The simplified ratio of the width of a seating section to the width of the stairs, using proportions, is of:

120.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and these proportions are built in the context of a problem, involving basic arithmetic operations, especially multiplication and division, to find the desired measures.

One example of application of proportions is for ratio problems, as the ratio between two amounts a and b is given by the division of the amount a by the amount b.

A seating section is composed as follows:

  • 30 seats.
  • Each set has a width of 24 feet.

Hence the total width of a seating section is calculated as follows:

30 x 24 = 720 feet.

The width of a stair is:

6 feet.

Hence the ratio of these widths is given as follows:

720/6 = 120.

HURRY PLEASE!!! I NEED TO TURN THIS IN SOON<br><br> i need an explanation too.
Dominik [7]

Answer:

X = 30°, y = 15° and z = 150°.

Reason: Look below.

Step-by-step explanation:

Hey there!

When we look into the figure, we find that;

For x:

x+ 2x + 90° = 180° {Being linear pair}

or, 3x = 180°-90°

or, 3x = 90°

or, x= 90°/3

<u>Therefore, X = 30°.</u>

For y :

2y = x = 30° {Alternate angles are equal}

or, 2y = 30°

y = 30°/2

<u>Therefore, y = </u><u>1</u><u>5</u><u>°</u>

For z:

2y + z = 180° { Being linear pair}

or, 30°+z = 180°

or, z = 180°-30°

or, z = 150°

<u>Therefore, z = 150°.</u>

Use the given graph of f to state the value of each quantity, if it exists. (If an answer does not exist, enter DNE.)
alex41 [277]

Answer:

Hence the answer is given as follows,

Step-by-step explanation:

Graph of y = f(x) given,

(a) \lim_{x\rightarrow 2^{-}}f(x)=3

(b) \lim_{x\rightarrow 2^{+}}f(x)=1

(c) \lim_{x\rightarrow 2}f(x)= DNE \left \{ \therefore \lim_{x\rightarrow 2^{-}} f(x)\neq  \lim_{x\rightarrow 2^{+}}f(x) \right.

(d) f(2)=3

(e) \lim_{x\rightarrow 4}f(x) = 4

(f) f(4)= DNE.{ Hole in graph}

Hence solved.
