Answer:
The figure will change by a factor of 2.25.
Step-by-step explanation:
When the lengths (1-dimensional) change by a factor 1.5 (the definition of <em>dilating </em>a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.
Answer:
Step-by-step explanation:
the longest length is always the hypotenuse
Use Pythagorean theorem
a^2+b^2=c^2
5^2+10^2=c^2
c=11.18
Note: if c=13 than it is a right triangle
since 11.18 not=13
not right triangle

Answer:
2 minutes, 40 seconds
Step-by-step explanation:
set up a proportion and cross-multiply:
4/3 = x/2
3x = 8
x = 2 2/3 which is 2 minutes, 40 seconds
