write some numbers that are equal to 15÷12

Answer:

the slope is 1

Step-by-step explanation:

Answer:

The slope is -1/2

Step-by-step explanation:

x + 2y=4

Lets get the equation in the form y= mx+b

where m is the slope and b is the y intercept.

x + 2y=4

Subtract x from each side

x-x+2y = -x+4

2y = -x+4

Divide each side by 2

2y/2 = -1/2 x +4/2

y = -1/2x +2

The slope is -1/2

Answer:

    Statement 3 as well as statement 1 are true

Step-by-step explanation:

Answer:

1.function 1 has a greater rate of change than function 2

3. Function 1 has a greater y-intercept than function 2

Step-by-step explanation:

Using the table we can find the slope using

m = (y2-y1)/ (x2-x1)

m = (29-5)/ (8-0)

     = 24/8

    = 3

The rate of change for the table is 3

The y intercept is (0,5)  

Using the graph  (0,-1)  and (2,0)

m = (y2-y1)/ (x2-x1)

m = (0--1)/ (2-0)

     = (0+1)/2

    = 1/2

The y intercept is (0,-1)

Since 3>1/2 , function 1 has a greater rate of change than function 2

Since 5>-1, function 1 has a greater y-intercept than function 2

To find the volume of a rectangular prism, multiply the length, width, and height. The formula is V = l * w * h.

To find the volume of a rectangular prism, you need to multiply the length, width, and height of the prism.

The formula for the volume of a rectangular prism is: V = l * w * h.

So, to find the volume of a rectangular prism, you need to know the measurements of its length (l), width (w), and height (h) in the same unit of measurement.

Multiply these values together to find the volume in cubic units (such as cubic centimeters or cubic meters).

For example, if a rectangular prism has a length of 5 centimeters, a width of 3 centimeters, and a height of 2 centimeters, you would calculate the volume as follows: V = 5 cm * 3 cm * 2 cm = 30 cm³.

The volume of the rectangular prism, obtained from the product of the known face area and the width is 11 2/3 cube units

Volume = 11 2/3 units³

The details of the steps used to find the volume of the prism can be presented as follows;

The dimensions of the rectangular prism includes a face area and the width of the prism

Area of a face of the rectangle = 3 1/3 square units

Width of the rectangular prism = 1 2/5 units

Area of a rectangular prism = Length × Width × Height

The length and the height of the rectangular prism form the face with the known area of 3 1/3 square units

Therefore; Area of a rectangular prism = Width × Area of the vertical face perpendicular to the width of the rectangular prism

Area of a rectangular prism = 1 2/5 units × 3 1/3 square units

1 2/5 units × 3 1/3 square units = (7/2) × (10/3)

(7/2) × (10/3) = 70/6

70/6 = 11 2/3

Area of the rectangular prism is 11 2/3 units³

Answer:

144

Step-by-step explanation:

Perfect square formula: a^2 - 2ab + b^2 (because that equals (a-b)^2)

x^2-2*12x+c

a = 1

b = 12

12^2 = 144

Answer:

The value of [tex]c =144[/tex] makes [tex]x^{2}-24x+c[/tex] perfect square.

Step-by-step explanation:

We have to make [tex]x^{2}-24x+c[/tex]

Since, Perfect square formula: [tex]a^{2} - 2ab + b^{2}=(a-b)^{2}[/tex]

Re-write [tex]x^{2}-24x+c[/tex] as,

[tex]x^{2}-2\times 12x+c[/tex]

Compare above with [tex]a^{2} - 2ab + b^{2}[/tex]

Where a = x  and b= 12

so, [tex]b=12[/tex]

⇒ [tex]c =12^{2}=144[/tex]

Hence, [tex](a-b)^{2}=(x-12)^{2}[/tex]

Therefore, the value of [tex]c =144[/tex] makes [tex]x^{2}-24x+c[/tex] perfect square.

Step by Step Explanation:

16. x - 4 = 4

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 4 (+4)

x = 4 + 4

x = 8

17. a/4 = 4

Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:

(a/4)(4) = (4)(4)

a = (4)(4)

a = 16

18. y * 20 = 30

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.

(y *20)/20 = (30)/20

y = 30/20

y = 3/2 or 1.5

19. x/5 = 20

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides

(x/5)(5) = (20)(5)

x = (20)(5)

x = 100

Answer:

(B) Revenue account which increases

Step-by-step explanation:

Hello, my dear friend, I am sure the question you are intending should be corrected as follows:

In transaction (C) on 5/10, the Fees Earned account is a(n) A. Expense account, which increases B. Revenue account, which increases C. Revenue account, which decreases D. Asset account, which decreases

If that is the case, then please note that whatever amount you earn, is an amount that will always increase. If you have no earnings, then nothing decreases nor decreases.

The Fees Earned account is a type of revenue account that increases when the company earns more fees. Therefore, option B (revenue account, which increases) is correct.

In transaction (C) on 5/10, the Fees Earned account is usually classified as a revenue account. Therefore, when a company earns fees, it records the transaction as an increase in the fees earned account. The more fees the company earns, the higher the balance in this account, representing the income the company has made. So, if the Fees Earned account is increasing in value, it would be correct to say that it is a revenue account, which increases. This makes option B the correct answer.

Answer:

Step-by-step explanation

You must find the common denominator for all of them.  

A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.

B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.

C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.

D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.

Answer: z < 4

z+4 > 2z

z+4-z > 2z-z ..... Subtract z from both sides

4 > z

z < 4

So the solution set for z is any number that is less than 4, which could be something like z = 2 or z = 3.

Answer:

Well, since they are lined up correctly already, you can combine the like terms and get 4x + 3y = 2.

Is that all you wanted?

Answer:

A) 3x - y = -5

B) x + 4y = 7

Whenever you have to solve for 2 unknowns, you need 2 equations.  (These are called solving simultaneous equations.)

Perhaps the easiest way to solve these is by the elimination of variables.

Looking at Equation A) we see that if we multiply it by 4, and add it to equation B), the "y" variable will be eliminated.

Multiplying equation A) by 4 we get

A) 12x - 4y = -20   then adding this to B)

B) x + 4y = 7   we get

EDITD TO CORRECT**************************************************

13x = -13

x = -13 / 13= -1

Then we can get x = -1 and insert it into either equation.  (Let's choose B)

B) -1 + 4y = 7

B) 4y = 8

y = 2

*******************************************************************************************

For a double-check we can insert x = -1 and y = 2 into either equation.  (Let's choose equation B)

B)  -1 + 4 * 2 = 7

B)  -1 + 8 = 7

And since -1 + 8 DOES equal 7, we know that we have solved for "x" and "y" correctly!

Answer:

D. -27+15 (N-1)

Step-by-step explanation:

-27, -12, 3, 18

Take the second term and subtract the first term to find the common difference

-12 - (-27)

-12+27 = 15

The common difference is +15

We are adding 15 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

an = -27 +15(n-1)

The correct nth-term expression for the given sequence is -27 + 15(n - 1), reflecting the sequence's consistent increase of 15 between terms.  So the correct option is D.

The student's question asks for the expression that defines the nth term of the sequence -27, -12, 3, 18, ... given that a1 = -27. Observing the sequence, we can see that each term increases by 15 from the preceding term. Thus, to find the nth term, we start with the first term (-27) and add 15 to it n times (n - 1), because the first term is already included.

The correct expression for the nth term is therefore -27 + 15(n - 1), which simplifies to -27 + 15n - 15 and further simplifies to -42 + 15n. This corresponds to option D: -27 + 15 (n - 1).

Answer:

the answer is 9.9

Step-by-step explanation:

12.1-2.2=9.9

The elevation of Tammy’s house is greater than the elevation of the ocean’s surface at 2 p.m. will be 9.9.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, on Tuesday at 2 p.m., the ocean’s surface at the beach was at an elevation of 2.2 feet. Winston’s house is at an elevation of 12.1 feet. The elevation of his friend Tammy’s house is 3 1/2 times the elevation of Winston’s house.

We have to find the elevation of Tammy’s house greater than the elevation of the ocean’s surface at 2 p.m.

Suppose the greater is the elevation of Tammy’s house than the elevation of the ocean’s surface at 2 p.m be x,

x=12.1-2.2

x=9.9

Thus, the elevation of Tammy’s house is greater than the elevation of the ocean’s surface at 2 p.m. will be 9.9.

Answer:

Side EH

Step-by-step explanation:

Side AD is proportional to side EH. If you look at ABCD, and compare it to EFGH, the ends of the name, AD, correspond with the ends of the other, EH.

Side AD of trapezoid ABCD is proportional to side EH of trapezoid EFGH due to the properties of similar geometric figures, where corresponding sides of similar shapes are in proportion.

The question asks which side of trapezoid EFGH is proportional to side AD of trapezoid ABCD, given that the two trapezoids are similar. In similar figures, corresponding sides are proportional. Therefore, if side AD of trapezoid ABCD corresponds to side EH of trapezoid EFGH, then these sides are proportional to each other.

Since we are discussing proportions and similarity of shapes, particularly trapezoids, we can reference several mathematical concepts. By the AAA theorem, which stands for angle-angle-angle, we know that if two or more corresponding angles in two figures are equal, then the figures are similar and the sides opposite these angles are proportional. Also, the proportions of corresponding sides can be determined using theorems regarding triangles and trapezoids.

We conclude that side AD is proportional to side EH because of the properties of similar geometric figures.

Answer:

A) 50%; This percentage is lower than expected in a normal distribution.

Step-by-step explanation:

Data points given:

55, 54, 66, 38, 53, 56, 57, 66, 45, 65

n = 10

The mean for the data points:

[tex] \frac{55+54+66+38+53+56+57+66+45+65}{10} [/tex]

Mean = 55.5

Standard deviation of data points:

[tex] = \sqrt{\frac{55-55.5)^2+(54-55.5)^2+(66+55.5)^2+(38-55.5)^2+(53-55.5)^2+(56-55.5)^2+(57-55.5)^2+(66-55.5)^2+(45-55)^2+(65-55)^2}{10}} [/tex]

= 8.59

Now let's find the data points that lie between 64.09 i.e (55.5 + 8.59) and 46.91 i.e (55.5-8.59)

We can see that 5 data points lie between 64.09 and 46.91 which are { 55,54,53,56,57}

The correct option is A, which states that 50% percentage is lowee than expected.

Step-by-step explanation:

The 3 foot stick broken in a 5:7 ratio results in two pieces measuring 1.25 feet and 1.75 feet, respectively.

The question involves a 3 foot stick that is broken into two pieces with a ratio of 5:7.

To find the lengths of the two pieces, we first add the parts of the ratio together, which gives us 12 parts in total.

Since the whole stick is 3 feet long, each part of the ratio represents \(\frac{3 feet}{12 parts}\) or \(\frac{1}{4} foot\) per part.

Thus, the length of the smaller piece is 5 parts (\(5 \times \frac{1}{4} = \frac{5}{4} feet\) or 1.25 feet) and the length of the larger piece is 7 parts (\(7 \times \frac{1}{4} = \frac{7}{4} feet\) or 1.75 feet).
