Answer:

The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is $\mathbf{Speed=\frac{100}{20} }$

Step-by-step explanation:

We are given:

Distance = 100 m

Time = 20 s

We need to find:

Speed

The formula used is: $Speed=\frac{Distance}{Time}$

Putting values and finding the expression

$Speed=\frac{Distance}{Time}\\Speed=\frac{100}{20}$

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is $\mathbf{Speed=\frac{100}{20} }$

A box is contructed out of two different types of metal. the metal for the top and bottom, which are both square, costs $3 per s

zysi [14]

Let x ft be the length of the base square and y ft be the height of the box.

The volume of the box is

$V=x\cdot x\cdot y\ ft^3.$

Since the box has a volume of 15 cubic feet, then

$x^2y=15,\\ \\y=\dfrac{15}{x^2}.$

You need to construct two squares from the metal that cost $3 per square foot.

The area of each square is $x^2\ ft^2$ and the total cost for these two squares is $2\cdot x^2\cdot 3=6x^2.$

The area of each side face is $x\cdot y=x\cdot \dfrac{15}{x^2}=\dfrac{15}{x}.$ Then the total cost for sides is $4\cdot \dfrac{15}{x}\cdot 10=\dfrac{600}{x}.$
