Well, there's 360 degrees in a full circle.
If the hand moves 1/4 of a complete revolution, divide 360 by 4.
The minute hand moved 90 degrees.
Answer:
The Definition of Inverse Operations
A pair of inverse operations is defined as two operations that will be performed on a number or. variable, that always results in the original number or variable. Another way to think of this is. that the two inverse operations “undo” each other.
Example: Addition and subtraction are inverse operations.
Hey there :)
We know the area formula of a triangle
We are given:
The area = 56 m²
The base = let p represent this
The height = 9 m less than the base = p - 9
Apply the formula
56 =
× ( p ) × ( p - 9 )
56 =
× ( p² - 9p )
Divide
on both sides
56 ÷
= p² - 9p
112 = p² - 9p
Bring 112 to the other side and equate equation to 0
p² - 9p - 112
Factorise { Sum = -9 , Product = - 112 , therefore suitable factors = - 16 × 7 )
( p - 16 )( p + 7 ) = 0
↓ ↓
p = 16 p = - 7 ← Reject p = - 7 since length cannot be negative
So, the length of the base is 16 mCheck:
56 m² =
× 16 × ( 16 - 9 )
56 m² = 8 × 7
56 m² = 56 m²
43/5 this is an improper fraction so we will convert it to a mixed number...
(40+3)/5
8+3/5
So he can make 8 complete groups and will have 3 left over.
