The correct option is:   D. 2\frac{7}{8}

<u><em>Explanation</em></u>

As the price of each meat package is same that is $12.99, so the <u>best deal will be when the weight of the package will be greatest</u>.

The weight are  2\frac{9}{11}, 2\frac{4}{5}, 2\frac{2}{3} and 2\frac{7}{8} pounds. For finding the fraction which has greatest value, first we will <u>convert them into improper fraction and then make their denominators same. LCM of the denominators is 1320</u>. So......

2\frac{9}{11}= \frac{31}{11}= \frac{31*120}{11*120}=\frac{3720}{1320} \\ \\ 2\frac{4}{5}= \frac{14}{5}=\frac{14*264}{5*264}=\frac{3696}{1320}\\ \\ 2\frac{2}{3}=\frac{8}{3}=\frac{8*440}{3*440}=\frac{3520}{1320}\\ \\ 2\frac{7}{8}=\frac{23}{8}=\frac{23*165}{8*165}=\frac{3795}{1320}

We can see that 3795 is the greatest numerator. So, 2\frac{7}{8} has the greatest value.

Thus, the best deal will be 2\frac{7}{8} pounds.

Is is square root of 1.6875 a rational number
mamaluj [8]

<em><u>Question:</u></em>

Is square root of 1.6875 a rational number ?

<em><u>Answer:</u></em>

Square root of 1.6875 a rational number is not a rational number

<em><u>Solution:</u></em>

Given that we have to find square root of 1.6875 and determine if it is rational number or not

Let us first find square root of 1.6875

\sqrt{1.6875} = 1.29903810568

Let us understand about rational number

A rational number is a number that can be expressed as a fraction (ratio) in the form \frac{p}{q} where p and q are integers and q is not zero.

When a rational number fraction is divided to form a decimal value,  it becomes a terminating or repeating decimal.

So the number 1.29903810568 is not a rational number

<em><u>In other words we can say,</u></em>

Only the square roots of square numbers are rational. Here 1.6875 is not a perfect square. So it is not rational number

An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 340 feet of antique
KIM [24]

Answer:

The dimensions of the garden is 102 feet by 68 feet

Step-by-step explanation:

Here, we want to get the width and length of the garden

The perimeter is represented by the length of the fencing

From the question;

w = 2l/3

The formula for the perimeter is;

P = 2(l + w)

Thus;

340 = 2(l + 2l/3)

170 = (l + 2l/3)

Multiply through by 3

510 = 3l + 2l

5l = 510

l = 102 feet

w = 2/3 * l

w = 2/3 * 102

w = 68 feet
