Answer:
87.6 m²
Step-by-step explanation:
9x9=81
2x1/2x2.2x3=6.6
81+6.6=87.6
Velocity (against wind) = 2,688 km / 4 hr = 672 km/hr
Velocity (with wind) = 3,208 km / 4 hr = 802 km/hr
psa means plane velocity in still air
ws means wind speed
psa -ws = 672
psa +ws = 802 We add both equations and get
2 psa = 1,474
plane velocity (in still air) = 737 km/hr
psa +ws = 802 so that means
wind speed = 802 -737 = 65 km/hr

Answer:
37π/180
Step-by-step explanation:
0.75 = 37º and in radions thats To convert degrees to radians, multiply by π/180°, since a full circle is 360° or 2/π
radians.
37°⋅ π/180°
radians
Combine 37
and π/180
.
37π/180
radians
Answer:
15 dogs
12 cats
Step-by-step explanation:
Let's call the number of cats c, and the number of dogs d.
4d=5c
c+d=27
4c+4d=108
4c+5c=108
9c=108
c=12
d=27-12=15
Hope this helps!
Answer: $804.75
Step-by-step explanation:
The Social Security (OASDI) withholding rate is the gross pay times 6.2% of the maximum pay level for that particular year while the Medicare withholding rate is the gross pay times 1.45 %.
Laura has a job that pays $4,625 monthly. Her Medicare will be:
(1.45% of $4,625) × 12
= 0.0145 × $4625 × 12
= $804.75
