Answer:
Step-by-step explanation:
We can find the area by breaking this into two rectangles one 3 by 7 and the other 1 by 2. The area of any rectangle is xy where x and y are its dimensions
A=3(7)+1(2)
A=21+2
A=23 yd^2
<u>Answer-</u>
<em>A. Brandon’s sound intensity level is 1/4th as compared to Ahmad’s.</em>
<u>Solution-</u>
Given that, loudness measured in dB is

Where,
I = Sound intensity,
I₀ = 10⁻¹² and is the least intense sound a human ear can hear
Given in the question,
I₁ = Intensity at Brandon's = 10⁻¹⁰
I₂ = Intensity at Ahmad's = 10⁻⁴
Then,



It would be K = -6j . I hope this helped you!
Answer:
1) 102
2) 62
Step-by-step explanation:
12 + 5 + 3² × 10 - 5
12 + 5 + 9 × 10 - 5
12 + 5 + 90 - 5
17 + 90 - 5
107 - 5
102
(12+5) + 3² × (10 - 5)
(17) + 9 × (5)
17 + 45
62
Answer:
1584/7 in² ≈ 226.3 in²
Step-by-step explanation:
Given,
- Radius R = 3 in
- Height H = 8 in
- Volume V = ?
We know that,
Volume(Cylinder) = πr²h
Substitute values,
Taking π as 22/7
- 72*22/7
- 1584/7 ≈ 226.3 in²
