The answer is
2
Explanation
You have to do 2/3 x 3 and you do that by multiplying 2 and 3 (6/6)
Which if you split up is 3/3, 3/3 = 2
We have been given that the upstream speed is 
and the down stream speed is 
.
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is 
Hence, 
Time upstream + time downstream = 6
lcm = 10
=> 
Cross multiplying, 
x = 20 miles .. Answer.
9514 1404 393
Answer:
48°
Step-by-step explanation:
ΔACB is isosceles, so angles A and B have the same measure. The measure of angle C in that triangle is ...
∠C = 180° -2(69°) = 42°
Angle C in ΔCDE has the same measure. Angle D is the complement of that:
∠D = 90° -42° = 48°
_____
The relations we used are ...
- the sum of angles in a triangle is 180°
- base angles of an isosceles triangle are congruent
- vertical angles are congruent
- acute angles in a right triangle are complementary
Answer:
-30x^2-9x+12 all real numbers
Step-by-step explanation:
f(x) = -6x + 3 and g(x) = 5x + 4
f(x) * g(x) = (-6x + 3) * ( 5x + 4)
FOIL
= -30x^2 -24x+15x +12
Combine like terms
=-30x^2-9x+12
The domain is what numbers x can take
There are no restrictions so all real numbers
