Answer:
936m
Step-by-step explanation:
What we have here is a rght triangle, where one leg is the hight between the nest and the bird (400 - 20 =380) and the other is the distance between the bird and the nest linearly from the ground (name it X). The hypotenuse is the distance the bird will fly ( name it H).
Is not clear if we need to find X or H so we will find both.
First, to find H we use the trigonometric formula:
Sin(24) = leg opposed / hypotenuse
Sin(24) is 0.406 aprox
So,
0.406 = 380/h -> h = 380/0.406 = 936 (aprox)
Then we find X, the adjacent leg to 24° using the formula:
Cos(24) = X / hypotenuse
Cos(24) is approximately 0.91
So:
0.91 = X / 936 -> X=0.91*936= 852 (aprox)
So, the distance ir 936 ir 852, depending on what you need. The statement is not very clear (however I guess it is 936 as is the distance the bird Weill fly)
Answer:
15 & 7
Step-by-step explanation:
f - s = 8
f = 8 + s
Twice the first number plus three times the second number is 51:
2f + 3s = 51
Substitute:
2(8 + s) + 3s = 51
16 + 2s + 3s = 51
16 + 5s = 51
5s = 51 - 16
5s = 35
s = 7, the second number
Find f:
f = 8 + 7 = 15, the first number
f - s = 8
15 - 7 = 8
8 = 8
The probability for a boy is 8/12 and the girls is 4/12 so that's a 4/12 diffrence
