Answer:
y = x/3 + 10
Step-by-step explanation:
Let y be the number of minutes the flight takes
She can take off 10 minutes later than expected. She will be able to travel at a speed three times than expected.
Let her expected speed be s, therefore, she can travel at 3s.
x = number of minutes the flight was expected to take.
In terms of distance and speed:
x = d / s ______(1)
where d = total distance traveled
The time for the flight (minus waiting time) is now the division of the distance she traveled and her speed, i.e.:
t = d / 3s
From (1):
=> t = x / 3
The time she spent waiting is 10 minutes.
Therefore, the total time that the flight takes (plus waiting time) is:
y = t + 10
=> y = x/3 + 10
Since the first number sign is a negative its A
You would do vide the numbers
Ex: a sloth travels 5 ft every 10 minutes. you would divide the numbers and the answer would be 2ft/min
which would be 2 feet per minute
Step-by-step explanation:
1) = 4ab
2) 12a2b
3) 8ab2
4) 6ab2
5) 12abc
6) 6ab2c
7) 16a2bc
8) 27abc
Easy peasy
a circle centered at the origin is form
x^2+y^2=r^2
r=radius
point (5,-12) is on it
sub to find r^2
(x,y)
(5,-12)
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
sqrt both sides
13=r
the radius is 13
