Answer:

A. 7.2 centimeters

Step-by-step explanation:

The length of the base is 7.2 centimeters. The area of a rectangle is length*width

The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.

The working is as follows :

Area = 90 cm²

Height = 12.5 cm

Length = ?

Length = Area ÷ Height

= 90 ÷ 12.5

= 7.2cm

The length of the base of the rectangle is found by dividing the area by the height, which gives 7.2 centimeters.

The subject is about finding the length of the base of a rectangle given its area and height. The formula to find the area of a rectangle is Area = Length x Width. From the question, we know the Area is 90 square centimeters and the height (which can also be considered as the Width) is 12.5 centimeters. Therefore, we can arrange the formula to solve for Length: Length = Area / Width.

Substituting the given numerical values we find: Length = 90 / 12.5 = 7.2 centimeters. So, the correct answer is 7.2 centimeters (Option A).

Answer:

C. x = 3

Step-by-step explanation:

8x - 12 = 4x

+12        + 12

8x = 4x + 12

-4x   -4x

4x = 12

----   ---

4     4

x = 3

C. x = 3

8x-12= 4x

move -12 to the other side

sign changes from -12 to +12

8x-12+12= 4x+12

8x=4x+12

move 4x to the other side.

sign changes from +4x to -4x

8x-4x= 4x-4x+12

8x-4x= 12

4x=12

divide both sides by 4 to get x by itself

4x/4= 12/4

Answer:

A graph has month on the x-axis and saved (money) on the y-axis. Points are at (0, 3,000), (2, 2,450), and (5, 1,625).

The instructor’s friend also plans to rent an apartment in the same complex. Use the graph to identify the y-intercept and the slope used to write the equation in slope intercept form.

y-intercept =

✔ 3000

Slope =

✔ –275

Linear equation =

✔ y = -275x + 3000

Step-by-step explanation:

The linear equation which models the data represented by the graph written is slope - intercept form is :y= - 275x + 3000

General form of a slope - intercept equation :

Slope = Rise / Run

The slope, b:

Slope = (1375 ÷ -5) = - 275

The intercept, c:

This is the point on the graph where the trend line crosses the y-axis.

Answer:

The shares were worth $8800, when they were originally purchased.

Step-by-step explanation:

After several shares of the company's stock were sold, a profit of $1,320 was earned.

The profit was 15% over a 30 day period.

Let the original price of the shares be = x

As there was a profit of 15% on x.

We get the following expression;

[tex]0.15x=1320[/tex]

Then x = 8800

Hence, the shares were worth $8800, when they were originally purchased.

Answer:

     x =13/16

Step-by-step explanation:

2(4-8x)+6=1

2*(4-8x) + 2*3 =1

2 ( 4 - 8x + 3 ) = 1

2 * ( 7- 8x ) =  1

2* 7 - 2 * 8x = 1

14 - 16x = 1

   - 16x = 1-14

   -16x = -13

       x = -13 /- 16

       x =13/16

The system of equations provided is classified as inconsistent because the equations have equal slopes but different y-intercepts, indicating they are parallel lines without any intersection point.

To classify the system as independent, dependent, or inconsistent without graphing, we need to rearrange the equations into a common linear form, typically y = mx + b, where m is the slope and b is the y-intercept.

The given equations of the system are y = 4x + 6 and 1 - 8x + 2y = 12. Let's rewrite the second equation in the form y = mx + b, which results in y = 4x - 5.

Now, let's compare. The first equation has a slope of 4 (m1 = 4) and the second equation also has a slope of 4 (m2 = 4). However, the y-intercepts of the two lines (b1 = 6, b2 = -5) are different.

Since the slopes are equal and the y-intercepts are different, the system is inconsistent. In other words, the two lines are parallel and do not intersect, so there is no solution to the system.

Answer:

[tex]-\sqrt{5} <x<5[/tex]

Step-by-step explanation:

The given expression is

Population of 320 animals decreases at rate of 19 % = P = 320(0.81)t

What is percentage ?

Percentage means how much per hundredth.

we can write 20% as `1/5 in fraction. when we multiply a fraction by 100 we get the result in percentage.

In the given question

Population (P) = 320

Annual rate or per year decreasing percentage = 19%

As it decreases each year by 19% it retains (100 - 19)%= 81% of 320 animals

If your sister weighs 15 kg less we have:

[tex]y = n-15[/tex]

Where "y" represents the weight of his sister in kg.

To find how many times Mary is heavier than her sister, we must divide Mary's weight by her sister's weight.

We have then:

Answer:

Mary is [tex]N= \frac{n}{n-15}[/tex] times heavier than her sister.

Mary weighs[tex]\frac{n}{(n-15)}[/tex]heavier than her sister.

Explanation:

As we have given the data  in the question that  

Weight of marry = n kg

Weight of Marry sister = n-15 kg

Let Marry be ‘K' times heavier than her sister then it means that  

K=[tex]\frac{n}{(n-15)}[/tex]

Answer:

6

Step-by-step explanation:

The digit in the hundredth place value of 6.02 is 2, so it rounds down.

The number 6.02, when rounded to the nearest tenth, results in 6.0, as '2' in the hundredths place is less than '5' and requires rounding down.

Given the number 6.02, rounding to the nearest tenth means identifying what tenth it is closest to. The number in the tenths place is '0'. For rounding, we look at the digit following the tenths place, which is the hundredths place. Here, the number is '2'. If this number is 5 or more, we round up. If it's 4 or less, we round down. So, 6.02 to the nearest tenth, would be 6.0 because 2 is less than 5, so we round down.

To find the equation of a line that is parallel to the given line and passes through the point (-2, 2), we follow these steps:

1. Determine the slope of the given line. Parallel lines have the same slope.

2. Use the point-slope form of a line equation with the given point and the determined slope to find the equation of the parallel line.

From the graph, we can see that the given line passes through points (0, -3) and (-5, -4). To find the slope (m) of the line, we use the slope formula:

[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

Substituting the given points, we get:

[tex]\[ m = \frac{-4 - (-3)}{-5 - 0} \][/tex]

[tex]\[ m = \frac{-4 + 3}{-5} \][/tex]

[tex]\[ m = \frac{-1}{-5} \][/tex]

[tex]\[ m = \frac{1}{5} \][/tex]

Now we have the slope of the parallel line, which is[tex]\( \frac{1}{5} \)[/tex]. The point-slope form of the line equation is [tex]\( y - y_1 = m(x - x_1) \)[/tex]. Plugging in the slope and the point (-2, 2), we get:

[tex]\[ y - 2 = \frac{1}{5}(x - (-2)) \][/tex]

[tex]\[ y - 2 = \frac{1}{5}(x + 2) \][/tex]

Now we simplify and solve for  y  to put it in slope-intercept form ( y = mx + b ):

[tex]\[ y - 2 = \frac{1}{5}x + \frac{2}{5} \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + 2 \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + \frac{10}{5} \][/tex]

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]

So the equation of the line that is parallel to the given line and passes through the point (-2, 2) is:

[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]
