They make 18 chicken burritos because when you do 24 beef burritos total divided by 4 beef burritos you get 6 beef then you muliply 6 by the number of chicken burrittos.
Answer: a iscolses triangle is 180 so add what ever numbers are there until you get 180 hope that help's

Answer:
![C = \pi (2x -2)](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%282x%20-2%29)
Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula
.
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.
![C = \pi (2x -2)](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%282x%20-2%29)
Using the distance formula we can determine the perimeter of PQR.
Distance formula: d=√(x-x1)^2+(y-y1)^2
distance of PR: √(-2+2)^2+(9+3)^2= 12
distance of QR: √(7+2)^2+(-3+3)^2=9
distance of PQ: √(7+2)^2+(-3-9)^2= 15
Perimeter: 12+9+15=36
Answer:
Step-by-step explanation:
Since we know that Ivan finished all his science problems (3) we know that there are only math problems remaining
substract the science problems from the total 43-3=40
And now we can determine the amount of math problems
4/5 = 40/x where x is the total amount of math problems Ivan was assigned
cross multiply
4x = 5*40
4x=200
isolate the variable
4x/4 = 200/4
x=50
So Ivan was assigned a total of 50 math problems
(Note*) since there are 40 math problems finished 40/50 is equal to 4/5. Just a tip if you don't want to do the whole calculation
Hope this helps!
