Step-by-step explanation:
This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid! Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.
IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid
The volume of a square pyramide is .....
V = side² × (height / 3)
The volume of a rectangular pyramide is .....
V = base area × (height / 3)
= length × width × (height / 3)
= 12 × 6 × 10 / 3 cm³ BUT REMEMBER we want only HALF of the
= [12 × 3 × 10] divide by 2 cm³ Rectangular pyamid
Volume of the image shown in the diagram is ....
= 360 / 2 cm³
= 180 cm³ <----------------- Final Answer
Carlene has 2 8/12 yards of ribbon left over.
First) You write the problem.Then find a common denominator for both fractions (common denominator is 12 since 6 x 2 = 12 and 2 x 6= 12)
Second)You write equivalent fractions that end with a denominator of 12. (8 2/12 and 5 6/12)
Third)You need to rename the mixed numbers since you cannot take away 6/12 from 2/12. ( Rename the numbers as 7 14/12 and keep the 5 6/12 the same)
Lastly, you subtract the whole numbers, and the numerators and get your answer of 2 8/12.
Hope this helps!
I think it would be on a 100 point exam
Step-by-step explanation:
Given
g(x) = - 2x² + 3x
g(3) = - 2 * 3² + 3 *3
= -2 * 9 + 9
= -18 + 9
= -9
