1. One rule of thumb for estimating crowds is that each person occupies 2.5 square feet. Use this value to
givi [52]

Answer:

216 people

Step-by-step explanation:

Given:

2.5 feet² is occupied by 1 person

Dimension of room = 216 in × 360 in

Required:

No. of people that would occupy the room

SOLUTION:

Step 1:

Convert the dimensions of the room from in to ft

Note: 1 foot = 12 inches

216 inches = \frac{216}{12} = 18 ft

360 inches = \frac{360}{12} = 30 ft

Step 2: calculate area of the room.

Area of the room = 30*18 = 540 ft²

Step 3: calculate the no. of people the room will contain.

2.5 ft² will contain one person

Therefore, 540 ft² will contain: \frac{540}{2.5} = 216 people

The lakeside marina charges a $35 rental fee for a boat in addition to charging $15 per hour. Part D:what information does the i
STALIN [3.7K]

Answer: B.The cost of rental fee only

Step-by-step explanation:

The $35 is the cost of the rental fee only. The person would then have to pay a further $15 for every hour they use the boat.

Essentially, the $35 is the fixed cost associated with the rental and the $15 is the variable cost to do so. If this were in a linear equation format it would take the form: y = 15x + 35.

The product of two irrational numbers is. Rational
Snowcat [4.5K]

Answer:

So the statement:

"The product of two irrational numbers is rational." is false.

Step-by-step explanation:

The product of two irrationals can be irrational or rational.

Example:

\sqrt{2} \cdot \sqrt{2}=2

\sqrt{2} is irrational but when you multiply it to itself the output is rational.

Example:

\sqrt{2} \cdot \sqrt{3}=\sqrt{6}

\sqrt{2} \text{ and } \sqrt{3} are irrational and when you multiply them you get an irrational answer of \sqrt{6}.

So the statement:

"The product of two irrational numbers is rational." is false.

X and y are positive integers. explain why incorrect to claim that
dedylja [7]

You can find counterexamples to disprove this claim. We have positive integers that are perfect square numbers; when we take the square root of those numbers, we get an integer.

For example, the square root of 1 is 1, which is an integer. So if y = 1, then the denominator becomes an integer and thus we get a quotient of two integers (since x is also defined to be an integer), the definition of a rational number.

Example: x = 2, y = 1 ends up with \frac{2}{\sqrt{1}} = \frac{2}{1} which is rational. This goes against the claim that x/\sqrt{y} is always irrational for positive integers x and y.

Any integer y that is a perfect square will work to disprove this claim, e.g. y = 1, y = 4, y= 9, y = 16. So it is not always irrational.

s2008m [1.1K]

Hey!

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

Solution:

Remember to follow PEMDAS!

= 3 + 2 ⋅ [(2 + 1) ⋅ 5 + 8]

= 3 + 2 ⋅ [(15) + 8]

= 3 + 2 ⋅ [23]

= 3 + 46

= 49
