Answer:

0.15 miles per minute

Step-by-step explanation:

You want the rate 4.5 miles in 30 minutes expressed in terms of miles per minute.

To find miles per minute, divide miles by minutes.

speed = miles/minutes = (4.5 mi)/(30 min) = 0.15 mi/min

Samantha can walk 0.15 miles per minute.

The weight of water is 62 1/2 per cubic feet. Water that weighs 325 lbs will fill how many cubic feet

yulyashka [42]

Water that weighs 325 lbs will fill 5.2 cubic feet.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. The weight of water for 1 cubic feet is 62.5

2. The weight of water for 'X' cubic feet is 325

3. To find x, form an equation:

Cubic feet : Weight of water

1 : 62.5

X : 325

4. Cross multiply

X x 62.5 = 1 x 325

62.5X = 325

5. Make X the subject

X = $\frac{325}{62.5}$

6. Solve to find X

X = 5.2 cubic feet

Therefore, water that weighs 325 lbs will fill 5.2 cubic feet.

The circle below is centred at point (2,-1) and has a radius of length 3 what is its equation ?

NeTakaya

Answer:

Option C

Step-by-step explanation:

The standard form of equation of a cirle is:

(x-h)^2+ (y-k)^2=r^2

In the given question as the point is given and the radius of circle is given:

So,

(h,k)=(2,-1)

and

r=3

Here,

h=2

k= -1

Putting the values of h,k and r in standard form

(x-2)^2+ (y-(-1))^2=(3)^2

(x-2)^2+ (y+1)^2=(3)^2

So the equation of circle is:

(x-2)^2+ (y+1)^2=9(3)^2

Option C is the correct answer ..
