Final answer:
Among the given options, the number 131 is a prime number, as it only has two divisors: 1 and itself.
Explanation:
The student has asked to identify which number among the given options is a prime number. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Analyzing the given options:
111 is divisible by 3.
121 is divisible by 11 (11 x 11).
131 is a prime number because it has no divisors other than 1 and itself.
141 is divisible by 3.
Therefore, the correct answer is 131, which is a prime number.

In two or more complete sentences, explain whether the sequence is finite or infinite. Describe the pattern in the sequence if it exists, and if possible find the sixth term. 2a, 2a2b, 2a3b2, 2a4b3. . .
Answer:
a). it is an Infinite Sequence.
b). This sequence is Geometric Progression.
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]
Step-by-step explanation:
Given: A Sequence 2a , 2a²b , 2a³b² , [tex]2a^4b^3[/tex]
To find: a). Given Sequence is finite or infinite
b). Pattern of the sequence
c). Sixth term
a). Since, there is no detail about no. of terms of the sequence.
Therefore, It implies it is an Infinite Sequence.
b). Given 1st term = 2a , 2nd term = 2a²b , 3rd term = 2a³b²
First we find the difference of 1st and 2nd term
d = 2a²b - 2a ⇒ d = 2a (ab - 1)
Now, Difference of 2nd and 3rd term,
d = 2a³b² - 2a²b = 2a²b (ab - 1)
So, This Sequence is not a Arthematic Progression.
Now, we find the ratio of 2nd term to 1st term,
[tex]r\:=\:\frac{2a^2b}{2a}\,=\,ab[/tex]
Ratio of 3rd term to 2nd term,
[tex]r\:=\:\frac{2a^3b^2}{2a^2b}\,=\,ab[/tex]
Since, the ratio is common.
This sequence is Geometric Progression.
So, Pattern is next term of this sequence has 1 more in power of a and b
⇒ [tex]nth\,term\,of\,this\,GP\,=\,2a^{n}b^{n-1}[/tex]
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^{6}b^{6-1}[/tex]
[tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]
Therfore, a). it is an Infinite Sequence.
b). This sequence is Geometric Progression.
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]

Veronique and Lily compare their investment accounts to see how much they will have in the accounts after seven years. They substitute their values shown below into the compound interest formula. Compound Interest Accounts Name Principal Interest Rate Number of Years Compounded Veronique $1,000 5% 7 Once a year Lily $1,800 9% 7 Once a year mc017-1.jpg Which pair of equations would correctly calculate their compound interests? Veronique: mc017-2.jpg, Lily: mc017-3.jpg Veronique: mc017-4.jpg, Lily: mc017-5.jpg Veronique: mc017-6.jpg, Lily: mc017-7.jpg
Answer:
A
Step-by-step explanation:
The pair of equations that would correctly calculate their compound interests are:
Veronique's interest = A = 1000(1 + 0.05/1)⁷ - 1000 = 407.10
Lily's interest = 1800(1 + 0.09/1)⁷ - 1800 = 1,490.47.
What is the compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n)^(nt)
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
For Veronique, we have:
A = 1000(1 + 0.05/1)⁷ = $1,407.10
For Lily, we have:
A = 1800(1 + 0.09/1)⁷ = $3290.47
To calculate the compound interest for each account, we subtract the principal amount from the final amount:
For Veronique:
Interest = A - P = $1,407.10 - $1,000 = $407.10
For Lily:
Interest = A - P = $3,290.47 - $1,800 = $1,490.47
Therefore, the pair of equations that would correctly calculate their compound interests are:
Veronique's interest = A = 1000(1 + 0.05/1)⁷ - 1000 = 407.10
Lily's interest = 1800(1 + 0.09/1)⁷ - 1800 = 1,490.47.

A machine cuts a strip of carpet into two pieces. The length of the smaller piece is 5 meters greater than the length of the larger piece. If the length of the smaller piece is 12 meters, the length of the bigger piece is meters and the total length of the carpet is meters.
Answer:
The length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.
Step-by-step explanation:
The length of the smaller piece is 5 meters greater than the length of the larger piece.
i.e. Length of larger piece=Length of smaller piece+5
The length of the smaller piece is 12 meters.
So, Length of larger piece=12+5
=17 meters
Total Length of carpet=Length of smaller piece + Length of larger piece
= 12+17
= 29 meters
Hence, the length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.

A small train at an amusement park is carrying passengers. Half of the passengers are 6 years old, 1 over 10 are 7 years old, 1 fifth are 8 years old, and 1 fifth are 9 years old.
What is the expected age for one of the passengers on the train?
6 years
7.1 years
8 years
8.5 years
The expected age for one of the passengers on the train is 7.1 years. This can be explained by following steps:
Following are the calculation for the expected age given
½ = 6 years old
1/10 = 7 years old
1/5 = 8 years old
1/5 = 9 years old
With the help of the above information, expected age can be calculated as follows:
Expected age = ½*6+1/10*7+1/5*8+1/5*9
= 6/2+7/10+8/5+9/5
=3+0.7+1.6+1.8
= 7.1
Therefore, the correct answer is 7.1 years old.

The perimeter of a rectangle is 36 yards. The width is 18 yards less than twice the length. Find the length and the width of the rectangle
The length of the rectangle is 12 yards and the width is 6 yards. The problem is solved with algebra using the formulas for the perimeter of a rectangle and given relation between the length and width.
Explanation:This problem involves the use of algebra in solving geometrical problems. The question provides information about the perimeter and the relationship of length to width using algebraic expressions. To find the length and the width, we can use the formulas for the perimeter of a rectangle (P=2L + 2W) and the given width (W=2L-18).
Let L represent the length. Then, 2L+W=18 represents the width. Setting 2L + 2W equal to the given perimeter of 36, we get 2L + 2(2L - 18) = 36.
Solving this equation gives: L = 12, and substituting L=12 into W=2L - 18, we get: W=6. Hence, the length is 12 yards and the width is 6 yards.
