1. true or false? this figure only has one line of symmetry.

1. find the coordinates of: spade symbol

1. if you spin the spinner, on what color are you most likely to land?

1. how many equal line segments are needed to make a row of 6 triangles?

Explanation:

Step1: Solve Question 1

$$19 + 8 = 27$$

Step2: Solve Question 2

$$5 \times 7 = 35$$

Step3: Solve Question 3

$$81 \div 9 = 9$$

Step4: Solve Question 4

$$358 \approx 400$$

Step5: Solve Question 5

$$0.5 \times 2 = 1$$

Step6: Solve Question 6

$$8 - (10 \div 2) = 8 - 5 = 3$$

Step7: Solve Question 7

$$7 \times 7 = 49$$

Step8: Solve Question 8

$$4 \times 60 = 240$$

Step9: Solve Question 9

A square has four lines of symmetry, so the statement is false.

Step10: Solve Question 10

The spade symbol is located at column C and row 5, which is (C, 5).

Step11: Solve Question 11

The red section covers half of the spinner, making it the most likely.

Step12: Solve Question 12

$$3 + 5 \times 2 = 13$$

Answer:

1. 27
2. 35
3. 9
4. 400
5. 1
6. 3
7. 7
8. 240
9. False
10. (C, 5)
11. red
12. 13
