Mathematics

Answer:

(i) 120°

Step-by-step explanation:

(i)

sine 90 = 1

sine 120 = 0.87 (rounded up to two decimal places)

sine 150 = 0.5

sine 180 = 0

sine 210 = -0.5

sine 240 =  -0.87 (rounded up to two decimal places)

sine 270 = -1

sine 60 =  0.87 (rounded up to two decimal places)

So the angle x such that 90° < x < 270° that has the same sine value as 60° is 120°

Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?
kap26 [50]
<h2>Answer :</h2>

  • Error (e) = 12 - 9 = $ 3

  • assumed value (a) = $ 9

\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}

  • \mathrm{ \% \: error =\dfrac{3}{9} ×100}

  • \mathrm{ \% \: error = \dfrac{1}{3} ×100}

  • \mathrm{ \% \: error = 33.33 \%}

I Will give you 98 points if you will answer this.
Alex777 [14]
Answer: -1

Explanation: The subscript (3) under 6 has no value so 6 subscript 3 is just 6. Use BEDMAS to solve for the equation (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)

1. 6 x 2 - 24 / square root 16 + (8)
2. 6 x 2 - 24 / 4 + 8
3. 6 x 2 - 24 / 12
4. 12 - 24 / 12
5. -12 / 12
6. -1

Therefore the answer is -1.

32. The length of a rectangle measures six more than the width. The perimeter of the rectangle is 38.
Ne4ueva [31]

Answer: 12.5

You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."

subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"
