If Herschel walker can sprint 40 meters in 4.35 seconds, how many miles per hour is he running? Round to the nearest tenth
-BARSIC- [3]

Answer:

B) 20.6 mi/hr

Step-by-step explanation:

To solve this, we need to first convert 40 meters to mile, then convert 4.35 seconds to hour, then solve by proportion.

converting 40 meters to mile;

1 mile = 1609.344 meter

x       = 40 meters

1609.344x = 40

x = 40/1609.344

x =0.02485 mile

Then converting seconds to hour

1 hour = 3600 seconds

 y      = 4.35 seconds

3600 y = 4.35

y=4.35/3600

y =0.00121  hour

Using proportion to solve the question

Let n be the number he runs miles per hour

0.02485 mile = 0.00121  hour

  n                   = 1    hour

cross-multiply

0.00121  n =   0.02485

Divide both-side by 0.00121

0.00121  n/0.00121  =   0.02485/0.00121

n ≈ 20.6 mile/hour

Therefore, he is running 20.6 mi/hr

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
lora16 [44]

Answer:

The maximum amount of profit the company can make is $854.08

Step-by-step explanation:

Let

x ----> the selling price of each widget

y ---> the amount of profit

we have

y=-3x^{2} +155x-1148

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

so

The y-coordinate of the vertex represent  the maximum amount of profit the company can make

using a graphing tool

Find out the vertex of the quadratic equation

The vertex is the point (25.83,854.08)

see the attached figure

The y-coordinate of the vertex is 854.08

therefore

The maximum amount of profit the company can make is $854.08
