Answer:
13cm
Step-by-step explanation:
substitute values we have into the formula:
1664 = 16 x w x 8
rearrange:
1664/16×8 = w
which equals 13
For part B
the fixed cost is 500 dollars because it is a set inital amount, the varibale cost is .15 because it is the cost dependent on something else (per indicated variable part)
y=.15x+500
.15 cents per flyer, add 500 because that is the set amount it costs to even create the flyer
Plug in 500 for the equation
y=.15(500)+500
y=75+500
y=575
for part a
b=ka for direct variations so the direct one is C - two items directly multiplied
y=mx+b for partial variation so its A,D - basically the equation of a line
A is neither - shows neither of these relationships
Answer:
The sign is negative
Step-by-step explanation:
Given



Required
Determine the sign
The expression can be split into 3 factors

If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:

<em />
Leave only signs


So, we have:



So, we have:

<em>Hence, the sign of the expression is negative</em>
<em></em>
Take for instance;


The expression would be:
-- negative
We know for our problem that Rachel makes $10 per hour. Since

represent the number of hours that she works,

will be the total amount that she will make for working

hours. We also know that she sells bracelets for $5 each. Since

represents the number of of bracelets that she sells,

will be her total revenue for selling

bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of

and

must be equal or greater than 200:
