Answer:
10.75 cm^2
Step-by-step explanation:
1. Area of semicircle, A= (pi x R^2) divided by 2
2. A= (3.14 x 5^2) divided by 2 = 39.25
3. Area of rectangle, A= l x w
4 A= 10 x 5 = 50
5. subtract
6. 50 - 39.25
7. 10.75
Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position
There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C
Multiply those values out: 9*8*7 = 72*7 = 504
There are 504 ways to pick three people from a pool of nine.
Answer: 504
Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer
Age of martin is 38 and that of sherwin is 9
The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are <span>101,949 fewer people than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people
Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = </span>351,875 + 249,926 = 601,801 people
Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people
