Answer 1

Answer: for the second one, remember LW=are for fiding the area of the base,
for cone, base=circle, so therfor V=HB/3, and B=circle=pir^2, so V=(1/3)(hpir^2)
h=17
r=6
V=(1/3)(17(3.14)6^2)
V=17(3.14)12
V=640.56
rond tenth
V=640.6
B

The value of Maggie's car decreased by 25% since last year, when she bought it. If the car is now worth $18,000.00, how much was the car worth when she bought it?A.
$25,714.29
B.
$24,000.00
C.
$22,500.00
D.
$19,500.00

Answers

B. 24,000.
The car was worth 24,000 when she bought it.

25% = equivalent of the decreased value
18,000 = net of the decrease value

Original value = 18,000 / (100% - 25%)
= 18,000 / 75%
Original value = 24,000

Decrease value = 24000 * 25%
= 6000

Net Value = 24,000 - 6000
= 18,000
