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: Height of the water is 20 cm.
Step-by-step explanation:
Since we have given that
Base area = 100 square cm
volume of vase shaped like an octogonal prism = 2 liters
We need to find the height of water.
and 1 liter = 1000 cm³
2 liters = 2×1000 cm³
As we know the formula for "Volume":

Hence, height of the water is 20 cm.
Answer: $384.13 ( rounded)
Original number: $384.125
Step-by-step explanation:
Find 9.75% of Paul's original stock, to find out how much it increased.

$384.125
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
