Answer:
10.4%
Step-by-step explanation:
The original price = $2.40
Price after drop = $2.15
The drop = $2.40 - $2.15 = $0.25
Percentage decrease =
× 100
i.e Percentage decrease =
× 100 = 10.41666667%
Or 10.4% (Rounded up to nearest tenth of a percent).
All of these angles can be compared to each other.
There are:
- Alternate interior angles
-- Angles that share one line and two parallel lines and are less than 90 degrees (angles 10, 12). These angles are equal to each other.
- Alternate exterior angles
-- Angles that share one line and two parallel lines and are more than 90 degrees (angles 1,5) These angles are equal to each other.
- Vertical Angle
-- Angles that share a point and are opposite of that point (angles 2,3) These angles are equal to each other.
-Supplementary angles
-- Angles that are on the same side of one line and share the side of another (angles 9,10). These angles are always equal to 180 degrees.
Using this we know:
a. m of angle 5 = to the m of angle 3 = 102
m of angle 5 = 102 degrees
Answer:
No
Step-by-step explanation:
All the numbers have to be multiplied by the same amount for it to be proportional
A proportional amount to 4:2:1:5 would be 12:6:3:15
They have all been multiplied by the same number 3
