Answer:
The ladder will reach 4.6 ft up the tree.
Step-by-step explanation:
When we draw out our triangle, we should see that we are given the horizontal leg and are trying to find the vertical leg. We use tan∅ to help solve:
tan53° = x/3.5
3.5tan53° = x
x = 4.64466
48/15 = 3.2 round to nearest whole number (3)
48-3 = 45 men
The answer is 7
Step by step 5 apples and 2 oranges
Answer:
t = 1.41 seconds
Step-by-step explanation:
We know the height at which the coconut is, which is 64 ft, now assuming that we are on the ground, we know that gravity is equal to 32.1742 ft / s².
Gravity is an acceleration, we have that the acceleration is equal to:
a = v / t
but the speed v = d / t, replacing we have:
a = (d / t) / t
That is to say
a = d / t²
Now, solved for you we have:
t = (d / a) ^ (1/2)
Replacing the values, we are left with:
t = (64 / 32.17) ^ (1/2)
t = 1.41 seconds
therefore, the person has 1.41 seconds to escape.
