You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.  

\frac{5}{12} \frac{3}{7}

Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction. 
\frac{5}{12} \frac{3}{7}
5 * 7 = 35, 3 * 12 = 36
So \frac{3}{7} is bigger.

A rancher wants to fence in an area of 1500000 square feet in a rectangular field and then divide it in half with a fence down t
VLD [36.1K]

Answer:

6000 ft

Step-by-step explanation:

Let length of rectangular field=x

Breadth of rectangular field=y

Area of rectangular field=1500000 square ft

Area of rectangular field=l\times b

Area of rectangular field=x\time y

1500000=xy

y=\frac{1500000}{x}

Fencing used ,P(x)=x+x+y+y+y=2x+3y

Substitute the value of y

P(x)=2x+3(\frac{1500000}{x})

P(x)=2x+\frac{4500000}{x}

Differentiate w.r.t x

P'(x)=2-\frac{4500000}{x^2}

Using formula:\frac{dx^n}{dx}=nx^{n-1}

P'(x)=0

2-\frac{4500000}{x^2}=0

\frac{4500000}{x^2}=2

x^2=\frac{4500000}{2}=2250000

x=\sqrt{2250000}=1500

It is always positive because length is always positive.

Again differentiate w.r.t x

P''(x)=\frac{9000000}{x^3}

Substitute x=1500

P''(1500)=\frac{9000000}{(1500)^3}>0

Hence, fencing is minimum at x=1 500

Substitute x=1 500

y=\frac{1500000}{1500}=1000

Length of rectangular field=1500 ft

Breadth of rectangular field=1000 ft

Substitute the values

Shortest length of fence used=2(1500)+3(1000)=6000 ft

Hence, the shortest length of fence that the rancher can used=6000 ft

Kendell made 2/5 of a necklace in 1/9 of an hour. How many necklacws can she make in one hour?
Ivahew [28]

Answer:

18/5 or 36 necklace

Step-by-step explanation:

kendell made 2/5 necklace in 1/9 hours

how many will she make in 1 hour

hmmm?

2/5 = 1/9

x = 1

2/5 × 1 = 1/9x

x = 2/5 ÷ 1/9

x = 2/5 × 9/1

x = 18/5

x = 3.6necklace

Answer:

"Acceleration" means any change in the speed or direction of motion ... speeding up, slowing down, or turning.  So . . .

-- The distance traveled in a certain time may increase or decrease.

-- The displacement covered in a certain time may increase or decrease.

-- The speed of the object may increase or decrease.

-- The velocity of the object (speed/direction) will change.
