I believe the answer would be 6:5 because you divide both 18 and 15 by 3.
1). The inequality says "height is 54 or more".
Any height that is less than 54 does NOT qualify.
2). The sign says "Maximum total weight 800 pounds".
Any weight that's 800 pounds or less is OK.
3). Paula has scored 21, 25, and 15 points.
. . . . . they're NOT all greater than 21
. . . . . they ARE all 25 or less
. . . . . they ARE all less than 30
. . . . . they ARE all 10 or more .
4). First, write down the number of cans that
each student collected, but arrange them in order.
Then check each choice.
A). misses the highest 3 students completely
B). includes everybody
C). misses the lowest 3 students completely
D). OK, but the first and last intervals aren't needed,
because nobody's cans are in those intervals
This is an increase and it increased by 40% because the difference between 140 and 100 is 40 which is 40% of 100.
Use order of operations PEMDAS
Here the parentheses are worked out first .
(27.45-14.61)-[12.53-36.75]
= (12.84) - (-24.22)
= 12.84 + 24.22
= 37.06 Answer
