Answer:
3x-6y
Step-by-step explanation:
Because he divided his cake into 6 equal pieces, we can represent the eaten and remaining amounts with fractions.
Remember that a fraction is the ratio of number of pieces over the total pieces.
So, we need to figure out how much cake needs to be subtracted.
We know his sister ate 1/6 of the cake and he ate 3/6 of the cake. We can add these fractions together because they have common denominators.
3/6+1/6=4/6
So, we need to subtract 4/6 from the whole:
6/6-4/6=2/6, so 2 slices out of the 6 remain.
You are correct. The area of a square with side lengths of 1/3 yard is 1/9 yd^2.
To get this answer, you muse use the formula for finding the area of a square, which is s^2, where s represents the value of a side length.
The value of the side length in this case is 1/3 yard, so we should substitute that value in for s.
When we do this, we get the following:
A = (1/3 yd)^2 = 1/9 yard^2
Therefore, your answer is 1/9 yd^2.
Hope this helps!
Answer: not a triangle
Step-by-step explanation:
If this were to be a triangle, the shorter sides would be 11 and 4 and the longest side would be 16.
First, we should determine if it is a triangle.
- Sum of shorter sides = 15
- This is less than the longest side, 16, so therefore, it is <u>not a triangle</u>.
Answer:
Step-by-step explanation:
No, it is an ancient problem which has been proved to be impossible (in 1837), at least not for an arbitray angle.
However, we can trisect certain angles, such as 90 degrees, but rather than trisection, we are just constructing 30 degree angles.
