Lateral surface are = 2( 1/2 x 11 x 11.9) + 2( 1/2 x 9 x 12.3)
Lateral surface area = 130.9 + 110.7 = 241.6 ft²
Answer: 241.6 ft² (Answer C)
15 miles 2.5 x 6 because 1/4th of an hour is 15 minutes 15 x6 = an hour and a half
Answer: b = 3
Step-by-step explanation:
4.4a-2.9a= 1.5a
6.8-7.3=(-0.5)
Ans: 1.5a+(-0.5) OR 1.5a-0.5
I=PRT
P=present amount
R=rate
T=time
basically
20+interest<u /> is more than or equal to 400
20+I<u>></u>400
minus 20 both sides
I<u>></u>380
solve
P=20
R=3%=0.03
T=?
I=PRT
380<u><</u>I=PRT
380<u><</u>20(0.03)(T)
380<u><</u>0.6T
divide both sides by 0.6
633.33333<u><</u>T
633.33 years at least
