S : O

7 : 6 = 161 : ?

161 / 7 = 23

6 * 23 = 138

1) <span>-16a+3+7a-6 = -9a - 3

2) </span><span>14x+8y+12y-20x = 20y - 6x

4) </span>(9x+2y-8) - (12x+11 = -3x + 2y - 19

A ladder leaning against a wall forms a triangle and exterior angles with the wall and the ground. What is the measure of exteri

Murrr4er [49]

Yo sup??

we know that the sum of all the angles of a triangle is 180

therefore

11x+7x+90=180

18x=90

x=5

exterior angle formed on the ground=180-11x

=180-55

=125

Hope this helps

Suppose the voltage in an electrical circuit varies with time according to the formula V(t) = 40 sin(t) for t in the interval [0

grigory [225]

The numerical value of the mean voltage is 25.47 V

To find the numerical value of the mean voltage, V of V(t) = 40 sin(t), we integrate V(t) with respect to t over the interval [0.π]

So,

$V = \frac{1}{\pi } \int\limits^\pi _0 {V(t)} \, dt \\V = \frac{1}{\pi } \int\limits^\pi _0 {40sint} \, dt \\V = \frac{1}{\pi } [-40cost]_{0}{\pi } \\V = \frac{1}{\pi } -[40cos\pi - 40cos0]\\\\V = \frac{1}{\pi } (-[40 X (-1) - 40 X 1})\\V = -\frac{1}{\pi } [-40 - 40]\\V = \frac{80}{\pi } \\V = 25.465 V$

V ≅ 25.47 V

So, the numerical value of the mean voltage is 25.47 V
