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
For six you can write 1/4 because there is 4 pennies and 1 represents each penny
for number 5 you can put 2/10 because there is 10 coins and 2 quarters
and for number 7 is that Bradley has 10 coins not 9 so it would be 1/10
The correct answer is C. I just took a test and answered B but that is not the correct answer. it is actually C
Answer:
They would recieve cents as change.
Step-by-step explanation:
They bought 2 sandwiches, 1 salad, 1 piece of fruit and 2 drinks
Total = 6 items altogether
They gave cashier cash of 20.03
Which means all items are not more 20.03
If they would receive change, it would be in cents.
