Answer:
42.9 ft
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.
tan(47°) = height/(40 ft)
height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)
height ≈ 42.9 ft
The tree is about 42.9 feet tall.
Answer:
2/3 magazines per hour
Step-by-step explanation:
Olivia writes 2 new sheets of magazines in 3 hours.
The rate per hour at with she writes the sheets of magazines is the number of sheets divided by the amount of time taken to write the sheets.
Hence, the rate per hour is:
R = 2 / 3 = 2/3 magazines per hour
The rate per hour at with she writes the sheets of magazines is 2/3 magazines per hour.
30.8
5.6 times 22 divided by 2 divided by 2
Answer:
(x, y) ==> (-4, -3)
Step-by-step explanation:
-2(3x + y = -15) ==> -6x - 2y = 30
3x + 2y = -18
-6x - 2y = 30
3x + 2y = -18
-3x = 12
/-3 /-3
x = -4
Now, we solve for y:
-6x - 2y = 30
-6(-4) - 2y = 30
24 - 2y = 30
-24 -24
-2y = 6
/-2 /-3
y = -3
(x, y) ==> (-4, -3)
Hope this helps!
