Package A is less expensive for Zach to send 250 multimedia texts each month.
<u>Step-by-step explanation:</u>
Given that,
Zach plans to send 250 multimedia texts each month.
Package A charges $0.25 per multimedia text with no monthly fees.
Package B charges $0.20 per multimedia text, but has a $15 monthly fee.
We need to find out which package is less expensive for Zach to add the plan.
<u>The cost of 250 multimedia texts by package A :</u>
⇒ Number of texts × cost per text
⇒ 250 × 0.25
⇒ 62.5
∴ The package A charges $62.5 for 250 multimedia texts.
<u>The cost of 250 multimedia texts by package B :</u>
⇒ (Number of texts × cost per text) + monthly fee
⇒ (250 × 0.20) + 15
⇒ 50 + 15
⇒ 65
∴ The package B charges $65 for 250 multimedia texts.
The Package A charges $62.5 which is less than package B charge of $65.
Hence, package A is less expensive.
Answer:
I think it is 4:3
Step-by-step explanation:
From $960,000 take away $720,000 and you get $240,000 and that $960,000 divide by $240,000 and you get 4 and you do the same with $720,000 and you get 3
Answer:
C .10
Step-by-step explanation:
Answer:
a.No
b.No
c.No
Step-by-step explanation:
a.No,Such set does not exist .A set of natural numbers is N
Every point of this set is an isolated point but no accumulation point
Accumulation point:It is defined as that point a of set Swhich every neighborhood contains infinitely many distinct point of set

Isolated point : it is defined as that point a of set S which neighborhood does not contain any other point of set except itself

Interior point of set :Let
.Then a is called interior point of set when its neighborhood is a subset of set S.

When a set is uncountable then interior point exist it is necessary for interior points existance .
Boundary points :Let
.If every non empty neighborhood of a intersect S and complement of S.
Every member of a set is a boundary point
b.No, such set does not exist .A non empty set with isolated point then the set have no interior points .By definition of interior point and isolated point .For example.set of natural numbers
c.No, Such set does not exist ,for example set of natural every point is an isolated point and boundary point.By definition of boundary point and isolated point
