Answer:

40 and 10

Step-by-step explanation:

Let the bigger number = x

Let the smaller number = y

x+y=50

x-y=30

(add the equations)

(x+x)+(y-y)=(50+30)

2x=80

x=40

x+y=50

40+y=50

y=10

A fraction is less than 1. Choose a counterexample that will prove this conjecture false​
Vesnalui [34]

Answer:

1st option

Step-by-step explanation:

Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.

1) \frac{8}{7}  = 1 \frac{1}{7}

This fraction is greater than 1 hence it can prove that the conjecture is false.

2) ½ is lesser than 1 and will not prove that the conjecture is false.

ehidna [41]

Answer:

Year 2034

Step-by-step explanation:

In 2000, 64% had one or more pets

<em>Since decreasing at 1% per year, we can say:</em>

<em>In 2001, 63%</em>

<em>In 2002, 62%</em>

<em>In 2003, 61%</em>

<em>In 2004, 60%</em>

<em>And so on</em>

<em />

To go to 30% from 60% in 2004, we would need to decrease 60 - 30 = 30%, and that will occur after 30 more years. So that would be the year

2004 + 30 = 2034

So, year 2034

HELLP PLEASE IT DUE AT MIDNIGHT TONIGHT

The answer is √3. This is because √3 is already an irrational number and if you multiply it but either -5/9 or add it by 4, the product or sum will not terminate, nor repeat, or is able to turn in to a fraction
