A glacier moves about 12 inches every 36 hours. About how far does the glacier move in 1 week?

Answers

Answer 1
Answer: \begin{array}{cccccc}12in&-&36h&/:3\n\n4in&-&12h&/\cdot2\n\n8in&-&24h=1day&/\cdot7\n\n42in&-&7day=1week\end{array}\n\n\n\nAnswer:42\ inches.
Answer 2
Answer: So first you would divide 12 in half to figure out how many inches it moves in 24 hours (or 1 day) which would be 6 inches every 24 hours. You then multiply 6 (inches per day) by 7 (# of days). You end up with 42 inches in 7 days. Hope this helps

Martha estimated there were 95 marbles in a jar for a contest. The actual number of marbles in the jar was 117. What was the percent error of Martha's estimation?

22%
81.20%
23.16%
18.80%

Answers

It is 18.80%. You use the percent error formula: %error= (true value-estimated value)/true value. So (117-95)/117 = .188034188. You multiply by 100 since you are finding the percent not the decimal and you get about 18.80%

What is the GCF of 56 and 40

Answers

Okay so the factors for 56 are 1, 2, 4, 7, 8, 14, 28, and of course 56. So the factors for 40 are 1, 2, 4, 5, 8, 10, 20, and of course 40. 
Okay so now the prevalent factors are now 1, 2, 4, and 8.
So the greatest prevalent factor is now 8.
The GCF can be calculated by identifying the prevalent prime numbers and by withal multiplying them together.
The prime factors of 56 are 2, 2, 2, and 7
The prime factors of 40 are 2, 2, 2, and 5. 
Okay so now the prime factors in prevalence are 2, 2, and 2, so the greatest mundane factor is 2 x 2 x 2 = 8.
I do hope this helps you!
8 it will be there 8 goes evenly into both 56 and 40 hope this helped

The first thing is to define each one:

Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.

Example:

This is a:  5x^(3) + 4x^(2) -99x +20

Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.

Example: 5x^(3) + 4x^(2) -99x +20

The degree of this polynomial is 3 because it is the largest exponent.

Linear term coefficient: is the number that multiplies the variable with the highest exponent

Example: 5x^(3) + 4x^(2) -99x +20

In this case it is 5 because x^(3) is the variable with the highest exponent

Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.

Example:  5x^(3) + 4x^(2) -99x +20

In this case it is 20 because it is the one found without multiplying any linear term (x)
