Answer:
1.62m^2
Step-by-step explanation:
From the problem statement, the scale of the drawing is
1cm:45cm (meaning that 1cm on the drawing represent 45cm in reality ofr actual)
first,let us convert 20cm to the actual drawing
20cm in actual will give 20*45=900cm
to meters =900/100= 0.9m
Secondly let us convert 40cm to the actual drawing
20cm in actual will give 40*45=1800cm
to meters =1800/1000= 1.8m
Now we can calculate the actual area in meters we have
area= 0.9*1.8
area= 1.62m^2
Since its out of 15 marbles all together and all you need to find is the probability of 3 blue marbles you would have to divide 3 by 15. The outcome would be 0.2 or in your case... B. - 0.20
Answer:
yee
Step-by-step explanation:
Answer:
D. 28 feet
Step-by-step explanation:
a²+b²=c²
45²+b²=53²
2025+b²=2809
b²=784
=
b=28
46=12.5+.25x
33.5=.25x
x=134
Final answer: 134 miles
