50%. 60/2=30 or 60*.5=30. Dividing by two or multiplying by .5 are the same as taking 50%, meaning that there was a 50% discount
Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm All sides of a square are equal
BE = 1/2 BC Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2 Perform the sqrs
AE^2 = 400 + 100 Add the terms
AE^2 = 500 Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4
Hello,
A good first step to take would be to calculate how much of a barrel John and Mary can drink together in 1 day.
If John can drink 1 barrel in 6 days, then every day he can drink 1/6 of a barrel.
If Mary can drink 1 barrel in 12 days, then every day she can drink 1/12 of a barrel.
Every day, the total that John and Mary can drink will be (1/6) + (1/12) = (1/4) of a barrel.
If we want to know how many days it will take for them to drink 1 barrel of water together, and they drink 1/4 of a gallon every day, we do
(1) / (1/4) = 1 * (4/1) = 4 days
It will take 4 days for John and Mary to drink 1 barrel together.
Hope this helps!
