Answer:
4 3/4 & 19/4
Step-by-step explanation:
Note that for the point, the whole number to the left is 4, and the whole number to the right is 5. This means that the number is 4 (& some).
Next, note that there are 2 lines in between the numbers This means that the amount in between is by 1/4s.
This means that the denominator would have to be a 4 (which means only C & D work).
Now, note that both says 4 3/4, and so change it to an improper fraction
4 = 16/4
16/4 + 3/4 = 19/4
D) is your answer choice.

Will you give me the numbers so I can give you the answer?
Step-by-step explanation:
Answer:
(2,1)
Step-by-step explanation:
So the first thing you want to do is substitute. You want to plug in the equation for y in for the y value above.
So you would do 3x+4(x-1)=10. As you can see we took the bottom equation and put it in for the top equation. We did this so we only have x s and no y s.
Now you would solve. You would distribute first. You would get 3x+4x-4=10. Now combine like terms. 3+4 is 7 so you would get 7x-4=10.The next thing you want to do is get the 7x by itself so move the 4.You would get 7x=14. Now divided both sides by 7 because you want to get the x by itself.
You would get x=2. Now for the y value just plug it in for an equation above. The easier one would be y=x-1. y=(2)-1 will equal 1. You write your final answer in (x,y) style. Your final answer will then be (2,1)

Answer:
The ladder has to be 65 feet long to the nearest foot.
Step-by-step explanation:
The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.
Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.
Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.
Therefore, using trigonometry we can write,
![\sin 75.5 ^{\circ} = \frac{\textrm {The height of the chimney from the ground}}{\textrm {Length of the ladder}} = \frac{63}{\textrm {Length of the ladder}}](https://tex.z-dn.net/?f=%5Csin%2075.5%20%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7B%5Ctextrm%20%7BThe%20height%20of%20the%20chimney%20from%20the%20ground%7D%7D%7B%5Ctextrm%20%7BLength%20of%20the%20ladder%7D%7D%20%3D%20%5Cfrac%7B63%7D%7B%5Ctextrm%20%7BLength%20of%20the%20ladder%7D%7D)
⇒ The length of the ladder = 65 feet.
Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)
