You can use the Ruffini's rule. The answer using this method is,
And you can see that the multiplicity of the zero x=-4 is 2, and the multiplicity of the zero x=+3 is 1.
Answer:
31
Step-by-step explanation:
Here the trick is to perform the indicated operations in the correct order. Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.
Doing the work inside parentheses first:
(3 × 22) ÷ 6 + [28 – (4)2] => (66) ÷ 6 + [28 - 8], or
(66) ÷ 6 + [28 - 8] => 11 + [20], or 31
Ok so basically, the number of student tickets is 3x, where x=the number of adult tickets sold. And we know that s(for student tickets)+x=480 total tickets sold. So if we replace s with 3x we have 3x+x=480, or 4x=480. We divide by 4 and get x=120, which is the amount of adult tickets sold.
Hey there! :)
(1) Change to decimal and multiply by the number you need to find the % of
75% as a decimal = 0.75
0.75 × 28 = 21
Your answer is 21

(2) Circumference = π · diameter
To find diameter, divide circumference by π
Circumference = 37.68
37.68 ÷ π = 11.99 = 12
The diameter is 12
Hope this helps :)
