Answer:

Yes, 1/2 is a irrational number

Step-by-step explanation:

This is the answer because (Google research):

A number is rational if we can write it as a fraction where the numerator and denominator are both integers. However, numbers like 1/2, 46485928/2628242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

Hope this helps!

Jayanta is raising money for the? homeless, and discovers each church group requires 2 hr of letter writing and 1 hr of? follow-

boyakko [2]

Answer:

Jayanta needs 2 labor union groups and 8 church groups.

Step-by-step explanation:

Let c denotes churches .

Let l denotes labor unions.

We know that Jayanta can only spend 20 hours letter writing and 14 hour of follow-up.

So, equations becomes:

$2c+2l=20$

$c+3l=14$

And total money raised can be shown by = $150c+175l$

We have to maximize $150c+175l$ keeping in mind that $2c+2l \leq 20$ and $c+3l \leq 14$

We will solve the two equations: $2c+2l=20$ and $c+3l=14$

We get l = 2 and c = 8

And total money raised is $150\times8 + 175\times2$ = $1200+350=1550$ dollars.

Hence, Jayanta needs 2 labor union groups and 8 church groups.
