Answer:

13 m

Step-by-step explanation:

The ladder forms a right triangle with the wall that has legs of 5 and 12. We need to solve for the length of the ladder, which in this case, is the hypotenuse of the right triangle. You could use the Pythagorean Theorem but there's an easier way to do this. We can use the 5 - 12 - 13 Pythagorean triple so we know that the length of the ladder is 13 m.

Kenji packed an exercise ball into a cylindrical package . How much space does the package occupy in terms of pi . Enter your an

grandymaker [24]

Answer:

The space that the package would occupy is 45 $\pi$ cubic feet.

Step-by-step explanation:

The space that the package occupies is the volume of the cylinder. The volume of an object is the 3 dimensional capacity of the object.

Volume of a cylinder = $\pi$ $r^{2}$ h

where: r is the radius and h is the height of the cylinder.

Given that; h = 5 feet and r = 3 feet.

The required volume = $\pi$ × $(3)^{2}$ × 5

= $\pi$ × 9 × 5

= 45 $\pi$ cubic feet

The space that the package would occupy is 45 $\pi$ cubic feet.

I need the answer and if you would please explain step by step

emmasim [6.3K]

Answer:

x=17

Step-by-step explanation:

well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17

$3x + 10 = 61 \\ 3x = 51 \\ x = 17$
