Answer:
90 minutes
Step-by-step explanation:
an hour is 60 minutes+ another 30 minutes= 90
The domain of (f/g)(x) considers the domains of g(x) and f(x) and makes sure that g(x)≠0
because (f/g)(x)=f(x)/g(x)
and division by 0 is not allowed
the domains of f(x) and g(x) are all real numbers
now find what make g(x)=0
0=x-9
9=x
9 is restricted from the domain
domain is all real numbers except 9
so


the domain is all real numbers except for 9
Iam not very sure but i think y=22.5
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :

Where
l and b are length and breadth
So,

The first possibillity for dimension is (10×24). Another can be (12×20).
Answer: 2.2464 × 10^8
Step-by-step explanation:
Percentage of obese Americans in 2011 - 2012 = 35%
Percentage of Americans who are adult = 72%
United States population estimate = 312 million
Adult = age 20 and above
Number of adult Americans (age 20 and above) :
72% of the total united states estimated population
72% of 312,000,000
72/100 × 312,000,000
0.72 × 312,000,000
= 224,640,000
Hence, estimated Adult American population (age 20 and above) = 224,640,000
2.2464 × 10^8
