Answer:
s = 5.1
Step-by-step explanation:

Multiply both sides of the equation by 10

Expand

Subtract 28 from both sides

Simplify

Divide both sides of the equation by 10

Simplify

Answer:
Step-by-step explanation:
slope, m = 0.1m/4m = 0.025
Theoretical effort (ignoring friction) = 9000N * 0.025 = 225 N
actual effort = 300 N
efficiency
= potential energy out / actual energy in
= 225 N / 300 N = 0.75
Answer:
-15pi = irrational
square root of -3 = irrational
square root of -4 = rational
-1/11 = rational
-27.92 repeated = rational
Step-by-step explanation:
<u>Given</u>:
The given triangle is a right angled triangle.
The length of the hypotenuse is 17 units.
One of the legs of the triangle measure x units.
The one of the angles of the right triangle is 60°
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trigonometric ratio.
Thus, we have;

Substituting
,
and
in the above formula, we get;

Multiplying both sides of the equation by 17, we get;

Simplifying, we get;

Multiplying, we get;

Rounding off to the nearest tenth, we get;

Thus, the value of x is 14.7
