Answer:
76.7 liters
Step-by-step explanation:
You have ...
C1×V1 = C2×V2
so ...
V2 = V1×(C1/C2) = (115 L)×(14/21) = 76 2/3 L
V2 ≈ 76.7 L
Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be 
,
Speed uphill is 
. We are told than speed uphill is 
the speed on flat ground. Therefore the speed on level ground will be 
.
From this info, we can obtain the actual speed,
on level ground as:
speed, distance and time have the relation 
so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.

Answer:
The answer to your question is x = 14.7
Step-by-step explanation:
Data
∠A = 20°
∠B = 46
a = 7
b = x
Process
To solve this problem use, the law of sines. This law states that the ratio of a side of a triangle to the sine of the opposite angle is the same for all three sides.
The law of sines for this problem is
x / sin 46 = 7 / sin 20
-Solve for x
x = 7 sin 46 / sin 20
-Simplification
x = 7 (0.719) / 0.342
x = 5.035/0.342
-Result
x = 14.7
9,11,14
the pattern is add one then add two then add three
