions of A and B.

We are asked to compute the matrix U, formed by concatenating u1 and u2 as columns, and to compute U'U and UUT. Additionally, we are asked to compute the projection of y onto the subspace spanned by u1 and u2, as well as (uuT)y and (UU)y.
We can compute the matrix U by concatenating u1 and u2 as columns. Thus, we have:
U = | 2/3 -2/3 |
| 2/3 1/3 |
| 1/3 2/3 |
Next, we can compute U'U and UUT as follows:
U'U = | 2 0 |
| 0 2 |
UUT = | 8/9 4/9 2/9 |
| 4/9 4/9 4/9 |
| 2/9 4/9 8/9 |
For the second part of the problem, we can compute the projection of y onto the subspace spanned by u1 and u2 using the formula,
\(projwy\)= (y'u1/u1'u1)u1 + (y'u2/u2'u2)u2. Plugging in the given values, we get:
\(projwy\)= | 22/9 |

mateo has drawn a line to represent the parallel cross-section of the triangular prism. is he correct? explain. riangular prism lying on a rectangular face and a line drawn along the length of a rectangular face
Answers
Based on the information provided, Mateo has drawn a line to represent the parallel cross-section of the triangular prism. Is he correct? Yes, he is correct. Here's an explanation:
A triangular prism has two triangular bases and three rectangular faces. When a triangular prism is lying on a rectangular face, it means that one of its rectangular faces is on the bottom. If Mateo draws a line along the length of this rectangular face, he is creating a parallel cross-section of the triangular prism.
This is because the line he drew is parallel to the triangular base of the prism, and the two bases are also parallel to each other. A parallel cross-section is created when a plane cuts through a solid parallel to its base, and in this case, Mateo's line fulfills this condition.
Therefore, Mateo is correct in representing the parallel cross-section of the triangular prism by drawing a line along the length of a rectangular face.

How many elementary events are in the sample space of the experiment of rolling three fair coins? 2 9 8 6
Answers
When we roll three fair coins, there are two possible outcomes for each coin - either it lands heads up or tails up. There are 8 elementary events in the sample space of the experiment of rolling three fair coins.
The sample space of this experiment consists of all possible combinations of three outcomes, which can be calculated by multiplying the number of outcomes for each coin: 2 x 2 x 2 = 8.
Each of these combinations is called an elementary event, which means that there are 8 elementary events in the sample space of the experiment of rolling three fair coins. We can list them as follows:
1. HHH (all three coins land heads up)
2. HHT (two coins land heads up, one lands tails up)
3. HTH (two coins land heads up, one lands tails up)
4. THH (two coins land heads up, one lands tails up)

Given :
The Sugar Sweet Company will choose from two companies to transport its sugar to market.
The first company charges $3995 to rent trucks plus an additional fee of $225.75 for each ton of sugar.
The second company charges $5500 to rent trucks plus an additional fee of $150.50 for each ton of sugar.
To Find :
How, many tons of sugar will cost same in both companies.
Solution :
For company 1 :
P1 = (225.75)x + 3995
For company 2 :
P2 = (150.50)x + 5500
For same cost :
P1 = P2
(225.75)x + 3995 = (150.50)x + 5500
x( 225.75 - 150.50 ) = ( 5500- 3995)
x( 75.25 ) = 1505
x = 20
Therefore, 20 tons of sugar will cost same.
Hence, this is the required solution.

Answer:

aki ola In the figure below AB=24cm,BD=17cm,AD=13cm and ACD=90Degrees. find CD
Answers
The Length of CD is 27.875 cm.
We have,
AB=24 cm, BD= 17 cm, AD = 13 cm
and, ACD=90Degrees
Using Pythagoras theorem
AD² = AC² + CD²
13² = AC² + (x-17)²
169 = AC² + x² + 289 - 34x
- x² + 34x - 120 = AC²
AC² = (x-4)(x-30)
Again,
AB² = AC² + CB²
24² = (x-4)(x-30) + x²
576 = - x² + 34x - 120 + x²
34x = 696
x= 10.875
Thus, the length of CD is

If the sculpture was made of solid bronze, its weight could be approximated using the density of bronze , the volume, , in cubic meters, the mass, , in kilograms and applying the formula . Approximately, how many pounds would the sculpture weigh if it was made of solid bronze?
Answers
The weight of the spherical sculpture in pounds is approximately 251607 pounds
How to find the weight of the sculpture in pounds?
The sculpture is spherical and its made of solid bronze.
Therefore,
density = mass / volume
where
density = 7700 kg / m³
volume = 4 / 3πr³
volume = 4/ 3 × 3.14 × 1.524³
volume = 44.4574491494 / 3
volume = 14.8191497165 m³
Therefore,
mass = 7700 × 14.8191497165
mass = 114107.452817 kg
1 kg = 2.205 pounds
114107.452817 = ?
cross multiply
mass in pounds = 114107.452817 × 2.205
