Answer:

$\frac{4}{9}$

Step-by-step explanation:

$\frac{2}{3} * \frac{2}{3}$

you multiply across, so you do 2*2 for the numerator, then 3*3 for the denominator. This would equal 4 as the numerator, 9 as the denominator, which is $\frac{4}{9}$

To compute the slope of a segment, given its endpoints $A(A_x,A_y),\ B=(B_x,B_y)$ , you write

$m_{AB} = \dfrac{A_y-B_y}{A_x-B_x}$

Given this formula, you have the four slopes:

$m_{AB} = \dfrac{A_y-B_y}{A_x-B_x} = \dfrac{-1-2}{-4+1} = \dfrac{-3}{-3} = 1$

$m_{BC} = \dfrac{B_y-C_y}{B_x-C_x} = \dfrac{2-1}{-1-5} = \dfrac{1}{-6} = \dfrac{-1}{6}$

$m_{CD} = \dfrac{C_y-D_y}{C_x-D_x} = \dfrac{1+3}{5-1} = \dfrac{4}{4} = 1$

$m_{DA} = \dfrac{D_y-A_y}{D_x-A_x} = \dfrac{-3+1}{1+4} = \dfrac{-2}{5} = -\dfrac{2}{5}$

Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.

This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.

If 588 digits were used to number the pages of a book how many pages are in this book.

iVinArrow [24]

Answer: 232 pages

Step-by-step explanation:

Total digits = 588

1 digit page number:

1 to 9 = 1 × 9 = 9

Number of pages = 9/1 = 9

2 - digit page number :

10 - 99 = 2 × 90 = 180

Number of pages = 180/2 = 90

3 - digit page number :

588 - (9 + 180) = 588 - 189 = 399

Number of pages with 3 - digits = 399/3 = 133

Therefore, the total number of pages the book has is :

(9 + 90 + 133) = 232 pages

Compute the amount of interest earned in the following simple interest problem.

Mumz [18]

Answer:

Step-by-step explanation:

P = $295

r =7%

t = 270 days = 270/365

Interest = Prt

$=295*\frac{7}{100}*\frac{270}{365}\\\\= 15.28$

= $ 15.28

Amount = 295 + 15.28

Amount = $310.28
