Answer:
Solution:
the boat's speed in still water: x
The speed with current: (x+3)
The speed against current: (x-3)
The equation is
3(x+3) = 4(x-3)
x = 21 mph
The distance = 3*(21+3)= 72 miles
I choose (A)
Step-by-step explanation:
The gcf of 9 and 18 is 18
I’m not an expert at this but my guess is 45 degrees. Can you let me know what the correct answer was?
Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
Answer:
$2,651
Step-by-step explanation:
The first step is to find what 1.5% of $2,600 is.
Secondly, divide 2600 / 100 = 26
Finally, multiply 26 by 1.5 = 39.
Add 39 and 12 to 2600 = $2,651.00 total earnings for the month.
