Answer:
Fahrenheit = 50°F
Step-by-step explanation:
Equation: F = ⁹/₅C + 32, C = 10
Plug in: F = ⁹/₅(10) + 32
Multiply: F = 18 + 32
Add: F = 50
Answer:
16
Step-by-step explanation:
12-(-4)=12+4=16
Answer:
8.
60 * 2 + 30 = 150km
225 - 150 = 75km
50km/h and 75km, so 1.30h
1.30 + 2.30 + 0.10 = 4.10h
Im not very good at english so I dont know how to explain...

1.30 - 47 = At 12.43
Answer:
why won't Ralph show 13/20 then?
Answer:
121 degrees
Step-by-step explanation:
The "arc length" formula is s = rФ, where Ф represents the central angle in radians (not degrees).
Here r = 18 ft and s = 38 ft, and so:
38 ft
s = rФ becomes Ф = ------------ = 2.111 radians
18 ft
which, in degrees, is:
2.111 rad 180 deg
------------- * --------------- = 121 degrees, to the nearest degree
