Answer:
Bc=20
Step-by-step explanation:
Sin61=BC/AC=BC/23
BC=23sin61=20
16.76 rounds off to 17
After the dot if it’s 1-4 then they it would’ve been 15
5-9 is 17
Answer:
Expand: x² + 11x + 11x + 121
Simplify: x² + 22x + 121
Step-by-step explanation:
To expand this, you can use the FOIL technique:
First terms
Outer terms
Inner terms
Last terms
(x+11)(x+11)
F - x*x = x²
O - x*11 = 11x
I - 11*x = 11x
L - 11*11 = 121
Put these numbers together (expanded) to get:
x² + 11x + 11x + 121
Put the common terms together (simplify) to get:
x² + 22x + 121
Note:
Not sure if you need this info, but (x + 11)(x + 11) is the same as (x + 11)².
The numbers need to be in the order I put them in because you are supposed to place them in order greatest to least degree.
Hope it helps!
Answer:
- 16. 3/8
- 17. 1/8
- 18. 5/18
- 19. 0
- 20. 1
Step-by-step explanation:
<u>As per the spinner we have:</u>
- Green = 1/2 - 1/16 = 7/16
- Red = 1/4
- Purple = 1/8
- Orange, blue, yellow = 1/16
<u>16. P(red, yellow, blue) = ?</u>
- P = 1/4 + 1/16 + 1/16 = 3/8
<u>17. P(orange, yellow) = ?</u>
<u>18. P(green, blue, purple) = ?</u>
- P = 7/16 + 1/16 + 1/8 = 10/16 = 5/8
<u>19. P(pink) = ?</u>
<u>20. P(red, orange, yellow, green, blue, purple) = ?</u>
- P = 1 as all possible colors selected
