Answer:
125 traffic cones
Step-by-step explanation:
In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:
, where 'x' is the number of meters
cross-multiply: x = 25(50) or x = 1250 m
Since there is a cone every 10 m, we can divide the total number of meters by 10:
1250/10 = 125 cones
Answer:
In disguise right arrow In Standard Form a, b and c
x2 = 3x − 1 Move all terms to left hand side x2 − 3x + 1 = 0 a=1, b=−3, c=1
2(w2 − 2w) = 5 Expand (undo the brackets),
and move 5 to left 2w2 − 4w − 5 = 0 a=2, b=−4, c=−5
z(z−1) = 3 Expand, and move 3 to left z2 − z − 3 = 0 a=1, b=−1, c=−3

Answer:
4/13 is the probability does a blue Jelly Bean is selected
Step-by-step explanation:
sample space = sum of all the jelly beans in the bag
sample space =5+6+7+8
sample space =26
probability = Jelly Bean selected / sample space
probability =8/26
probability =4/13
