Mass of freight train: 9.98 • 106
= 1057.88 kg
mass of aircraft carrier: 7.3 • 107
= 781.1 kg
difference: 1057.88 - 781.1
= 276.78 kg
= 2.7678 x 10^2
Answer:
A = 108 in.²
Step-by-step explanation:
The figure can be decomposed into 3 rectangles.
✔️Area of rectangle 1 = L*W
L = 8 in.
W = 6 in.
Area = 8*6 = 48 in.²
✔️Area of rectangle 2 = L*W
L = 10 in.
W = 4 in.
Area = 10*4 = 40 in.²
✔️Area of rectangle 3 = L*W
L = 5 in.
W = 4 in.
Area = 5*4 = 20 in.
✔️Area of the irregular figure = 48 + 40 + 20 = 108 in.²

Answer:
$17.97
Step-by-step explanation:
It should be no surprise that the total cost is the sum of the costs of the items being purchased.
We can add the costs of repeated items into the sum several times, or we can use multiplication to find their cost. Most folks use multiplication to find the sum of repeated numbers.
milk + strawberries + bananas
= $3.49 + 2×$4.99 +6×$0.75
= $3.49 +9.98 +4.50
= $17.97

<em>Additional comment</em>
If you're paying attention, you see that this is what happens at the cash register every time you buy something at a store.
The average rate of change of the population from 2007 to 2012 is
which is to say that every five years you can expect 29 more visitors.
So if there were 607 visitors in 2010, then you could expect around 607+2*29=665 visitors in the year 2020.
Answer:
6%
Step-by-step explanation:
<em>To solve this you need to subtract 607000 by 572000 to see how many people in the population decreased.</em>
607,000- 572,000= 35,000
Then you put 35,000 over 607,000
also you need x over 100
35000/607,000 x/100
Then do cross product property
35,000*100=3,500,000
607,000* x= 607,000x
3,500,000= 607,000x
Then do 3,500,000 divided by 607,000
You get 5.76%
Round to the nearest percent and get 6%
