ABC is a right triangle where AC and AB are the legs, and CB is the hypotenuse. Using Pythagorean theorem:
CB² = AB² + AC²
CB² = 16² + 12²
CB² = 256 + 144
CB² = 400
CB = √400
CB = 20 in
In triangle BCR, CB is the base and SR is its altitude
The area of a triangle is:
![A\text{ =}\frac{base\cdot altitude}{2}](https://tex.z-dn.net/?f=A%5Ctext%7B%20%3D%7D%5Cfrac%7Bbase%5Ccdot%20altitude%7D%7B2%7D)
Then, the area of triangle BCR is:
C=1/2n+8 would be the answer
Answer: a=225 adult, s=200 student
Explanation: We need a system of equations to find how many of each ticket Marc sold and we can use 4s+5a=1925 and s+a=425.
If we isolate a, we will have a=425-s
If we plug this into the first equation, we will get 4s+2125-5s=1925
Solving for s gives us s=200.
To find a, we can do 425-200 to find that a=225.
I believe your answer is 4 4/9 as a mixed fraction but it can also be 40/9. Hope this helps :)
The speed of the plane will be 875km/h and the speed of the wind will be 125km/h.
<h3>How to calculate the speed?</h3>
It should be noted that the speed is calculated as:
= Distance/Time
Based on the information, the DC10 airplane travels 3000 km with a tailwind in 3 hr. It travels 3000 km with a headwind in 4 hr.
Therefore, (v + w) = 3000/3
v + w = 1000 .... I
(v - w) = 3000/4
v - w = 750 .... ii
We'll then add both equations together. Therefore, the speed of the plane will be 875km/h and the speed of the wind will be 125km/h.
