Answer:
The profit = $(3x - 75) where x = number of t-shirts sold
Step-by-step explanation:
School spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print.
We have to find the club's income if they sell each t-shirt for $8.
Let the number of t-shirts that the club sell be equal to x.
So the cost of making x t-shirts = 75 + 5x
If the club sells x t-shirts , then the money they earn = 8x
Profit = selling price - cost price
= 8x - (75 + 5x)
= $(3x - 75)
The club also needs to sell at least 25 t-shirts to make a profit and from then on makes a profit of $3 on each t-shirt they sell.
By the pythagorean theorem the diagonal length will be:
d^2=x^2+y^2 and since this is a square x=y so
d^2=2x^2 and since d=15
225=2x^2
x^2=112.5
x=√112.5 yds
x≈10.6 yds (to nearest tenth of a yard)
1 foot = 12 inches (you're supposed to know this)
so
2 feet = 24 inches
and
3 feet = 36 inches .
Answer:
They have the same slope of 2 and are, therefore, parallel.
Step-by-step explanation:
Given: Equation of FG is 
and equation of EH is 
To find: Relation between segments FG and EH
Solution:
Slope of a line describes its direction and the steepness.
Two lines are said to be parallel if their slopes are equal.
Differentiate with respect to x
where 
denotes the slope of the line FG
Differentiate with respect to x
where 
denotes slope of line EH
As 
, lines are parallel
