Answer:
0.13 cm ( as question was posted)
13 cm ( if width was in centimeters)
Step-by-step explanation:
a = lw
4.5m = 450cm
Plug in the knowns
58.5 = l(450)
Divide both sides by 450
0.13 = l
length is 0.13 cm
----------------------------
I did the qustion as you posted it.
If you intended 4.5 <em>centimeters</em> instead of 4.5 <em>meters</em> then
58.5 = l(4.5)
divide both sides by 4.5
l = 13 cm
10 tenths in a whole.....
Answer:
The bell is 4.5 feet tall
Step-by-step explanation:
The ratio of the replicas are 1in : 0.5ft, so each inch of the model is 0.5 feet in real life.
The replicas are 9 inches tall, so you would multiply by the scale factor, 0.5 feet. You want the units to end up being feet, so you position the fractions to cancel out inches.
in x 
the inches cancel out and you are left with:
9 x 0.5 ft
Simplify.
4.5 ft
Tan is opposite/adjacent = 15/8
Sin = opp/hyp
Cos = adj,/ hyp
Use Pythagorean theorem to find hypotenuse
15^2 + 8^2 = c^2
225+64= 289
√289= c
c=17
Sin = 15/17
Cos= 8/17
