Genes, "characteristic of the offspring" (google web)
Answer:
6/8
Step-by-step explanation:
Change 1/2 into 2/4
2/4 +1/4 = 3/4 =6/8
M<APB + m<BPC = 90 complementary angles
m<FPB + m<BPC = 180 linear pair
m<APB = m<EPD vertical angles
m<FPD = m<APC right angles are congruent
m<EPC + m<EPF = 180 linear pair
m<BPC = m<EPD vertical angles
Answer:

Step-by-step explanation:
Answer:
The jetski is 2.28 dB loud when the person is 41 feet away.
Step-by-step explanation:
Loudness (L) ∝ 1 / Distance² (d²)
Introduce a constant 'K'
L = K (1/d²)
L = K/d²
K = Ld²
Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud
∴ d = 8 ft , L = 60 db
K = 60(8²) = <em>3840</em>
How loud is the jetski when the person is 41 feet away?
Distance is now 41 ft
since: L = K/d²
∴ L = 3840 / 41²
L = 3840 / 1681
L = 2.28 db
