Answer:
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53
Answer:
1. 1 kg =2.20462poud
so 12kg= 26.4555pound
2. 1 meter=39.3701inches
so a 100 meter is 3937.01 inches
i hope you understand i hope you do better in your grades

Step-by-step explanation:
Answer:
32 trucks.
Step-by-step explanation:
3:1
Every time 3 SUV's are sold, one truck is sold. This would also mean that 
of both trucks and SUV's sold are SUV's. If we divide 128 into fourths, then you get 32. One fourth of 128 is 32. So, they should have 32 trucks (and 96 SUV's)
Answer:
3. 11 (B)
6. (-2, 18) (D)
8. I see the answer choices now, it would be A.
I don't see any answer options, but anything that goes along the lines of the points form a line, it has a direct relationship, it is linear, etc.
Step-by-step explanation:
3. You are given the expression 6x^2 - 13 and told to evaluate it at x = 2
this yields 6(2)^2 -13 which is 24-13 = 11.
6. You are given the equation y = -9x and 4 choices for ordered pairs. Best way to do this is to plug in the values and see which one works. (But if you want to do this quick you realize that the since you are multiplying one of the values by a -9 this means that the signs of the ordered pair has to be opposite and that only occurs in D (-2, 18) Plug it in and it works.
8. Each time you pay for the meter, it costs $1 or 4 quarters. And you pay per hour. Therefore if the x - axis is time (hours) and the y axis was the number of quarters, you can see that for 1 hour you pay 4 quarters, 2 hours you pay 8 quarters, 3 hours you pay 12 quarters, etc.
You can connect the dots on the graph and you can see that it is linear, you can also verify this by finding the slope between each point and find that the slope (change in y / change in x) is all the same.
Answer:
Answer is D. 98500 and 4000
Refer below.
Step-by-step explanation:
The average salary of a travel management professional is $98,500. Assume that the standard deviation of such salaries is $40,000. A random sample of 100 travel management professionals are selected, then the mean and standard deviation of the sampling mean is 98500 and 4000.
