Answer:
5/12
Step-by-step explanation:
Jill 1/12
Mark 2/12
Lou 1/12
Sam 3/12
add them together
7/12
12-7=5
5/12
Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
Answer:
x=7
Step-by-step explanation:
- 4(x-2) = 2x+3(x-5)
- 4x-8 = 2x+3x-15
- 4x-8 = 5x -15
- -x = -7
- x = 7
For the first question, we can extend all of the lines on the trapezoid, and triple the distance from B on the line, so we can use the fact that B is (2, 2), A is (0, 0), C is (4, 2), and D is (6, 0) to get that the new coordinates are A (-4, -4), B (2, 2), C (8, 2), and D (14, -4).
For the second question, notice that we are changing the size on the same line, and every side length is tripled by 3. If every side length is tripled by 3, then the perimeter of the new image is triple the perimeter of the original.
