Lucy draws a line on a coordinate plane. We have to identify the transformation which will always result in a line perpendicular to Lucy’s line.
Referring to the given options.
By rotating 270 degrees clockwise around the origin, Lucy will get a line perpendicular to the Lucy's line. As, when we rotate 270 degrees clockwise about the origin, we multiplies the x coordinate by '-1' and interchanges the x and y coordinate, which gives the line which is always perpendicular to the Lucy's given line.
56/4 divided by 2 » (56/4) ÷ 2 » 14 ÷ 2 = 7
Negative numbers are less than positive numbers
Answer:

Step-by-step explanation:
Answer:
302
Step-by-step explanation:
420(grams per sec)x60(seconds in a min) = 25,200(grams per min)
25,200x60(min in an hour) = 1,512,000(grams an hour)
1,512,000/1,000(grams in a kilogram) = 1,512 (kilograms per hour)
1,512/20 (size of bag) = 75.6 (bags filled per hour)
75.6x4(hours elapsed asked by the question) = 302 bags completly filled in 4 hours
