Answer is 380 inches squared. The bottom side is 10x10 which is 100, then all 4 sides are 10x7 which is 70, but you have to multiply that by 4 so it becomes 280. Then you add 280 and 100, the final answer is 380in^2
When it means linear you have what inter acts with each standerd
1) If you round 14.567 to the tenths place, the answer is 14.6, ie., don't put in the trailing zeros because they would give a false sense of accuracy.
2) 35/100 is 0.35 and so is 3/10 + 50/1000. The latter boils down to 0.3 + 0.05.
3) Correct. The 4 in 476907 has the 100000 unit, and the 4 in 253491 has the unit 100. The factor to get from 100 to 100000 is 1000.
4.1) 21532.41. Every digit is presented with its unit, so you could also rewrite this as a big addition:
20000
1000
500
30
2
0.4
0.01
------------- +
21532.41
4.2) Divide by ten = move the decimal point to the left. Answer a.
5) Numbers that are smaller than 4.5 can be found by just looking at the numbers up to and including first tenth. If that is smaller than 4.5, they go in the left box. So 4.4999999999 is smaller, despite all the 9's.
Same for bigger than 4.5. The additional digits can't make it smaller...
4.8, 4.75, 4.6 and 4.89 are bigger, the rest is smaller.
Answer:
Area: 360 cm
Perimeter: 44 cm
Step-by-step explanation:
To calculate the area, you must multiply the length x width.
If you need help calculating the perimeter too, just add all your lengths and widths together twice.
if one customer shows up, and she buys one song, that's $1.29, if she doesn't buy anymore, then that's the charge.
the first song is always at a full price, and after that, to encourage buying, the next ones are just 99 cents, let's see how it goes after a few songs purchases.
1 song.........................$1.29
2 songs.......................$1.29 + 0.99(2)
3 songs.......................$1.29 + 0.99(3)
4 songs.......................$1.29 + 0.99(4)
c songs.......................$1.29 + 0.99(c)
s(c) = 1.29 + 0.99c.
