Answer:
38% order a chicken dinner
Step-by-step explanation:
40% order tacos. 50% of 40% order chicken tacos. 50% of 40% = 0.5 * 0.4 = 0.2 = 20% order chicken tacos.
60% order fajitas. 30% of 60% order chicken fajitas. 30% of 60% = 0.3 * 0.6 = 0.18 = 18% order chicken fajitas.
20% + 18% = 38% order a chicken dinner.
The mathematical name for a can of soup is a cylinder.
D=# of tickets sold at the door
a=# of tickets sold in advance
3a+5d=2630
d=a+30
3a+5(a+30)=2630
8a+150=2630
8a=2480
a=310
d=340
310 tickets were sold in advance and 340 tickets were sold at the door.
59 is a "prime number". It has no factors except ' 1 ' and itself.
