Pls tell me least to greatest 4.5 and 3.9 and 4.258 and 3.75 and 4.256
Darya [45]
3.75, 3.9, 4.256, 4.258, 4.5

So how do you find out? It is really easy.

First you look the the number, we all know 3 is less then 4 so the 3s go first

Then you look the tenths,  the choices are 3.75 and 3.9.  The tenth 9 and 7, and we all know 7 is less then 9, so 3.75 is the first one, then 3.9.

Now let's look at the 4s.  The choices are 4.5, 4.258, and 4.256.  The tenths are 5, 2, and 2.  2 is less then 5 so they go before 4.5.

Then we look at the hundredth, the choices are 4.256 and 4.258.  Since they have same hundreds, we look at the thousands.  They are 6 and 8.  6 is less then 8 so 4.256 go before 4.258.

(ii) A peacock is sitting on the tree and observes its prey on
Paraphin [41]

Answer:

74.8 m

Step-by-step explanation:

We are given that

\theta=22^{\circ}

Speed of peacock,v=10 km/h

Time,t=1 min 12 sec=60+12=72 s=\frac{72}{3600}=0.02 h

1 hour=3600 s

Distance=vt=10\times 0.02=0.2 km=0.2\times 1000=200 m

Using 1 km=1000 m

We know that

sin\theta=\frac{Perpendicular\;side}{hypotenuse}

Using the formula

sin22=\frac{h}{200}

h=200sin22=200\times 0.374=74.8 m

Hence, the peacock was at height  of 74.8 m on the tree.

Write the equation of the line in slope-intercept form. The line is parallel to y+x=3 and passes through the point (−12, 0).
nataly862011 [7]

y = -x + 3

y = -(x + 12)

y = -x - 12

Which equations are equations for the line shown?
Delvig [45]
First we need to find the slope of the line.

slope = y1-y2/x1-x2 = 4-1/3-(-3) = 3/6 = 1/2

So, the slope is 1/2

Now, we need to find the y-intercept by using the equation y=mx+b

y=mx+b
4=1/2(3)+b
4=3/2+b
-3/2  -3/2
5/2=b

So, the equation is y=1x/2+5/2 which is also C. y-3=1/2(x+1)
