Mia paddled her canoe from the shore of a lake to an island. She stopped on the island to eat lunch, and then paddled her canoe back to the shore. The graph below shows Mia’s distance, in kilometers, from the shore over time. Based on the graph, which of the following statements is true?
Answers
It took Mia 40 minutes to get to the island, 30 minutes eating lunch, and 30 minutes back.
The speed of Mia on the way back to the shore is greater than speed on the way to the island
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed on the way to the island be S₁
Let the speed on the way back to the shore be S₂
where the Speed = Distance / Time
So , S₁ = ( 3 - 0 ) / ( 40 - 0 )
S₁ = 3/40 km/minutes
S₁ = 0.075 km/minutes
And , S₂ = 0.1 km/minutes
Now , S₂ > S₁
Hence , the speed on the way back to the shore is greater

Answers
Answer:
Since J = 3, K = 6, and M = 12, the equation means:
(3 • 6) + (4 • 12 ÷ 2) = ???
Step-by-step explanation:
This is because when variables are next to each other and we know what they are equal to, it is the same as saying 3 • 6. So, when two variables are next to each other, they are being multiplied. Same with 4m/2. / can also mean division. And since 4 is next to m, the two are being multiplied. All together, the answer to this equation is 42. Hope this helped!
Answer:
(3*6) +((4*12)/2)
Step-by-step explanation:
j=3 k=6 M=12
two variables next to each other is multiplication
and use order of operations (PEMDAS)
42 is the answer

Javier walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Javier first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
How many minutes before Javier arrived was the water tank completely full? Explain or show your reasoning.
Answers
Answer:1) Gallons per minute change is -2/3 gallons per minute since it decreases by 2 gallons in 3 minutes
2) we have 5 gallons and lose 2/3 gallons per minute
(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) There were 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before Jada arrived.

what are the four parts of mathematical system?
Answers
Answer:
Structure of Mathematical Systems Mathematics can be divided into four major areas- higher arithmetic, algebra, geometry, and analysis.
Answer:
Sorry I didn't get the answer option first
Step-by-step explanation:
higher arithmetic, algebra, geometry, and analysis.
Arithmetic: It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations- addition, subtraction, multiplication, and division, between them.
Algebra: It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented by letters of the English alphabet such as X, Y, A, B, etc. or symbols. The use of letters helps us to generalize the formulas and rules and also helps you find the unknown missing values in the algebraic expressions and equations.
Geometry: It is the most practical branch of mathematics that deals with shapes and sizes of figures and their properties. The basic elements of geometry are points, lines, angles, surfaces and solids.
There are some other branches of mathematics that you would deal with in the higher classes.
Trigonometry: Derived from two Greek terms, i.e., trigon (means a triangle) and metron (means measurement), it is the study of relationships between angles and sides of triangles.
Analysis: It is the branch that deals with the study of the rate of change in different quantities. Calculus forms the base of analysis.

Answers
Answer:
so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.
p-7/12>3/10
add 7/12 to both sides
p>7/12+3/10
p>35/60+18/60
p>53/60
so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right

Answers
Answer:
240cm²
Step-by-step explanation:
area of a triangle:
½ x b x h
= ½ x 6 x 4
= 3 x 4
= 12.
since there are 8 of the same triangles, they will all have the same area. so to work out the total area of a triangles, we times the area of one triangle by the 8 triangles in the polygon.
12 x 8 = 96.
for the square in the middle:
area of a square = length x width
area of a square = 12 x 12 = 144.
all we need to do is add these two totals together.
144 + 96 =240cm².
we use the units cm², because we have been multiplying xcm x ycm which can be simplified to cm² :)

Explanation:
a) burritos are the independent variable because it is labeled as x. X will always be the independent variable. The reason I am confused is because all throughout my learning I was told "time" will always be independent and it had always proved to be true. I would just go with burritos though.
b) linear function is y=0.75x, with 0.75 being the slope representing the amount of time taken to make x amount of burritos. I see you already did most of the work! You just have to remember that to find slope (or m), that you do change in y/change in x.
c) when graphing, draw a point at the origin, (0,0). Then count 0.75 units up, and move 1 unit to the right. Your line should be from left to right going "upward".
d) your answer for d is correct
