Answer:
277 848 newspapers.
Step-by-step explanation:
Find out how much newspaper he drops for 4.3 miles.
1/4 = 0.25
4.3 miles ÷ 0.25 = 17.2
= 17
17 x 22.7 = 385.9
(Newspapers be dropped a day)
1 week of dropping newspapers = 385.9 x 3 = 1157.7
1 month of dropping newspapers = 1157.7 x 4 =
4630.8
1 year = 12 months
5 years = 12 x 5 = 60 months.
5 years/60 months of dropping newspapers = 4630.8 x 60 = 277 848
Tommy dropped 277 848 newspapers.
Answer:
36 cm^2.
Step-by-step explanation:
The area is half the product of the lengths of its diagonals.
(PA)(LY) = (12cm)(6cm)
= 72 cm
72cm ÷2= 36 cm^2
Therefore the area is 36 cm^2

Step-by-step explanation:
<u>Step 1: Define</u>
14.3 > 5(z - 2) - 2.1
<u>Step 2: Solve for </u><em><u>z</u></em>
- Distribute 5: 14.3 > 5z - 10 - 2.1
- Subtract: 14.3 > 5z - 12.1
- Add 12.1 on both sides: 26.4 > 5z
- Divide 5 on both sides: 5.28 > z
- Rewrite: z < 5.28
Here we see that any value <em>z </em>smaller than 5.28 would work as a solution to the inequality.
Range is subtracting the biggest value and the smallest value of the data. For this set of data the range is:
9 - 3 -------------------------------> 6
Mode is the number that appears most often. In this set of data no number appears more than twice so mode is not applicable
Median is the middle of the numbers when ordered from least to greatest. For this set of the data the median is:
3 4 6 8 9
4 6 8
6
Mean is adding all the number together then dividing the sum by how many numbers there are in the data. For this data the mean is:
(3 + 4 + 6 + 8 + 9) ÷ 5
(30) ÷ 5 ------------------------------------> 6
As you can see the range, median, and mean all have the value of 6
Hope this helped!
