Answer:
t = 6/5
Step-by-step explanation:
Step 1: Define
k(t) = 10t - 19
k(t) = -7
Step 2: Substitute and Evaluate
-7 = 10t - 19
12 = 10t
t = 6/5
Answer:
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
Step-by-step explanation:
For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
