First, find 300% of 25.
Percentages are parts of 100, so divide 300 by 100.
300 / 100 = 3.
So multiply that to 25.
3 * 25 = 75
Add it to 25:
75 + 25 = $100
1/5 x 100 = 20%
Answer: 20%
Answer:
Its 102.5
Step-by-step explanation:
Multiply one of them by -1 so one of the -2y is positive
-1(-7x-2y=-13)=7x+2y=13
Then add the two equations
7x+2y=13
+ x-2y=11
========
8x=24 - the 2y and -2y cancel out. Now solve for x
x=3 Now plug the x back into one of the equations
3-2y=11 Now solve for y
-2y=11-3
-2y=8
y=-4
So x=3 and y=-4
Hope this helps!
Answer:
Ella’s procedure and conclusion are incorrect.
Step-by-step explanation:
The sum of the squares of the short sides can be compared to the square of the long side to see if the triangle is acute, right, or obtuse. The appropriate conclusions are ...
- a² +b² > c² -- acute triangle
- a² +b² = c² -- right triangle
- a² +b² < c² -- obtuse triangle
For Ella's side lengths, the appropriate "work" is ...
10² +11² ?? 15²
100 +121 < 225
The triangle is obtuse.

Ella used an incorrect comparison and came to the wrong conclusion. Both her procedure and conclusion are incorrect.
