Given the equation p = 3(s + 100)/4 

Where,

p = profit made

s = sales 

Solving for s from the given equation

p = 3(s + 100)/4

Multiply both sides by 4

4p = 3(s + 100)

4p = 3s + 300

Subtract 300 from both sides of the equation

4p – 300 = 3s

Same as, 3s = 4p – 300

s = (4p – 300)/3 

OR, s = 4p/3 – 100 

If any of these two is in the options, it’s the right answer.

marta [7]

Answer:

Step-by-step explanation:

The position function is

s(t)=-2.7t^2+50t+6.5 and if we are looking for the time(s) that the ball is 10 feet above the surface of the moon, we sub in a 10 for s(t) and solve for t:

10=-2.7t^2+50t+6.5 and

0=-2.7t^2+50t-3.5 and factor that however you are currently factoring quadratics in class to get

t = .07 sec and t = 18.45 sec

There are 2 times that the ball passes 10 feet above the surface of the moon, once going up (.07 sec) and then again coming down (18.45 sec).

For part B, we are looking for the time that the ball lands on the surface of the moon. Set the height equal to 0 because the height of something ON the ground is 0:

0=-2.7t^2+50t+6.5 and factor that to get

t = -.129 sec and t = 18.65 sec

Since time can NEVER be negative, we know that it takes 18.65 seconds after launch for the ball to land on the surface of the moon.

Which of the following options have the same value as 60\%60%60, percent of 949494?
garri49 [273]
<h2>Answer:</h2>

The correct options are:

        Choice A

       Choice C

and  Choice E

<h2>Step-by-step explanation:</h2>

We are asked to find the value of:

                   60% of 94

We know that: it is represented as:

  60\%\ of\ 94=\dfrac{60}{100}\times 94\\\\\\=0.6\times 94

Choice A)

           0.06\cdot 940

We know that:

    0.6\times 94 could also be written as:

0.06\times 940

Since we multiplied and divide by 10 such that:

=0.6\times 94\times \dfrac{10}{10}\\\\\\=\dfrac{0.6}{10}\times (94\times 10)\\\\\\=0.06\times 940

Hence, option: A is correct.

Choice B)

                  0.6\cdot 940

This option is incorrect.

Since by choice A we get that the correct expression is:   0.06\cdot 940

Choice C)

             We get:

        \dfrac{3}{5}\cdot 94

This option is correct.

Since,

60\%\ of 94\ is:\\\\\\=\dfrac{60}{100}\cdot 94\\\\\\=\dfrac{3}{5}\cdot 94

Choice D)

                             60\cdot 94

This option is incorrect because the actual expression is:

         0.6\cdot 94

Choice E)

               [/tex]\dfrac{60}{100}\cdot 94[tex]

This is the correct expression.

cost per liter = 2995 / 3 L
cost per liter = 998 per liter of milk

at second shop the two liters of milk cost 1595
 cost per liter = cost / volume
cost per liter = 1595 / 2 L
cost per liter = 797.5 per liter of milk
