Answer:
Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.
Step-by-step explanation:
Given that,
The function that models the production cost is
To find the number of t-shirt, we put f(t)=40 in given function.
∴40= 0.1t²-6t+100
⇒ 0.1t²-6t+100-40=0
⇒0.1 t²- 6t +60=0
⇒t²-60t+600=0
Applying quadratic formula 
, a=1, b= - 60 and c=600
= 47.32,12.67
≈47, 12
Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.
6 5/6 - 5 1/12
6 5/6 x 2
6 10/12 - 5 1/12
6-5=1
10-1= 9
( You don't subtract the 12s in subtraction)
1 9/12
Simplified
1 9/12 both divided by 3
1 3/4
Final answer 1 9/12
Simplified answer 1 3/4
Answer:
The difference between x and seven.
Step-by-step explanation:
Step 1: Convert <em>x</em> to word form
<em>x</em> = a number
Step 2: Convert - to word form
- = difference
Step 3: Convert 7 to word form
7 = seven
Step 4: Combine
The difference between x and seven.
Answer:
C
Step-by-step explanation:
So if x is the number, then 4 times the number would be 4x and adding that to -8 would be 4x + (-8) and then 12 times the number would be 12x, so you have 4x + (-8) = 12.
Then, solve:
subtract 4x from both sides
divide both sides by 8
I think it is low hope I am right
