The crane is 139.8cm tall.
<h3>what is angle of elevation?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Using Trigonometry
tan 30 = h/y
1/√3 = h/y
y= h√3
and, tan 25= h/y+62
0.96= h/(h√3 +62)
h= 0..96 (h√3 +62)
h= 0.96*h*1.732+0.96*62
h=0.796h +28.52
0.2404h= 28.52
h= 139.8 cm
Hence, whooping crane is 139.8 cm.

Y intercept is (0,-4)
So the Answer is
Y=3x-4
Answer:
The machine can make 24 bottles of soda per minute
Step-by-step explanation:
Looking at the graph of the relationship, we can see that the number of bottles per minute simply represent the slope of the line
Thus, by calculating the slope using the given points, we can have the number of bottles per minute
We have the formula as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (4,96)
(x2,y2) = (6,144)
m = (144-96)/(6-4) = 48/2 = 24
Answer:
6.71
You use pythagoras so you do:
6² + 3² = 45
square root 45 =6.71
Answer:
Step-by-step explanation:
add all of them up, Julie, 6 + 12 + 3 + 4 = 25
there are 25 total students. now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
