Order 0.40mm, 40mm , 0.4 mm, and 0.004mm from most to least precise

Answer:

square root of 40

Step-by-step explanation:

a^(2)+b^(2)=c^(2)

3^(2)+b^(2)=7^(2)

9+b^(2)=49

9-9+b^(2)=49-9

b^(2)=40

sqr b^(2)=sqr 40

b=6.32455532034

therefore,the square root of 40 is the answer

The two names for the​ segment are AC and CA that has endpoints A and C the answer would be AC and CA.

A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.

It is given that:

A segment has endpoints A and C.

As we know, the line segment is the line that goes to the endpoints on both sides.

The line segment can be represented as AC and CA

Or

The bar(AC) and bar(CA)

Thus, the two names for the​ segment are AC and CA that has endpoints A and C the answer would be AC and CA.

To graph the equation f(x) = -3/4x - 4, choose values for x, substitute them into the equation to find corresponding y values, and plot the points on a graph.

The given equation is f(x) = -3/4x - 4. To graph this equation, we can choose several values for x and substitute them into the equation to find the corresponding values for y. Then, we plot these points on a coordinate plane and connect them to form a line.

For example, let's choose x = 0. Substituting this value into the equation, we get f(0) = -3/4(0) - 4 = -4. This gives us the point (0, -4) on the graph. Similarly, we can choose other values for x and find their corresponding y values to plot more points and complete the graph of f(x).

Using a system of equations, it is found that for the room's dimensions:

The perimeter of a rectangle of length l and width w is given by:

[tex]P = 2(l + w)[/tex]

The length of a rectangular room is 2 feet longer than twice the width, hence:

[tex]l = 2w + 2[/tex]

The room's perimeter is 196 feet, hence:

[tex]2l + 2w = 196[/tex]

From the second equation:

[tex]2(2w + 2) + 2w = 196[/tex]

[tex]6w = 194[/tex]

[tex]w = \frac{194}{6}[/tex]

[tex]w = 32.33[/tex]

Then:

[tex]l = 2w + 2 = 2(32.333) + 2 = 66.67[/tex]

The dimensions of the room are 32 feet by 66 feet, with a total area of 2112 square feet, which can be calculated for carpet replacement based on the room's perimeter.

To find the dimensions of a rectangular room where the length is 2 feet longer than twice the width and the perimeter is 196 feet, we first need to establish equations based on the given information. Let the width of the room be represented by w and the length be represented by l. From the problem, we have that l = 2w + 2. The perimeter P of a rectangle is given by P = 2l + 2w. Plugging in what we know, we can set up the equation:

196 = 2(2w + 2) + 2w

Solving this, we get:

Now, we use the width to find the length:

So, the dimensions of the room are 32 feet by 66 feet. Since the student wants to determine the square footage for carpet replacement, we can calculate the area by multiplying the length and width:

Area = 32 feet × 66 feet = 2112 square feet

Answer:

(3a,a)

Step-by-step explanation:

Yes, the function y=8x is a linear function because it has the form y = a + bx, where a is the y-intercept and b is the multiplicative slope factor, both of which are present in this equation with a=0 (implied) and b=8.

The question whether y=8x is a linear function can be answered by examining the form of the equation. A linear equation can generally be expressed as y = a + bx, where a is the y-intercept and b is the slope of the line. Since the equation y=8x fits this form, with a slope of 8 and a y-intercept of 0 (implied), it is indeed a linear function. A graph representing this equation would display a straight line with a slope of 8, confirming its linear nature. The equation y=xb is nonlinear when b is a power rather than a multiplicative parameter, demonstrating the contrast between linear and nonlinear functions. However, in our case, 8 is simply a multiplicative factor, which is characteristic of a linear function.

The required inequality is -6<x<8

An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.

Given here: A number x is more than -6 and at most 8.

Clearly we can infer that the number lies between the interval (-6,8)

Thus we can construct the inequality for x as

-6<x<8 or x has 11 integral values

Hence, The required inequality is -6<x<8

Answer:

As mention in the explanation steps.

Step-by-step explanation:

Te following steps may be helpful for using a compass and a straightedge to construct a line perpendicular to a given line through a point not lying on the given line (as shown in the figure).

Step - 1. Draw a line (line AB)

Step- 2. Take a point (point P), that do not lie on the line AB.

Step - 3. Assume point p as a center an draw as arc which intersect the line AB at two point (point C and point D).

Step - 4. Now draw a line XY that is  the perpendicular bisector of line segment CD. This recurred line XY is the  line perpendicular to a given line (line AB) through a point not lying on the given line.

Use the tool that has solid dots at both ends

Explanation :

Plot the inequality on the number line.

−7≤x≤−2

We start plotting the point at -7. we use closed circle at -7 because we have less than or equal to sign at -7

Now we plot another point at -2. here also we use closed circle that is solid circle .

Now shaded the region between -7 and -2 because x lies between -7 and -2

a. We are given that the formula for Celsius (c) to Kelvin (k) is:

k = c + 273.15

Now to solve for the formula for c, simply subtract 273.15 from both sides, so that:

k – 273.15 = c + 273.15 – 273.15

k – 273.15 = c

Rearranging:

c = k – 273.15

b. We are given that k = 300 Kelvin, therefore find for c:

c = k – 273.15

c = 300 – 273.15

c = 26.85°C

The formula to convert temperature from Kelvin to Celsius is c = k - 273.15. When you use this formula to convert 300 Kelvin to Celsius, the answer is 26.85°C.

The formula k = c + 273.15 is used to convert temperatures from Celsius to Kelvin. To solve for 'c' (Celsius), you would subtract 273.15 from both sides of the equation which gives c = k - 273.15.

If you have a temperature of 300 Kelvin and you want to convert this to Celsius using the formula c = k - 273.15, you would substitute 300 in place of k. This gives: c = 300 - 273.15, which equals 26.85°C.
