The angle of depression from a descending airplane to the control tower below is 60∘.
If the plane is 35,000 feet above the ground, approximately what is the plane's horizontal distance from the control tower?
A) 70,000
B) 20,207
C) 60,622
D) 24,749
Answer:
The answer is B) 20,207 ft
Step-by-step explanation:
The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y. Write any fractions in the simplest form. When y=20 , x=12.
Given:
y is proportional to x.
y=20 and x=12.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting y=20 and x=12, we get
[tex]20=k(12)[/tex]
[tex]\dfrac{20}{12}=k[/tex]
[tex]\dfrac{5}{3}=k[/tex]
Putting [tex]k=\dfrac{5}{3}[/tex] in (i), we get
[tex]y=\dfrac{5}{3}x[/tex]
Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{3}[/tex] and the equation for the proportional relationship is [tex]y=\dfrac{5}{3}x[/tex].

Please help me with this sheet asap!!!!b
Step-by-step explanation:
1)
SA= 2 (Length x Breadth + breadth x height + Length x height)
SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2
2)
2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2
3)
2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2
4)
SA=
[tex]A=2πrh+2π {r}^{2}
[tex]A=2πrh+2π {r}^{2} [/tex]
= 2π 6*5+2π6*6= 188.495+226.194
SA= 414.689 cm^2
5)
2π7*4+2π*4*4=
SA=276.46 cm^2
6)
2π6*4+2π*4*4=
SA= 251.33 cm^2
7)
(3*4)/2=6
(3*4)/2=6
(3*8)=24
4*8=32
8*5=40
SA =6+6+24+32+40=108 cm^2
8)
(6*8)/2=24
(6*8)/2=24
6*12=72
8*12=96
10*12=120
SA= 24+24+72+96+120= 336 cm^2
9)
(5*12)/2=30
(5*12)/2=30
5*8=40
12*8=96
13*8=104
SA= 30+30+40+96+104= 300 cm^2

In a group of 20 students, 7 study both Art and Biology.
5 study Biology but not Art.
8 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
Step-by-step explanation:
A + B = 7
(Not A) + B = 5
(Not A) + (Not B) = 8
(Not A) = ((Not A) + B) + ((Not A) + (Not B) = 13
A = 20 - (Not A) = 7
Prob (A + B) given (A)
Prob (A+B) || A = (7/20) / (7/20)
Prob (A + B) || A = 1

help!! what’s the equation for the green line.
Answer:
y=x-3
Step-by-step explanation:
slope intercept form equation is y=mx+b
b is the y intercept(where it crosses on the y-axis)
b=-3
m is the slope
slope is rise over run (start from -3)
slope is 3 over 3 (count up 3 from -3, count right 3)
3 over 3 is 1
1x is the same as x
final answer y=x-3

4 boys have a mean height of 162cm.Another boy with a height of 165cm joins them.What is the new mean height?
Answer: 162.6cm
Step-by-step explanation:
4 boys have a mean height of 162cm. Their total height will be the average multiplied by the number of boys which will be:
= 162 × 4
= 648cm
A new boy with height of 165cm joined. This means that we now have 5 boys and their total height will be:
= 648cm + 165cm
= 813cm
The new mean height will be:
= Total height / Number of boys
= 813 / 5
= 162.6cm
