Answer:
The answer is 25g^R4
Step-by-step explanation:
When you solve the equation, it becomes 25g^R4, it doesn't result in a whole number.
Answer:
First write them in positive exponent form
(16/81)¾ × [ (9/25)^3/2 ÷ (2/5)³ ]
(2⁴×¾)/ (3⁴×¾) × [ (3² × ^3/2) / (5² ×^3/2) ÷ 2³/5³)
Simplify the terms
2³/3³ × ( 3³ / 5³ ÷ 2³/5³)
Solve the terms in the bracket
2³/3³ × (3³/5³×5³/2³)
You will get
2³/3³ × 3³/2³ = 1
They will cancel each other so the answer will be 1
Hope this helps.
Answer: 5
Step-by-step explanation: 5 x 5 is 25 + 8 is 33
<h2>
For a. </h2>
While in the blueprint, each square is 1/4...in real life, it's 4 feet per square.
Meaning, the area of each square is (4 x 4) 16 square feet.
Since there are 8 squares/tiles in the bathroom...
...multiply 8 x 16 = 128 square feet in real life.
Multiply that with the cost, and since it costs $5 per square feet:
<h2>128 x 5 =
$640 (answer)</h2>
<h2>
For b. </h2>
Do it in similar steps.
Living room: 4 x 7 = 28 tiles
Bedroom: 4 x 5 = 20 tiles
20 + 28 = 48 tiles (in blueprint)
...multiply 48 x 16 = 768 feet square (in real life)
<em />
<em>[Convert feet into yards...3 feet equals 1 yard]</em>
a square yard would be 3 feet x 3 feet = 9 feet...
...divide 768 by 9
768 ÷ 9 = 85.33 square yards (rounded up)
Multiply that with the cost, and since it costs $18 per square feet:
<h2>85.53 x 18 =
$1535.94 (answer)</h2>
