What is this percent of change 40;72
Answers
Original or base : 40
New amount : 72
We need to find the difference of the new amount and the original amount
72 - 40 = 32
We then divide the difference by the original amount
32/40 = 0.80
We multiply the quotient by 100%
0.80 x 100% = 80%
The percentage of change is 80%

Answers
Answer:
A
Step-by-step explanation:
The secant- tangent angle 78° is half the difference of the intercepted arcs
(204 - x) = 78 ( multiply both sides by 2 )
204 - x = 156 ( subtract 204 from both sides )
- x = - 48 ( multiply both sides by - 1 )
x = 48

The correct option is D.
Important information:
- Each graph has two lines.
Perpendicular lines:
Two lines are called perpendicular lines if the angle between those lines at the intersection point is 90 degrees.
In option A, the lines are parallel because they have the same direction and slope.
In option B, if we increase the lines, then they can not make a 90-degree angle.
In option C, the lines are not making a 90-degree angle.
In option D, the lines are perpendicular because they are making a 90-degree angle.
Therefore, the correct option is D.

Sparrow has 92 coins, in the starting.
What is ratio?
Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Total number of coins in game = 210.
And the ratio of coins belongs to Ahab, Sparrow and Davy = 4 : 5 : 6
Let the multiplying factor in ration is x
The number of coins to Ahab = 4x
Number of coins belongs to Sparrow = 5x
And number of coins belong to Davy = 6x
Since, total number of coins = 210
4x + 5x + 6x = 210
15x = 210
x = 16
Number of coins that Sparrow has = 5 x = 5 (16) = 80
At the end Ahab and Davy wins 5 and 7 coins respectively
So at the starting coins that Sparrow has = 80 + 7 + 5 = 92
The required coins that Sparrow has at the beginning is 92.
