Money spent by Americans last year=$1,180-6.8% of $1,180
=$1099.76
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
Answer:
70 seconds
Step-by-step explanation:
Given that;
The initial velocity 
of the bullet fired = 1120 ft/s
Initial height h = 8 feet
The expression to determine how many seconds it takes the bullet to hit the ground is:
Thus;
Replacing the value of = 1120 and h = 0 (i.e. when h =0) in the above expression; we have:
= -16t² + 1120t + 8
mulitiply through by (-)
= 16t² -1120t - 8
Divide through by 8
= 2t² - 140t - 1
The above expression forms a quadratic equation.
where;
a = 2
b = -140
c = - 1
So, by using the quadratic formula 
, we have:
= 70
Thus, the time (in seconds) it took the bullet to it the ground = 70 seconds
Answer:
h<-7/4
Step-by-step explanation:
Answer:
Step-by-step explanation:
The formula representing the the annual inflation rate r is expressed as
r = (F/P)1/n−1
Where
n represents the the number of years during which the value increases from P to F
A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. This means that
P = $800,000
F = $1,100,000
n = 6
Therefore,
r = (1100000/800000)1/6−1
r = 1.375/5 = 0.275
