Answer:

Inequality that represents the amount paid by neighbors of Dani will be

x ≤ 8 + (4 + 16)

Step-by-step explanation:

Let the neighbors of Dani paid her to take care of their bird = $x

Danny spent on an afternoon snack = $4

She paid the amount for a new book = $16

Now the amount left with her is at least $8.

Therefore, inequality which represents the amount paid by her neighbor will be

x - 4 - 16 ≤ 8

x ≤ 8 + (4 + 16)

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.

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