Answer:
x ≅ 7
Step-by-step explanation:
cos(67°) = x/18
x = 18cos(67°) ≅ 7
Answer: no it is not
Step-by-step explanation: any number that repeats forever cannot be written as a rational way or a fraction. So it is not rational.
Answer:
Survey
Step-by-step explanation: A survey is a research method of collecting data from a particular target group through questions aimed at extracting specific information from them
18 and 35. The numbers whose sum 53 are 18 and 35.
The key to solve this problem is using a system of equations.
There are two numbers whose sum is 53. This number can be represented as x and y. So:
x + y = 53
Three times the smaller number is equal to 19 more than the larger. Let's set x as the smaller number and y the larger number. So:
3x = 19 + y
Clear y in both equations and let's use the equalization method to solve for x:
y = 53 - x and y = 3x - 19
Then,
53 - x = 3x - 19
53 + 19 = 3x + x ---------> 3x + x = 53 + 19 -------> 4x = 72
x = 72/4 = 18
To find y, let's substitute x = 18 in the equation x + y = 53
18 + y = 53 --------> y = 53 - 18
y = 35
