--------------------------------------------------------------
Find capacity of the glass :
--------------------------------------------------------------
Volume of the glass = πr²h 
Volume of the glass = π(5)²(2) 
Volume of the glass = 157.08cm³

--------------------------------------------------------------
Find the volume of the milk :
 --------------------------------------------------------------
If the glass is half full, 
Volume of the milk = 177.08 ÷ 2
Volume of the milk = 78.54 cm³

--------------------------------------------------------------
Convert cm³ to ml :
--------------------------------------------------------------
78.54cm³ = 78.54 ml

--------------------------------------------------------------
Answer: There is 78.54 ml of milk in the glass.

nataly862011 [7]

Answer:

The length of the field on the drawing is 55 cm.

Step-by-step explanation:

Given:

Mark made a scale drawing of a soccer field.

Using a scale of .5 cm=1 m.

The actual length of the field is 110 m.

Now, to find the length of the field on drawing.

Let the length of the field on drawing be x.

As given 0.5 cm is equivalent to 1 m.

Thus, x is equivalent to 110 m.

Now, to get the length of the field on drawing by using cross multiplication method:

\frac{0.5}{1} =\frac{x}{110}

<em>By cross multiplying we get:</em>

⇒ 55=x

⇒ x=55

Therefore, the length of the field on the drawing is 55 cm.

The product of two integers is 72.one number is two less than 5 times the other
harkovskaia [24]
X*y=72
x = 5y-2

x=72/y
72/y=5y-2

72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18

(18,4)
