Mathematics
1 answer:
Ilia_Sergeevich [38]3 years ago
5 0

Answer:

Step-by-step explanation:

length = l  ;width = w

Perimeter of rectangle = sum of all sides

                                      =  l + w + l +w

                                      = 2l + 2w

                                       = 2*(l +w )

\text{The scientific notation:}\\\\a\times10^n\\\\1\leq a


a.\\(5\times10^3)\times(3.5\times10^{-1})=(5\times3.5)\times(10^3\times10^{-1})\\\\=15.75\times10^{3+(-1)}=15.75\times10^2=1.575\times10\times10^2\\\\=1.575\times10^{1+2}=\boxed{1.575\times10^3}

b.\\(8\times10^2)\div(4\times10^3)=(8\div4)\times(10^2\div10^3)=2\times10^{2-3}\\\\=\boxed{2\times10^{-1}}

c.\\(6\times10^{-3})^2=6^2\times(10^{-3})^2=36\times10^{-3\cdot2}=36\times10^{-6}=3.6\times10\times10^{-6}\\\\=3.6\times10^{1+(-6)}=\boxed{3.6\times10^{-5}}

Used:\\\\a^n\times a^m=a^{n+m}\\\\a^n\div a^m=a^{n-m}\\\\(a^n)^m=a^{n\cdot m}

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than a certain number of inches
Georgia [21]
So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2

use the distributive property to remove parentheses. Simplify your answer as much as possible. 1/2(4y+7)
Anna007 [38]
1/2(4y+7)

Use the distributive property. a(b+c)= ab+ac 

1/2*4y= 2y

1/2*7= 3.5

2y+3.5 <---- simplified expression

I hope this helps!
