Answer:
Step-by-step explanation:
density is mass divided by volume, so 25g divided by 10 cm = 2.5 g
Product A would be a better deal but only by one cent.
Answer:
9,240
Step-by-step explanation:
For the first number, there are 22 numbers available to choose from. For the second number, there are 21 numbers available, since the first number cannot be the same as the second number. And for the last number, there are 20 remaining numbers to choose from. So, there are 22*21*20=9240 possible sequences.
Answer:
7
*Subtract 12-7*
Step-by-step explanation:
Step-by-step explanation:
25)
(x + 96) + (x + 96) = 180° (interior angles)
2x + 192 = 180°
2x = 180° - 192°
2x = - 12°
x = - 12°/2
x = - 6°
Therefore
x + 96 = - 6+96 = 90°
26)
(20x + 5) + (24 x - 1) = 180° (interior angles)
44x + 4 = 180°
44x = 180° - 4°
44x = 176°
x = 176°/44
x = 4°
Therefore
20x + 5 = 20*4+5 = 80+4 =84°
27)
6x = 5x + 10 (corresponding angles)
6x - 5x = 10
x = 10
Therefore
6x = 6* 10 = 60°
28)
(x + 109) + (x + 89) = 180° (interior angles)
2x + 198 = 180°
2x = 180° - 198°
2x = - 18°
x = - 18°/2
x = - 9°
Therefore
x + 89 = - 9+96 = 87°
