A^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
find the square root of 400
c = 20 miles
It would be 1/4 because there are 12 inches on a ruler. And if it lands between 3 and 5 there are 3 chances out of 12 that it will land between 3 and 5. 3/12 simplifies to 1/4
Sum = 1440°
Each interior angle = 144°
Each exterior angle = 36°
Explanation:
6) Sum of interior angles = 180(n - 2)°
where n = number of sides
For a decagon, the number of sides = 10
The sum of interior angles = 180(10 -2)
The sum of interior angles = 180(8) = 1440°
Each interior angle = The sum of interior angles/ number of sides
Each interior angle = 1440/10 = 144°
Sum of Exterior angles of a polygon = 360°
Each exterior angle = Sum of Exterior angles of a polygon/ number of sides
Each exterior angle = 360/10
Each exterior angle = 36°
Answer:
x=20, y=17, and z=6 or (20,17,6)
Step-by-step explanation:
Hi there!
We're given the system of equations:
2x+z=46
3z=18
2y+z=40
and we need to solve for x, y, and z
first, let's find the value of z, as we have z by itself (no other variables) in 3z=18
divide both sides by z
z=6
the value of z is found :)
now we can use z=6 to find the value of the other variables; for example, plug z as 6 into 2x+z=46 to solve for x
2x+6=46
subtract 6 from both sides
2x=40
divide by 2
x=20
Finally, let's find y
once again, we can substitute z as 6 in the equation 2y+z=40 to find y
2y+6=40
subtract 6 from both sides
2y=34
divide by 2
y=17
so the answer is: x=20, y=17, and z=6; if you need it in a point it's (20,17,6)
Hope this helps! :)
