The length of a rectangle envelope is 2 1/2 times its width. A plastic band surrounds the front and back of the envelope to secu

Andreas93 [3]

<u>Answer</u>:

Length of the envelope = 14

Width of the envelope = 5.6

<u>Step-by-step explanation:</u>

Let the width of the rectangle be x

Then the length of the rectangle will be $2\frac{1}{2} \times x$

Also the length of the plastic band to cover the front and back of the envolpe = $39\frac{3}{8}$

To cover one side th band required is

=> $\frac{39\frac{3}{8}}{2}$

=> $\frac{\frac{315}{8}}{2}$

=> ${\frac{315}{16}$

=>39.4

We know that the perimeter of the rectangle is

=> 2( L + B) = ${\frac{39.4}{2}$

=> 2( $2\frac{1}{2} \times x + x$ ) = 19.7

=> 2( $\frac{7}{2}x) = 19.7$

=> $3.5x = 19.7$

=> $x = \frac{19.7}{3.5}$

=> $x = 5.6$

Now length of the envelope =

=> $2\frac{1}{2} \times x$

=> $2.5 \times 5.6$

=> 14

Need help with the question in the picture learned awhile ago and forget!

xxTIMURxx [149]

Answer:

-i

Step-by-step explanation:

i^15

Divide the exponent by 4

15/4 = 3 r 3

Take the remainder and use as the exponent

i^3

We know that i^2 = -1

i^3 = i^2 *i

i^3 = -1*i

-i

I think of number I add 14 to the number and multiply the result by 3 if my final answer is 51 what number did I think of

erma4kov [3.2K]

Answer:

-1

Explanation:

Let the number be x.

Then the equation will be:

3(x+18) = 51

=> 3x + 54 = 51

=> 3x = 51 - 54

=> 3x = -3

=> x = -3/3

=> x = -1

So, the number you thought of is -1.
