Answer:

Rational.

Step-by-step explanation:

\textbf{A rational number is a real number that can be expressed as}~ \dfrac{p}{q},\\\\\textbf{where}~ p~ \textbf{and}~ q~ \textbf{are integers.}\\\\ \boxed{50.2 = \dfrac{502}{10}}\\\\ \textbf{50.2 can be expressed as a ratio of two integers,}~ \textbf{so it is a rational number.}

four time the first of three consecutive integers is six more than the product of two and the third integer. find the integers.
maw [93]
<span>
Assign variables : 
Let x = first consecutive even 
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even 
4x = 6 + 2(x+4) 
4x = 6 + 2x + 8 
4x = 2x + 14 
4x - 2x = 14 
so your answer is 7,9and 11</span>

A cone-shaped water tank is completely filled. The tank has a depth of 12 feet and a radius of 29 feet. A pump removes water fro
Sauron [17]

Answer:

Volume = 10562.96  cu ft

10.56 hr. to drain all the water

Step-by-step explanation:

V = 1/3Bh        B = area of the base           h = height

The base is a circle, so B = \pi r^{2}

V = \frac{1}{3} (3.14) (29^{2})(12) = 10562.96  cu ft

10562.96/1000  = 10.56 hr.

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i
Elden [556K]

The correct proportions are given as follows:

  • x = 3, y = 27: 9/1.
  • x = 9, y = 81: 9/1.
  • x = 21, y = 126: 6/1.
  • x = 14, y = 84: 6/1.
  • x = 12, y = 36: 3/1.
  • x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

  • x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
  • x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
  • x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
  • x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
  • x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
  • x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

a microscopic organism is shown in a Biology book with a length of 5.6 centimeters. If the scale of the picture is 2000:1, find
Assoli18 [71]

Assuming that 2000:1 is a ratio of unknown units to centimeters, we can use proportions to find the actual length of the organism.

\frac{2000}{1} = \frac{x}{5.6}

x = 2000(5.6)

x = 11200

The actual length of the organism is 11,200 units.
