a bus is traveling at a constant speed. if the bus travels 15 1/2 miles in 1/3 of an hour how many miles will the bus travel in

Andrei [34K]

Answer:

46 1/2 miles

Step-by-step explanation:

Given:

Distance = 15 1/2 miles

Time = 1/3 hour

Distance =?

Time = 1 hour

Distance : time

15 1/2 miles : 1/3 hour = ? miles : 1 hour

31/2 miles ÷ 1/3 bout = x miles / 1 hour

31/2 × 3/1 = x / 1

93 /2 = x

x = 93/2 miles

= 46 1/2 miles

Therefore, the bus will travel 46 1/2 miles in an hour

Write the equation of a circle for which the endpoints of a diameter are (-2,-2) and (4,-10)

Maurinko [17]

Answer:

Therefore the required Equation of Circle

$x^{2}+y^{2}-2x+12y+12=0$

Step-by-step explanation:

Given:

End point of Diameter be

point A( x₁ , y₁) ≡ ( -2 ,-2 )

point B( x₂ , y₂) ≡ ( 4 , -10 )

To Find:

Equation of a circle =?

Solution:

When end points of the Diameter are A( x₁ , y₁) , B( x₂ , y₂). then the Equation of Circle is given as

$(x-x_{1})(x-x_{2})+(y-y_{1})(y-y_{2})=0$

Substituting the end point are

$(x-(-2))(x-4)+(y-(-2))(y-(-10))=0\\(x+2))(x-4)+(y+2))(y+10))=0\\$

Applying Distributive Property we get

$x^{2} -2x-8+y^{2}+12y+20 =0\\\\x^{2}+y^{2}-2x+12y+12=0$

Therefore the required Equation of Circle

$x^{2}+y^{2}-2x+12y+12=0$
