A rectangular block of metal is 25cm long, 11cm wide and 9cm high. The metal block is melted down and all of the metal is used to make a cube. Work out the length of each side of the new cube formed
Answers
Answer:
29.03 cm
Step-by-step explanation:
Step one:
given
A rectangular block of metal is
25cm long
11cm wide and
9cm high.
The volume of the block is
= 25*11*9
= 2475cm^3
Required
The dimension of an equivalent cube
we know that volume of cube
v=l^3
24475=l^3
cube root both sides
l= ∛24475
l= 29.03 cm
Answer:
13.5cm

1. Simplify:
-2(n + 3) = 13
-2n - 6 = 13
2. Change „-6” side to right (to get answer), without forgetting to change the sign:
-2n - 6 = 13
-2n = 13 + 6
-2n = 19
3. Simplify (The „|” means operation done at both sides of equation):
-2n = 19 |:(-2)
n = -9.5
Proof:
-2(-9.5 + 3) = -2 * (-6.5) = 13

Answer:
sin α = =
cos α = =
tan α = =
cot α = =
sec α = =
csc α = =
Step-by-step explanation:
If the point is given on the terminal side of an angle, then:
Calculate the distance between the point given and the origin:
r =
Here it is: =
=
So we have:
x = 3
y = 1
r =
Now we can calculate all 6 trig, functions:
sin α = =
cos α = =
tan α = =
cot α = =
sec α = =
csc α = =
Final answer:
The question involves calculating the six trigonometric functions (Sin, Cos, Tan, Csc, Sec, Cot) for an angle in standard position with its terminal side passing through point (3,1). We find opposite and adjacent sides from the point's coordinates, the hypotenuse from Pythagoras' theorem, and calculate each ratio accordingly.
Explanation:
In the context of the problem, the point (3,1) specifies the terminal side of angle θ in standard position. This point is effectively the definition of your right triangle's opposite (y) and adjacent (x) sides in the trigonometric calculation, with the hypotenuse (h) obtained from Pythagoras' Theorem (h² = y² + x²). In this case, we get h = sqrt(3² + 1²) = sqrt(10).
The six trigonometric functions are defined as follows for this scenario:
- Sin θ = y/h = 1/sqrt(10).
- Cos θ = x/h = 3/sqrt(10).
- Tan θ = y/x = 1/3.
- Csc θ = 1/sin θ = sqrt(10).
- Sec θ = 1/cos θ = sqrt(10)/3.
- Cot θ = 1/tan θ = 3.
