Answer:

C) 21

Explanation:

The middle column represents the tens place, while the column on the left is the ones place. Range is the difference between the highest number and the lowest number.

The lowest number for road A is 29, the 2 from the middle column and 9 from the left. The largest number is 50, the 5 from the middle column and 0 from the left column.

50 - 29 = 21

Answer:

Step-by-step explanation:

the adjacent angles are congruent

angle 1 = 51°

the sum of the angles is 360°

51 · 2 + 2 · angle (2) = 360

102 + 2angle(2) = 360

2angle (2) = 360 - 102

2 angle (2) = 258

angle (2) = 258/2

angle (2) = 129°

angle (3) = 129°

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

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:

  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:

2x+y=-4

Step-by-step explanation:

y-2=-2(x+3) is in point-slope form.

Ax+By=C is standard form.

We have to bring x and y to the same side of the equation.

First, let's distribute.

y-2=-2(x)-2(3)

y-2=-2x-6

Next, we will add 2 to both sides to get rid of the -2 on the left side of the equation.

y=-2x-6+2

Then, we will add 2x to both sides to get rid of the -2x on the right side of the equation.

2x+y=-6+2

Now x and y are on the same side of the equation. We just need to simplify the right side.

2x+y=-4

This is the answer in standard form.

Answer:

2x + y = -4

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Standard form of a linear equation}\\\\$Ax+By=C$\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are constants. \\ \phantom{ww}$\bullet$ $A$ must be positive.\\\end{minipage}}[/tex]

Given equation:

[tex]y-2=-2(x+3)[/tex]

To write the given equation in standard form, collect the terms with variables on the one side of the equation (ensuring the term in x is positive), and collect the constants on the other side of the equation.

Distribute the right side of the equation:

[tex]\implies y-2=-2 \cdot x+(-2) \cdot 3[/tex]

[tex]\implies y-2=-2x-6[/tex]

Add 2x to both sides of the equation:

[tex]\implies y-2+2x=-2x-6+2x[/tex]

[tex]\implies y-2+2x=-6[/tex]

Add 2 to both sides of the equation:

[tex]\implies y-2+2x+2=-6+2[/tex]

[tex]\implies y+2x=-4[/tex]

Rearrange the left side to standard form:

[tex]\implies 2x+y=-4[/tex]

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.

Answer:

y=1/2x-2

Step-by-step explanation:

It should be noted that 23.4 is 8.1 percent of 288.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

23.4 is what percent of 288 will be calculated thus:
