No because Pi is an irrational number so adding 2 to Pi will also be irrational.

For which value of a are all the solutions of 2(x-5)&gt;3x+a less than or equal 5?
saveliy_v [14]
2(x-5)>3x+a \\&#10;2x-10 > 3x+a \\&#10;2x-3x>a+10 \\&#10;-x>a+10 \ \ \ |\times (-1) \\&#10;x

The solutions must be less than or equal to 5.
-a-10 \leq 5 \\&#10;-a \leq 5+10 \\&#10;-a \leq 15 \ \ \ |\times (-1) \\&#10;a \geq -15

All the solutions are less than or equal to 5 for a≥-15.

Charlie's garage has a rectangular floor space. Its length is 3 times its width. Charlie extends the width of his garage to 6 m,
MAXImum [283]

Answer:

The percentage change is 140%

Step-by-step explanation:

Given

L= 3W_1 ---- initial dimension

W_2 = 6m --- new width

A_2 = 45m^2 --- new dimension

Required

The percentage increment

The length remains constant because only the width is extended.

The new area is:

Area =Length * Width

A_2=L * W_2

Make L the subject

L = \frac{A_2}{ W_2}

Substitute values for A and W

L = \frac{45m^2}{6m}

L = \frac{45m}{6}

L = 7.5m --- this is the length of the garden

Calculate the initial width:

L= 3W_1

Make W1 the subject

W_1 = \frac{1}{3} * L

W_1 = \frac{1}{3} * 7.5

W_1 = 2.5

So, the initial area is:

A_1 = L_1 * W_1

A_1 = 2.5 * 7.5

A_1 = 18.75

The percentage change in area is:

\%A = \frac{A_2 - A_1}{A_1}

\%A = \frac{45 - 18.75}{18.75}

\%A = \frac{26.25}{18.75}

\%A = 1.4

Express as percentage

\%A = 1.4*100\%

\%A = 140\%
