1 answer:
Answer:
Richard is making $9.6 per hour now
Step-by-step explanation:
Given:
Initial amount Richard was earning = $10/hr
Due to lass in productivity 20% pay was cut
Amount Richard was earning after 20% pay cut = $8/hour.
After few again due to increase in productivity Diane gave a 20% raise.
To Find:
How much is Richard making now = ?
Solution:
Let the amount that Richard is making now be x
Then
x = 8+ 20% of 8
x =
x =
x =
x = 9.6

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).
Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.
Area of a square is length times width.

Answer:
The distance between the hands is √(3)cm ≈ 1.73cm.
Step-by-step explanation:
In a standard clock, the angle between every number is 30°, therefore the angle between 12 and 2 will be 30° x 2 = 60°.
Looking at the diagram, to find c we can make use of our cosine formula
c² = a² + b² –2abCos(C°)
a = 2, b = 1 and C° = 60°
Therefore we have:
c² = 2² + 1² –2 x 2 x 1 x cos(60°) =
c² = 4 + 1 – 4 x 0.5 =
c² = 5 – 2 =
c² = 3
c = √(3) ≈ 1.73
Therefore, the distance between the hands is √(3)cm ≈ 1.73cm.
