What are the side lengths of the equilateral triangle?

Alchen [17]

$5x + (6x - 5) + (3x + 10) = 360$

$5x + 6x - 5 + 3x + 10 = 360$

$11x - 5 + 3x + 10 = 360$

$14x + 5 = 360$

$14x = 360 - 5$

$14x = 355$

$x = 25.36$

$5x = 5 \times 25.36 = 126.8$

$6x - 5 = 6 \times 25.36 - 5 = 147.16$

$3x + 10 = 3 \times 25.36 + 10 = 86.08$

No work needed, just the answer!

Answer:

The answer to your question is: x = - 102

Step-by-step explanation:

$- \frac{x}{6} + 1 = 18$

$- \frac{x}{6} = 18 - 1$

$- \frac{x}{6} = 17$

-x = 17 x 6

-x = 102

x = -102

A national survey of small-business owners was conducted to determine the challenges for growth for their businesses. The top ch

krek1111 [17]

Answer:

A) 12/37

B) 12/46

C) 25/54

D) 29/100

Step-by-step explanation:

Let event A = small-business owner selected economy,

event B = small-business owner selected finding qualified workers,

Thus, probabilities;

P(A)=46/100

P(B)=37/100

P(A∩B)=12/100

A) P(A ∩ B)/P(B) = (12/100)/(37/100) = 12/37

B) P(A∩B)/P(A) = (12/100)/(46/100)= 12/46

C) P(B∩A')= P(B) − P(A∩B) =

37/100 - 12/100 =25/100

P(B∩A')/P(A') =

(25/100)/(1-46/100) = 25/54

D) Using inclusion-exclusion principle;

P(A∪B) = P(A)+P(B)−P(A∩B)=

46/100 + 37/100 - 12/100 = 71/100

Hence, the probability that the owner believes neither that the economy is a challenge for growth nor that finding qualified workers is a challenge for growth is;

P( A' ∩ B') = 1 − P(A∪B)= 1− (71/100)= 29/100
