Answer:

Step-by-step explanation:

Perimeter of rectangle = 5y - 1 + 4y + 2 + 5y - 1 + 4y + 2

= 18y + 2

18y + 2 = 128

18y = 128 - 2

= 126

y = 126 ÷ 18

y = 7

Length of AD = 4y + 2

= 4(7) + 2

= 28 + 2

= 30

Rewrite using factors and exponents, then simplify<br> 1. 1000/100 2. 9/81 3. 4/64

marta [7]

1) 1000 / 100 ⇒ 10 / 1 = 10
1000 ÷ 100 = 10
100 ÷ 100 =   1

2) 9/81 ⇒ 1/9
  9 ÷ 9 = 1
81 ÷ 9 = 9

3) 4/64 ⇒ 1/16
  4 ÷ 4 =   1
64 ÷ 4 = 16

The results of an election are shown in the table below.

vazorg [7]

We are given the results of an election:

Candidate Fraction of votes

Johnson = $\frac{1}{9}$

Smith = $\frac{7}{18}$

Dragovic = $\frac{1}{2}$

Now, we need to find the difference between the fractions of votes received by Dragovic and Johnson.

Therefore, difference is :

$\frac{1}{2} - \frac{1}{9}$

Taking common denominator of 2 and 9 is 18.

$=\frac{1\times9}{2\times 9} - \frac{1\times 2}{9\times 2}$

$=\frac{9}{18} - \frac{2}{18}$

$=\frac{9-2}{18}$

$=\frac{7}{18}$

Therefore, the difference between the fractions of votes received by Dragovic and Johnson is $\frac{7}{18}$ .
