For each 11 mm of coloured fabric June uses to make her curtains, she also uses 1 cm of white fabric. Express the amount of whit

avanturin [10]

Answer: The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$

Step-by-step explanation:

Given :

Amount of coloured fabric used by June = 11 mm = 1.1 cm (1 mm=0.1 cm)

Amount of white fabric used by June = 1 cm

To find : amount of white fabric to coloured fabric as a ratio in its simplest form

To find the ratio in simplest form , the units of both measurements should be same

Thus $\frac{\text {amount of white fabric}}{\text {amount of coloured fabric}}=\frac{1cm}{1.1cm}=\frac{10}{11}$

The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$

If y varies inversely as x, and y = 4 as x = 8, find y for the x-value of 2.

anyanavicka [17]

Because y varies inversely as x, instead of directly, you will need to multiply x by a fractional number (or divide x) in order to find y.
When x=8, y=4. Therefore, to find y, you need the "equation" y=(1/2)(x) or y=x/2.
So, when x=2, y=(1/2)(2) or y=2/2.
And so, y=1
Hope this helps!

S= 2Lw+2wh+5hL solve for h

cluponka [151]

$S=2Lw+2wh+5hL\ \ \ \ \ |subtract\ 2Lw\ and\ 2wh\ from\ both\ sides\\\\5hL=S-2Lw-2wh\ \ \ \ \ |divide\ both\ sides\ by\ 5L\\\\\boxed{h=\dfrac{S-2Lw-2wh}{5h}}$
