Hi I did my working on paper. You can see it in the photo.
The answer is 10 because if you round It Off it will be 5 + 10 equal 15 Sultan is the answer to your question
Assuming your first equation is y = 5x+9, the equations describe lines that are coincident.
_____
Multiplying the second equation by -1, it becomes y = 5x+9, the same as the first equation.
Answer:
11779 ft
Step-by-step explanation:
We are given that
![\theta=23^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D23%5E%7B%5Ccirc%7D)
Distance between tower and plane,d=5000 ft
We have to find the distance between the plane and bird.
Let x be the distance between bird and plane
We know that
![tan\theta=\frac{perpendicular\;side}{Base}](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cfrac%7Bperpendicular%5C%3Bside%7D%7BBase%7D)
Using the formula
![tan23=\frac{5000}{x}](https://tex.z-dn.net/?f=tan23%3D%5Cfrac%7B5000%7D%7Bx%7D)
![x=\frac{5000}{tan23}=11779.3 \approx 11779ft](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5000%7D%7Btan23%7D%3D11779.3%20%5Capprox%2011779ft)
Hence, the distance between the plane and bird=11779 ft
Answer:
25
Step-by-step explanation:
2 out of 12 means also 1 out of 6.
so, a ratio of 1:6 or a factor of 1/6.
150 × 1/6 = 150 / 6 = 25
so, we expect that out of the 150 sold cars 25 have been red.
