Answer:
3 pickles per burger lol
1:3
Step-by-step explanation:
Answer:
3:9
1:3
because we know that it is 3:9 So we have to simplify it and then 3 divided by 3 equals 1 so 9 divided by 3 is 3

4. A theater has a seating capacity of 900 and charges $2.50 for children, $4 for students, and $5.50 for adults. At a certain screening with full attendance, there were half as many adults as children and students combined. The total money brought in was $3825. How many children, students, and adults attended the show?
Answer:
We have 3 variables to solve for. We will start by writing two equations in three variables but, with the given information, will eventually have those equations written in 2 variables. The strategy is to set up equations from the given information and solve the equations simultaneously. Let's assign variables...
c= #children total
s= #students total
a= #adults total
c+s+a=900.............Eq1, total attendance, given
4c+6s+8a=5600....Eq2, total receipts, given
a=(1/2)(c+s)
=(1/2)c+(1/2)s.....Eq3, #adults total, given
Let's substitute Eq3 into each Eqs1,2 to get two equations in two variables...
c+s+(½c+½s)=900.........Eq1, substitute for"s"
1.5c+1.5s=900.......combine like terms
3c+3s=1800.....Eq4, multiple equation
by 2 to eliminate fraction
4c+6s+8(½c+½s)=5600...Eq2, substitute for "s"
4c+6s+(4c+4s)=5600...distribute 8
8c+10s=5600...Eq5, combine like terms
Let's solve newly arrived at Eq4,5 simultaneuously...
3c+3s=1800......Eq4
8c+10s=5600......Eq5
-24c-24s=-14400...Eq4 multiplied by (-8)
24c+30s=16800...Eq5 multiplied by 3
------------------------
6s=2400.....add all terms vertically
∴ s=400.......divide both sides by 6
Substitute value back into Eq4, solve for "c"...
3c+3s=1800...Eq4
3c+3(400)=1800...substitute for"s"
3c+1200=1800
3c=600.....subtract 1200, both sides
∴ c=200....divide both sides by 3
Substitute values back into Eq3, solve for "a"...
a=(1/2)(c+s).............Eq3
=(1/2)(200+400)...substitute for "c,s"
=(1/2)(600)
∴ a=300.....................simplify
We now have our three variables solved. Let's substitute those values back into original Eqs1,2 to check against the problem requirements...
c+s+a=900.......Eq1
200+400+300=900....substitute for "c,s,a"
900=900......true, √check
4c+6s+8a=5600.....Eq2
4(200)+6(400)+8(300)=5600...substitute for
"c,s,a"
800+2400+2400=5600...simplify
5600=5600......true, √check
So our calculated values are correct. Always check your solutions and work!
In summary, we have...
200 children, 400 students, and 300 adults in attendance at the theater for the screening.
Step-by-step explanation:
There were total 150 childrens, 450 students and 300 adults.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is a theater that has a seating capacity of 900 and charges $2.50 for children, $4 for students, and $5.50 for adults. At a certain screening with full attendance, there were half as many adults as children and students combined. The total money brought in was $3825.
Assume that there were [x] childrens, [y] students and [z] adults. Then, we can write the equations as -
x + y + (1/2)(x + y) = 900
2.5x + 4y + (5.5)(1/2)(x + y) = 3825
Plot the graph. We will get x = 150 and y = 450.
Then -
z = (1/2)(150 + 450) = (1/2)(600) = 300
Therefore, there were total 150 childrens, 450 students and 300 adults.

Does the relationship {(1,1), (2,1),(3,2), (4,3), (5,5), (6,8), (7,13)} represent a function?
Yes
Answer:
Yes.
Step-by-step explanation:
A function is a set of relations without repetitive domains.
From the given relation, there are no repetitive domains. Thus our relation here is a function.
Example of Function
{(1,1), (2,2), (3,3), (4,4), (5,5)}
Example of Non-Function
{(1,1), (1,2), (2,3), (3,4), (4,5)}
From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

Answer:
x={-4,-1,0,3}
Step-by-step explanation:
(x²-3x)√x²+5x+4=0
x(x-3)=0
√x²+5x+4=0
x(x-3)=0
x=0
x-3=0
x=3
√x²+5x+4=0
x²+5x+4=0 (square both sides)
x²+4x+x+4=0
x(x+4)+1(x+4)=0

Alex counted to 2400 by 6's beginning with 6. Matthew counted to 2400 by 4's starting with 4. How many of the numbers counted by Alex were also counted by Matthew?
Answer: 200
Step-by-step explanation:
Number of numbers counted by Alex;
= 2,400 / 6
= 400
Number of numbers counted by Matthew;
= 2,400/4
= 600
Numbers that both of them counted = 600 - 400
= 200
What biotic factors do the organisms in Movile Cave rely on?
Answer:
Step-by-step explanation:
Trees or grasses may be growing around the entrance of the cave, and there might possibly be rocks around the side as well.
The most common plants in caves usually grow in the most moist parts and they are:
- Mosses (small flowerless plants that usually grow in dense green clumps or mats, in damp or shady locations)
- Ferns (flowerless plant that has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds. Ferns have a vascular system for the transport of water and nutrients.)
- Liverworts (small flowerless green plant with leaf like stems or lobed leaves, occurring in moist habitats. Liverworts lack true roots and reproduce by means of spores released from capsules.)
These species can live at the entrance zone or in the twilight zone.
If you go into the twilight zone, cyanobacteria (a bacteria that has chlorophyll) causes all the rocks facing the entrance to be a shade of green.
All cave animals and organisms fit into three categories. Placement into these categories depends on how much time the organisms actually spends in the cave.
The first type are known as Trogloxenes. You can think of trogloxenes as cave vistors. They come and go at will, but use the cave for specific parts of their life cycle (hibernation, giving birth, etc.) Although it spends specific parts of their life in the cave, it will never spend a complete life cycle in the cave. Examples of animals that are trogloxenes are:
-Bats
-Bears
-Skunks
-Raccoon
-Moths (sometimes)
Troglophiles are the next level. These are organisms that survive outside the cave, but may prefer to live outside of it. They leave the cave only in search for food. A troglophiles can chose to live its entire life either inside or outside of a cave. Some examples of trogphiles are:
-Beetles
-Worms
-Frogs
-Salamanders
-Crickets
-Spiders
-Crayfish (sometimes)
Troglobites are animals that live in the cave but do not come out. They often have physical adaptions to the cave life like no vision, or loss pigment because light does not reach this part of the cave. Examples would be
-Snails that have thin white shells and small eyes
-Blind cave fish which has no eyes and no color
-Kauai Cave Wolf Spider which also has no eyes.
Bats are not true troglobites because they only use the cave for sleep, hiding and reproduction. There is about 50 000 troglobites in the world.
A bats habitat and niche would be inside of a cave, in the Twilight zone. The twilight zone is located in the middle of the cave, where some sunlight reaches. Because the bats aren’t so far back in the cave they would be able to leave the cave easy at night, in order to catch their prey, but aren’t so close to the front that they can’t sleep during the day because of the sunlight.
One way for food to get into the cave is through natural weather events such as a flood. Excess rainwater washes leaves, twigs, plants, etc. into a cave. This brings in food for insects and other animals. Another way food enters a cave is simply through animals, they bring it in. If times get hard in the cave, the organisms living in it can feed on each other. An example would be listed below which is how some centipedes grow large enough to feed on bats. Another source of food is guano.
how do I find the dimensions of my square
To find the area of a square or a rectangle, you would multiply the value of the length by the value of the width.
length x width = area
1. Measure the length of the paper (the length, in this case, is the longest part of the paper).
2. Measure the width of the paper (the horizontal, shorter part of the paper).
3. Multiply said values together to find the area with your chosen system of units.
However, if you are looking for exclusively the length and/or width, you can use a ruler to find said dimensions.
