Artemis has six boards cut in various lengths as shown she wants to use three of them to frame a triangular window in her new cl

SOVA2 [1]

Question:

The sizes of the length of the boards are as follows;

Number of boards with length, 2 ft = 2

Number of boards with length, 6 ft = 2

Number of boards with length, 9 ft = 2.

Answer:

The answer to the question is;

The number of unique triangles Artemis can make with the lengths she has is four.

Step-by-step explanation:

The sizes of the six boards are as follows

2 by 9 ft length boards

2 by 6 ft length boards

2 by 2 ft length boards

Therefore since the sum of the lengths of the other two sides of a triangle must be greater than the third side, we have the following possible unique triangles

9 ft by 9 ft by 6 ft ........(1)

9 ft by 9 ft by 2 ft ........(2)

6 ft by 6 ft by 9 ft ........(3)

6 ft by 6 ft by 2 ft ........(4)

Therefore we have four unique triangles.

Which is the intersection of the sets {2,3,5,7} and {2,5,11,13}?

pishuonlain [190]

ANSWER

The set of the intersection of { $2,3,5,7$ } and { $2,5,11,13$ } is

{ $2,5$ }

EXPLANATION

Let $A=$ { $2,3,5,7$ }

and

$B=$ { $2,5,11,13$ }.

The intersection of the two sets are the elements that are in both set A and set B.

The elements that are common to both sets are 2 and 5. So, we write;

$A \cap B=$ { $2,5$ }

Therefore the correct answer is C

0.66666667 as a fraction

Ierofanga [76]

Answer:

__________________________________________

The correct answer is: " $\frac{2}{3}$ " .

__________________________________________

Note: Let's assume that this given decimal value is really:

"0.66666666666666666....." ;

(non-terminating; but repeating the singing digit, "7" ; yet rounded to:

" 0.66666667 " ;

then: " 0.666... " = $\frac{666}{999}$ ;

= (666 ÷ 111) / (999 ÷ 111) ;

= 6/9 ;

= (6÷3)/(9÷3) ;

= 2/3 ;

= " $\frac{2}{3}$ "

→ which is our answer.

____________________________________________

Or: " 0.6666... " = 666 ÷ 999 = ? ;

using calculator :

= 0.66666667 ;

→ which is the "rounded off" number of "0.6666..." ;

— (infinitely repeating) ;

→ So 666 ÷ 999 =

→ " $\frac{666}{999}$ " ;

= " $\frac{2}{3}$ " ;

→ Either use a "fraction calculator" ;

or simplify as aforementioned.

Hope this answer is helpful to you!

Answer: n=4

Step-by-step explanation:

$\left(-9\right)-9n=\left(-45\right)$

add 9 to both sides

$-9-9n+9=-45+9$

$-9n=-36$

divide both sides by -9

$n=4$
