This is a very good question to know about. People who make tests really like it.
The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.
The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???
t = d/r
t = 260/8
t = 32.5 hours.
Thats 32 1/2 hours.
Answer:
90°
Step-by-step explanation:
Actually the question should be AC is tangent to circle B at point C. What is the measure of angle BCA.
AC is tangent and BC is radius.
Radius is perpendicular to the tangent.
Therefore,
measure of angle BCA = 90°
Step-by-step explanation:
2 _|_20, 10, 50
5 _|_ 10, 5, 25
1 _|_ 2, 1, 5
Further, it is not divisible.
So, LCM = 2×5×2×5
LCM = 100 is the answer.
Hope it helps :)
Answer:
x = (y +2)/3
Step-by-step explanation:
y= 3x-2
y+2=3x
x=(y +2)/3
Answer:
$1,440
Step-by-step explanation:
1,200 / 10 = 120. 120 is 10%. So this means that 5% is $60. 60 x 4 = 240.
1,200 + 240 = 1,440
