Answer:
38/3
Step-by-step explanation:
s is the midpoint of RT
so, RS = ST
5x + 7 = 8x -31
7+31 = 8x-5x
38= 3x
x= 38/3
Answer:
5) 140.8m^2 6) 360in^2
Step-by-step explanation:
5.
6.4 x 6.4 = 40.96
(7.8 x 6.4) ÷ 2 = 24.96
24.96 x 4 = 99.84
99.84 + 40.96 = 140.8m^2
6.
12 x 10 = 120in
13 x 10 = 130in
5 x 10 = 50in
(12 x 5) ÷ 2 = 30in
30 x 2 = 60in
60 + 50 + 130 + 120 = 360in^2
3 days = 72 hours + 12 hours = 84 hours
12600 watt hours / 84 hours
= 150 watt hours / 1 hour
It’s asking how many watt hours consumed per day. We know 150 watt hours per hour so multiply that by 24 because 24 hours in a day
= 3600 watt hours per day
