Answer:
B.64
Step-by-step explanation:
75% of a number is 120.
Let's take "x" be the number.
75% of x = 120
75/100 * x = 120
0.75x = 120
x = 120/0.75
x = 160
So the number is 160.
Now we have to find the 40% of the number 160.
= 40/100 * 160
= 0.4 *160
= 64
40% of the number is B.64
Thank you.

Answer:
Option b.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
h(t) = cos (t +1)
Please, see attached picture below.
By looking at the picture, we can tell that the amplitude is equal to 1
The function has a period of T = 2π
We can see there is no vertical shift.
It has a phase shift of +1. (Which moves the graph to the left)
Answer:
Option b.
Answer:
D
Step-by-step explanation:
only b and d have the equation equal on both sides
and only D has it that 5 is the hypotenuse, and the opposite angle is 90 degrees
Let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
