Answer:
Step-by-step explanation:
2a.x=10+5
b. x=11-7
C. x=5*2
-2 and+2 =0
1/2 -3/2= -2/2 or -1
7-1=6
Answer:
180
Step-by-step explanation:
Base x Height
So 9 x 20 to get 180
Total volume is volume of cylinder+volume of cone
Volume of cylinder=pi*r^2*h
V=pi*6^2*14
V=1582.56
Volume of cone=pi*r^2*h/3
V=pi*6^2*6/3
V=226.08
1582.56+226.08=1808.64 or 1808.6 cubic inches
Interest=1250-880=370
I=PRT
P=principal
r=rate in deicmal
t=time in years
1 month so t=1/12
P=880
I=370
370=880*r*1/12
370=220/3r
times both sides by 3
1110=220r
divdie both sides by 220
5.04545=r
505% interest
