Answer:
Seth has 21 nickels
Step-by-step explanation:
Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.
Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then
Solve this equation:
The answer to this question is D
Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16
Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856
Answer:
x = {-0.454, 15.954}
Step-by-step explanation:
we can solve this equation by putting it into the quadratic formula
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-248 +/- sqrt(248^2 - 4(-16)(116))] / 2(-16)
x = [-248 +/- sqrt(61504 + 7424)] / -32
x = [-248 +/- sqrt(68928)] / -32
x = (-248 +/- 262.541425) / -32
x = (-248 + 262.541425) / -32
x = (-248 - 262.541425) / -32
x = {-0.454419531, 15.9544195}
rounding to the nearest thousandth would make it x = {-0.454, 15.954}
