Answer:

The total cost charged by the two companies will be the same for 10 square yards of carpeting .

Step-by-step explanation:

Let us assume that the number of square yards for carpeting  used be x.

Let us assume that the total cost of the  charged by the companies be y.

As given

Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100.

Than the equation becomes

y = 22x + 100

As given

City Carpets charges $25 per square yard for the same carpeting, and an additional installation fee of $70.

Than the equation becomes

y = 25x + 70

Than the two equations are

y = 22x + 100 and y = 25x + 70

Than compare the two equations are

22x + 100 = 25x + 70  

25x - 22x = 100 - 70

3x = 30

x = \frac{30}{3}

x = 10 square yards .

Therefore the total cost charged by the two companies will be the same for 10 square yards of carpeting .

Prove cotA+cotB+cotC &gt;= square root of 3
Zigmanuir [339]
<span>Given cotA + cotB + cotC = sqrt3
to prove triangle ABC is equilateral 
we prove this by assuming ABC to be equialteral and establishing the truth 
of the statement cotA + cotB + cotC =sqrt3 

since ABC is equialteral angleA=angleB=angleC=60 degrees 
cotA=cotB=CotC = cot60= 1/sqrt3 
therefore cotA + cotB + cotC = 1/sqrt3 + 1/sqrt3 + 1/sqrt3 
=3/sqrt3 
=sqrt3 which is equal to the RHS ( right hand side) of the expression 
hence our assumption that ABC is equilateral is true</span>

Sean says that to add a number to -100 and still have -100 is to add zero.candice says that she can add two numbers to -100 and
elena-s [515]
Both are right b/c like sean says you can add zero and itll still be -100 but candice is also right b/c because you can add any # to that -100 but you can also add a negative # to get it back to -100. for example: -100+23= -77 but if you also add a negative 23 it would be right back to -100.
