Answer:
Step-by-step explanation:
GIVEN: A square with base 
, a circle that perfectly fits inside square.
TO FIND: Approximate area of circle.
SOLUTION:
Consider the figure attached.
let the radius of circle be 
radius of circle 
Area of circle 
Hence the area of circle that perfectly fits inside the square is
There’s no picture but look for the one that is 0,-1
As a decimal 3/5 = 0.6
Multiply the height by 0.6:
1st bounce = 125 x 0.6 = 75
2nd bounce = 75 x 0.6 = 45
3rd bounce = 45 x 0.6 = 27
The answer is 27cm
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)
little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
Answer:
C
Step-by-step explanation:
Given the 2 equations
x + y = 4 → (1)
x - y = 6 → (2)
Add the 2 equations term by term to eliminate y, that is
2x = 10 ( divide both sides by 2 )
x = 5
Substitute x = 5 into either of the 2 equations and evaluate for y
Substituting into (1)
5 + y = 4 ( subtract 5 from both sides )
y = - 1
solution is (5, - 1 ) → C
