Subtract to find the amount of the discount:
80.00 - 60.00 = 20.00
Divide the amount of discount by original price:
20.00 / 80.00 = 0.25
Multiply by 100 to get percent:
0.25 x 100 = 25%
Answer: 25%
7 1/2 - 1 1/4 = 7 2/4 - 1 1/4 = 6 1/4
By pythagorean theorem
a^2+b^2=c^2
We can find that PL is 12.65
and then by altitude theorem
MA*LA=PA^2
we can find the value of MA
12MA=16
MA=1.33
then by the pythagorean theorem
we can use to find PM
MA^2+PA^2=PM^2
so PM=4.22
then to find the are you multiply length by width
PM*PL
12.65*4.22
So the area is 53.38
Step-by-step explanation:
Amount of orange juice in 400ml glass
= 400ml * (40%/100%) = 160ml.
Amount of orange juice in 300ml glass
= 300ml * (1/2) = 150ml.
Since 150ml < 160ml, the 300ml glass contains less orange juice.
A^2-64=0 you can factor like this:
(a+8)(a-8)=0 and since a>0, a must be 8
or you can do this:
add 64 to both sides of the equation leaving you with:
a^2=64 taking the square root of both sides
a=(-8,+8) and since a>0, a=8
