5/12 is not bigger than 3/7

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.
