I don't know how you actually found a value :/
Perimeter = S1 + S2 + S3 5x^4-2x^3+x-3= (2x^4 + 2x-1) + (2x^4+2x-1) + base 5x^4-2x^3+x-3 = 2(2x^4 + 2x-1)+ base 5x^4-2x^3+x-3 - 2(2x^4 + 2x-1) = BASE 5x^4-2x^3+x-3 -4x^4-4x+2= BASE 5x^4-4x^4-2x^3-3x-1 = BASE
50 people require 4 cups of sugar 1 person will require 4/50 cups of sugar 100 people will require 4/50 x 300 cups of sugar = 24 cups of sugar 6 cups of sugar = 1 bag 1 cup of sugar = 1/6 bag 24 cups of sugar = 1/6 x 24 bag = 4 bags Therefore, 300 people require 4 bags of sugar
In order to paint 144 sq feet it will take 45 minutes In order to paint 1 sq foot it will take 45/144 minutes In order to paint 240 sq feet it will take: 45/144 x 240 minutes = 75 minutes
x^2-4x+32=0 a =1 b= -4 c= 32 4 +or- sq root (-4)^2 -4(1)(32) 4 +or- sq root 16-128 4 +or- sq root -112 you can't take the sq root of a (-) number so you can't solve this :/ How did you get 2 +or- 2 sqrt7. Perhaps I went wrong somewhere.
What exactly is a trend line? I'm thinking it would be B because they're not asking for the exact line. In fact, if it's a scatter plot there wouldn't be a perfect straight line. I think you're right. It's probably B.
When x is 1, y is 1.5 When x is 2, y is 2.6 When x is 3, y is 2.2 When x is 4, y is 3 When x is 5, y is 2.9 When x is 6, y is 4.6 When x is 7, y is 4.2 When x is 8, y is 5 The numbers aren't adding up :/ Is what I stated above, correct? A is clearly wrong: ex. y=-2x +1 1.5...
Yes, I was also thinking that it seemed too easy.
Total # of students = 57 Band students = 25 Band or Choir or Both students = 48 Choir and Math students = 9 So from what you stated in about the Venn diagram, it shows that only 7 students take exactly 2 courses from Mr. Green (Math and Band). So wouldn't it simply be 7 st...
2 right angled triangles = 1 equilateral triangle. You can pretty much split it down the middle and you'll see the 2 triangles from. The formula for a right angle triangle is: (b x h)/2 = area If we were solving for 1/2 the triangle we know that the base is 5 cm, the heigh...
