Step-by-step explanation:
C. 16.4
Step-by-step explanation:
The formula to apply here is;
A=P(1+r/n) ^nt where
A=final amount
P=starting amount
r=rate of interest annually
n=number of compounding per year
t=time in years
Given ; P=$500, A=$750 , r=2.5%=0.025 , t=?,n=1
Substitute values;
A=P(1+r/n)^nt
$750=$500(1+0.025)^t
750=500(1.025)^t
750/500=(1.025)^t
1.5=(1.025)^t
log 1.5 =t log (1.025)
log 1.5/log 1.025 = t
16.4 =t

Answer:
b. – 0.4(x + 1.6) = 1.6
Step-by-step explanation:
Circumference = πd, where d = diameter
we know the wheel has a diameter of 27 inches, so the total circumference is 27π, and that's the arc length of one revolution.
there are 5280 feet in 1 mile and 12 inches in 1 foot.
so in 40 miles there are 40(5280)(12) inches.
and we also know that there are 60 minutes in 1 hour.
