Answer:
CM = 4
Step-by-step explanation:
set CM=x and BM=y AM= 7-y
right triangle BMC: x² = 5² - y² = 25 - y² ... (1)
right triangle AMC: x² = (4√2)² - (7-y)² = 32 - 49 +14y - y² = -17 + 14y -y² ...(2)
(1)-(2): 0 = 42 - 14y
14y = 42
y (BM) = 3
x² (CM²) = 25 - 3² = 16
x (CM) = 4 (height is positive)
The number that should be added on both is 7.
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)
PLS MARK BRAINLIEST!!!
X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
