How to order fractions

1 answer:

5 0

The easiest way for me to order fractions is by decimal.
Ex: 1/2, 15/5/, 1/4
So you have to turn them into decimal form. Ex: 0.5, 3, 0.25
There are to ways to order them(greatest to least or least to greatest)
Greatest to least is 2, 0.5, 0.25 because you are ordering them to the greater numbers. For least to greatest you would just put the opposite.
Hope it helps :]

A particle moves along the x-axis so that at time t its position is given by s(t) = (t + 1)(t - 3)3, t > 0. /p>For what va

Given the position function, the velocity function is obtained by taking the derivative:

$s(t)=(t+1)(t-3)^3\implies v(t)=(t-3)^3+3(t+1)(t-3)^2$

The velocity is increasing its own derivative is positive, so we also have to find the acceleration by taking another derivative:

$a(t)=4(t-3)^3+3(t-3)^2+6(t+1)(t-3)$

To find when $a(t)>0$ , we first need to know where $a(t)=0$ :

$4(t-3)^3+3(t-3)^2+6(t+1)(t-3)=(t-3)\bigg(4(t-3)^2+3(t-3)+6(t+1)\bigg)=(t-3)(4t^2-15t+33)=0$

The quadratic factor is always positive (its discriminant is negative), which leaves one solution at $t=3$ . To either side of $t=3$ , we have, for instance,

$a(2)=-12$

$a(4)=36>0$

which indicates that $v(t)$ is increasing for $t>3$ , making the answer A.

Paolo helped in the community garden for 2 3/4 hours this week. This was 1 5/6 equal length shift, because Paolo stopped early o

12345 [234]

If 2+3/4 hours is equal to 1+5/5 equal length shift then the single shift is 1.5 hours long.

Given that Paolo helped in the community garden for 2 +3/4 hours this week which is 1+5/6 times length shift.

We are required to find the length of a single shift.

First we have to find the proper fraction of the given mixed fractions.

Fraction is combination of numerator and denominator.The number that is present above the division sign is known as numerator and the number that is present below the division sign is known as denominator.

2+3/4=(8+3)/4=11/4

1+5/6=(6+5)/6=11/6

let the length of a shift is x hours.So,

11/4=11*x/6

11/4=11/6 x

66/44=x

x=3/2

x=1.5 hours.

Hence if 2+3/4 hours is equal to 1+5/5 equal length shift then the single shift is 1.5 hours long.

What two-dimensional cross section do a cube and a square pyramid have in common?

TEA [102]

Answer:

D. Square

Step-by-step explanation:

Neither a Cube or a Square pyramid have an ellipse, hexagon or octagon on them anywhere, and a cube doesn't have a triangle on it, so the only thing out of these choices that these even have in common is a square.

I hope this explains it!
