Answer:

--------------

y-1

with the restriction y cannot equal -1

Step-by-step explanation:

y+1

--------------

y^1 -1

Noticing that the denominator is the difference of squares and factoring

y+1

--------------

(y+1)(y-1)

Canceling like terms

--------------

y-1

with the restriction y cannot equal -1

30 points.. Please Help! I don't understand what to do with this question...a bit confused.

Eh, here's my best try for a table:

Like tv don't like tv total
Like reading: 70 10 80
Don't like read. 20 30 50 
total 90 40 130

The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.

The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]

Hope this somehow helped you :)

Which expressions are equivalent to 1 5 ⋅ 1 5 ⋅ 1 5 ⋅ 1 5 5 1 ⋅ 5 1 ⋅ 5 1 ⋅ 5 1 start fraction, 1, divided by, 5, end fr

Sergio039 [100]

Answer:

The possible expressions are:

$\frac{1}{5} X \frac{1}{5} X \frac{1}{5}X \frac{1}{5}$

$\frac{1}{5^4}$

$\frac{1}{625}$

Step-by-step explanation:

We are to determine the expression equivalent to:

$\frac{1}{5} \cdot \frac{1}{5} \cdot \frac{1}{5}\cdot \frac{1}{5}$

Since the options are not listed, I would give you possible answers.

$\frac{1}{5} \cdot \frac{1}{5} \cdot \frac{1}{5}\cdot \frac{1}{5} = \frac{1}{5} X \frac{1}{5} X \frac{1}{5}X \frac{1}{5}$

$\frac{1}{5} X \frac{1}{5} X \frac{1}{5}X \frac{1}{5}=(\frac{1}{5})^4=\frac{1^4}{5^4}=\frac{1}{5^4}$

$\frac{1}{5} X \frac{1}{5} X \frac{1}{5}X \frac{1}{5}=\frac{1}{625}$

A large city in the ancient world was square-shaped. measured in miles, its area numerically exceeded its perimeter by about 132

melisa1 [442]

Area = perimeter + 132.

Let each side of the city be x miles long, then:-

x^2 = 4x + 132
x^2 - 4x - 132 = 0

x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2

x = 13.66, -9.66 We ignore the negative

So the city has dimension of 13.66 * 13.66

13.7 * 13.7 to nearest 10th
