A contraction would make the image smaller.
A negative number reflects the image and changes the size based on the number.
To make an image smaller the factor needs to be less than 1
so -0.5 and 0.5 would make the image smaller since 0.5 is less than 1.
The area of a triangle in terms of height and base is A = 1/2*base*height
Suppose base = 6 cm and height = 12 cm. Then, A = 1/2*6*12 = 36 cm2.
If the base and height are scales by a factor of 5, b= 30 cm and h = 60 cm. Then, A = 1/2*30*60 = 900 cm2.
Thus the area of the resulting triangle is scaled by a factor of 25, which is 900 cm2.
Answer:
E $10240.00
Step-by-step explanation:
The total amount of money is x.
3/8 × x = 3840
Multiply both sides by the reciprocal of 3/8 which is 8/3.
x = 3840 × 8/3
x = 10240
Answer: E $10240.00
