2x + 4 = 3x - 10
-2x and +10 to both sides
14 = x
the answer is x = 14
<u>Answer</u>
161.06
<u>Explanation</u>
We can get the area of the shaded part by using the formula;
Area = θ/360 πr²
Where θ ⇒ subtended angle
π = 3.142
r ⇒ radius
First 1.25 radians in to degrees.
π radians= 180°
1.25 radians = (180×1.25)/π
= 71.62°
The angle on the shaded part is 360 - 71.62 = 288.38°
Area = (288.38/360)×π×8²
= 0.8 ×3.142 × 64
= 161.06
Answer:
Step-by-step explanation:
The formula to use is the nCr combination formula
n C r = (n!)/(r!*(n-r)!)
where the exclamation marks indicate factorial notation
Plug n = 10 and r = 2 into the formula
n C r = (n!)/(r!*(n-r)!)
10 C 2 = (10!)/(2!*(10-2)!)
10 C 2 = (10!)/(2!*8!)
10 C 2 = (10*9*8!)/(2!*8!)
10 C 2 = (10*9)/(2!)
10 C 2 = (10*9)/(2*1)
10 C 2 = 90/2
10 C 2 = 45
Answer: 45
