the sum of supplementary angles equals 180°
you can have an acute angle (less than 90°) + an obtuse angle (greater than 90°) equal to 180°
But you can also have a right angle (equal to 90°) + another right angle equal to 180°
Answer: (b) sometimes
Answer:
I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)
<u><em>The variable is the number of shirts she bought or x</em></u>
and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>
in the solve spot put
<em><u>(375+50) divided by (15+2)=x</u></em>
<em><u>425 divided by 17=x</u></em>
<em><u>x=25</u></em>
Then your answer would be <u><em>25</em></u>
Step-by-step explanation:
first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.
The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28
Answer:
Step-by-step explanation:
you add two angles and then subtract it from 180 degrees
Hopefully it is right
for example: A angle+B angle-180 degrees
Answer:
700 lbs and 3.742
Step-by-step explanation:
Given that raw materials are studied for contamination. Suppose that the number of particles of contamination per pound of material is a Poisson random variable with a mean of 0.02 particle per pound.
a) To get 14 particles of contamination we must have
expected number of pounds = 
b) Since for 700 pounds particles expected are 14 we can say in a Poisson distribution mean and variance are equal
i.e. Var (700 lbs to obtain 14 particles of contamination ) = 14
Std deviation =
