What is the least possible positive integer-value of n such that sqrt{18\cdot n \cdot 34}$ is an integer?
Answer:
n = 17. This means, √(18 x 17 x 34) = √(10404) = 102.
Step-by-step explanation:
An integer is a number that is not a fraction.
Given √(18 x n x 34), for the expression to be an integer, the product must be a perfect square. We are looking for n, the smallest number to multiply 18 x 34 to make it a perfect square. We have:
18 x 34 = 2 x 9 x 2 x 17 = 2 x 3 x 3 x 2 x 17 = 2² x 3² x 17.
From here, we see that we need to multiply an extra 17 to make it a perfect square, therefore n = 17. So we have:
√(18 x 17 x 34) = √(10404) = 102
The least possible positive integer-value of n such that [tex]\sqrt{18\cdot n \cdot 34}[/tex] is an integer is 17
The expression is given as:
[tex]\sqrt{18\cdot n \cdot 34}[/tex]
Expand the equation
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 9 \times n \times 2 \times 17}[/tex]
Express 8 as 3^2
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 3^2 \times n \times 2 \times 17}[/tex]
Rearrange the factors as follows:
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 2\times 3^2 \times n \times 17}[/tex]
Express 2 * 2 as 2^2
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2^2\times 3^2 \times n \times 17}[/tex]
Evaluate all exponents
[tex]\sqrt{18\cdot n \cdot 34} = 2\times 3 \times \sqrt{n \times 17}[/tex]
[tex]\sqrt{18\cdot n \cdot 34} = 6 \times \sqrt{n \times 17}[/tex]
For the expression to be an integer, then the radical must be a perfect square.
Given that the expression in the radical is [tex]{n \times 17[/tex], then the value of n must equal 17, at the very least
i.e.
[tex]n = 17[/tex]
Hence, the least possible positive integer-value of n is 17

b. Lin wants to use a number cube to simulate the result of one dart. She suggests that 1 on the number cube could represent a win. Getting 2, 3, 4 could represent no point scored. She says that she would ignore getting a 5 or 6. Is Lin's suggestion for a simulation appropriate? Explain why you would use it, or if not, how you would change it.
Answer:
Step-by-step explanation:
I would not use her suggestion because you don't know what 5 you get if you win 5 or 6. I would change it only by seeing what you would get if you score 5 or 6.
Find the volume of a juice box that is 3 in by 1 1/2 in by 4 inches
Answer:
The volume of a juice box is 18 cubic inches.
Step-by-step explanation:
Given the dimensions
3 in by 1 1/2 in by 4 inchesInterpreting the dimensions such as:
[tex]l = 3[/tex] inch[tex]w=1\frac{1}{2}=\frac{3}{2}[/tex] inch[tex]h = 4[/tex] inchUsing the formula to determine the volume
[tex]V=\:l\:\times \:w\:\times \:h[/tex]
substitute l = 3, w = 3/2, h = 4
[tex]V=3\times \frac{3}{2}\times \:4[/tex]
[tex]V\:=\:\frac{36}{2}[/tex]
[tex]V = 18[/tex] cubic inches
Therefore, the volume of a juice box is 18 cubic inches.

If JN=x+3 and JL 3x + 1, determine which of the following values is correct
Answer:NM=8
Step-by-step explanation:
JN is half of JL so x + 3 times 2 is equal to 3x + 1
then u just do the work
2x+6=3x+1
5=x
then you just plug in the answers and JN is equal to 8 therefore NM is also equal to 8
To solve the problem we must know about the properties of the diagonals of a rectangle.
What are the properties of the diagonals of a rectangle?The diagonals of a rectangle are of equal length.The diagonals of the rectangle bisect each other at equal distances.The correct statement from all the given options is D.
Given to us
JN = x+3
JL = 3x+1
What is the value of x?We know that the diagonals of the rectangle bisect each other at two equal parts, therefore, JN=NL, also
[tex]JL = JN + NL\\\\\text{Substituting the values,}\\\\3x+1 = x+3 + NL\\\\3x+1 = x+3 + NL\\\\3x-x=3-1+NL \ \ \ \ \ [JN=NL]\\\\2x = 2 + JN\\\\2x = 2 + x+3\\\\2x-x=5\\\\x = 5[/tex]
Value of diagonalsAs we know the values of the diagonals are equal, therefore,
JL = KM = 3x + 1
JL = KM = 3(5) + 1
JL = KM = 16
Value of half DiagonalsWe know that the diagonals of the rectangle bisect each other at two equal parts, also the diagonal are equal therefore all the four parts of the two diagonals will be equal.
JN = NL = KN = NM = x+3
JN = NL = KN = NM = 5+3
JN = NL = KN = NM = 8
Hence, the correct statement from all the given options is D.
