A. 34.7 in.


B. 31 in.


C. 28.8 in.


D. 17.9 in.

Answers

Answer:

The answer is C. 28.8 in

Step-by-step explanation:

Given a=16 and b=24,

c = 28.84441 = 8√13

∠α = 33.69° = 33°41'24" = 0.588 rad

∠β = 56.31° = 56°18'36" = 0.98279 rad

h = 13.3128

area = 192

perimeter = 68.84441

inradius = 5.57779

circumradius = 14.42221 = 4√13

The equation would be y = -5/4x + 3.

To find slope you would use the slope formula of (y2-y1)/(x2-x1). This gives us the slope of -5/4. Then we find the y-intercept. When looking on the graph we see the only y intercept is the point (0,3), so we get the number 3.

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 diagonals

As 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 Diagonals

We 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.

Find the volume of a juice box that is 3 in by 1 1/2 in by 4 inches

Answers

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 inches

Interpreting the dimensions such as:

[tex]l = 3[/tex] inch[tex]w=1\frac{1}{2}=\frac{3}{2}[/tex] inch[tex]h = 4[/tex] inch

Using 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.

The sum of two numbers is 51.

The difference of the same two numbers is 9.

What are the two numbers?

Answers

Answer:

21 and 30

Step-by-step explanation:

x + y = 51

x - y = 9

add the two equations and y's will cancel out

2x = 42  divide by 2

x = 21   so put 21 in for x in the top equation and solve

21 + y = 51

y = 30

What is the least possible positive integer-value of n such that sqrt{18\cdot n \cdot 34}$ is an integer?

Answers

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
