Answer:
45 customers
Step-by-step explanation:
Given
Total number of customers = 125
percent that paid with credit card = 64%
Customers that paid with credit card = 64% * 125
Customers that paid with credit card = 0.64 * 125 = 80
Number of customers that paid with cash = 125 - 80
Number of customers that paid with cash = 45 customers
360 - because a right angle is 90° and there are 4 right angles in a circle , 90 x 4 = 360
Solution:
we are given that
Each cow has 4 legs and each chicken has 2 legs.
A boy counts 42 heads and 144 feet.
we have been asked to find how many cows are there?
Let there are x cows and y chicken.
Then we can write
Hence Number of cows=30
Answer:
The range of cos(x) is -1 to 1 (with brackets if in interval notation as -1 and 1 can be included) is because the radius of the unit circle is also 1. If the range went past -1 or 1, the unit circle could not define those values, and would turn up as error or undefined. Now, if you replace <em>a </em>in y = acos(x) + b, the range would be different because you amplified the equation and thus the range and radius.
Step-by-step explanation:
Answer:
0.5* sin(x)
Step-by-step explanation:
As well known sin (2A)= 2sin(A)*cos(A)
As in our case A=x/2 => cos(x/2*sin(x/2)=1/2*sin(x)=0.5*sin(x)
