Answer:
the speed of sound is 12 miles per minute
Step-by-step explanation:
To know the speed we have to divide the distance by the time because the speed of sound is constant and we have to use a formula of uniform rectilinear motion
Uniform rectilinear motion: When an object travels at a constant speed with zero acceleration it is known as uniform rectilinear motion
The distance it gives us is 1 mile and the time it gives us is 1/12 minute
v = speed
v = 1mi / (1/12 m)
v = 12 mi/m
in the result as we can see we have a whole number (12)
the speed of sound is 12 miles per minute
Using the equation A=P(1+(r/n))^nt.
n=monthly, so it's 12.
t=19 years
r=6.9% as a decimal is .069
P=47,000
.069/12=.00575
.00575+1=1.00575
nt=12*19=228
1.00575^228=3.695
3.695*47000=$173,711
Answer: $173,711

Step-by-step explanation:
Answer:
A bag of chips costs $1
A pickle costs $1.25
Step-by-step explanation:
P + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25
