First of all change <span>milliliters</span> to litres.
1500 ml = 1,5 l
Now,
you know that 7,5 l = 100% (the whole amound)
and you are asking how much is: 1,5 l of the whole, so you got:
7,5 = 100%
1,5 = x%
7,5 x = 150
x = 150 / 7,5
x = 20%
Answer: 1500 ml is a 20% of the 7,5 litres.
One irrational number between 5 and 7 is
.
If what you mean by the "percent of people 50 years old belong to group A" is the percentage of 50-year old people with respect to the total number of people belonging to group A, then the answer is
32/(19+32) * 100 = 63%
But, if what you mean is the percentage of 50-year old people in group A with respect to the total number of 50-year old people, then the answer will be
32/(32+24) * 100 = 57%
Domain is another word for the x value. so, this question just asking us to solve for y when x = 7
first, substitute in x
y = 3(7) -4
and then solve for y
y = 21 - 4
y = 17
so, the range is 17 when the domain is 7
<span> i think its -x+5/6x^2-x-12 but i might be wrong.....</span>
