Answer:

162.5 or 162 and a half gallons

Step-by-step explanation:

According to the question, Samantha has a rectangular shaped fish tank in her room the tank has a height of 2.6 feet, a width of 2.1 feet and a length of 3.98 feet.

We are now told to find out the amount of water the fish tank can hold.

When it comes to filling a rectangular tank, we need to know the dimensions of the tank(it's length,width and height)

Here the volume of the tank will be

Lenght× Width × Height

= 2.6 ×2.1 ×3.98

=21.7308

Convert the volume in cubic feet to the capacity in

gallons. Multiply the tank’s volume by 7.48, the

number of gallons in a cubic foot. For example,

104.625x7.48 = 782.6 gallons.

So here the conversion to number of gallons will be

21.7308 × 7.48 = 162.5 or 162 and a half gallons will fill the fish tank

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

3x + 5(2 + x) = 4x - 7

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute 5:                                                                 3x + 10 + 5x = 4x - 7
  2. [Addition] Combine like terms:                                                                        8x + 10 = 4x - 7
  3. [Subtraction Property of Equality] Subtract 4x on both sides:                      4x + 10 = -7
  4. [Subtraction Property of Equality] Subtract 10 on both sides:                       4x = -17
  5. [Division Property of Equality] Divide 4 on both sides:                                  x = -17/4

Law Incorporation [45]

Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625


Step-by-step explanation:

Given: Vanessa and Zack are playing a game where the player with the lower score wins.

Score of Vanessa=-3\frac{5}{8}=-(\frac{29}{8})=-3.625

Score of Zack = -3\frac{2}{3}=-(\frac{11}{3})=-3.666

We can see -3.666

⇒ Zack has the lower score .

Hence, Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
