Answer:
The present age of son is 7
Step-by-step explanation:
Let the son age be x
One year ago
Son's age = x - 1
Therefore man's age = 8(x-1) =8x - 8
Now man's age = x^2
Difference between both ages if man =1 years
So
x^2 -(8x-8) = 1
x^2-8x + 8-1 =0
x^2- 8x + 7 = 0
x^2 - 7x -x + 7 = 0
X(x-7) - 7 ( x - 7) = 0
(x - 1) ( x - 7) = 0
x = 1, 7
But son cannot be 1 years
Therefore ,
x = 7
SO,
age of son is <em>7</em>
age of father is x×7=<em>49</em>

Answer:
Alicia is the golfer who has had the lowest number of strokes per hole
Step-by-step explanation:
we know that
The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes
Let
x ----> the number of strokes
y ----> the number of holes
we have
<em>Roy</em>
<em>Alicia</em>
<em>Rickie</em>
Compare
4.39 < 4.56 < 4.67
therefore
Alicia is the golfer who has had the lowest number of strokes per hole
V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a
r=3
h=2a
v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ
so the expression would be some variaant of v=6aπ
40 hours/week * 52 weeks = 2,080 hours a year.
$30,000/year
$15.00/hour * 2,080 hours = 31,200/year
$30,000/year w/ a 10% bonus = 30,000 * 1.10 = 33,000/year
$15.00/hour and a $2,000 bonus at the end of the year = (15 * 2,080) + 2,000 = 31,200 + 2,000 = 33,200/year
I will earn the most in $15.00/hour and a $2,000 bonus at the end of the year. I will earn $33,200 per year.
