You would put these in a fraction then cross multiply so 15/1800 and 3/x then you get 5400 equals 15x then divide by 15 on both sides to get x equals 360
A pediatrician records the ages of the patients seen in one day: 1,2,5,7,9,17,13,16,18,12,3,5,1. Assuming that some of the patie

Pediatrician forgot to write down the value of the numbers whether months or years, maybe even days
Number 5 is 15.9 kilograms
And number 6 is 6 million cubic feet per minute
You just cross multiply
Answer:
1.125 gallons
Step-by-step explanation:
The first thing you do here is convert 9 quarts to gallons. To convert from quarts to gallons you dvide by 4. So 9/4=2.25.
The next thing you do is divide this number by two to achieve your answer
2.25/2=1.125
So the final answer you would be after using half of his paint Gary is left with 1.125 gallons of paint
Answer:
Step-by-step explanation:
Given that,
The arc length is four times the radius
Let he radius be 'r'
Then, the arc length be 's'
The arc of a sector can be calculated using
s=θ/360 × 2πr
Then, given that s=4r
So, 4r = θ × 2πr / 360
Divide both side r
4 = θ × 2π/360
Then, make θ subject of formula
θ × 2π = 360 × 4
θ = 360 × 4 / 2π
θ = 720 / π
So, area of the sector can be determine using
A = θ / 360 × πr²
Since r = ¼s
Then,
A = (θ/360) × π × (¼s)²
A = (θ/360) × π × (s²/16)
A = θ × π × s² / 360 × 16
Since θ = 720 / π
A = (720/π) × π × s² / 360 × 16
A = 720 × π × s² / 360 × 16 × π
A = s² / 8
Then,
s² = 8A
Then,
s= √(8A)
s = 2 √2•A
