8 0

Answer:

0

Step-by-step explanation:

First, in order to subtract these fractions, we need the denominators to be the same number.

4/8 x 2 = 8/16

1/2 x 8 = 8/16

8/16 - 8/16 = 0. The doctor does not need any Robitussin at all

Bryan has a square parcel of land that is 120 yards long and 120 yards wide. The land is planted with Bermuda grass and surround
Mekhanik [1.2K]
The diagonal fencing will be the hypotenuse of a right triangle with sides 120yds long so:

h=√2(120^2))

h=√28800 yd

And the surrounding fencing will just be four times the side length of 120yds so:

s=480yd

So the total fencing needed is:

f=480+√28800 yards

f≈649.71 yd  (to nearest hundredth of a yard)  which is

f≈650 yds  (to nearest whole yard)

But, I wasn't sure, if they just want the diagonal fencing needed then it is just:

f=√28800

f≈170 yds  (to nearest yard)

Divide $200 in the ratio 3:2. What is the result?
s2008m [1.1K]

Answer:

b) $120 , $ 80

Step-by-step explanation:

Ratio = 3 :2

Total = 3 + 2 = 5

3/5 of 200 = \frac{3}{5}*200

                  = 3 * 40

                  = $ 120

2/5 of 200 = \frac{2}{5}*200

                 = 2 * 40

                  = $ 80
