No, the Triangle Inequality Theorem states that two sides of a triangle always add up to more than the third side. however, 2.1+4 < 7.9. this means that a triangle can't be made

There are 8 roll of carpet each carpet roll i 6 yard longhow long are the 8 roll in feet
vlabodo [156]

The given 8 rolls will have a length of 144 feet or in other words, they will be 144 feet long.

Here, we are given that thee are 8 rolls of carpet and each roll is 6 yards long.

We know that the conversion factor of yards to feet is as follows-

1 yard = 3 feet

Thus, 6 yards = (6 × 3) feet

= 18 feet

⇒ each roll of carpet is 18 feet long

Since there are a total of 8 carpets given, the length of all the 8 rolls will be given as follows-

18 × 8

= 144

Thus, we find that the given 8 rolls will have a length of 144 feet or they will be 144 feet long.

Thepotemich [5.8K]

Answer:

A. 31

B. 5

C. 9/31 or 0.29%

D. 2/31 or 0.06%

E. 0 or unknown

Step-by-step explanation:

A is the addition of all the entries, B is the number of entries that said snakes, C and D are about how many out of the total can give you the corresponding animal, chances are always part/total so for C it's 9/31 and D is 2/31. E is 0 or unknown because there is no "Frog" entries as favorite pet so it must be either 0 or unknown because you don't get the information

Use the product property of exponents to justify that (9^1/2)^2=9
WARRIOR [948]

The rule states that

(a^b)^c = a^{bc}

So, in your case, you have

(9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 &gt; 0
AnnyKZ [126]

we have

x^{2}+2x + 1 > 0

we know that

x^{2}+2x+1=(x+1)^{2}

so

(x+1)^{2}> 0

two solutions

<u>first solution </u>

(x+1)> 0

x > -1

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

-(x+1)> 0

-x-1> 0

-x> 1

x< -1

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number -1
