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.
The sum of two consecutive even integers is a+(a+2) and divided by four is
(a+(a+2))/4 = 189.5
(2a+2)/4 = 189.5
2a+2 = 189.5 * 4
2a+2 = 758
2a = 758 - 2
2a = 756
a = 756/2 = 378
first number is a = 378
second number is a+2 = 378+2 = 380
the answer is
30 x 5 + 9 x 5
For the 2017-2018 school year, the average costs for one year of education is:
Tuition/Fees: $4,391
Living Costs: $10,406
Books/Supplies: $1,724
Transportation: $2,313
Other Expenses: $3,025
With the given 7% inflation rate, the average cost will increase for the next session (2018-2019).
Hence, for year 2017-2018 the total expense will be sum of all the given costs.
= $4,391 + $10,406 + $1,724 + $2,313 + $3,025
= $21,859
You are required to find the weight of each eggplant
The weight of each eggplant is 5/4 pounds
Let
Number of eggplant = 3
Total <em>Weight</em> of eggplant = 3 3/4 pounds
Weight of each eggplant = Total Weight of eggplant ÷ Number of eggplant
= 3 3/4 ÷ 3
= 15/4 ÷ 3
= 15/4 × 1/3
= (15 × 1) / (4 × 3)
= 15/12
= 5/4 pounds
Weight of each eggplant = <em>5/4 pounds</em>
