Answer: it will take 9 days
Step-by-step explanation:
The water level was initially at 34feet it was receding at the rate of a foot per day. The rate at which it was receding is linear, thus, it is in an arithmetic progression. The formula for the nth term of an arithmetic progression is expressed as
Tn = a+(n-1)d
Where
a is the first term if the sequence
d is the common difference
n is the number of terms.
From the information given,
a = 34 feet because it is the initial height
n is the number of days it will take to get to 26 ft
d = -1 because it is decreasing by 1 foot per day.
Tn = T26 = 26 feet. Therefore, the equation will be
Tn = 34 -1(n-1)
To find for T26,
26= 34 + (n - 1)-1
26 - 34 = -n + 1
n - 1 = 8
n = 8 + 1 = 9
5 hours if you convert 180 kilometers to meters its 180,000 meters. 180,000 meters time 5 is 900,000
1st:
You would multiply 12 x 16 because that's the total area.
2nd:
Then you would multiply 10 x 12 because that's the amount you're subtracting from the total area.
3rd:
(12 x 16) - (10 x 12) =
192 - 120 =
A. 72 ft2
Answer:
$618.80
Step-by-step explanation:
If the tablet is on sale for 15% off, you pay 85% of the original price.
85% of $700 is
700(0.85) = $595
You pay 4% sales tax on $595, which is
$595(0.04) = $23.80
The total cost you pay is $595 + $23.80 = $618.80
