Answer:
1201.2 in (100.1ft)
Step-by-step explanation:
A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.
First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.
Answer:
18 km/hr
90 km
Step-by-step explanation:
We know that there are
1000 m = 1 km
and
3600 s = 1 hr
We need to convert m/s to km/h
5 m 3600s 1 km 18000km 18 km
------ * ------------ * ------------ = --------------- = ------------
s 1 hr 1000m 1000 hr hr
It is 18 km/hr since the units cancel.
We want to know how far the cyclist travels
d=rt
We know the rate 18km/hr and the time = 5 hr
d = 18 km/hr * 5 hr
d =90 km
It is D. it has a negative slope and is not as steep as -3
My answer is 15 and the other person who answered is wrong because they only counted the ones visible and not the ones that are not visible as the figure is a 3d object.
