• Convert 3 hours into minutes: 3 x 60(minutes in an hour) = 180 minutes
• Divide to see how many times 30 minutes goes into 180: 180 ÷ 30 = 6
• Multiply: 25 x 6 = 150 

So, Jenna can read 150 pages of a book in 3 hours. Hope this helps! :D

A farmer Has 900 yards of fencing to enclose a rectangular pasture for her goats. Since one side of the pasture borders a river,
horsena [70]

Answer:

Length, l=450 yards

Width, b=225 yards

Step-by-step explanation:

Let the long side be x and since the length is twice the width, then the width is half of that length hence 0.5x. Since we only have three parts to fence as one long side doesn't require fencing, then the perimeter will be given by x+0.5x+0.5x=2x=900 yards

X=900/2=450 yards for long side.

The short side is 0.5x hence 0.5*450=225 yards

In conclusion, the long side is 450 yards while short side is 225 yards.

A company that manufactures hair ribbons knows that the number of ribbons it can sell each week, x, is related to the price p pe
mel-nik [20]

Given:

The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:

x=1000-100p

To find:

The selling price if the company wants the weekly revenue to be $1,600.

Solution:

We know that the revenue is the product of quantity and price.

R=xp

R=(1000-100p)p

R=1000p-100p^2

We need to find the value of p when the value of R is $1600.

1600=1000p-100p^2

1600-1000p+100p^2=0

100(16-10p+p^2)=0

Divide both sides by 100.

p^2-10p+16=0

Splitting the middle term, we get

p^2-8p-2p+16=0

p(p-8)-2(p-8)=0

(p-8)(p-2)=0

Using zero product property, we get

p-8=0 or p-2=0

p=8 or p=2

Therefore, the smaller value of p is $2 and the larger value of p is $8.
