Answer:
is the degrees value of .
Step-by-step explanation:
We are given the following details about the angle :
It is know that the relation between radians and degree units is as follows:
We can use simply use unitary method to convert radian value of to degrees.
Hence,
(a + 1)(a² + 2a + 1)
= a(a² + 2a + 1) + 1(a² + 2a + 1)
= a³ + 2a² + a + a² + 2a + 1
= a³ + 3a² + 3a + 1
Answer: b
Answer:
1 notebook=$30.7
1 thumb drive =$12.2
Explanation:
Let x represent the number of notebooks and y represent the number of thumb drives.
4x+5y = $116 ................1
2x+3y = $68..................2
4x+2x=$116+$68
6x=184
Therefore, the cost of each notebook=30.66
=$30.7
2x+3y=$68
2(30.7)+3y =$68
$31.4+3y=$68
3y=$68 - $31.4
3y=36.6
Therefore, the cost of each thumb drive = $12.2
Proof
2(30.7)+3(12.2)=$68
31.4+36.6=$68.0
Answer:
13
Step-by-step explanation:
56 divided by 7 equals 8
210 divided by 10 equals 21
And if you subtract 21-8 you get 13 #helping the 3rd graders
