Answer:
It's C! 75%
Step-by-step explanation:
23. it increased by 12 because the difference between -4 and 8 is 12
24. 25 because 40 minus 15 is 25
26. 5 because 156 minus 96 equals 60 and 60 divided by 12 equals 5
Answer:
see explanation
Step-by-step explanation:
(1)
(a)
sin(a) =
= 
(b)
cos(a) =
= 
(c)
tan(a) =
= 
----------------------------------------------------
(2)
(a)
sin(b) =
= 
(b)
cos(b) =
= 
(c)
tan(b) =
= 
Here you have to use proportionality,
1 feet is 12 inches so 40 feets is 480 inches
Then the real locomotive is 480/16=30 times wider then the model
And then a window on the real locomotive is 30 times wider then the model..
