Answer:
28 ft
Step-by-step explanation:
Given,
The ratio of the longer side of a rectangle to its shorter side=4:3
It is said that the length of the shorter side is 21 ft.
Let the longer side be x.
Then,
4:3=x:21
or,4/3=x/21
or,x=(4*21)/3=28 ft. [ANS]
Answer:
Q = 132
P = 48
Step-by-step explanation:
Angles R + S = 180, which means
(5x + 3) + (14x + 6) = 180
19x + 9 = 180
19x = 171
x = 9
so
R = 5x + 3 = 5(9) + 3 = 48
S = 14x + 6 = 14(9) + 6 = 132
Q = 180 - R = 180 - 48 = 132
P = 180 - Q = 180 - 132 = 48
Answer: 5:00 PM
Step-by-step explanation:
let x = number of hours
280 = 80x + 60x
280 = 140x
2 = x
2 hours after 3:00 PM is 5:00 PM.
