Cost of a pen = 95 cents = $0.95 ---------------------------->statement (1)
cos of a dozen of pen i.e. 12 pens = $9.95 ----------------> statement (2)
Now, Looking at statement (2)
when you buy a dozen of pen, it costs (12 / 9.95) = 1.206.....9 for each pen
Since, 1.206.....9 is greater than 0.95, the lowest price for which you can buy a pen is $0.95.
Now,
1 pen costs $0.95
40 pen costs ($0.95 * 40) = $38
So, the least possible cost in a dollars of 40 pens is $38.
Answer:
I=Prt, I=simple interest, P=principal (starting amount), r=interest as a decimal, t =number of times the interest is paid or "time"
For example the simple interest earned on a $1000 deposit earning 4% APR for ten years is:
I=1000(.04)10
I=$400.00
Step-by-step explanation:
The first thing we must do in this case is to calculate the surface area of the rectangular prism.
We have then:
A = 2 * ((L * h) + (L * w) + (h * w))
Where,
L: long
w: width
h: height
Substituting the values:
A = 2 * ((7.5 * 10) + (7.5 * 2) + (10 * 2))
A = 220
Then, "Manufacturing each box requires 10% more cardboard than the box's surface area"
Ar = 220 * 1.10
Ar = 242
242-220 = 22
Answer:
is needed 22 in ^ 2 cardboard to make each box
Answer: 14.97
That is the exact answer
We will use the Reminder theorem.
The polynomial f ( x ) is divisible by x - a when f ( a ) = 0.
For the 1st one:
f ( - 2 ) = ( - 2 )³ + 7 · ( - 2 )² + 14 · ( - 2 ) + 8 =
= - 8 + 28 - 28 + 8 = 0
For the 2nd one:
f ( 5 ) = 3 · 5³ - 12 · 5² - 4 · 5 - 55 =
= 375 - 300 - 20 - 55 = 375 - 375 = 0
Answer;
1. ( x + 2 )
2. ( x - 5 )
