8.2<br> 5. In a '70% off' sale, a hat was £33.60.<br> Work out the original price.

Aleks [24]

100% - 70% = 30%

30% of what = £33.60?

Let p = original price

0.30p = 33.60

p = 33.60 ÷ 0.30

p = £112

PLEASE PLEASE HELP WITH THIS

Phoenix [80]

Since triangles ABC and BCD are similar, we can establish a proportion between the lengths of corresponding sides:
$\frac{AC}{BC} = \frac{BC}{CD}$

We can infer from our picture that $BC=m$ . Also we can find the length of AC by adding AD and CD:
$AC=AD+CD$
$AC=11+7$
$AC=18$

Lets replace the values in our proportion:
$\frac{AC}{BC} = \frac{BC}{CD}$
$\frac{18}{m} = \frac{m}{7}$
Solving for $m$ :
$m^2=(18)(7)$
$m^2=126$
$m= \sqrt{126}$

We can conclude that the correct answer is: D $\sqrt{126}$

Write he standard form of the equation; Through: (-1,5) and (1,2)

JulsSmile [24]

Standard form is ax+by=c where a,b, and c are integers and a is usually positive

so
first find slope
get into form y=mx+b where m is slope
so
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
points (-1,5) and (1,2)
slope is (2-5)/(1-(-1))=-3/(1+1)=-3/2
y=-3/2x+b
find b
sub a point
(1,2)
2=-3/2(1)+b
2=-3/2+b
4/2=-3/2+b
7/2=b

y=-3/2x+7/2
add 3/2 both sides
3/2x+y=7/2
times 2 both sides
3x+2y=7 is standard form
