x = 41 cm

Here is why:

For this question we have to use the pythagorean theorem, which is used for right triangles. The hypotenuse will always be the last in this theorem.

[tex]a^2+b^2=c^2[/tex]

Plug in.

[tex]9^2+40^2=c^2[/tex]

[tex]81+1,600=c^2[/tex]

Add together.

[tex]1,681=c^2[/tex]

Now we will find the square root of 1,681, since c is squared.

[tex]\sqrt{1,681}[/tex]

= 41 cm

57.8  and 32.2 degrees

Step-by-step explanation:

Complementary angles = 90 degrees

90-57.8= 32.2

Answer:

17.5

Step-by-step explanation:

11 +  24 = 35 /2

Answer:

17.5.

Step-by-step explanation:

The total number of integers from 11 to 24 =  13 + 1 = 14.

So the  2 middle numbers are 17 and 18.

Number in the middle = 17.5.

This is the median of the list of numbers.

Step-by-step explanation:

The solution to the system of linear equations represented by D and Dx is (x,y,z) = (5, 4, -11), which corresponds to option A.

To solve for Dx in the given system of linear equations, we multiply matrix D by the unknowns (x, y, z). So let's assume that Dx = (x, y, z).

By comparing the results of Dx and the given matrix, we can write the system of equations as:

By solving this system of equations, we can find that the solution is (x,y,z) = (5, 4, -11), which corresponds to the multiple-choice option A.

To find the solution of the system of linear equations represented by matrices D and Dx, we need to solve the equation Dx = Dⁿⁿ. By calculating the inverse of matrix D and substituting the values of Dx, we find that the solution is (5, 7, -9).

To find the solution of the system of linear equations represented by matrices D and Dx, we need to solve the equation Dx = Dⁿⁿ

Let's use matrix inversion to solve for x. We know that Dx = Dⁿⁿ can be rewritten as x = Dⁿⁿ −1 Dx. To find Dⁿⁿ −1, we need to calculate the inverse of matrix D:

After calculating the inverse of matrix D, we can substitute the values of Dx into the equation x = Dⁿⁿ −1 Dx to find the solution.

Plugging in the values of Dⁿⁿ and Dx, we get x = (5, 7, -9).

Answer:

Step-by-step explanation:

4 times

Each term of G is 4 times the corresponding terms of H.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

we have a table between G and H.

So, take two pair of G and H as (8, 2) and (16, 4).

Then, the slope

= (4 -2)/ (16- 8)

= 2 / 8

= 1/4

Thus, the G is 4 times the corresponding terms of H.

Answer:8picm3

Step-by-step explanation:

The probability of rolling a die and it landing on 4 while also drawing a heart from a deck of 52 cards is 1/24.

The experiment involves rolling a die and drawing a card from a deck. The probability of rolling a specific number, like a 4, on a fair six-sided die is 1/6 since there are six possible outcomes, each equally likely. When drawing a card from a standard 52-card deck, the probability of drawing a heart is 1/4, because there are four suits and each suit has the same number of cards (13).

To find the combined probability of both independent events occurring, we multiply their individual probabilities: (1/6) for rolling a four and (1/4) for drawing a heart, which equals (1/6) * (1/4) = 1/24. Therefore, the probability of the die landing on a 4 and drawing a heart is 1/24.

Answer:

b. 504

Step-by-step explanation:

In this case, we have to apply the permutation formula, since the order is important and it cannot be repeated. The formula is as follows:

nPr = n! / (n-r)!

From 0 to 9, there are 10 digits, but we must remember that the number 7 has already been used and cannot be repeated, therefore n = 9. And they are 4 digits but only 3 are needed, therefore r = 3.

Replacing:

9P3 = 9! / (9-3)!

nPr = 504

Therefore the answer is b.

Lateral area = 94.2 ft²

Step-by-step explanation:

The formula for lateral area of cylinder is given as;

A_l = 2πrh

Where;

r is radius

h is height

Now, we are told that the distance between the 2 circular bases is 6ft. Thus, the height is 6ft.

Diameter is given as 5ft.

We know that radius = diameter/2

Thus;radius;r = 5/2 = 2.5 ft

So, lateral area = 2πrh = 2π x 2.5 x 6 = 94.2 ft²

Lateral area = 94.2 ft²

20,349x100,947

Step-by-step explanation:

A ON EDGDE

The expression which represents the number of possible groups of students that can fill the 11 available slots is 20,349 · 100,947.

Given that:

A high school is hosting a blood drive.

The problem can be done by using the concept of combinations.

Total number of students in Mr. Bentley’s class = 21

Number of slots available for Mr. Bentley’s class = 5

The number of possible groups that 21 students who can fill 5 slots are ²¹C₅.

Total number of students in Mr. Curren’s class = 23

Number of slots available for Mr. Curren’s class = 6

The number of possible groups that 23 students who can fill 6 slots are ²³C₆.

The number of possible groups is:

N = (²¹C₅) (²³C₆)

   = [21! / (5!)(21-5)!] [23! / (6!)(23-6)!]

   = (20349) (100947)

Given,

The radius of the pie container (R) = 9 in

The radius of the pie (r) = 8 in

To find the difference of the circumference of the pie container and pie.

Formula

The circumference of a circle = 2πr

Now,

The circumference of the pie container = 2×π×9 = 18π in

The circumference of the pie = 2×π×8 = 16π in

Hence,

The difference = 18π-16π = 2π = 6.28 = 6.3 inches (approx)

Step-by-step explanation:

12*13+8*5

Answer:

$196

Step-by-step explanation:

First, you have to know how many total there are for each. In total, there are 13 books and 8 magazines. We also need to know how much all of these cost. So, you multiply 13 by 12 to find the total cost of the books. 13 books times 12 dollars each is $156. Now, we do the same for the magazines. 8 magazines times 5 dollars each is $40. To find how much she spent in all, you have to add the two numbers.

$156 plus $40 is $196.
