For instance, the factors<span> of 15 are 3 and 5, because 3×5 = 15. Some </span>numbers<span> have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4. A </span>number<span> that can only be factored as 1 times itself is called "prime".</span>

Answer:

42390 ft³

Step-by-step explanation:

Since the tanks are congruent, they both have same volume.

If you rejoin them, it will form a cylinder with the radius of 15 ft and height of 120 ft.

<u>The volume of the cylinder:</u>

V = πr²h = 3.14*15²*120 = 84780 ft³

<u>The volume of each tank is half the volume of the cylinder:</u>

V(tank) = 84780 / 2 = 42390 ft³

Find the quotient 3 6/7 divided by 5/21

Snezhnost [94]

Answer:

81/5 or 16 1/5.

Step-by-step explanation:

First convert the mixed number to an improper fraction:

3 6/7

= (3*7 + 6) / 7

= 27/7.

So we have

27/7 / 5/21

Invert the second fraction and multiply:

= 27/7 * 21/5

= (27*21) / (7*5)

= (27*3) / 5 ( as 21/7 = 3)

= 81/5

= 16 1/5.

Find the distance between points (2,5) and (-2,2)

mrs_skeptik [129]

Answer:

5

Step-by-step explanation:

Let :

x(1) be 2

y(1) be 5

x(2) be -2

y(2) be 2

We know that distance between any 2 points is equal to:-

$\sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} }$

So using the above formula ,

$\sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} }$

$= > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} }$

$= > \sqrt{16 + 9}$

$= > \sqrt{25} = 5$
