<h3>Answer:</h3>

Option C

<h3>Solution:</h3>
  • Rational numbers can be expressed as a fraction in the form \displaystyle\frac{p}{q}, where p is the numerator and q is the denominator.
  • Now, which numbers can and cannot be expressed as a fraction?
  • First of all, can we express \sqrt{12} as a fraction? No, it's a surd.
  • Can we express \pi as a fraction? No. Remember, pi is irrational. It has an infinite number of digits after the decimal point (same with √12)
  • Can we express -\displaystyle\frac{3}{7} as a fraction? Sure. What's more, it's already a fraction.
  • Can we express √7 as a fraction? No. It's also irrational, like √12 and π.

Hope it helps.

In a box there are 21 identical pieces that have been enumerated using odd numbers from 5 to 45. How many tiles should be drawn
Orlov [11]

These are the only combinations of exactly 3 tiles that add to 33.

5,7,21

5,9,19

5,11,17

5,13,15

7,9,17

7,11,15

9,11,13

All tiles with numbers above 21 do not help you. 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45. There are 12 of them.

Every three-number combination must have one of the numbers 5, 7, or 9, so if the six numbers from 13 to 21 are picked, in addition to the 12 higher numbers mentioned above, you already picked 18 tiles, and you still have no solution. To obtain the solutions 5,7,21; 5,9,19; 7,9,17; he needs two more numbers in addition to the 18 he already has, so he needs 20 tiles in total to be guaranteed three of them add to exactly 33.

Answer: 20 tiles

Find the volume r:7 h:7
sweet-ann [11.9K]

Answer:

V = 1077.566 units²

Step-by-step explanation:

Assuming this is a cylinder, the formula is (area of base) × (height)

or (πr²)(h), simply plug-in the given values:

= (π(7)²)(7)

= (153.938)(7)

V = 1077.566 units²

Two sides of a triangle are 8cm and 12cm. Which of the following CANNOT be the measure of the third side,
blondinia [14]

Answer:

4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.

Answer=8

  • (2, 450), (3, 1350), (4, 4050), (5, 12150)

Step-by-step explanation:

The problem statement tells you each observed count is 3 times the last one.

__

Expressed as an exponential function with an initial value of 50 and a growth factor of 3, the formula is ...

  y = (initial value)×(growth factor)^x
