Step-by-step explanation:

well, 3.6 meters cost $67.14

how much is 1 meter ?

right !

67.14 / 3.6 = $18.65

so, the price in $ per meter or $/m is $18.65.

Answer:

Step-by-step explanation:

a. 2x + 36

2. 6a + 15b

3. 35x + 15y

4. 3p + 2q

5. 3a + 8

Answer:

y= 1/2x -7

Step-by-step explanation:

Find the y-intercept. It is where the line crosses "y" which is -7

Next find the rise and the run for "x"

Rise - 1

Run - 2

Then put them in slope intercept form

y=1/2x -7

Answer:

90 km per hour

Step-by-step explanation:

divide total distance by number of hours traveled :)

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\sqrt[3]{x^5-3}\implies \stackrel{\textit{quik switcheroo}}{x = \sqrt[3]{y^5-3}}\implies \stackrel{\textit{cubing both sides}}{x^3=y^5-3} \\\\\\ x^3+3=y^5\implies \sqrt[5]{x^3+3}=\stackrel{f^{-1}(x)}{y}[/tex]

Answer:

adults : 0  children: 600

Step-by-step explanation:

x + y = 600

6x＋4y = 2400

4×(x + y = 600) = 4x＋4y = 2400

(6x＋4y = 2400) － (4x＋4y = 2400) = x=0

so y=600

Answer:

2.5

Step-by-step explanation:

37.5 divided by 15 which is 2.5 because you'd do the inverse. you know the method for area is base times height and in this case you know base and total area so you'd divide.

You can use the fact that the corresponding values from both the columns are taken into ordered pair (x,y) form to plot them on the 2d graphs (for 2 data values' set)

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

There are two axis in the graph. Horizontal axis and vertical axis. The independent variable is plotted on horizontal axis and dependent variable's values are plotted on vertical axis.

Since the temperature is measured on each value of depth, thus, depth is independent and temperature is depending on the depth.

The data points are ordered as

(independent variables' value, dependent variables' value at that value of independent variable)

Thus, for the given table, we will have:

(0, 23.5), (500, 12), ... points.(it is denoting like what was the value of second variable when first variable was this. Like when depth was 0, temperature was 23.5 degrees Celsius, and so on).

Thus,

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

Answer:

835.2

Step-by-step explanation:

Add the ratio together; 7+5=12

Divide; 835:12=69.5833333 / if needed, round the number with decimals -> 69.6

Multiply the number you have with each of the ratio numbers. 69.6×7=487.2 and 69.6×5=348

487.2+348=835.2

Answer:

19/50 as a decimal is 0.38.

Step-by-step explanation:

Answer:

Mean: 11.6

Median: 14

Mode: 18

Range: 17

Step-by-step explanation:

Mean: add all of the numbers and divide by how many numbers there are

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Mode: the number that occurs the most

Range: Subtract the minimum data value from the maximum data value to find the data range. In this case, the datarange is 18−1=17

Answer:

r = 5.848cm, h = 11.696cm

Step-by-step explanation:

Surface area: [tex]SA=2\pi rh+2\pi r^2[/tex]

Volume: [tex]V=\pi r^2h[/tex]

Therefore, the height of a cylinder given its volume would be [tex]h=\frac{V}{\pi r^2}[/tex], thus:

[tex]SA=2\pi r(\frac{V}{\pi r^2})+2\pi r^2\\\\SA=\frac{2V}{r}+2\pi r^2\\\\SA=\frac{2(400\pi)}{r}+2\pi r^2\\\\SA=\frac{800\pi}{r}+2\pi r^2[/tex]

We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:

[tex]\frac{d(SA)}{dr}=-\frac{800\pi}{r^2}+4\pi r[/tex]

[tex]0=-\frac{800}{r^2}+4\pi r[/tex]

[tex]0=800\pi+4\pi r^3[/tex]

[tex]-800\pi=4\pi r^3[/tex]

[tex]-200=r^3[/tex]

[tex]r\approx5.848[/tex]

If [tex]0If [tex]r>5.848[/tex], then the surface area of the cylinder increases

Therefore, the surface area is minimized when the radius is [tex]r=5.848cm[/tex], making the minimum height [tex]h=\frac{V}{\pi r^2}=\frac{400\pi}{\pi(5.848)^2}\approx11.696cm[/tex].

In conclusion, the 2nd option is correct.

Answer: 52 Dogs

Hi, I hope this helps you :D Good Luck !

Step By Step:

Let d = number of dogs

b = number of birds

d+b = 71

Birds have 2 legs and dogs have 4 legs

4d+2b = 246



Multiply the first equation by -2

-2d-2b = -142

Add this to the second equation



-2d-2b = -142

4d+2b = 246

--------------------------

2d  + 0b = 104

Divide each side by 2



2d/2 = 104/2

d = 52



There are 52 dogs
