You got 2 types of data $ and %!
Line them up accordingly and cross multiply.

16% is to $38 as
100% is to $x

X= 38•100/16= $237.5 the price before discount

Answer: The price of the supplies before the discount is $237.5.

Step-by-step explanation: Given that a discount of 16% saved Jackie $38 on office supplies.

We are to find the price of the supplies before the discount.

Let $x be the price of the supplies before the discount.

Then, according to the given information, we have

$16\%\times x=38\\\\\\\Rightarrow \dfrac{16}{100}\times x=38\\\\\Rightarrow 16x=3800\\\\\Rightarrow x=\dfrac{3800}{16}\\\\\Rightarrow x=237.5.$

Thus, the price of the supplies before the discount is $237.5.

A ball is thrown upward from the top of a 192-foot-high building. The ball is 240 feet above ground level after 1 second, and it

Answer:

The equation of this function is $h = -16\cdot t^{2}+64\cdot t+192$ .

Step-by-step explanation:

From Mechanical Physics we must remember that height reached by the ball as a function of time is a quadratic function if and only if ball is uniformly accelerated by gravity and viscous forces and Earth's rotation effects can be neglected. After assuming those considerations as true, the standard form of the quadratic function is:

$h = a\cdot t^{2}+b\cdot t + c$ (Eq. 1)

Where:

$t$ - Time, measured in seconds.

$h$ - Height of the ball, measured in feet.

$a$ - Second order coefficient, measured in feet per square second.

$b$ - First order coefficient, measured in feet per second.

$c$ - Zero order coefficient, measured in feet.

From Algebra, we can obtain a quadratic function by know three distinct points and solving the resulting system of linear equations:

$A(t, h)= (0\,s,192\,ft)$

$c = 192\,ft$ (Eq. 2)

$B(t,h) = (1\,s,240\,ft)$

$a+b+c = 240\,ft$ (Eq. 3)

$C(t,h) =(6\,s,0\,ft)$

$36\cdot a + 6\cdot b + c = 0$ (Eq. 4)

By Algebraic methods, we get this unique solution:

$a = -16\,\frac{ft}{s^{2}}$ , $b = 64\,\frac{ft}{s}$ , $c = 192\,ft$

The equation of this function is $h = -16\cdot t^{2}+64\cdot t+192$ .

Brandon needs $480 to buy a TV and stereo system for his room. He received $60 in cash for birthday presents. He plans to save $

Monica [59]

Answer:

14 weeks till he has $480

Step-by-step explanation:

He needs $480

He has $60

He has to earn the rest over the span of the next few weeks, which is $30 for an unknown number of weeks.

Let the unknown number be x in our equation

What he needs to buy the TV and Stereo system is $480 which is our total

The $60 dollars he received is a complete variable

hence we can say,<em> 30x+60=480</em>

<u>This is our equation</u> but it isn't simplified.

first, divide everything by 10(it is a common divisor)

<em>3x+6=48</em>

<em>subtract</em> 6 which is complete from the total

3x=42

Make x the subject and divide both sides by 3

x=14

so the unknown number of weeks is 14.
