Would you like me to show the steps, or tell you the answer?
put a 1 under the 13, so it is 13/1, and 5 5/6, turn it into an improper fraction by multiplying 5x6=30. then 30+5, which is 35. so just keep the denominator, which would be 35/6. so you would have 13/1 - 35/6. you need the same denominator, so see what both 1 and 6 would fit into. which is 6. so 13x6 which is 78, so 78/6 - 35/6, so 78-35 is 43. so 43/6, then simplify, which is 7 1/6
Let R = 250 ft. & r = 200 ft.
Now, Area of Gravel Path =
= πR² - πr²
= π(R²-r²)
Area of Gravel Path =
π ( 250² - 200² )
π ( 62500 - 40000 )
π ( 22500 )
Taking π as 3.14
![π \times 22500 \\ 3.14 \times 22500 \\ \frac{314}{100} \times 22500 \\ 314 \times 225 = 70650 \: f {t.}^{2}](https://tex.z-dn.net/?f=%CF%80%20%5Ctimes%2022500%20%5C%5C%203.14%20%5Ctimes%2022500%20%5C%5C%20%5Cfrac%7B314%7D%7B100%7D%20%5Ctimes%2022500%20%5C%5C%20314%20%5Ctimes%20225%20%3D%2070650%20%5C%3A%20f%20%7Bt.%7D%5E%7B2%7D%20)
As Option is nearest to our answer,
that means it will be right.
So,
Answer will be (c) 70686 ft.²
Every point in the unit circle is identified either by its coordinates
or by the angle it forms with the x-axis,
.
The trigonometric functions associate with every angle
and the correspondant
coordinates the two values
![\cos(\alpha)=x,\quad\sin(\alpha)=y](https://tex.z-dn.net/?f=%5Ccos%28%5Calpha%29%3Dx%2C%5Cquad%5Csin%28%5Calpha%29%3Dy)
This procedure can be done for every angle
, so you don't have to work with acute angles only.
Answer:
-94
Step-by-step explanation:
2( − 6) − 72 − (13 − 3)
PEMDAS
Parentheses first
2( − 6) − 72 − 10
Then multiply and divide from left to right
-12 -72-10
Then add and subtract from left to right
-94
