There is no question in Part A, but i do what i can.
Part A.
We know that:
n - number of <span>packets of crackers
p -</span> <span>number of packets of pretzels
p = 2n+9
s - </span><span>number of packets of peanuts
s = 3p = 3(2n+9) = 6n+27
So:
There are 42 </span><span>packets of crackers, 93 </span><span>packets of pretzels and 279 packets of peanuts.
Part B.
x - number of rows with exactly 2 </span><span>passengers
y </span>- number of rows with exactly 3 <span>passengers
and:
There are </span><span>12 rows with exactly 2 passengers and 36 rows with exactly 3 passengers.</span>

Answer:
15.95 feets
Step-by-step explanation:
Given that:
Angle of elevation = 62°
Using trigonometric relation :
Tanθ = opposite / Adjacent
From the drawing attached :
Opposite = 30 feets
Distance between girl and lighthouse = d
Tan 62 = 30 / d
1.8807264 * d = 30
d = 30 / 1.8807264
d = 15.951283
d = 15.95 feets
The amount of water left = 21.3 gallons.
We have a leaking pond which looses 18 gallons of water in 34 hour.
We have to determine how many gallons of water will be left after 41 hours.
<h3>What do you understand by gallon?</h3>The gallon is a unit of volume in imperial units and United States customary units.
I gallon = 231 cubic inches = 3.785411784 liters.
According to question, we have -
Amount of water lost by the pond in 34 hours = 18 gallons
Therefore -
Amount of water lost by the pond in 1 hour =
So, the amount of water loosed by the pond in 41 hours = = 21.3
Hence, the amount of water left = 21.3 gallons.
