Answer:
B. 32
Step-by-step explanation:
25% is 1/4 of 100%, so you multiply 8 by 4.
Answer: B. An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles. dd
Step-by-step explanation:
An isosceles is a triangle that has two sides of equal length.
The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.
Thus, it also has two equal angles and one non equal angle. Thus, it does not have all congruent angles.
- The order of rotational symmetry of a figure is the number of times we rotate up to 360° the figure such that it looks exactly the same as the original figure.
When we rotate the isosceles triangle up to 360° , only 1 time it looks exactly same as in the beginning because at each rotation the order of angles changes.
Therefore, An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.
Answer:
D
Step-by-step explanation:
Answer:
none of the options
Step-by-step explanation:
4x − 5y = 2 , 10x − 21y = 10
---------
the first equation is same in all answer choices, let's check which is equivalent to second, the easy way is to consider x/y ratio which is 10/ -21
4x − 5y = 2 , 3x − y = 4
4x − 5y = 2 , 24x − 47y = 22
4x − 5y = 2 , 10x + 3y = 15
4x − 5y = 2 , 14x + 26y = 12
Well the ratio is 16:20 which it 16/20. We can simplify that to 4/5. Therefore the ratio from pink stripes to green stripes will be 4:5
