The unit rate is: 2\frac{8}{9} chapters per hour

Step-by-step explanation:

Given

chapters read = 9\frac{3}{4} = \frac{39}{4}

Time = 3\frac{3}{8} = \frac{27}{8}

Unit rate is calculated by dividing the total chapters by total time

So,

Unit\ rate = \frac{\frac{39}{4}}{\frac{27}{8}}\\= \frac{39}{4} * \frac{8}{27}\\= 13 * \frac{2}{9}\\=\frac{26}{9}\\=2\frac{8}{9}

Hence,

The unit rate is: 2\frac{8}{9} chapters per hour

A rectangular dog pen is constructed using a barn wall as one side and 60 meters of fencing for the other three sides. What is t
irinina [24]

Answer:

450 m²

Step-by-step explanation:

Let x = length of rectangle and y = width of the rectangle.

Therefore,

2x + y = 60...............(1)

Making y subject of the formula, we have:

y = 60 - 2x............... (2)

We know area of a rectangle is length * width i.e A = x*y

Let's substitute (60-2x) for y,

A = x * (60-2x)

= 60x - 2(x)²

= -2x² + 60x

\frac{dA}{dx} = -2x^2 + 60x =

-4x + 60 = 0

-4x = -60

x = \frac{-60}{-4} = 15

Let's substitute 15 for x in equation 2, we have:

y = 60 - 2(15)

= 60 - 30

y = 30

Since x = 15 & y = 30, the area would be:

A = xy

A = 15 * 30

A = 450 m²

The maximum area of the dog pen is 450m²
