Step-by-step explanation:
Leg^2 +leg^2=hypotenuse^2
Let’s pretend you have a triangle
/|
/ |
/ |
/ | 6

/__ |
8
Leg^2+leg^2=hypotenuse^2
6^2+8^2=x^2
36+64=x^2
100=x^2
Now to get x by itself you need to get rid of ^2
You do this by squat rooting both sides. The square root of 100 is 10 (10•10=100)
So 10=x
Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C
Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.
Lets turn E into x and F into y.
We already know that x is 0.8. And if y/x = 0.6, we have to figure that out.
y/x = 0.6
y/0.8 = 0.6
Multiply by 8 to get y = 0.48.
So we have to find P(xy)
So if we know that x = 0.8 and y = 0.48 then all we have to do is multiply 0.48 and 0.8.
0.48 * 0.8 = 0.384
P(E and F) is 0.384.
