Answer:

x = 76

Step-by-step explanation:

First, distribute -4:

-4x + 104 = -200

Isolate x:

-4x = -200 - 104 = -304

x = -304/-4 = 76

What is the maximum height of the basketball when the player passes the ball to someone? Initially, the ball moves at a speed of

ZanzabumX [31]

Answer with explanation:

Since the motion of the ball is projectile motion we shall use the equations for projectile motion.

The maximum height achieved by the projectile is given by

$h_{max}=\frac{v_{o}^{2}sin^{2}(\theta )}{2g}$

Applying the values we get

$h_{max}=\frac{12^{2}\times sin^{2}(45)}{2\times 9.81}\\\\h_{max}=3.669m$

The range of the projectile is given by

$R=\frac{v_{o}^{2}sin(2\theta )}{2g}$

Applying values we get

$R=\frac{12^{2}\times sin(2\times 45 )}{2\times 9.81}\\\\R=7.339m$

thus the maximum horizontal distance reached by the ball equals 7.339 meters after which it bounces thus a person standing 8 meters away will not be able to catch it.

(The height of the players is not taken into account since no info is given about their height.)

A shopkeeper makes a profit of 15% by selling a book for $230. What is the cost price and the actual profit?

lys-0071 [83]

Answer:

Cost price = 200

Profit = 230-200 = 30

Step-by-step explanation:

x + 15/100x = 230

x + 3/20x = 230

20x + 3x = 4600

23x = 4600

x = 200

What is equivalent to n – 4.6n – 3.3n + 2.8n

Ahat [919]

Answer:

4.1n

Step-by-step explanation:

Let's simplify step-by-step.

n−4.6n−3.3n+2.8n

=n+−4.6n+−3.3n+2.8n

Combine Like Terms:

=n+−4.6n+−3.3n+2.8n

=(n+−4.6n+−3.3n+2.8n)

=−4.1n

Sally begins hiking at an elevation of 224 ft then she descends 131 ft and climbs 67 feet higher than her current position she t

Temka [501]

Answer:

Sally ends at 3 feet below zero point.

Step-by-step explanation:

Let be $h$ the height with respect to zero point, which is represented by the following sum:

$h = \Sigma_{i=1}^{n} h_{i}$

Where:

$h_{i}$ - i-th travelled height, measured in feet.

In addition, positive sign means ascension, whereas negative sign means descent.

The statement can be translated into the following mathematical identity:

$h = h_{1}+h_{2}+h_{3}+h_{4}$

$h = 224\,ft+(-131\,ft)+67\,ft -163\,ft$

$h = -3\,ft$

Sally ends at 3 feet below zero point.
