Alfonso leans a 20 ft ladder long against the wall with a base of 6 feet from the wall. How far up the wall does the ladder reac

jolli1 [7]

Answer:

19.1 ft

Step-by-step explanation:

-This a Pythagorean theorem problem given by the function:

$b^2+h^2=H^2$

Where

H is the Hypotenuse length

h is the perpendicular height

b is the base length.

#Given that H=20 ft and base length,b =6 ft, the perpendicular height is calculated as:

$h^2+b^2=H^2\\\\h^2=H^2-b^2\\\\h^2=20^2-6^2=364\\\\h=\sqrt{364}\\\\=19.0788\approx 19.08\ ft$ $\approx 19.1 \ ft$

Hence, the ladder reaches the wall at a height of 19.1 ft

A composite figure is formed from a cone and a cylinder with the same base radius, and its volume can be calculated by multiplyi

olga55 [171]

The composite figure comprises of a cone balanced on top of cylinder

Step-by-step explanation:

The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r

Then the volume of the cone will be $V_{cone}$

Then the volume of the cylinder will be $V_{cylinder}$

$V_{cylinder} = \pi r^{2} h_{cylinder}$

The total volume of the composite figure will be V, where

$V= V_{cone} + V_{cylinder}$

$V = \frac{1}{3} \pi r^{2} h_{cone} +\pi r^{2} h_{cylinder}$

let the height of cone and cylinder be same

The volume of the composite figure will be $\frac{4}{3} \pi r$ $r^{2} h$

Hence $\frac{4}{3} = \frac{a}{b}$

Thecomposite figure comprises of a cone balanced on top of cylinder

a worker at a mill is delivering 5lbs bags of flour to a local warehouse, each box holds 12 bags. If the warehouse orders 3 tons

ivolga24 [154]

I'm pretty sure that u multiply 12 and 5 and u get 60 and that's in only one box just 60lbs then u find how many pounds in a ton which is 2,000 then u have 3 tons so multiple 2,000 and 3 and u get 6,000 so then u divide 60 and 6,000 and u get 100 I'm pretty sure that's how u do it
