Answer:
3/8 or 0.375
Step-by-step explanation:
0.75/2 = 3/8
This question requires creating a few equations and working through them step-by-step. Now, first let's give each of the shapes a variable: let's say that the blue shape is a, the orange shape is b and the green shape is c.
1. We can technically create six formulas for the magic square, with three for sum of the rows and three for the sum of the columns, however the smartest way to approach this is to observe whether there are any obvious answers that we can get.
We can see in row 2 that there are three of the same shape (a) that add to 57. This makes it very simple to calculate the value of the shape.
Since 3a = 57
a = 57/3 = 19
2. Now we need to find a row or column that includes a and one other shape; we could choose either column 2 or 3, so let's go with column 2. Remembering that the blue shape is a and the orange shape is b:
2a + b = 50
Now, given that a = 19:
2(19) + b = 50
38 + b = 50
b = 12
3. We can now take any of the rows or columns that include the third shape (c) since we already know the values of the other two shapes. Let's take column 1:
a + b + c = 38
19 + 12 + c = 38
31 + c = 38
c = 38 - 31
c = 7
Thus, the value of the blue shape is 19, the value of the orange shape is 12 and the value of the green shape is 7.
Answer:
Wouldn't the third term be 21?
The vertex form of the equation of a parabola is given by

where (h, k) is the vertex of the parabola.
Given that the vertex of the parabola is (-12, -2), the equation of the parabola is given by

For a = 1,

parabola whose minimum is at (−12,−2) is given by the equation

, where a = 24 and b = 112.</span>
Answer:
0.33 liters of water Bao use per liter of flour.
3 liters of flour Bao use per liter of water
Step-by-step explanation:
Given the graph which pass through the coordinates (0,0) and (3,1)
∴ Equation of line passing through these points can be written as

⇒ 
⇒
⇒ 
Now, we have to find liters of water Bao use per liter of flour i.e if x=1 then we find the value of y which is 3y=x=1 ⇒ 
Now, we have to find liters of flour Bao use per liter of water i.e if y=1 the we have to find the value of x which is x=3 litre
