Answer:
c. 47.7 m
Step-by-step explanation:
If you draw a right triangle to represent the problem, the catheti are the vertical distance from the bird's eyes to the field mouse and the separation from the field mouse to the base of the tree. The 50° of depression is measured from the horizontal in clockwise, the angle that summed with the 50° of the depression can be called α. Then:
α+50=90
α=90-50=40°
The trigonometric function than relates te two catheti with the angle α is:
tan(α)=opposite/adjacent
tan40=40/x
x=40/tan40=40/0.8390=47.7m
Answer:
y = 1/2x + 5
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
When 2 lines are parallel, they have the same slope.
Step 1: Define variables
Random point (2, 6)
<em>m</em> = 1/2
y = 1/2x + b
Step 2: Find <em>b</em>
6 = 1/2(2) + b
6 = 1 + b
5 = b
Step 3: Rewrite parallel linear equation
y = 1/2x + 5
Answer:
The answer is 20s+10h=500
Step-by-step explanation:
The reason is because 20 times 20=400 and then 10 times 10= 100 then you add those together and get $500
You distribute the problem as shown;
2(x+5) 2 times x+2 times 5=2x+10
The answer is 2x+10!
Answer: x=20/3=6.67
Step-by-step explanation:
To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.
-----------------------------------------------------------------------------
Given
x:10=9:6
Cross Multiply
9·x=6·10
9x=60
Divide 9 on both sides
9x/9=60/9
x=20/3=6.67
Hope this helps!! :)
