Answer:
1.05 x 10 to the 8th power
Step-by-step explanation:
Answer:
9.09
Step-by-step explanation:
x=speed of boat
y=speed of water current
Downstream relative speed = x+y
Upstream relative speed = x-y
Distance remains the same for both upstream and downstream.
a) Distance travelled downstream = speed x time = 3(x+y)
Distance travelled upstream = speed x time = 3.6(x-y)
b) Since both distances are equal, we can write
3(x+y)= 3.6(x-y)
3x+3y = 3.6x-3.6y
6.6y = 0,6x
x=11y: y=x/11
c) Water current has speed as 1/11 times of that of boat
In percent this equals 100/11 = 9.09%

Answer:
14
Step-by-step explanation:
Even though the triangle is "upside down"
a = (1/2)bh
b is QB = 4
h is QA = 7
a = (1/2) * 4 * 7
a = 14
