Answer:
Mai was moving faster.
As, she covered a greater distance in the same amount of time.
Step-by-step explanation:
Given: Mai traveled 15 meters in 6 seconds and Priya travels 22 meters in 10 second.
Calculate the speed of both;
Speed defined as the rate at which an object covers distance.
Mai traveled 15 meters in 6 seconds
then;
Speed = 
Priya travels 22 meters in 10 second.
then;
Speed = 
Reason: Mai traveled faster because she covered a greater distance in the same amount of time.
Answer:
Find out the how much chlorine is in the pool .
To prove
As given
The amount of chlorine in a swimming pool varies directly with the volume of water.
The pool has 2.5 milligrams of chlorine per liter of water.
i.e
2.5 milligrams of chorine = 1 litre of water
There are 8000 gallons of water in the swimming pool.
As 1 gallons = 3.78541 litre (Approx)
Now convert 8000 gallons of water in litres.
8000 gallons = 8000 × 3.78541 litre
= 30283.28 litres
Now calculate chlorine in the pool for 30283.28 litres of waters.
As
2.5 milligrams of chlorine = 1 litre of water
2.5 × 30283.28 milligrams of chlorine = 30283.28 litre of water
75708.2 milligrams of chlorine for 30283.28 litre of water .
82.15 / 31 = 2.65 per gallon
Answer:A not b or c or d A!!
Step-by-step explanation:
Answer:
(3x + 1)²
Step-by-step explanation:
Given
9x² + 6x + 1 ← is a perfect square of the form
(ax + b)² = a²x² + 2abx + b²
Compare like terms to find a and b
a²x² = 9x² ⇒ a² = 9 ⇒ a = 
= 3
b² = 1 ⇒ b = 
= 1
and 2ab = 2 × 3 × 1 = 6
Thus
9x² + 6x + 1 = (3x + 1)²
