Answer: 0.01429

Step-by-step explanation:

1.429 x 10^{-2}

Now 10^{-2} is just 1/100 or 0.01, because 10^2 is 100

Now we can multiply 1.429 by 0.01 which is 1.429 x 0.01

Or the easy way, we can just place the decimal two places to the left because the power is -2, so 2 places to the left. Moving the decimal to the left makes the number smaller.

So, take 1.492 and move its decimal 2 places to the left

We get 0.01429

Can someone please help me with this
julsineya [31]

Answer:

Step-by-step explanation:

5- There are 2 right-angled triangles and 1 equilateral triangle or you can just say triangles

6- area for a triangle is a=bh(1/2)

so 4×3=12(1/2)=6

and 4×3=12(1/2)=6

In both triangles, they're a=6

7- 4×6=24(1/2)=12

the top flag is a=12

8-12+6+6=24

9- the rectangular flag has an area of 24 since a=bh and the added areas of the triangles are 24. I conclude that these are two ways of finding the area of this rectangular flag.

hope this helps : )

If a building was placed at coordinates (-5,5), what would be the new coordinates if rotated 270° counterclockwise around the or
Brums [2.3K]

The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).

So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).

Hope this Helps!!
