Answer:
all sides probably. ( I think )
Answer:
180 minutes
Step-by-step explanation:
Starting with the distance formula ...
d = rt
dividing by the coefficient of t will give an equation for t:
t = d/r
Ryan's rate of 4 miles per hour can be expressed in minutes as 4 miles per 60 minutes. The Ryan's time is ...
t = (12 mi)/(4 mi/60 min) = 12·60/4 min = 180 min
Ryan's time is 180 minutes.

Answer:
x=2, x=-8 : 2 will be taken as the answer as negative is discarded so C is the answer
Step-by-step explanation:
Apply Log Rules:
x(x+6)=16
Solve:
x=2, x=-8
Answer:
D) The circle is centred at (-8,3) and has a diameter 20
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the circle
( x + 8)² +( y-3)² = 100
⇒ ( x + 8)² +( y-3)² = 10²
Standard form of the circle ( x-h)² +(y-k)² = r²
Centre of the circle (h , k) = (-8 , 3)
Radius of the circle r = 10
Diameter of the circle 'd' = 2r = 2(10) =20
<u><em>Final answer:-</em></u>
The circle is centred at (-8,3) and has a diameter 20
Answer: u=7
Step-by-step explanation:
-6= -2u+4(u-5)
-6= -2u+4u-20
-6= 2u-20
14= 2u
7=u
