Answer:

L = 97, w = 27

Step-by-step explanation:

The perimeter formula is P = 2L + 2w.  We have too many unknowns simply to plug in, so we have to find a way to identify one in terms of the other.  The statement is that the length is 16 feet more than 3 times the width, so the length is in terms of the width and can be identified as

L = 3w + 16

and the width, then, is just w.  Now we can fill in those 2 values, both in terms of w, and set it to equal the perimeter value we were given of 248:

2(3w + 16) + 2w = 248 and

6w + 32 + 2w = 248 and

8w + 32 = 248 and

8w = 216 so

w = 27

That means that the width is 27.  Use that value of w now to find the length where

L = 3w + 16.

L = 3(27) + 16 and

L = 97

Answer:

Concept: Mathematical Derivation

  1. We are given x^2 +6x+2x+12
  2. Hence we simplify: x^2 + 8x +12
  3. Now we factor: (x+2)(x+6)
  4. By mathematical logic we now proved that the roots are x=-2 and x=-6

What is the store paid $75 for a clarinet and sold it for $100 did the store mark up the price by 30% what the answer
nevsk [136]

Answer:

Mark up  = 33.33%

Step-by-step explanation:

Given that:

buying price = $75

selling price = $100

First we will find the difference between two prices:

Difference = 100 - 75 = $25

We will find now that 25 is what percent of 75 so:

=25/75* 100

=  0.333333 * 100

= 33.33%

So the store marked the price by 33.33% instead of 30%

i hope it will help you!
