<h3>
Answer: 37.5%</h3>
Work Shown:
9+15 = 24 students total
9 have glasses, so 9/24 = 0.375 = 37.5% of the class wears glasses.
Well since we know the roots are x = 5 and x = -1/4. We can convert it into an equation and make it equal to 0.
Simply work backwards instead of solving for x. For x = 5, it would be x - 5 = 0, because if you solve for x it will be 5.
Same thing for x = -1/4, the equation would be x + 1/4 = 0.
(X-5)(x+1/4) = 0.
Now multiply the 2 binomials together to get the quadratic. To get rid of the fraction after obtaining the quadratic multiply by 4 for each term in the quadratic.
Answer:
$4,738.82
Step-by-step explanation:
Using the compound interest formula expressed as;
A = P(1+r/n)^nt
P is the principal = $1800
r is the rate = 6% = 0.06
t is the total time = 18years
n is the time of compounding = 1/4 years
Substitute
A = 1800(1+0.06(4))^(18/4)
A = 1800(1+0.24)^4.5
A = 1800()1.24)^4.5
A = 1800(2.6327)
A = 4,738.82
Hence the amount in the account after 18years is $4,738.82
Answer:
x= 2/3 -1/3y or x= -1/3y + 2/3
Step-by-step explanation:
3x + y= 2 (subtract the y to get 3x by itself)
3x= 2-y (divide both sides by 3 to get x by itself)
x= 2/3 - 1/3y
