Answer:
10cm ( A )
Step-by-step explanation:
This would use the Pythagorean Theorem. That means it would be -
a^2_b^2= c^2, in this case, you have 2 of your legs already so those two values would be a&b. you would stick those two into the equation and it should look like this:
6^2+8^2=c^2
then 36+64=c
and then 100=c
after that, you would take the square root of c to get
10!
It would be your first answer because since the MN is a positive you have to subtract it to move it to P and you solved for Q
5/20 can also be represented as 25/100 or 25%. The can be done by multiplying the top and bottom both by 5 and then dividing our numerator (25) by our denominator(100) to get the %.
Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
