Answer:

21/8

Step-by-step explanation:

3(7/8)=21/8

To multiply a whole number by a fraction, you have to change the whole number (the 3) into a fraction. To do this, simply put the 3 over 1.

3/1 x 7/8. Multiplying fractions is so easy because all you have to do is multiply the numerators together and then the denominators together.

3x7=21

1x8=8

21/8

This fraction cannot be reduced, but it can be rewritten as a mixed number.

21 divided by 8 is 2 with a remainder of 5.

The answer is 21/8 or 2 5/8. (they mean the same thing)

Final Answer:

The equation of the image after a dilation with a scale factor of 4, centered at the origin, is y = 8x + 8.

Explanation:

When a function undergoes dilation centered at the origin, each coordinate (x, y) is transformed to (kx, ky), where k is the scale factor. In this case, the original equation y = 2x + 2 is dilated by a factor of 4. Therefore, the new equation becomes y' = 4(2x + 2), which simplifies to y' = 8x + 8. The scale factor of 4 multiplies both the coefficient of x and the y-intercept, resulting in a steeper slope and a vertical shift.

In the original equation, the coefficient of x was 2, indicating a slope of 2. After the dilation, the coefficient becomes 8, indicating a steeper slope of 8. Additionally, the y-intercept of 2 is multiplied by 4, yielding a new y-intercept of 8. This transformation preserves the line's direction while magnifying its steepness and shifting it vertically. The equation y' = 8x + 8 represents the dilated image of the original line.

To summarize, the process involves multiplying both the coefficient of x and the y-intercept by the scale factor. This scaling maintains the line's direction while adjusting its steepness and vertical position. The resulting equation, y' = 8x + 8, accurately describes the image of the original line after dilation by a factor of 4 centered at the origin.

The total number of students actually went for skiing is 0.75 times the total students .

Step-by-step explanation:

Given as :

Some Students were surveyed about their wither break plans.

The percentage of students who actually did not go for skiing = 25 %

So , The percentage of students who actually go for skiing = 100 % of students - 25 %

I.e The percentage of students who actually go for skiing = 75 %

Let The total number of students = x

So, out of x students , The The percentage of students who actually go for skiing = 75 % of the total students

I.e The The percentage of students who actually go for skiing = 75 % of x

Step-by-step explanation:

You move the decimal point of a number until the new form is a number from 1 up to 10 (N), and then record the exponent (a) as the number of places the decimal point was moved. Whether the power of 10 is positive or negative depends on whether you move the decimal to the right or to the left. Moving the decimal to the right makes the exponent negative; moving it to the left gives you a positive exponent.

1, 5, 25, 125

r = 5 ÷ 1 = 25 ÷ 5 = 125 ÷ 25 = 5 ← geometric

4, 8, 16, 32

r = 8 ÷ 4 = 16 ÷ 8 = 32 ÷ 16 = 2 ← geometric

2, 6, 18, 54

r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 ← geometric

Answer:

3, 6, 9, 12 would not be a geometric sequence.

In Mathematics, if a six-digit code can have each digit repeat there are 10 options (0-9) for each position. Having six positions, we multiply the possibilities together, leading us to a conclusion of 1,000,000 possible codes.

The calculation of different codes for a house's security system is a problem of permutation and combination under the field of Mathematics. The code consists of six digits and each digit can be repeated, meaning that there are 10 possibilities (0-9) for each of the 6 positions in the code.

Therefore, for each of the six positions in the code, there are 10 possibilities. To determine the total number of possible codes, we would multiply the number of possibilities for each digit together: 10*10*10*10*10*10 = 1,000,000. So, there are one million possible combinations for the 6-digit code.

Answer:

1)  x =  15, y =  30 is the solution of the given system of equation.

2) x = 0.5 , y = 12.5   is the solution of the given system of equation.

Step-by-step explanation:

First QUESTION:

Here the given set if equation are:

y =  x + 15

y = 2 x

Substituting the value of y = 2 x in the first equation, we get:

y =  x + 15  ⇒   2 x = x + 15

or, 2 x - x = 15

⇒ x  = 15

⇒ y = 2 x  = 2 (  15) =  30, or y = 30

Hence, x =  15, y =  30 is the SOLUTION of the given system of equation.

Second QUESTION:

Here the given set if equation are:

y  = x +12

4 x + 2 y = 27​

Substituting the value of y = x + 12 in the second  equation, we get:

4 x + 2 y = 27​   ⇒ 4 x + 2 (x + 12)  = 27​

or, 4 x + 2(x) + 2 (12) = 27

⇒ 6 x  = 27 - 24 = 3

⇒ x = 3 /6  = 0.5

Now, y = x +  12  = 0.5 +  12 = 12.5 or y = 12.5

Hence, x = 0.5 , y = 12.5  is the SOLUTION of the given system of equation.

Step-by-step explanation:

Answer:

(a) 65 gallons per minute

(b) 280 gallons

(c) 8080 gallons

(d) 150 minutes.

Step-by-step explanation:

Water is filled up by pumps into a tank at a constant rate.

The volume of water in the tank V, in gallons, is given by the equation  

V(t) = 65t + 280 ......... (1), where t is the time, in minutes.  

(a) The rate at which water is pumped into the tank is 65 gallons per minute. (Answer)

(b) 280 gallons of water was there in the tank when the pumps were turned on because f(0) = 65 × 0 + 280 = 280. (Answer)

(c) After 2 hours i.e. (2 × 60) = 120 minutes the volume of water in the tank will be f(120) = 65 × 120 + 280 = 8080 gallons. (Answer)

(d) The tank has a capacity of 10000 gallons of water.

So, if the tank starts to overflow after t minutes, then  

10000 = 65t + 280

⇒ 65t = 9720

⇒ t = 149.53 minutes ≈ 150 minutes (Answer)

Final answer:

The rate at which water is being pumped into the tank is 65 gallons per minute, the tank initially had 280 gallons of water, after two hours the volume will be 8,080 gallons, and the pumps will turn off after approximately 150 minutes when the volume reaches 10,000 gallons.

Explanation:

The water tank problem can be analyzed step by step based on the given linear equation v(t) = 65t + 280, which describes the volume V of water in gallons as a function of time t in minutes.

(a) Rate of Water Being Pumped

The coefficient of t in the equation represents the rate at which water is being pumped into the tank. Therefore, the water is being pumped at a constant rate of 65 gallons per minute.

(b) Initial Volume of Water

The constant term in the equation, 280, represents the volume of water that was in the tank when the pumps were turned on. This means the tank initially had 280 gallons of water.

(c) Volume After Two Hours

To convert two hours to minutes, we multiply by 60 minutes per hour, giving us 120 minutes. Plugging this value into the equation gives us v(120) = 65(120) + 280 = 7,800 + 280 = 8,080 gallons. So, after two hours, the volume of water in the tank would be 8,080 gallons.

(d) Time to Reach 10,000 Gallons

To find the time when the volume reaches 10,000 gallons, we set the equation equal to 10,000 and solve for t: 10,000 = 65t + 280. Subtracting 280 from both sides gives us 9,720 = 65t, and dividing both sides by 65 gives us t ≈ 149.54 minutes. To the nearest minute, the pumps will turn off after approximately 150 minutes.

Step-by-step explanation:

The pair (1,2) is a solution to the inequality 6x - y > 3 because when these values are substituted into the inequality, the result is 4 > 3, which is a true statement.

The question is asking if the pair of numbers (1,2) is a solution to the inequality 6x - y > 3. We can evaluate this by substituting the pair of values (1, 2) into the inequality in place of x and y. This gives us 6*1 - 2 > 3, or 6 - 2 > 3, which simplifies to 4 > 3. Since 4 is indeed greater than 3, we can conclude that the pair (1,2) is a solution to the inequality 6x - y > 3.

Answer:

Part a) [tex]x+y < 400[/tex]

Part b) The graph in the attached figure

Part c) see the explanation

Part d) The number of seat tickets sold must be less than 300 tickets

Step-by-step explanation:

Part a) write an inequality to describe the constraints. specify what each variable represents

Let

x ----> number of lawn tickets sold

y ----> number of seat tickets sold

we know that

The sum of the number of lawn tickets sold plus the  number of seat tickets sold must be less than 400 tickets

so

The linear inequality that represent this situation is

[tex]x+y < 400[/tex]

Part b) use graphing technology to graph the inequality. sketch the region on the coordinate plane

we have

[tex]x+y < 400[/tex]

using a graphing tool

The solution is the triangular shaded area of positive integers (whole numbers) of x and y

see the attached figure

Remember that the values of x and y cannot be a negative number

Part c) name one solution to the inequality and explain what it represents in that situation

we know that

If a ordered pair lie on the solution of the inequality, then the ordered pair is a solution of the inequality (the ordered pair must satisfy the inequality)

I take the point (200,100)

The point (200,100) lie on the triangular shaded area of the solution

Verify

Substitute the value of x and the value of y in the inequality and compare the result

For x=200,y=100

[tex]x+y < 400[/tex]

[tex]200+100 < 400[/tex]

[tex]300 < 400[/tex] --> is true

so

The ordered pair satisfy the inequality

therefore

The ordered pair is a solution of the inequality

That means ----> The number of lawn tickets sold was 200 and the number of seat tickets sold was 100

Part d) if you know that exactly 100 lawn tickets were sold, what can you say about the number of seat tickets?

we have that

x=100

substitute in the inequality

[tex]100+y < 400[/tex]

solve for y

subtract 100 both sides

[tex]y < 400-100[/tex]

[tex]y < 300[/tex]

therefore

The number of seat tickets sold must be less than 300 tickets

Final answer:

The horizontal asymptote indicates that as more pure acid is added, the concentration approaches 1, meaning the acid concentration trends towards 100% purity but never fully reaches it. (Option D)

Explanation:

The horizontal asymptote of the function f(x) = x + 60 / (x + 300) describes the behavior of the acid concentration as the volume of pure acid x becomes very large. When an increasingly larger volume of pure acid is added, the concentration of the acid in the new substance approaches a certain value. This implies that, no matter how much more acid is added past a certain point, the concentration doesn't change significantly.

The correct statement regarding the horizontal asymptote is: D. As more pure acid is added, the concentration of acid approaches 1. This means that the concentration of the acid will get closer and closer to 100%, or pure acid, but it will never actually reach that concentration because you are always adding the acid to some amount of solution.

The possible transformations that establish congruence between shapes are dilation, translation, and reflection.

The possible rules that represent a transformation mapping one shape onto another to establish congruence are:

A dilation by a scale factor of 3 about the origin stretches or shrinks the shape uniformly in all directions. A translation moves the shape without changing its size or shape. A reflection across a line is a flip of the shape over that line. These transformations can establish congruence between shapes.

Transformations that establish congruence between shapes by preserving size, shape, and orientation ensure that the transformed shape aligns with the original shape. The correct answer is option

B) A translation to the right 2 and down 6.

C) A reflection across the line y=2.

D) A counter-closckwise rotation of 90 degrees about the origin.

The rules that represent transformations mapping one shape onto another to establish congruence are:

B) A translation to the right 2 and down 6, which preserves both size and shape, simply moving the shape to a different location without changing its orientation or proportions.

C) A reflection across the line y=2, which reflects the shape across a line, maintaining its size and shape but reversing its orientation.

D) A counter-clockwise rotation of 90 degrees about the origin, which rotates the shape by a right angle, preserving its size and shape while changing its orientation.

These transformations preserve congruence by maintaining the size, shape, and orientation of the original shape.

Options B, C, and D represent transformations that map one shape onto another to establish their congruence, preserving size, shape, and orientation.
