Answer:
see explanation
Step-by-step explanation:
Since figure B is smaller than Figure A then Figure B is a reduction.
To find the scale factor, calculate the ratio of corresponding sides, image to original.
Using the base lines of both triangles, then
scale factor k =
= 
Answer:
The range is 35.465 to 35.535
Step-by-step explanation:
Subtract 0.035 from 35.5 then add 0.035 to 35.5.
Answer:
Base of the original triangle is 12 cm.
Step-by-step explanation:
Let base of triangle be x
two equal legs of triangles by y
therefore perimeter of triangle
x+y+y = 50 or x+2y =50
according to the question
if base is x+3 and leg is y-4
then both are equal
that is x+3 = y-4
y-x = 7 or y =x+7
x+2y =50
x+2(x+7) = 50
x+2x +14 =50
3x +14 =50
3x = 50 -14
3x = 36
x = 12
therefore base of the original triangle is 12 cm
Answer:
equation: 4x+6=9
x=0.75
Step-by-step explanation:
4x+6=9
subtract 6 from both sides
4x+6-6=9-6
4x=3
divide by 4 on both sides
4x÷4=3÷4
x=0.75
