Answer:
70%
Step-by-step explanation:
To find the decrease:
original/current
450/315 = .7
Now multiply .7 by 100 to get a percent
.7 * 100 - 70%
450 * .7 = 315
70% is the answer!
Answer:
(12,0), (3, -1) (0,-4/3)
Step-by-step explanation:
To do this problem, you have to plug in the x and y values. For example, the first one would be 12-9(0)=12, and so on.
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
Answer:
169.70563
Step-by-step explanation:
If it's pythagorean theoram then i used 
a and b would be 120.
doing all that would get you the answer.
if this helped...great.
To make calculation easier, we first multiply
1.35 × 100 = 135
then we need to find how many groups of 5 are there in 135.
to do so, we simply take
135 ÷ 5 = 27
therefore, the answer is <u>27.</u>
