Mathematics help please!!!!!!!!!<br><br> what is -0.0833333333333 converted into a fraction?

VladimirAG [237]

Answer:

- 1/12

Step-by-step explanation:

Let -0.0833333 = x --- (1)

Multiply both sides by 10.

-0.833333 = 10x --- (2)

Subtract (2) from (1),

0.75 = -9x

-9x = $\frac{75}{100}$

= $\frac{3}{4}$

$x=-\frac{3}{36}$

$x=-\frac{1}{12}$

A lampshade has a height of 12cm and upper and lower diameters of 10cm and 20cm A)what area of material is required to cover tha

netineya [11]

Answer:

$(a)\ Area = 195\pi$

$(b)\ Volume = 700\pi$

Step-by-step explanation:

Given

$h = 12$

$d_1 = 10$ --- lower diameter

$d_2 = 20$ --- upper diameter

Solving (a): The curved surface area

This is calculated as:

$Area = \pi l(r_1 + r_2)$

Where

$r_1 = 0.5 * d_1 = 0.5 * 10 = 5$ --- lower radius

$r_2 = 0.5 * d_2 = 0.5 * 20 = 10$ --- upper radius

And

$l = \sqrt{h^2 + (r_1 - r_2)^2$ ---- l represents the slant height of the frustrum

$l = \sqrt{12^2 + (5 - 10)^2$

$l = \sqrt{12^2 + (-5)^2$

$l = \sqrt{144 + 25$

$l = \sqrt{169$

$l = 13$

So, we have:

$Area = \pi l(r_1 + r_2)$

$Area = \pi * 13(5 + 10)$

$Area = \pi * 13(15)$

$Area = 195\pi$

Solving (b): The volume

This is calculated as:

$Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))$

This gives:

$Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))$

$Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))$

$Volume = \frac{1}{3}\pi * 12 * (175)$

$Volume = \pi *4 * 175$

$Volume = 700\pi$

Match the mean median mode and range for the data set below 16 9 20 10 12 6 8 15

blsea [12.9K]

Answer:

12 is mean 11 is median range is 14

Step-by-step explanation:

For the Mean

Add all the numbers up

16 + 9 + 20 + 10 =55

12 + 6 + 8 + 15 = 41

55 + 41 = 96

There are 8 numbers so we divide by 8

96/8 = 12

Range is Smallest number minus biggest so 20 - 6 = 14
