Downwind DATA:
distance = 1330 ; time = 5 hrs ; rate = d/t = 1330/5 = 266 mph
---------------------------
Upwind DATA:
distance = 1330 ; time = 7 hrs ; rate = d/t = 1330/7 = 190 mph
---------------------------
Equations:
p + w = 266
P - w = 190
-------------
Subtract 2nd equ. from 1st to get:
2w = 76
w = 38 mph (speed of the wind)
Answer 38mph
Answer:
790 ft
Step-by-step explanation:
If there were 36 gondolas separated by an arc length of 21.94 ft, the circumference of the Ferris wheel was
36 × 21.94 ft = 790 ft
Answer:
x = 10
Step-by-step explanation:
4x + 3(x - 1) = 67 ← distribute parenthesis and simplify left side
4x + 3x - 3 = 67
7x - 3 = 67 ( add 3 to both sides )
7x = 70 ( divide both sides by 7 )
x = 10
2p^2 + 3p - 4 - (-2p^2 - 3p + 4) =
2p^2 + 3p - 4 + 2p^2 + 3p - 4 =
4p^2 + 6p - 8 <==
Answer:
Step-by-step explanation:
The measurement of the height is the dependent variable. The independent variable is the amount of fertilizer applied.
