hoa [83]2 years ago
5 0

Answer:

- 14x - 9y = 6

Step-by-step explanation:

- 7x - y = 0 → (1)

7x + 8y = - 6 → (2)

Subtracting (2) from (1) term by term

- 7x - 7x - y - 8y = 0 - (- 6)

- 14x - 9y = 0 + 6

- 14x - 9y = 6

lys-0071 [83]

Answer: -\frac{8}{77}

Step-by-step explanation:

\frac{\frac{4}{7} }{-\frac{11}{2} }

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}

\frac{4}{7}*-\frac{2}{11}

Find c and round to the nearest tenth. thank you in advance
PSYCHO15rus [73]

Answer and Step-by-step explanation:

90ft = a

55ft = b

50ft = c

Plug into equation.

50^{2}  = 90^{2}  + 55^{2}  - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4

29.4° is the answer.

nordsb [41]

Answer:

12 units

Step-by-step explanation:

Allow me to revise your question for a better understanding and I hope it will fit the original one.  

The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.

Here is my answer:

Given:

The area: 72 units squared.

The base: 6 units

As we know that the area of the parallelogram is represented by below formula:

A = b*h where h is the height and b is the base

In this situation, we know:

72 = 6*h

<=> h = 12

So the missing height is 12 units
