Answer:

$\frac{338}{99}$ is the answer.

Step-by-step explanation:

let x = 3.4141.....

multiplying both sides by 100 [ since it has two repeating decimals],we get

100x 341.4141...

subtracting from the first ,we get

99x = 338

so x = $\frac{338}{99}$

Remark

I'm going to assume that it is just the 0.41 that is doing the repeating. If it is not leave me a note.

Solution

The trick is to call x = 3.4141414141 ....

then multiply by 100

100 x = 341.4141414141 ............ Now write the original decimal underneath.

<u>. . . x = 3.414141414141 ......</u>...... Subtract

99 x = 338 That's all that's left. The decimal part cancels out.

x = 338 / 99 Fractional answer.

x = 3 39/99

x = 3 13/33 If this isn't one of your answers, leave me a note.

serious [3.7K]

Median won't change, however Mean will fall by 180.

<h3>What do mean and median?</h3>

By summing all the numbers in a data collection and dividing by the total number of values in the set, one may get the mean (average) of the data set. When a data collection is sorted from least to largest, the median represents the midpoint value.

African elephants total 555 in number.

Elephants had a 3800 kg average mass.

Elephants had a 3600 kg median mass.

Lola, the elephant that was the smallest, weighed 2700 kg.

Later, Lola became really ill and lost a lot of weight, reaching a mass of 1800 kg.

What effect will Lola's weight loss have on the mean and median as well as Currently, the median is 3600 and the lowest is 2700.

now 2700 becomes 1800

so Median remains the same as 3600

No change in Median

The mean mass of the elephants was 3800 kg

=> total weight = 5 x 3800 = 19000 kg

2700 kg becomes 1800 kg

Hence new total mass = 19000 - 2700 + 1800 = 181000 kg

New Mean = 18100/5 = 3620 kg

Mean reduced by 3800 - 3620 = 180 kg

No change in Median weight

Mean reduced by 180 kg

A sphere has a surface area of about 999 square millimeters. What is the radius, in millimeters, of the sphere

motikmotik

Given that, a sphere has a surface area of about 999 square millimeters.

Formula to find the surface area of sphere is,

S= 4πr² Where r = radius of the sphere and S= surface area.

Given S= 999 square millimeters.

So, we can write:

4πr² = 999

4 * 3.14 * r² = 999 Since, π = 3.14

12.56 *r² = 999

$r^2=\frac{999}{12.56}$ Divide each sides by 12.56.

r² = 79.53821656

r = √79.53821656 Taking square root to each sides of equation.

r = 8.918420071

So, r = 8.918 Rounded to nearest thousandth.

So, radius of the sphere is 8.918 millimeters.

Hope this helps you!

Serggg [28]

Answer:

$156.35

Step-by-step explanation:

we know that

A group of friends went to lunch, and their bill was $132.50

In this problem

$132.50 represent the 100%

100%+18%=118%

using proportion

Find out the total amount that represent 118%

Let

x ----> the total amount of the bill

$\frac{\$132.50}{100\%}=\frac{x}{118\%}\\\\x=132.50(118)/100\\\\x=\$156.35$
