Answer:
P(water)=11/22=1/2
Step-by-step explanation:
The number of bottles with water is 11
The total number of bottles is 11 +9+2=22
Sothe probability that Ronald chooses a bottle of water is
P(water) =N(water)/N(total)=11/22=1/2
1) find the perfect square closest to the number
2) take that square root, and then divide your number by that number
3) take the average of the perfect square root (the whole number) and the result of dividing your original number by that root.
Example: Approximate square root of 27
Closest perfect square: 25
Square root: 5
27 ÷ 5 = 5.4
Average between 5 and 5.4 = 5.20
5.2² = 27.04. Fast and not a bad approximation!
Answer: the system of equations are
3x + 2y = 170
4x + 6y = 360
Step-by-step explanation:
Let x represent the price of a child's ticket in dollars.
Let y represent the price of an adult's ticket in dollars.
The Brown family paid 170 for 3 children and 2 adults. This would be expressed as
3x + 2y = 170
The Peckham family paid 360 for 4 children and 6 adults. This would be expressed as
4x + 6y = 360
Answer:
Step-by-step explanation:
Area of trapezium = 1/2 × h (a+b) = 864 cm^2
where h is the height and a and b are the two parallel sides
h = 24 cm
a = 30 cm
b = ?
1/2 × 24 ( 30 + b ) = 864
12 ( 30 + b ) = 864
30 + b = 864/12
30 + b = 72
b = 72 - 30
b = 42
Therefore the lenght of other base = 42 cm
