<span>So we want to know the number from which we take 25% and get 80. If the number we are looking for is x, then the equation to find that x would be: (25/100)*x=80 which says twenty five percent out of x is equal 80. So, x=(80*100)/25. And finally, x= 8000/25=320. So, 25% out of 320 is 80.</span>
Time taken for the boats to meet will be given by:
time=(distance)/(speed)
relative speed=(speed of boat A+speed of boat B)
speed of boat A=2.5 mph
speed of boat B=2(2.5)=5 mph
thus
relative speed=(5+2.5)=7.5 mph
distance=30 miles
thus
time=30/7.5=4 hours
thus the earliest they can meet is 4 hours

Step-by-step explanation:
Answer:
h = 1.4
c = 2.8
Step-by-step explanation:
For each problem, remember the special triangle side ratios then use a proportion. To solve, isolate the variable.
For the triangle with the variable h:
Since two of the angles are 45, this is an isosceles triangle. All isosceles triangles have two equal sides that are not the hypotenuse.
In a right isosceles triangle, the ratio for regular side to hypotenuse is 1 to √2.
h = √2
h ≈ 1.4
For the triangle with the variable c:
The is an equilateral triangle cut in half because the angles are 30 and 60.
The side ratio of altitude to hypotenuse is √3 to 2.
c = 2√2
c ≈ 2.8
