Answer:
the answer for apex is shift
Step-by-step explanation:
Well, you get the volume by multiplying the height, the width, and the length. So just work on it backwards.
2,830.5 divided by (9 times 18.5).
9 times 18.5 is 166.5. So that leaves us with 2,830.5 divided by 166.5, which is 17.
So, the answer is 17.

Using proportions, it is found that it will take him 22.5 hours to walk the 45 dogs.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
He walks 3 dogs in 1 hour and 30 minutes, we means that the time in hours it takes for him to walk a dog is:
t = 1.5/3 = 0.5 hours.
Hence the time it will take him to walk 45 dogs is given by:
45 x 0.5 = 22.5 hours.

<em>The area of QRS is </em><em>238.7</em><em> sq units.</em>
<u>Solution-</u>
According to properties of supplementary angles,
![m\angle R+124=180\\\\m\angle Q+132=180](https://tex.z-dn.net/?f=m%5Cangle%20R%2B124%3D180%5C%5C%5C%5Cm%5Cangle%20Q%2B132%3D180)
So,
![\Rightarrow m\angle R=180-124=56,\ m\angle Q=180-132=48](https://tex.z-dn.net/?f=%5CRightarrow%20m%5Cangle%20R%3D180-124%3D56%2C%5C%20m%5Cangle%20Q%3D180-132%3D48)
As the sum of measurement of all the angles in a triangle is 180, so
![\Rightarrow m\angle S+m\angle R+m\angle Q=180](https://tex.z-dn.net/?f=%5CRightarrow%20m%5Cangle%20S%2Bm%5Cangle%20R%2Bm%5Cangle%20Q%3D180)
![\Rightarrow m\angle S=180-m\angle R-m\angle Q](https://tex.z-dn.net/?f=%5CRightarrow%20m%5Cangle%20S%3D180-m%5Cangle%20R-m%5Cangle%20Q)
![\Rightarrow m\angle S=180-56-48=76](https://tex.z-dn.net/?f=%5CRightarrow%20m%5Cangle%20S%3D180-56-48%3D76)
Then the area of the triangle will be,
![\text{Area}=\dfrac{1}{2}qr\sin S](https://tex.z-dn.net/?f=%5Ctext%7BArea%7D%3D%5Cdfrac%7B1%7D%7B2%7Dqr%5Csin%20S)
![=\dfrac{1}{2}\times 21\times 23.43\times \sin 76](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%2021%5Ctimes%2023.43%5Ctimes%20%5Csin%2076)
![=238.7\text{sq.units}](https://tex.z-dn.net/?f=%3D238.7%5Ctext%7Bsq.units%7D)
