Javine says, "To multiply by 1000, I just add three zeros." Kian says, "I times by 10, then times by 10 and times by 10 again."
aksik [14]

Answer:

Kian's method is correct.

Step-by-step explanation:

Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.

Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.

10. Rotate the figure shown 180° clockwise. Record the coordinates of the 3 points<br> image.
inna [77]

Answer:

J' = (6,7)

K' = (6,2)

L'=(3,7)

Step-by-step explanation:

From the attachment, we have:

J = (-6,-7)

K = (-6,-2)

L = (-3,-7)

Rotation: 180 degrees clockwise

Required

Find J', K' and L'

When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)

So, we have:

J' = (6,7)

K' = (6,2)

L'=(3,7)
