If you flip over the x-axis A' would be (1, -1) (just change the sign on the x)
Then rotate 180 reverse the points to get A'' at (-1, 1)
Question #1:
To find the percentage of boy's in the class, divide.
9 / 36 = 0.25
0.25 * 100% = 25% (boys in the class)
We can write this proportion as 9/36 since this is the same as 25%.
_________
Question #2:
We know that the ear buds in both options cost $125.
The earbuds online are on a 20% discount.
The earbuds in store are on a 90$ sale
Lets find the discount for the online pair.
20% = 0.2
125 * 0.2 = 25
125 - 25 = $100 (price after discount)
After solving we can see that the earbuds in store are a better price. So, you will purchase the ear buds in store.

Answer:
As per the given statement:
The distance from jack eyes to the top of the tower = 50.64 m
Also, jack and john eyes are 1.5 m from the ground.
Labelled diagram as shown in the attachment
Let BC = x m be the distance of the jack from the base of the tower and
AG = y m be the distance above 1.5 m from the the ground.
Using tangent ratio:
In triangle AGE;
Here, AG = y m and EG = 20+x m
then;
or we can write this as;
........[1]
Similarly, in AGF;
then;
or
......[2]
Substitute equation [2] into the equation [1], to solve for x;
or
Using distributive property:
we have;
Subtract 0.84 x from both sides we get;
Divide both sides by 0.892 we get;
Therefore, 18.8 meter johns from the base of the tower.
