Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92
Answer: 480 minutes or 8 hours
Step-by-step explanation:
24,000 ÷ 50 = 480.
It will take 480 minutes to fill the pool.
480 minutes ÷ 60 is also 8. So it will take 8 hours to fill the pool, or 480 minutes. Whichever one you want to use.
Hope this helps!
Answer:
The third one
Step-by-step explanation:
Slope is rise/run
This graphs shows the line going up by 2 and to the right 3
Answer: (C) r² = (x+5)²+(y-4)²
Solution:-
The given endpoints are (-7,1) and (-3,7)
so the center will be at the mid point of the line connecting these two points.
hence, center ={ (-7+-3)/2, (1+7)/2 }
hence, C= (-5,4)
so, the equation of the circle is:-
⇒ (x-(-5))²+(y-4)²=r²
or, (x+5)²+(y-4)²=r²
