1. The correct answer among the choices provided is the first option. It is a geometric sequence and the common ratio is 2.
2. Fifth term in the geometric sequence is 405. The pattern in this sequence is to triple the last term to get the next answer.
Part 1:
Variable x - number of the hours.
Variable y - her total income.
y = f ( x ), Her total income is a function of the hours she worked.
Part 2 :
The function is: y = 15 * x
Part 3 :
f ( 35 ) = 15 * 35 = $525
f ( 29 ) = 15 * 29 = $435
Week 1 : Ashley worked 35 hours. She earned $525.
Week 2: Ashley worked 29 hours. She earned $435.
Answer:
mp=sp+25%ofsp=1.25sp
mp=1.25sp
sp=1/1.25×mp=0.8mp
cp=mp-30%ofmp=0.7mp
discount=mp-sp=mp-0.8mp=0.2mp
- discount %=discount/mp×100%=0.2mp/mp×100%=20%
- profit=sp-cp=0.8mp-0.7mp=0.1mp
- profit%=profit/cp×100%=0.1mp/0.7mp×100%=0.1×100/0.7%=10/0.7%=14.28%

I might be wrong though
have fun with it</span>
In the first example we must calculate hypotenuse's length using pythagorean theorem
c^2 = a^2 + b^2 => c^2 = 24^2 + 6^2 = 576 + 36 = 612 =>
c = square root of 612 + 24.74 ft
perimeter P1 = a+b+c = 24+6+24.74= 54.74 ft
In the second example we must calculate second leg in the same manner
a^2 = c^2 - b^2 => a^2 = 15^2 - 9^2 = 225 - 81 = 144 =>
a = square root of 144 = 12
perimeter P2= 15+9+12=36 ft
Good luck !!!!
