If you’re solving for x, it’s x= 17/2 - y
If you’re solving for y, it’s y= 17/2 - x

A box of cereal states that they are 72 cal in a 3/4 cup serving. What is the calories per cup? How many calories are there in 4

Illusion [34]

Answer:

The answer is simple, you have 72 calories as 3/4 of a cup. So you calculate 1/4 of a cup by dividing 72 by 3. We get 24, now we get a total of 96 calories in one cup. Now we have 96x4 which is 384.

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:

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