Answer:
Yes
Step-by-step explanation:
The formula for area of a triangle is A = (1/2)bh,
For the first triangle we can leave it in general terms, so it's area is
A = (1/2)bh, depending on what b and h are, but it doesn't matter here...
The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is
A = (1/2)(2b)h, which simplifies to
A = bh
Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
Answer:
150.51 dB
Step-by-step explanation:
Data provided in the question:
decibel level of sound at 161 km distance = 180 dB
d₁ = 161 km
d₂ = 4800 km
I₁ = 180 db
The formula for intensity of sound is given as:
I = 
and the relation between intensity and distance is given as:
I ∝ 
or
Id² = constant
thus,
I₁d₁² = I₂d₂²
or
therefore,
I = 
or
I = 
or
I = 20 × (-1.474)
or
I = -29.49
Therefore,
the decibel level on Rodriguez Island, 4,800 km away
= 180 - 29.49
= 150.51 dB
Answer: 5.39 hours
Step-by-step explanation:
For Jill:
Number of hours used = 8.4 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/8.4 = 4.7619
For Maria:
Number of hours used = 15 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/15 = 2.6667
We then add the number of bushels of apples picked per hour for both of them together. This will be:
= 4.7619 + 2.6667
= 7.4286
If they worked together, the hours they'll take to pick 40 bushel of apples will be:
= 40/7.4286
= 5.39 hours
