Answer 1

Answer:

2⅒

Step-by-step explanation:

0.1 = 1/10

2 ⅒

Answer 2

Answer:

2 1/10

Step-by-step explanation:

To convert the decimal 2.1 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

2.1 = 2.1

     --------    

         1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

= (2.1 × 10)

    (1 × 10)              = 21

                             ------

                               10

Now you have to simplify, 2 1/10.

Write 1/4 on the number line.

Answers

Answer:

Step-by-step explanation:

Answer:

We have to represent 1/4 in the number line .

So simply will first write it in Fraction form that is

So we have to represent it on number line .

1/4 we have to mark on the right side of number line because it is a positive number having no negative number . That is why we will mark it on the right side of the number line .

As we know the denominator is 4 so between every number we will keep four points distance.

After the zero the first point is number 1 and number 2 and number 3 and so on ...

The four points will consider number 1 , 2 , 3 , 4 and so on ...number after four points I have written 1 because there is the denominator 4 so we should keep 4 points distance in each number .

So , The number 1 we will mark and write the denominator 4

Explain what the algebraic solution of a system of two linear equations is and what that means in terms of the graphs of the equations of the system. Use AT LEAST 2 complete sentence in
your explanation. (3 points)

Answers

The two methods of solving for systems of linear equations algebraically are the methods of substitution and elimination.

The goal of the method of substitution is to reduce a system of two linear equations in two variables to a single equation in one
variable.

The key step in using method of elimination is to obtain opposite coefficients for one of the variables so that adding the two equations eliminates this variable.

Solving systems of linear equations by graphing involves sketching the lines representing the equations to determine whether the lines intersect at a point, which is the solution of the system.

graph the line that passes through the point (0, -3) and is perpendicular to another line whose slope is 2

Answers

Answer:

 y = -1/2x -3

Step-by-step explanation:

The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:

y = mx + b

where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...

 y = -1/2x -3

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.

How fast did Car A travel?

(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)

Enter your answer in the box.

Answers

Answer:

We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.

x/2.4 = 22 + y/4

Since y = x, then:

x/2.4 = 22 + x/4

Solving for x, we obtain:

x= 132 meters traveled by both cars

Therefore, Car A has a speed of 55 mph.

Step-by-step explanation:

A line passes through the points (0, 9) and (9, 19). What is its equation in slope-intercept form?

Answers

Answer:

y = 10/9x + 9

Step-by-step explanation:

To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).

Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Let (x1, y1) = (0, 9)

and (x2, y2) = (9, 19)

Substitute these values on the formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}[/tex]

Therefore, the slope (m ) = 10/9.

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b ). It is also the value of the y when x = 0.

One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.

Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9

Answers

Answer:

the answer is 21.8

Substitute the value of the variable into the equation and simplify.

If x is 1.9 then the equation turns into: 2(1.9+9) so

1.9+9 = 10.9. Then since it was parentheses it will go back to: 2(10.9). If any number is in parentheses and doesn’t have a plus or minus sign in-front of it, then you multiply, So 2 times 10.9= 21.8.

Thus, If x= 1.9, Then 2(x+9)= 21.8.

Answer:

Step-by-step explanation: Exponential depreciation formula :-

y = A(1 - r)^t, where y is the value of good after t years , r is rate of depreciation and A is the initial value.

Given : A= $20800  ; r=10.75%=0.1075  

The equation models this situation:

Then, the value of car after t=13 years :-

Hence, the value of car after 13 years = $4742.10

Teens today are just too busy to add another stressor to their lives. Lets take a look at twenty-four hours in the life of a typical teen. Allocate eight hours per day for sleep, eight hours for school (including getting ready and travel time), three hours for homework, two hours for activities such as sports or a part-time job, two hours for dinner and family time, and one hour for socializing. These activities take up all twenty-four hours leaving scarcely any time for volunteer work. Should students have to sacrifice their one hour of socializing per day, or sacrifice an hour of precious family time? These options just dont make sense as making more demands on teens packed schedules can have serious side effects. Teens who are too busy feel tired, anxious, or depressed. Studies show they often have headaches or stomachaches due to stress, missed meals, or lack of sleep and they may fall behind in school, causing their grades to suffer.
