Answer:
B, 24 (second answer choice)
Step-by-step explanation:
4r+7s=23
r-2s=17
8r+14s=46
7r-14s=119
15r=165
r=11
11-2s=17..........by putting value of r in ii
-2s=17-11
2s= -6
s= -3
3r+3s=3*11+3(-3) you get this by putting values of r and s
=33-9
=24 (B)
The Answer would be y=-3x
Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
(1)
where:

r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

And therefore, by applying eq.(1) we can find the circumference of the circle:

Just pretend it’s a 3d right angle triangle and find the length of the hypotenuse.
d = sqrt(6^2 + 10^2 + 15^2) = 19
