Answer:
To determine the exponential growth of Michelle's tree at 12 years, taking into account that it measures 7 feet and grows 14% annually, the following calculation must be performed:
X = 7 x (1 + 0.14) 12
X = 33.7
Thus, in 12 years, the height of Michelle's tree will be 33.7 feet. In turn, the tree of Tara will measure 58 feet at the same time.
The first time Michelle's tree surpasses Tara's will be at age 20, when Michelle's tree will measure 96.2 feet (X = 7 x (1 + 0.14) 20), while Tara's tree will measure 90 feet.
Answer:
A
Step-by-step explanation:
What we need to know simply is the time taken for both trips. We know the car spent 6 hours on the first leg, that is settled.
What we do not know is the time spent on the second leg. To get the time spent on the second leg of the journey, we only need to get the total distance divided by the speed.
We can get the distance using the first part of the question. The time is 6 hours and the speed is x miles per hour, the total distance is this 6x miles.
Now we need to know the time spent on the second leg of the journey. We know that the distance is the same. Hence the time spent is 6x/y where y is the speed for the second leg and 6x is the length of each leg
Now the total time spent is thus (6x/y +6) hours. We need to however convert this to minutes. We do this by multiplying by 60
(6x/y + 6) * 60

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
w = 180° - (90 + 31) °= 180° - 121° = 59°
y = 59° ( vertical angle to w )
w and v are adjacent angles, thus
w + v = 180°
59° + v = 180° ( subtract 59° from both sides )
v = 121°
x = 121° ( vertical angle to v )
Thus
v = 121°, w = 59°, x = 121°, y = 59°
