Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph
Answer:
n=14/9
Step-by-step explanation:
3/4n+2/3=11/6
3/4n=11/6-2/3
3/4n=11/6-4/6
3/4n=7/6
n=(7/6)/(3/4)
n=(7/6)(4/3)
n=28/18
simplify
n=14/9
Direct variation:
y - the distance, x - the time
The object falls 144 feet in 3 seconds.
The object falls y feet in 17 seconds.
In 17 seconds the object will fall 4624 feet.
Answer:
Yes.
Step-by-step explanation:
We know <S is congruent to <U. line segment ST is congruent to line segment UT. Also, the line going through T( line segment RV) makes 2 congruent angles. <STU and < UTV are congruent. So triangle RST is congruent to triangle VUT by ASA (angle side angle.)
