You are adding fractions. To add fractions, they all must have the same denominator.

We are adding 2/3 + 1 1/2 + 1/4.

First, let's turn that mixed number (1 1/2) to an improper fraction.

Multiply the whole number by the denominator: 1*2=2

Add that to the numerator: 2+1=3

Write that over original denominator: 3/2

2/3 + 3/2 + 1/4

Okay, now we need common denominators.

What is the LCM (lowest common multiple) of 3, 2, and 4? The lowest common multiple is the lowest number that they all equal when multiplied by something. The LCM is 12.

3*4=12

2*6=12

4*3=12

When multiplying the denominators by the LCM, you must also do the same to the numerators!

Make sure to multiply the numerators by the same number you multiplied by the fractions!

So now we have:

8/12 + 18/12 + 3/12

So now that our denominators are all the same, all you have to do is add the numerators and keep the denominators the same!

8+18+3=29/12

29/12 is our answer. We could also changed this to a mixed number and reduce.

12 goes into 29 evenly 2 times, with a remainder of 5. Keep the denominator. Mixed number form is 2 5/12. This can't be reduced (5 is prime) so Ms. Martinville needs 2 5/12 altogether!

60 POINTS BRAINLIES

Answer:

see below

Step-by-step explanation:

a) median : re-arranged the numbers in order. i.e. min to max

gold: 147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022

212 + 227 = 219.50

silver: 147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794

178 + 241 = 209.50

bronze: 151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704

193 + 260 = 226.50

b) mean : sum of all numbers divide by n, where n=10

gold: = (147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022 ) / 10

= 311.40

silver: = (147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794 ) / 10

= 282.30

bronze: = (151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704 ) / 10

= 280.60

c) standard deviation on population (STDEV.P)

Australia = 16.44

china = 33.03

france = 19.74

germany = 30.21

great britain = 13.89

hungary = 12.04

italy = 11.44

soviet union = 48.46

sweden = 13.47

united states = 133.84

Please answer correctly

Inga [223]

Answer:

A.v=п*1/4*S^3

Step-by-step explanation:

the formula for the volume of a cylinder is v=п*r^2*h. here r=d/2=S/2 so r^2=S^2/4. h is the same lenght as the side of the cube so h=s. and then you just have to substitute r and s in the formula
