The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
Answer:
Step-by-step explanation:
Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m
Circumference of roller = 1.68π m
Contact area of roller = 1.68π × 2.8 = 4.704π m²
Each rotation levels 4.704π m² of the playground.
Area of playground = 750 rotations × (4.704π m²)/rotation
= 3528π m²
≈ 11,084 m²
The answer to your question is 5,000.

X= 6/7
Step-by-step explanation:
Answer:
63 feet of ribbon
Step-by-step explanation:
First, you find the unit rate by dividing 36 by 12. That gets you 3 feet of ribbon per package. Since you need to find how many feet of ribbon are in 21 packages, you multiply 21 and 3. 21x3= 63
