John has the greater total change in the amount of detergent in their bottle.

Given that, Brenda pours laundry detergent from a bottle into the cap and then into the washing machine.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Every time she fills the cap, the amount of detergent in the bottle changes by -0.26 L. She fills the cap 314 times in all.

Now, the volume of bottle =314×0.26

= 81.64

≈ 82 L

Every time he fills his cap, the amount of detergent in his bottle changes by -0.21 L. He fills his cap 256 times in all.

Here, the volume of bottle =256×0.21

= 53.76

≈ 54 L

Hence, John has the greater total change in the amount of detergent in their bottle.

twice of 1/8 = 2/8 = 1/4

Answer:

25%

Step-by-step explanation:

"twice" means two times.

"twice the value of 1/8" is

2 × 1/8

(to multiply a whole number times a fraction, multiply the big number × the top number)

2 × 1/ 8 is 2/8

2/8 is 1/4.

1/4 = .25 = 25%

Since the answer is a percent, change 1/4 to a decimal, .25, change the decimal to a percent.

Or you could change 1/4 to 25/100. Percent means "per hundred" 25/100 is 25%.

Answer:

y-10=   1/2(x-2) --- point slope form

Step-by-step explanation:

Point slope form is:

y- y1=m(x-x1)

y1= 10

m= y2-y1/x2-x1

y2= 6

x2= -10

x1= -2

Using point slope form and defining the variables using the given coordinates, the equation can be written.

Answer:

y-6 = -1/3(x-10)

Step-by-step explanation:

Let's use point slope form! The form of this is y-y1 = m(x-x1) where m is the slope.We have points to use, so let's find the slope.

The slope is rise over run, so we take the difference in y and divide it by the difference in x. This gives us [tex](10-6)/(-2-10)[/tex], which simplifies to -1/3. Now we plug in a point, say (-2, 10) for x1 and y1, and -1/3 for the slope, which gives us y-6 = -1/3(x-10)

Another way you could approach this is to plug in both the points to solve for m. Plug in both the y-values(10, 6) for y and y1 and both the x-values(-2, -10) for x and x1.

This gives us [tex]10-6 = m(-2-10)[/tex], which simplifies to [tex]4 = -12m[/tex]. Dividing both sides by -12 gives m = -1/3, which is the slope. Whichever way makes most sense works!

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Slope can be determined by using two points (x1, y1) and (x2, y2) and putting them in rise-over-run format (rise-over-run is equal to slope)

in this case we can use (3, 2) as (x1, y1) and (0, 0) as (x2, y2)

Rise-over-run format is: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

  C.  x² -8x +16 = 20

Step-by-step explanation:

You want the next step in completing the square after you get x² -8x = 4.

The constant in a perfect square monic trinomial is the square of half the coefficient of the linear term.

The coefficient of x is -8. Half that is -4, and its square is (-4)² = 16. This will be the value added to the equation in the second step.

  x² -8x +16 = 4 +16

  x² -8x +16 = 20

Additional comment

A monic polynomial has a leading coefficient of 1. We generally work with monic quadratics when completing the square. We do this by factoring the leading coefficient out of the variable terms.

The required answer choice is vertical translation 2 units up and vertical translation 4 units down.

What is translation?

In mathematics, a translation is the movement of a shape to the left or right and/or up or down. The translated shapes appear to be the same size as the original shape, and thus the shapes are congruent. They were simply shifted in one or more directions. There is no change in the shape because it is simply moved from one location to another.

The -2 indicates that you need to translate 2 units up, and the -4 indicates that you need to translate 4 units down.

As a result, the answer is vertical translation 2 units up and vertical translation 4 units down.

Answer:

The machine requires at least 9 hours and 45 minutes to complete the hole on schedule.

Step-by-step explanation:

To find this, you can use the formula provided in the previous response:

(required depth - current depth) / digging rate = hours of digging

Plugging in the values from the problem, you get:

(12.5 feet - 4.75 feet) / (3/5 feet per hour) = (7.75 feet) / (3/5 feet per hour)

This simplifies to:

(7.75 feet) / (3/5 feet per hour) = 15.5 hours

Then, to convert this number of hours to hours and minutes, you can divide by the number of minutes in an hour (60 minutes) and round up to the nearest whole number for the number of hours. The remainder will be the number of minutes:

15.5 hours / 60 minutes/hour = 0.258333... hours

Rounding up to the nearest whole number, you get:

0.258333... hours = 1 hour

The remainder is:

15.5 hours - 1 hour = 14.5 hours

14.5 hours / 60 minutes/hour = 0.241666... hours

Rounding up to the nearest whole number, you get:

0.241666... hours = 0 hours

The remainder is:

14.5 hours - 0 hours = 14.5 hours

14.5 hours / 60 minutes/hour = 0.241666... hours

Rounding up to the nearest whole number, you get:

0.241666... hours = 0 hours

The remainder is:

14.5 hours - 0 hours = 14.5 hours

14.5 hours * 60 minutes/hour = 870 minutes

Therefore, the machine requires at least 9 hours and 45 minutes to complete the hole on schedule.

Step-by-step explanation:

Answer:x>1

Step-by-step explanation:

Answer: If you are looking for Area, use the formula A=length x width

If you are looking for Perimeter, use the formula P= 2(length x width)

Step-by-step explanation:

So, the Area would be A=12x9 = 108 meters squared (you're multiplying 12 meters and 9 meters, which squares the unit)

and the Perimeter would be P= 2(12x9) = 216 meters

The function that has a graph that is parallel to the graph of 2x-y=6 is y = 2x - 8

From the question, we have the following parameters that can be used in our computation:

2x - y = 6

Subtract 2x from both sides of the equation

So, we have the following representation

-y = -2x + 6

Multiply both sides of the equation by -1

y = 2x - 6

Also, from the question;

We have the following points

The point is given as

Point = (3, -2) i.e.  (x, y) = (3, -2)

The equation of a line can be represented as

y = mx + c

Where

Slope = m

By comparing the equations, we have the following

m = 2

This means that the slope is 2

The slopes of parallel lines have the same values

This means that the slope of the other line is 2

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = 2

(x₁, y₁) = (3, -2)

So, we have

y = 2(x - 3) - 2

Open the brackets

y = 2x - 6 - 2

Evaluate the like terms

y = 2x - 8

Hence, the line has an equation of y = 2x - 8
