Which number produces an irrational number when multiplied by 1/2

Mathematics
1 answer:
Ludmilka [50]3 years ago
8 0

Quick answer

Any irrational number. I can't think of any exception to this statement.

sqrt(5) is irrational.  1/2 * sqrt(5) is still irrational.

-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational

2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.

1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.

Conclusion

There are no exceptions to this.  All irrational numbers produce irrationals when multiplied by 1/2

nekit [7.7K]

Answer:

$43.20

Step-by-step explanation:

A swimsuit that originally cost $90 before any discount is on sale for 20% off.

X = price of swimsuit

X = 90

20% off = 90 * 0.8 = 72

The swimsuit is then put on clearance for an additional 40 % off the sale price.

72 * 0.6 = 43.2

what is the final price?

13.) Solve for M<br> 14.) Solve for A<br> 17.) Solve for H
brilliants [131]

Answer:

See Below (Isolate the variables)

Step-by-step explanation:

13) d = 4AM solve for M

Divide both sides by 4A

\frac{d= 4AM}{4A}

\frac{d}{4A} = M

14) \frac{A}{6} = f+h  solve for A

Multiply both sides by 6

A = 6( f+h)

15) h - m = qb solve for H

Add m to both sides

h - m = qb

  + m   +m

h = qb + m

2A+2B=17&#10;&#10;2A+2(A+0.5)=17&#10;&#10;2A+2A+1=17&#10;&#10;4A=16&#10;&#10;A=4
