27. A factory worker has 5,500 puzzles to pack into cartons that each hold 785 puzzles. How many puzzles will be left over after the last box is full? A. 5 B.6 C.7 D.8
Answer:
C. 7
Step-by-step explanation:
5,500 divided by 785 = 7.006, which can be rounded to 7.
The number of puzzle will be left over after the last box is full is 5. Therefore, the correct answer is option A.
Given that, a factory worker has 5,500 puzzles to pack into cartons that each hold 785 puzzles.
The number of cartons required = 5500/785
The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Now,

Need Help!!!!!!!!!!!!!!Find the outer perimeter of this figure. Round your answer to the nearest hundredth.
Answer:
The perimeter of the figure is 14.71 ft
Step-by-step explanation:
The outer perimeter of the figure is the sum of the boundary dimensions.
The missing outer dimension is the length of the arc or half circumference.
Length of arc formula/half circumference = 1/2 πr = 1/2 x 3.14 x 3 ft = 4.71 ft
The other dimensions are 5ft and 5ft.
Therefore, the outer perimeter of the figure is:
4.71 ft + 5 ft + 5 ft = 14.71 ft

A polynomial is
if its only factors over the integers are 1 and itself.
Answer: Prime
A polynomial is prime if its only factors over the integers are 1 and itself.
==============================================================
Explanation:
Think of the idea of factoring whole numbers like factoring 36 into 6*6 which further breaks down into (2*3)*(2*3) = 2^2*3^2. This shows that 36 is composite and not prime.
Something like 7 is prime because the only factors are 1 and itself.
This idea extends into polynomials as well.
Something like x^2+4x+4 factors to (x+2)(x+2) which shows it is not prime. On the other hand, the polynomial x^2+3x+5 is prime over the integers because we cannot factor it like the previous example. The only factors here are 1 and itself.
Factoring is handy to help determine roots of a polynomial. However, other tricks could be used such as the quadratic formula or using numerical approximation techniques.

An art museum recently discovered that 12% of their paintings had been stolen and replaced with replicas. If a tourist observes 3 different paintings at random, what is the probability that exactly 2 are fakes? Write your answer as a decimal rounded to the nearest thousandth.
We will find that the probability that exactly one is original (or that exactly two are fakes) is 0.038
We know that 12% of the paintings are replicas.
Then if we see a random painting, the probability that it is a replica is 0.12
This means that the probability that a random painting is not a replica, is 1 - 0.12 = 0.88
Now we want to find the probability that exactly two out of 3 paintings are fake.
An easier thing to find is the probability that exactly one of the paintings is original (is exactly the same thing, just another viewpoint).
Let's assume the paintings are ordered, and the first one is the original one.
The probability of this will be:
P = 0.88*0.12*0.12
But we also have the case where the second one is the original, and the case where the third one is the original, so we have 3 possible permutations.
This means that the probability that exactly one is original (or that exactly two are fakes) is:
P = 3*(0.88*0.12*0.12) = 0.038
