Answer:
1st one is yes
Step-by-step explanation:
the other two im not sure about
Need the choices cant really answer your question
351 because 293 multiplied by 3 = 879, and 1230 - 879 = 351
1.
In line with the test each person who came into interaction
with the infected person will become infected also. With this information, the
calculation would be: 9 people each day for 7days would be equivalent to 9 x 7
which equals 63 people.
2.
Here were 7 other people in the experiment if patient
zero is left out. If each person intermingled with 6 different people every day
in 7 days then the calculation would be: 7 people infected x 6 new people = 42
infected people each day
42 new people every day x 7 days = 294
infected persons.
Pi = 3.14
2*3.14 = 6.28
4*3.14 = 12.56
area = pi [ C/ (2pi)] ^2
C= circumference
area of small = 3.14 (6.28/6.28)^2 =3.14
area of regular = 3.14 (12.56/6.28)^2 = 12.56
12.56/3.14 = 4
The regular pancake is 4 times the area.
