Answer: -16

Step-by-step explanation:

Let the number be y

Four times a number minus twenty-one can be written as:

(4 × y) - 21 = 4y - 21

Six times the number plus eleven can be written as:

(6 × y) + 11 = 6y + 11

Combining both equations will give:

4y - 21 = 6y + 11

4y - 6y = 11 + 21

-2y = 32

y = 32/-2

y = -16

The number is -16

Answer:

(5/3,5)

Step-by-step explanation:

The solution to the system of equations y = 13x - 1 and y = 5 is (6/13, 5).

To find the solution to the system of equations y = 13x - 1 and y = 5, we can substitute the second equation directly into the first one. Since both equations equal y, they must equal each other, thus:

13x - 1 = 5.

We can then solve for x:

Add 1 to both sides: 13x = 6

Divide both sides by 13: x = 6/13

Having determined the value of x to be 6/13, we can substitute this back into either equation to find y. Using the simpler one, y = 5.

Thus, the solution to the system of equations is (6/13, 5).

Answer:

$1,467.20

Step-by-step explanation:

Adjusted monthly income is the gross income minus any payments made every month. 5600 - 360 = 5240. To get 28% of her adjusted income multiply 5240 X.28 =1467.20

To calculate 28% of $5600, multiply 5600 by 0.28. The result is $1568, which is 28% of Adeva's gross monthly income.

The issue is figuring out 28% of Adeeva's gross monthly salary, which is fixed at $5600. The calculation is simple to perform using the (Amount/Total) x 100 rule for percentage calculations. The decimal equivalent of 28% is 0.28, so multiply $5600 by that number to get 28%. The computation yields a value of $1568. Therefore, $1568 or 28% of Adeeva's gross monthly revenue. By analyzing particular sections of overall profits, this technique demonstrates a fundamental use of percentages, enabling accurate financial computations and planning.

Answer:

"female" and "pass" = 0.7368

"female" and "fail" = 0.2632

"male" and "pass" = 0..7368

"male" and "fail" = 0.2632

Step-by-step explanation:

To find the values for the row relative frequency, we just need to divide each value of the first table by the sum of the values of its respective row.

So, we will have that:

Relative value for "female" and "pass": 42 / (42 + 15) = 0.7368

Relative value for "female" and "fail": 15 / (42 + 15) = 0.2632

Relative value for "male" and "pass": 14 / (14 + 5) = 0..7368

Relative value for "male" and "fail": 5 / (14 + 5) = 0.2632

The two-way table of row relative frequencies should be completed as follows;

               Pass       Fail       Row total

Female    0.74       0.26        1.00

Male        0.74       0.26        1.00

In order to determine each of the values for the row relative frequency, we would have to divide each value in the column by the sum of the values in the corresponding row of the two-way frequency table;

Relative frequency for "female" and "pass" is given by:

42/(42 + 15) = 0.7368 ≈ 0.74.

Relative frequency for "female" and "fail" is given by:

15/(42 + 15) = 0.2632 ≈ 0.26.

Relative frequency for "male" and "pass" is given by:

14/(14 + 5) = 0.7368 ≈ 0.74.

Relative frequency for "male" and "fail" is given by:

5/(14 + 5) = ≈ 0.26.

0.74 + 0.26 = 1.00

Answer: The length of the side of a square is 20 cm.

Step-by-step explanation:

Part 1: Find the x

First, you know that all sides of a square are equal, therefore, these two equations should be equal.

6x - 1 = 4x+6

Now, you simplify.

You would move whichever like term you want (either 6x over to the side of 4x (or vice versa) or -1 to the side of the 6 (or vice versa)

In my case, I will move 4x over to the other side.

Now I have:

6x - 4x -1 = 6

You can subtract like terms, in this case 6x and 4x:

2x - 1 = 6

Now you do the same, just with the constant numbers.

You would move over the -1 to try isolate the variable. (Keep in mind that the sign (positive or negative) changes when you move it to the other side.

2x = 6 +1

2x = 7

Then, you want to leave x by itself, so you have to divided 2x by 2. What you do to that side, you have to do to the other side.

2x/2 = 7/2

x = 3.5

Part 2: Plugging x into the equation

Now, since you have to x, you have to put it in any of the equations. Keep on mind it doesn’t matter, since both sides are the same anyway.

I‘m going to use the side 6x -1.

You now have to subsitute 3.5 for the x.

You now have:

= 6 (3.5) -1

= 21 -1

= 20

Therefore, your side is equal to 20 cm.

The answer is D. x2 + 6x + 9 i just took the assignment

Final answer:

The expression that represents the area of a square plaza with side length 2x + 3 is x^2 + 6x + 9.

Explanation:

The question is asking to determine the expression that represents the area of a square plaza. The formula to calculate the area of a square is the length of one side squared (s2). If the side length is represented by the expression 2x + 3, then the area will be (2x + 3)2. When this binomial is squared, it follows the formula (a + b)2 = a2 + 2ab + b2, which leads to (2x)2 + 2(2x)(3) + (3)2 = 4x2 + 12x + 9. So, the correct expression representing the area of the plaza is x2 + 6x + 9.

Answer:

The volume of the hemisphere with a radius of 9 centimeters is 1526.8 cubic centimeters.

To find the volume of the hemisphere with a radius of 9 centimeters, we use the formula for the volume of a sphere and then divide it by 2, because a hemisphere is half of a sphere. The volume V of a sphere is given by V = (4/3)πr³, where r is the radius.

Therefore, the volume of the hemisphere is V = ½ × (4/3)πr³. Plugging in the given radius:

V_hemisphere = ½ × (4/3)π × (9 cm)³

V_hemisphere = ½ × (4/3) × 3.1416 × 729 cm³

V_hemisphere = ½ × (4× 3.1416 × 243)

V_hemisphere = ½ × 3053.6288 cm³

V_hemisphere = 1526.8144 cm³

When rounded to the nearest tenth, the volume of the hemisphere is 1526.8 cm³.

Answer:

The probability of choosing tiles which sum is 12 is 1/21

Step-by-step explanation:

The numbers we have is 1.2,3,4,5,6 and 7

The sum we are looking at is 12. The only sum that can give us this sum is the addition of 7 and 5

There are only two ways we can make this selection if order matters.

Either we pick 5 first then 7 second or 7 first and 5 second

The probability of picking a 5 first will be 1/7, since it is without replacement , the probability of picking a 7 next will be 1/6

The joint probability here would thus be 1/7 * 1/6 = 1/42

In the other second case where we are picking a 7 first and a 5 second, the probability here will be the same as first just that we reversed the other. Hence, the probability here is also 1/42

Now, the probability of either of the two orders happening will be 1/42 + 1/42 = 2/42 = 1/21

Final answer:

The probability of choosing tiles whose sum is 12 is 1/49.

Explanation:

Probability of choosing tiles whose sum is 12:

Number of favorable outcomes: 1 (getting two tiles that sum up to 12, which is 6+6)Total number of possible outcomes: 7*7 = 49 (as there are 7 choices for each tile)Probability = Number of favorable outcomes / Total number of possible outcomes = 1/49

We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.

We will use volume of cone formula to solve our given problem.

[tex]V=\frac{1}{3}\pi r^2 h[/tex], where

r = Radius of cone,

h = Height of cone.

We know that diameter is two times the radius, so radius will be half of diameter that is [tex]r=\frac{7}{2}[/tex].

[tex]V=\frac{1}{3}\pi\cdot (\frac{7}{2})^2\cdot 10[/tex]

[tex]V=\frac{1}{3}\pi\cdot (\frac{49}{4})\cdot 10[/tex]

[tex]V=128.2817[/tex]

[tex]V\approx 128.3[/tex]

Therefore, the volume of the cone would be approximately 128.3 cubic cm.

Answer: Option C.

Step-by-step explanation:

We have functions of r(θ)

In our graph, we can see that the minimum value of r is when θ = 0°, and the maximum value is when θ = 180°.

We also know that the graph is in the square (-5, 5)x(-5, 5) and you can see that the maximum radius is almost less than 5.

Then let's analyze the options:

A) r = 3 - 2*cos(θ)

the maximum is at the right angle, but the maximum is:

r = 3 -2*(-1) = 5, so this maximum value is bigger than the one in the graph.

B) r = 3 - sin(θ)

For the sin functions, the maximum and minimum do not correspond with the values i write earlier, so we can discard this option.

C) r = 3 - cos(θ)

The maximum is: r = 3 - (-1) = 4, so this may be the correct answer.

the minimum is r = 3 - 1 = 2,

this is a possible equation for our circle.

D) r = 2 - 2*cos(θ)

Here, when θ = 0, we have: r = 2 - 2*1 = 0, but in the graph we can see that the radius is not 0 when θ = 0, so we can discard this option.

So the only option that makes sense is option C.

Answer:

Step-by-step explanation:

Let the first number be x

Given second number is 6 times a first number.

If first number is x then second number is 6*x = 6x

Given third number is 100 more than  the first number

If first number is x then third number is x+100 = x+100

Sum of these three numbers in terms of x

is

sum = x+ 6x+x+100 = 8x+100 __________1

Given, that sum of these numbers is 812.

equating 812 with equation 1 we have,

8x+100  = 812

=> 8x = 812- 100

=> 8x = 712

=> x = 712/8 =  89.

Therefore,

first number = x = 89

second number = 6x = 89*6= 534

third number = x+100 = 89+100 = 189

The three numbers in the problem are 89, 534, and 189. We found these by defining the first number as x, creating equations based on the given relationships, and solving for x.

Let's define the first number as x. According to the problem, the second number would be 6x (as it is 6 times the first number), and the third number would be x + 100 (as it is 100 more than the first number). The sum of these three numbers is given as 812. So, we can set up the equation:

x + 6x + (x + 100) = 812

Combine like terms to simplify the equation:

8x + 100 = 812

Subtract 100 from both sides of the equation:

8x = 712

Divide both sides by 8 to find the value of x:

x = 89

Now that we have the value of the first number, we can find the other two numbers:

The second number is 6 times 89, which is 534.

The third number is 89 + 100, which is 189.

Therefore, the three numbers are 89, 534, and 189.
