The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
Step-by-step explanation:
Given,
Cost of one box of raspberry scones = $15.00
Cost of one box of lemon poppy seed muffins = $9.00
Total boxes sold = 46
Total revenue earned = $396
Let,
x be the number of raspberry scones sold.
y be the number of lemon poppy seed muffins sold.
According to given statement;
x+y=46 Eqn 1
15x+9y=396 Eqn 2
The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
Answer:
Option 4, 64 cm^2
Step-by-step explanation:
The polygon in the shape of a star can be made to be easier to find the area of by cutting it into triangle. For all the "point edges" of the star, we can cut them in half from the vertex to create two right-angled triangles at each edge.
The formula of the area of a triangle is bh/2: the height is given as 6cm, the base is 4cm /2 (after you cut it in half) and so is 2 cm. Since the edges can be cut into two, there are 8 right angled triangles at the edges in total.
To find the area of them:
A=8(bh/2)=8(2*6/2)=48 cm^2
However, we are still missing the part at the centre we haven't found the area of, the square. The area of a square is given by the square of the side length(4cm). Thus, A=4*4=16cm^2
Adding the areas of all the edges and the square:
48 + 16 = 64cm^2
Hence, the area of the polygon is 64cm^2
