What is x? Options: 81, 57, 143, 66.
jeyben [28]

Answer:

x = 103

Step-by-step explanation:

In my opinion, because x and 77 are the supplementary angles, so 180-77 = x or x+77=180. The answer should be 103......even though it's not in the options (I'm sorry).

George walked around the entire perimeter of his rectangular garden. The length of his garden was 12 yards and the width was 8 y
Marina86 [1]
To find perimeter, you use this equation for a parallelogram:
2l+2w=p
Let’s not put the numbers in,
2(12)+2(8)
24+16
40
So b, 40 yards is how much he walked.

In a factory, the chance that a certain machine works without overheating in the morning is 50%. If it runs smoothly all morning
sammy [17]
Let's imagine that we turn the machine on 100 times. (this will make the percent conversion easier)

the chance that works in the morning is 50%  of 100 so it will work 50 times.

the chance that it will then continue for the rest of the day is 15% so 15%*50 (the number of times it worked), which is 7.5 times.

our times actually represented percent, so the answer is : 7.5%!
