Answer:

the smallest number is the lower bound and the largest number is the upper bound, your inequality would be

8.2 ≤ x ≤ 9.5, where x represents the volume of tennis balls.

A house with ceilings that are 2.4 meters high has five rectangular rooms with the following dimensions: 4 meters 3 5 meters; 4

Answer:

A 21,000-Btu unit that will cool 340 cubic meters;

Step-by-step explanation:

Calculating the volume of the five rooms, we have;

Room 1:

Volume = 2.4 *4*5

= 48 m³

Room 2:

Volume = 2.4*4*4

= 38.4 m³

Room 3:

Volume = 2.4*6*4

=57.6 m³

Room 4:

Volume = 2.4*6*6

=86.4 m³

Room 5:

Volume = 2.4*6*5.5

= 79.2 m³

Total volume of the room = 48 +38.4 + 57.6 + 86.4 + 79.2

= 309.6 m³

From the total volume obtained above, the air condition that will be adequate to cool the house is 21,000-Btu unit since the obtained volume(309.6 m³) is within the range of the specify volume (340 cubic meters).

How do you write y+1=4/5(x-3) in standard form?

Rudik [331]

Answer:

The standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$

Step-by-step explanation:

Here, the given expression is $y + 1 = \frac{4}{5} (x-3)$

Now, the Standard Form of the equation is ax + by + c = 0

Solving this, we get:

$y + 1 = \frac{4}{5} (x-3) \implies y + 1 = (\frac{4}{5})x - \frac{12}{5}$

⇒ $y + 1 - (\frac{4}{5})x + (\frac{12}{5}) = 0$

or, $y - (\frac{4}{5})x + (\frac{12}{5} + 1 )= 0 \implies y - (\frac{4}{5})x + (\frac{12+ 5}{5}) = 0$

⇒ $y - (\frac{4}{5})x + (\frac{17}{5}) = 0$

Hence, the standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$
