Answer:
Step-by-step explanation:
2) Lateral area of cylinder = 2πrh
=2*3.14*8*4
= 200.96 cm²
3) Surface area of cylinder =2πrh + 2πr²
= 2*3.14*5*10 + 2*3.14*5*5
= 314 + 157
= 471 cm²
B. Add -12x to both sides. Then divide all terms by -2. The positive 12 on the right side will be a -6 and the -42 will be a positive 21. The inequality sign is always switched whenever the equation is divided by a negative number.
Answer:
accounting=30, economics=15, only one=35
Step-by-step explanation:
a=2e
5 both
10 neither
40=a+e-5
45=a+e
45=2e+e
e=15
a=2e
a=30
