Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
Answer
The answer is 36.
Explanation:
Let the unknown number be x
x^3=x*36
or, x^3/x=36
or, x^2=36
or, x=6
.•. x=36
Domain: all real numbers
Range: y>-3
Answer:
-3
Step-by-step explanation:
-1*-1=1
2*2=4
1-4
=-3
Answer:
$230
Step-by-step explanation:
100%-20%=80%
80%=184
1%=184÷80=2.3
100%=2.3x100=$230
Hope this helps! Thanks.
