Answer:

V= -1/2

Step-by-step explanation:

You would have to add U+AT to get V

If A=-5 and T=1/2, then -5*1/2= -2.5 (A*T)

Then, adding U (which is 2), gives -.5, or -1/2

A pitcher of water contains 1/4 liters of water. The water is poured equally into 5 glasses.
vladimir2022 [97]

Answer:

a. 1/20 liters in each glass.

b. 50 ml in each glass.

Step-by-step explanation:

a. To find how many liters are in each glass, you have to divide the 1/4 liters by 5 glasses, because the water is poured equally.

\frac{1}{4}\:\div \frac{5}{1}  

Using the division properties of fractions:

\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}  

\frac{1}{4}\times \frac{1}{5} =\frac{1\times \:1}{4\times \:5} =\frac{1}{20}  

b. Use the rule of three to convert from liters to milliliters.

  • 1 l = 1000 ml
  • 1/20 l = x ml

Now, multiply 1/20 l by 1000 ml and divide by 1 l to obtain x.

x =\frac{ \frac{1}{20}\times 1000 }{1} = \frac{1000}{20} = 50
