9) If m/1 = 45° and 21 and 22 are complementary angles. Find m22.

Allisa [31]

❄ Hi there,

keeping in mind that the sum of complementary angles is 90°,

set up an equation, letting $\angle2$ be x –

$\triangleright \ \sf{\angle1+x=90}$ {and we know that $\boxed{\angle1=45}$ }

$\triangleright \ \sf{45+x=90}$

$\triangleright \ \sf{x=90-45}$

$\triangleright \ \sf{x=45}$

$\triangleright \ \sf{\angle2=45\textdegree}$

__________

Keeping in mind that a right angle is 90°,

set up an equation, letting $\angle1$ be x:

$\triangleright \ \sf{x+\angle2=90}$ {and we know that $\boxed{\angle2=63}$ }

$\triangleright \ \sf{x+63=90}$

$\triangleright \ \sf{x=27}$

$\triangleright \ \sf{\angle1=47\textdegree}$

Maria throws a softball straight up into the air with an initial velocity of 50 ft/sec. The ball leaves her hand when it is exac

Nataly_w [17]

Answer:

The equation that models the situation is $s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$ .

Step-by-step explanation:

Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:

$v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})$ (1)

Where:

$s_{o}$ , $s_{f}$ - Initial and final position of the softball, measured in feet.

$a$ - Acceleration, measured in meters per square second.

$v_{o}$ , $v_{f}$ - Initial and final velocities of the softball, measured in feet per second.

If we know that $v_{o} = 50\,\frac{ft}{s}$ , $a = -32.174\,\frac{m}{s^{2}}$ and $s_{o} = 4\,ft$ , then the equation that models the situation is:

$v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)$

Then, we clear the final position of the softball:

$-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4$

$s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$

The equation that models the situation is $s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$ .

One fifth of one number and one fourth of a number are added, the result is 29. What is the original number?

Morgarella [4.7K]

Answer:

$\dfrac{580}{9}$

Step-by-step explanation:

$\dfrac{1}{5}x + \dfrac{1}{4}x = 29$

$\dfrac{4}{20}x + \dfrac{5}{20}x = 29$

$\dfrac{9}{20}x = 29$

$x = 29 \times \dfrac{20}{9}$

$x = \dfrac{580}{9}$

Answer: $\dfrac{580}{9}$
