Answer:
34 mph and 68 mph respectively
Step-by-step explanation:
Step one:
given data
let the speed of the first truck be x mph
and the speed of the second truck be 2x mph
time taken = 6 hours
total distance = 204 miles
Step two:
from speed = distance/time
distance= speed*time
hence
2x*6-6x= 204
12x+6x= 204
6x= 204
divide both side by 6
x= 204/6
x=34 mph
The second truck was moving at
=2x
=2*34
=68 mph

Answer:
Step-by-step explanation:
The given sequence of numbers is increasing in geometric progression. The consecutive terms differ by a common ratio, r
Common ratio = 6/3 = 12/6 = 2
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = 3
r = 2
The function, f(n), representing the nth term of the sequence is
f(n) = 3 × 2^(n - 1)
Answer:
X = 18
Step-by-step explanation
The shown figure of isosceles triangle can be drawn as :
Now it become a right angle triangle
From right angle triangle rule
hypotenuse² = Perpendicular² + Base²
i.e 15² = 12² + (
or 15² - 12² =
or 225 - 144 =
or 81×4 = x²
or x= 
i.e X= 18 Answer
