The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5.
Let take some example
Let the sides of triangle are 10, 6 and 8 . If it is dilated with with respect to origin by a scale factor of 0.5 then we multiply the sides by scale factor. so the sides becomes 5, 3 and 4. The perimeter 10+6+8 = 24 becomes 5+3+4 =12 after dilation by a scale factor 0.5.
The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5. then we multiply the perimeter by scale factor 0.5.
So 30 * 0.5 = 15 units.
15 units is the perimeter of the resulting triangle.
Answer:
$127.68
Step-by-step explanation:
Rate= 6.4%
Principal= $120
Time = 1 year
Required
The final amount A
Step two
A=P(1+rt)
substitute
A=120(1+0.064*1)
A=120(1.064)
A=120*1.064
A=$127.68
Hence the final amount is $127.68
a) Let f be the cost of each ticket. We know that 2 tickets cost a total of $24.95, so therefore we have this equation:
2f = 24.95
b) Solve this equation by dividing both sides by 2:
f = 12.475
This value isn't possible with money so to make it realistic, we'll round to the nearest cent:
f = $12.48
c) We're ordering one more ticket, so we'll just add f to our total cost:
64.50 + f
= 64.50 + 12.48
= $76.98
