area square: 9in×9in = 81in
area triangle: [9in×(13in-9in)]/2
= (9in×4in)/2
=36in/2
=18in
green area: 81in+ 18in= 99in
Answer:
3 3/5 gallons per hour
Step-by-step explanation:
3/5 times 6 equals 18/5
18/5=3 3/5
The total length of the trip is the number of miles in the trip
The total length of the trip is 974 miles
<h3>How to determine the total length?</h3>
The given parameters are:
- Proportion of sleep = 21%
- Distance awake = 711 miles
If Taylor sleeps for 21% of the trip, then Taylor was awake for 79% of the trip
Represent the total length of the trip with T.
So, we have:
73% * T = 711 miles
Divide both sides by 73%
T = 974 miles
Hence, the total length of the trip is 974 miles

4•4 -1•1 = 16-1 = 15 square inches
The sum of the first 7 terms of the geometric series is 15.180
<h3>Sum of geometric series</h3>
The formula for calculating the sum of geometric series is expressed according to the formula. below;
GM = a(1-r^n)/1-r
where
r is the common ratio
n is the number of terms
a is the first term
Given the following parameters from the sequence
a = 1/36
r = -3
n = 7
Substitute
S = (1/36)(1-(-3)^7)/1+3
S = 1/36(1-2187)/4
S = 15.180
Hence the sum of the first 7 terms of the geometric series is 15.180
