Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
The answer is B.
If you find a common denominator, the process becomes much easier. I hope this was helpful.
Answer:
45 or positive 45
Step-by-step explanation:
The tree grows 6cm per year and we need to find out how long it will take to grow 1 meter. We know that 1 meter is equal to 100 centimeters. So:
6x = 100
x = 16.67
It will take 16.67 years (or one and two-thirds of a year) for the tree to reach 1 meter.
10 feet.
Equation: a = v1/3 = 1000 1/3 = 10ft.
