Step-by-step explanation:

-3x + 6y = -27 |-1×|

3x - 6y = 27 |1×|

3x - 6y = 27

Two equations are similar.

Answer:

7 or 8 hours, depending on the answer you're looking for

Step-by-step explanation:

Assuming she wants to make exactly $350, she would need to work for 7 hours making the larger arrangements.

If she works for 8 hours, she can make the most money making the larger arrangements {$400}

The measurement of an angle of a right triangle is 40° and the leg opposite to this angle is 5 cm long. what is the length, in c

8090 [49]

Sine 40 = 5 / hypotenuse
0.64279 = 5 / hypotenuse
hypotenuse = 5 / 0.64279
hypotenuse = 7.7786
tangent (50) = opp / adj
tangent (50) = opposite / 5
1.1918 * 5 = opposite
opposite side = 5.959

A baseball player hits a ball at an angle of 52 degrees and at a height of 4.5 ft. if the ball's initial velocity after being hi

Dafna1 [17]

Answer:

$t\approx 5.865\,s$

Step-by-step explanation:

The motion equations that describe the ball are, respectively:

$x = \left[\left(152\,\frac{ft}{s} \right)\cdot \cos 52^{\circ} \right] \cdot t$

$y = 4.5\,ft + \left[\left(152\,\frac{ft}{s} \right)\cdot \sin 52^{\circ} \right] \cdot t - \frac{1}{2}\cdot \left(32.174\,\frac{ft}{s^{2}} \right) \cdot t^{2}$

The time required for the ball to hit the ground is computed from the second equation. That is to say:

$4.5\,ft + \left[\left(152\,\frac{ft}{s} \right)\cdot \sin 52^{\circ} \right] \cdot t - \frac{1}{2}\cdot \left(32.174\,\frac{m}{s^{2}} \right) \cdot t^{2} = 0$

Given that formula is a second-order polynomial, the roots of the equation are described below:

$t_{1}\approx 5.865\,s$ and $t_{2} \approx -0.048\,s$

Just the first root offers a realistic solution. Then, $t\approx 5.865\,s$ .
