Volume (V) is (=) Length (L) times (x) Width (W) times (x) Height (H) so V = L x V x H.
Add the variables to the equation.
V = 24 x 10 x 13
Solve
V = 3120
So the volume of the gift box is 3120 cm
I think in this situation the best method would be a guess and check. You know that there are 8 dimes more than there are nickels. So just keep increasing each number by one until you reach $1.40. If there were 9 dimes and 1 nickels it would add up to $0.95. If there were 10 dimes and 2 nickels, it would add up to $1.10. If there were 11 dimes and 3 nickels, it would add up to $1.25. If there were 12 dimes and 4 nickels, it would add up to $1.40. So your answer is 12 dimes and 4 nickels.
I hope this helped!
T = 3π/2
Let's transform 3π/2 on degree
We know, π = 180° on trigonometric
Then,
3π / 2 = 3.(180°)/2
3π / 2 = 270°
Now let's evaluate.
Sin(270°) = Sin(-90°)
As Sin(-x) = - Sin(x)
Then,
= - Sin(90°)
= - 1
It is possible
_______________
2 example:
Csc(270°) = ?
As Csc(x) = 1 / Sin(x)
Then,
Csc(270°) = 1 / Sin(270°)
= 1 / - 1
= -1
It is possible
_____________
3 example:
Cos(270°) = Cos(-90°)
As Cos( -x) = Cos(x)
Then,
= Cos(90°)
= 0
_______________
4 example:
Sec(270°) = ?
As Sec(x) = 1 / Cos(x)
Then,
Sec(270°) = 1 / Cos(270°)
= 1 / 0
It isn't possible division by zero
______________
5 example
Tg(270°) = ?
As Tg(x) = Sin(x) / Cos(x)
Then,
Tg(270°) = Sin(270°) / Cos(270°)
= - 1 / 0
It isn't possible too.
______________
Now the six and last example
Cot (270°) = ?
As Cot(x) = 1 / tg(x)
Cotg (x) = Cos(x) / Sin(x)
Then,
Cot(270°) = Cos(270°) / Sin(270°)
= 0 / -1
= 0
It is possible
Answer:
Step-by-step explanation:
∠A - Angle can also be named by the vertex holding the angle.
∠TAR
∠RAT
See my previous answer to this same question. the vertical angles have to be right angles
