a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm
8.125/2 = 4.0625 x 192 = 780 cm
5/2 = 2.5 x 192 = 480 cm
Actual dimensions: 780 cm by 480 cm
Divide by 100 to convert to meters:
780/100 = 7.8 meters
480/100 = 4.8 meters
b: area of a triangle = 1/2 x base x height
area = 1/2 x 480 x 780 = 187,200 square cm
1/2 x 7.8 x 4.8 = 18.72 square meters
i did the dimensions in both cm’s and meters
Answer:
For A i would put 64 because its basically doing the total wing size divided by the number of sides it has.. And for B i havent thought of that yet..
Step-by-step explanation:
Hope this helps a little bit

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.

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 :)

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.

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)

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".

Select from the drop-down menu to correctly classify the triangle.
A triangle with angle measures of 30° and 40° is
Acute
obtuse
right
Answers
Step-by-step explanation:
The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!
