Answer:
124
Step-by-step explanation:
because any circle is 360 degrees so you add 109+84+43 and that is equal to 236 then to find angle EOF you subtract 236-360=124
need a better explanation just ask me
X^2-(2)(x)(4)+16-7=0
x^2-(2)(x)(4)+4^2 =7
(x-4)^2=7
So value of p is 4 and q is 7
Answer:
It will take 25.7 minutes when they are working together
Step-by-step explanation:
Here, we want to know how long it will take both pipe working together to drain the tank
Let the volume of water to be drained be xL
for the first one, rate is
x/45 L/minutes
for the second x/60 L/minutes
Joint rate will be
x/45 + x/60 = 4x + 3x/180 = 7x/180
Now go get the time involved here, we simply divide the volume by the rate
That would be;
x divided by 7x/180
= x * 180/7x
= 180/7 = 25.7 minutes
