Alice buys some inexpensive bracelets and necklaces as party favors for her jewelry showing. She pays $8 for each necklace (N) a
nd $7 for each bracelet (B). She spends less than $120. Which inequality models this situation? A) 7B + 8N ≤ 120
B) 7B + 8N > 120
C) 7B + 8N ≥ 120
D) 7B + 8N < 120
The total amount of the bracelets and necklaces is less than $120, so if you add the price of each necklace ($8) and the price of each bracelet ($7), it will be <$120.
If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula 3 V_cone = pi r^2 h Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi
Four significant is an answer because if 0 is the extreme right of decimal place it is significant and if 0 lies between two significant figure than it is significant like 1.020 is 4 sifnificant and 100 is 1 significant figure
