Answer:
h ≈ 66.4 ft
Step-by-step explanation:
The situation can be modelled by a right triangle with h representing the height of the tree.
Using the tangent ratio in the right triangle
tan39° = = ( multiply both sides by 82 )
82 × tan39° = h , then
h ≈ 66.4 ft ( to the nearest tenth )
Answer: C
Step-by-step explanation:
Ur fraction will be 18/20 so just multiply the numerator and denominator by 5 Now we can see that our fraction is 90/100, which means that 18/20 as a percentage is 90%.
The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
(4/9)/(2/3)/(5/6)
