Simplify 0.95x-9-1/2x(36-18y)-0.25(-3x+4.8)
iris [78.8K]

Answer: 9xy−16.3x−10.2

Step-by-step explanation:

Distribute:

=0.95x+−9+9xy+−18x+(−0.25)(−3x)+(−0.25)(4.8)

=0.95x+−9+9xy+−18x+0.75x+−1.2

Combine Like Terms:

=0.95x+−9+9xy+−18x+0.75x+−1.2

=(9xy)+(0.95x+−18x+0.75x)+(−9+−1.2)

=9xy+−16.3x+−10.2

lara31 [8.8K]
Note: 1 inch = 2.54 cm is an exact converion, while 1 mile=1.6km is only approximate.

Using conversion
1 inch=2.54 cm
1 mile = 1760*3*12 = 63360 in = 160934.4 cm 
If 1 inch = 1 mile, then 
2.54 cm : 1 mile = 1.609344 km
1 cm : 0.6336 km   (exactly), or
1 cm : 0.6 km (approximately)

Using both conversions:
1 inch = 2.54 cm : 1 mile = 1.6 km
=>
2.54 cm : 1.6 km
1 cm : 1.6/2.54=0.6299 km (approximately), or
1 cm : 0.6 km (approximately)

astraxan [27]

Answer:

5.03\frac{rad}{sec}

Step-by-step explanation:

To find the angular velocity divide the revolutions by the time

so

\frac{16}{20}=0.8\frac{rev}{sec}

Remember that

1\ rev=2\pi \ rad

Convert rev/sec to rad/sec

0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}

assume \pi=3.1416

1.6(3.1416)=5.03\frac{rad}{sec}
