Answer:

Step-by-step explanation:

B = 180 - 50 - 35 = 115 degrees

By the law of sines,

c=\frac{13\sin 35^{\circ}}{\sin 115^{\crc}}

And a=\frac{13\sin 50^{\circ}}{\sin 115^{\circ}}

Answer:

Answer:

11 feet

Step-by-step explanation:

Area formed by the watery pattern is 379.94 square feet.

Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.

Area of a circle is given as:

\begin{gathered}Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11\end{gathered}

Area=πr

2

379.94=πr

2

r

2

=

π

379.94

Using pi equal to 3.14, we get

r

2

=121

r=11

This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.

Step-by-step explanation:

im not sure if that is correct

comment if wrong

I don't understand how to do question c, d and f. Can someone please help me?
noname [10]

Answer:

Step-by-step explanation:

As with any equation involving fractions, you can multiply the equation by the least common denominator to eliminate fractions. Then solve in the usual way.

c) 1/a +b = c

  1 +ab = ac . . . . multiply by a

  1 = ac -ab . . . . subtract ab

  1 = a(c -b) . . . . . factor out a

  1/(c -b) = a . . . . divide by the coefficient of a

__

d) (a-b)/(b-a) = 1

  a -b = b -a . . . . . multiply by b-a

 2a = 2b . . . . . . . . add a+b

  a = b . . . . . . . . . . divide by the coefficient of a

Please be aware that this makes the original equation become 0/0 = 1. This is why a=b is not an allowed condition for this equation. As written, it reduces to -1 = 1, which is false. One could say <em>there is no solution</em>.

__

f) bc +ac = ab . . . . . multiply by abc

  bc = ab -ac . . . . . . subtract ac

  bc = a(b -c) . . . . . . factor out a

  bc/(b -c) = a . . . . . . divide by the coefficient of a
