vaieri [72.5K]

Answer:

Susan makes 5 fruit cups

each fruit cup has 5 strawberries and 3 kiwis

so the number of strawberries used is - 5 x 5 = 25 strawberries

and the number of kiwis used - 5 x 3 = 15 kiwis

so the total number of fruits - 25 + 15 = 40 fruits

Joanna uses 40 fruits to make 4 fruit cups

each cup she uses 8 strawberries

therefore total number of strawberries she uses - 8x 4 = 32 strawberries

she has 40 fruits in total and 32 of those are strawberries

the rest are kiwis

number of kiwis = 40 -32 = 8

8 kiwis are there and she has to make 4 cups

so for each cup number of kiwis = 8 / 4 = 2

so each cup has 2 kiwis

ln(y+1)-lny=1+3lnx . Express y in terms of x, in a form not involving logarithms. (4 marks, Maths CIE A level)

Delicious77 [7]

$remember$
$ln(x)=log_e(x)$
$and$
$log_x(a)-log_x(b)= log_x( \frac{a}{b} )$
$and$
$log_a(b)=c$ means $a^c=b$
$and$
$blog(a)=log(a^b)$

$so$

$ln(y+1)-ln(y)=1+3ln(x)$
$ln( \frac{y+1}{y} )=1+ln(x^3)$

$minus$ $ln(x^3)$ $from$ $both$ $sides$

$ln( \frac{y+1}{y}-ln(x^3) )=1$
$ln( \frac{y+1}{yx^3})=1$
$log_e( \frac{y+1}{yx^3})=1$

$translate$

$e^1=\frac{y+1}{yx^3}$
$e=\frac{y+1}{yx^3}$

$times$ $both$ $sides$ $by$ $yx^3$

$eyx^3=y+1$

$minus$ $y$ $from$ $both$ $sides$

$eyx^3-y=1$
$y(ex^3-1)=1$

$divide$ $both$ $sides$ $by$ $(ex³-1)$

$y= \frac{1}{ex^3-1}$

Lubov Fominskaja [6]

Firstly figure out how much money you earn per one hour. This is 312$ divided by 20 is 16$/hour. Then write an equation which represents only hourly earnings: y = 16x. To answer the last question just enter the value for variable x = 15, and you will get money earned per one week.
