Alladin's Amusement Park has a popular roller coaster ride. There are 2 trains. Each train has 7 cars. Each car holds 16 people. In one hour, each train makes 10 runs without no empty seats. How many people can ride the roller coaster in one hour?
Answers
Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains [tex]\times[/tex] Number of cars in each train = [tex]7\times 2[/tex] = 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car [tex]\times[/tex] Number of cars = 16 [tex]\times[/tex] 14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224 [tex]\times[/tex] 10 = 2240

Esme wants to make a rectangular pen for her chickens. She has 140 feet of fencing available to use. She wants to put the pen against the side of her barn. In other words, one side of the pen does not need fencing. Determine the maximum possible area she can create.
Answers
Answer:
2450 square feet
Step-by-step explanation:
We can first draw a rectangle with one side labeled Esme's wall. Then on one of the sides perpendicular to the "wall", we can assign a variable "x" for its length. The opposite of that side must have the same length "x". The unlabeled side that is opposite to the wall must have a length of "140-2x" because only 140 feet of fencing is available.
The area of a rectangle is equal to its length times its width, so the area of Esme's pen must equal "x" times "140-2x". If we graph this on a graphing calculator, we get a concave-down parabola. Since the input (x-axis) of this graph is the length of "x" and the output (y-axis) is the area Esme's pen, the highest y-value (which is the y-value of the vertex) will be the highest area that she can create. The vertex of this graph is (35, 2450), so the maximum area is 2450 square feet.
The non-calculator method involves expanding the expression "x(140-2x)" and finding the vertex through converting the expression to vertex form. (but... I'm too lazy to write out the vertex form for this expression so sorry no work here)

How do you do this geometry
Answers
Answer:
y = 62
z = 35
Step-by-step explanation:
Basically, you know one of the angles, that is 62. And since y is the same angle as 62 that would also be 62. And since the straight line is 180, just subtract 180 - 62, and that equals 118. So, then I just tried to find numbers that when multiplied by 6, and then subtracted by 92, equal 118. Honestly, z was just a guessing game for me. But I do know that I got the right answer, i just didn't figure it out the right way lol.
Good luck!
Answer:
y = 118°
z = 35
Step-by-step explanation:
All 8 of the angles formed by these three lines are only two different measures. They are all either 62° or
(180°-62°) 118°.
Also, any two of the angles are either the same or they add up to 180°.
The angle marked y° and the 62° angle are called "consecutive" angles or "same-side interior angles. They add up to 180°
y + 62° = 180°
y = 118°
The angle marked y° and the angle marked (6z - 92)° are called "vertical angles" and they are equal.
6z - 92 = 118°
add 92.
6z = 210°
Divide by 6.
z = 35

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]
So, by exterior angle property of a triangle, we have:
[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\
(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\
(10x - 1)\degree = (3x +17+2x +12)\degree\\\\
(10x - 1)\degree = (5x +29)\degree\\\\
(10x - 1)= (5x +29)\\\\
10x - 5x = 29 + 1\\\\
5x = 30\\\\
x = \frac{30}{5}\\\\
x = 6\\\\
\because m\angle QRS = (10x - 1)\degree \\\\
\therefore m\angle QRS = (10\times 6- 1)\degree \\\\
\therefore m\angle QRS = (60- 1)\degree \\\\
