A transversal is a line that intersects two or more other lines. When it intersects parallel lines, many angles are congruent. Parallel lines are two lines that are always the same distance apart and never touch.

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 x - y =5, x + y =1, then x^2 - y^2= ?? +explanation please and thanks

Sveta_85 [38]

<h3>Answer: 5</h3>

=================================

Explanation:

Apply the difference of squares rule

x^2 - y^2 = (x-y)(x+y)

x^2 - y^2 = (5)(1)

x^2 - y^2 = 5

----------

Alternatively, you can solve the system

$\begin{cases}x-y=5\\x+y = 1\end{cases}$

for x and y to get (x,y) = (3,-2).

Then compute x^2-y^2 = 3^2-(-2)^2 = 9-4 = 5
