Lubov Fominskaja [6]

Answer:

0.5 liters of milk are available per child.

Step-by-step explanation:

Amount of milk available per children:

The amount of milk, in liters, available for x children is given by:

m(x) = \frac{25}{x}

50 children are present on a day

This means that x = 50

How much milk is available per child?

This is m(50). So

m(50) = \frac{25}{50} = 0.5

0.5 liters of milk are available per child.

A prism is dilated by a factor of 1.5. How many times larger is the volume of the resulting prism than the volume of the origina
Margarita [4]
By the term dilated we mean to say that the dimensions of the new polyhedron is increase to a certain size by that times. For the volume, this dilation scale should be cubed in order to determine the number of times the volume of new figure is larger than the original.
                                    r = (1.5)³
                                      = 3.375
Thus, the volume of the new prism is 3.375 times larger than the volume of the original prism.

Lashonda purchased a prepaid phone card for $20. Long distance calls cost 8 cents a minute using this card. Lashonda used her ca
Gre4nikov [31]

We know that

• Lashonda purchased a prepaid phone card for $20.

,

• Long-distance calls cost 8 cents a minute.

,

• The remaining credit on her card is $17.12.

This problem can be expressed as

20-0.08x=17.12

Where <em>x</em> is the number of minutes.

We solve the equation for <em>x</em>

\begin{gathered} -0.08x=17.12-20 \\ -0.08x=-2.88 \end{gathered}

Then, we divide by -0.08 the equation

\begin{gathered} \frac{-0.08x}{-0.08}=\frac{-2.88}{-0.08} \\ x=36 \end{gathered}<h2>Therefore, Lashonda's call last 36 minutes.</h2>
