Answer:
The correct option is 1.
Step-by-step explanation:
Given information: The coordinates of a right angled triangle ABC are A(0, 0), B(0, 4a – 5) and C(2a + 1, 2a + 6). Angle ABC = 90°.
It means AB and BC are legs of the right angled triangle ABC.
Side AB lies on the y-axis because the x-coordinate of both A and B is 0.
Two legs are perpendicular to each other. So, BC must be parallel to x-axis and the y-coordinate of both B and C is must be same.
Divide both sides by 2.
The value of a is 2. So the coordinates of triangle ABC are
The area of a triangle is
The area of triangle ABC is
The area of triangle ABC is 102. Therefore the correct option is 1.
A) 95.8 % of £36 will be the new price
B) The answer to part A as a decimal is £34.488
C) The new price is £34.488
<h3><u>Solution:</u></h3>Given that the price of a pedicure decreases by 4.2% from £36 on promotion
<em><u>A) What percentage of £36 will the new price be ?</u></em>
Given that £36 is decreased by 4.2 %
New price = 36 – 4.2% of 36
Now we have to find what percentage of £36 will the new price be
x % of 36 = 34.488
<em><u>B) Write your answer to part a as a decimal.</u></em>
Now, we have to find the new price in decimal form.
<em><u>C) Work out the new price.</u></em>
As we calculated, the new price is £34.488
