Lisa [10]3 years ago

Answer:

She has 15 more purple rocks than blue.

Step-by-step explanation:

purple= 2/3 of all rocks

blue= 3/4 of all rocks that aren't purple

silver= 3 (or 1/4 of all rocks that aren't purple)

if 3 (silver) is 1/4 of all rocks that aren't purple, blue (3/4) is 3x3=9

if purple is 2/3 of all rocks, blue and silver are 1/3 of all rocks

so 1/3 of all rocks would be 9+3=12

if 1/3=12, then 2/3 (purple)=24

-----

At this point:

purple=24

blue=9

silver=3

-----

purple (24) - blue (9) =15

She has 15 more purple rocks than she does blue.

Find the 100th term in the arithmetic sequence 0,5,10,15
Viktor [21]

Answer:

easy peasy,

the 'n' th term of any arithmetic sequence can be found with the following formula

=> a + ( n-1) d, [where 'a' if the first term of the sequence, 'n' the number of term we need to find, and 'd' being the common difference between each two consecutive term of the sequence)

all in this case would be,

a = 0

n = 100

d = +5

hence the 100th term would be,

=>  0 + (100 - 1) 5

=> 99 x 5

=> 495

Please help itz year 8 maths​
mariarad [96]

We need a 2 and a 3 to produce a six. Because we are dividing by "2^{4}*3^{2}"...

We need a "2^{5}*3^{3}" in the numerator.

In this way, x+y = 5+3 = 8.

answer: 8
