Answer:
45 dimes
Step-by-step explanation:
66 nickels = 66 x $0.5 = $3.30
$7.80 - $3.30 = $4.50
$4.50 / $0.10 = 45
Answer: (x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!
P(A&B)=6/223×6/223=36/49729=0.0007239 approx (0.0724% approx).
Answer:
x = 4
, y = 2![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
x = 4![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
-------------------------------------------------------------------
Using the tangent ratio in the right triangle and the exact value
tan30° =
, then
tan30° =
=
=
( cross- multiply )
y = 2![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
