Answer:
Step-by-step explanation:
the first one is not proportional, and the second one is proportional
the answer would be y is 5 times x.
hope this helped!
4/8 equals 1/2 because if u go down a number line and 4/8 will be in the middle so its 1/2 or u could divide bye 4
Answer:
B) 16 ft, 10.5 in
Step-by-step explanation:
There are a few different ways you can work this. Since we want to know the difference between length and heigh of the model and we are given skull length of the model, it makes a certain amount of sense to find the corresponding measurements of the actual skeleton.
The actual skeleton's length was 40 ft and its height was 13 ft, so the difference between these dimensions is ...
40 ft - 13 ft = 27 ft
The actual skull is 5 ft long, so the difference is ...
(27 ft)/(5 ft) = 5.4
times the length of the skull.
The same ratio will apply to the model, so the difference between the model height and model length is 5.4 times the length of the model skull:
desired difference = 5.4 × 3 ft 1.5 in = 16.2 ft + 8.1 in
= 16 ft 10.5 in
