One square inch is equal to
. So, your box have
square inches and it costs
or
$36 to manufacture it.
I will show you a way to do 1 and then you pratice with the rest and I'll check it and help you .
This is what I would do to make it easier
1. 7:15 to 11:16 then 12:05 to 6:10
- hours are on the left side-
1 - 7:15 to 8:15
2- 8:15 to 9: 15
3 - 9:15 to 10:15
4 - 10:15 to 11:15
16 - 15 = 1
4 hours and 1 minute
worked :12:05 - 6:10
1- 12:05 to 1:05
2- 1:05 to 2:05
3- 2:05 to 3:05
4 - 3:05 to 4:05
5- 4:05 to 5:05
6- 5:05 to 6:05
10 - 5 = 5
6 hours and 5 mins
4 + 6 = 10 hours
1 + 5 = 6 mins
10 hours and 6 minutes
Step-by-step explanation:
x² + 6x + 9 = 2
(x + 3)² = 2
x + 3 = ±sqrt(2)
x = -3 ± sqrt(2)
so, B and D are correct.
control :
(-3 + sqrt(2))² + 6(-3 + sqrt(2)) + 9 = 2
9 + 2 - 6sqrt(2) - 18 + 6sqrt(2) + 9 = 2
2 = 2
correct
(-3 - sqrt(2))² + 6(-3 - sqrt(2)) + 9 = 2
9 + 2 + 6sqrt(2) - 18 - 6sqrt(2) + 9 = 2
2 = 2
correct
(3 + sqrt(2))² + 6(3 + sqrt(2)) + 9 = 2
9 + 2 + 6sqrt(2) + 18 + 6sqrt(2) + 9 = 2
38 + 12sqrt(2) = 2
wrong.
(3 - sqrt(2))² + 6(3 - sqrt(2)) + 9 = 2
9 + 2 - 6sqrt(2) + 18 - 6sqrt(2) + 9 = 2
38 - 12sqrt(2) = 2
wrong.
Answer:Takeyour time
Step-by-step explanation:
Answer:
0.41791
Step-by-step explanation:
let x be the number written to the thousandth place then,
x times thousands = 417.91
or, x = 417.91/1000
therefore, x = 0.41791
and so
0.41791 thousand = 417.91
