AleksandrR [38]
Oooh! I love this kind of math, so easy to do!

Like I say ALL the time, if you know how to solve percentages you know how to solve anything that deals with percentages. If you don't izz all gucci! :D

To solve a percentage make it a decimal & multiply. :) (SIMPLE)
- .300 % multiplied by 1000 = 300 :D you would pay 300$ a year obviously! 

I'm not that great at percentage math, although it is fairly easy. I hope you can use this information too push you closer too the answer! Good Luck! <3

The surface area of a given cone is 1,885.7143 square inches. What is the slang height?
kap26 [50]

Answer:

If r >> h, the slang height of the cone is approximately 23.521 inches.

Step-by-step explanation:

The surface area of a cone (A) is given by this formula:

A = \pi \cdot r^{2} + 2\pi\cdot s

Where:

r - Base radius of the cone, measured in inches.

s - Slant height, measured in inches.

In addition, the slant height is calculated by means of the Pythagorean Theorem:

s = \sqrt{r^{2}+h^{2}}

Where h is the altitude of the cone, measured in inches. If r >> h, then:

s \approx r

And:

A = \pi\cdot r^{2} +2\pi\cdot r

Given that A = 1885.7143\,in^{2}, the following second-order polynomial is obtained:

\pi \cdot r^{2} + 2\pi \cdot r -1885.7143\,in^{2}  = 0

Roots can be found by the Quadratic Formula:

r_{1,2} = \frac{-2\pi \pm \sqrt{4\pi^{2}-4\pi\cdot (-1885.7143)}}{2\pi}

r_{1,2} \approx -1\,in \pm 24.521\,in

r_{1} \approx 23.521\,in \,\wedge\,r_{2}\approx -25.521\,in

As radius is a positive unit, the first root is the only solution that is physically reasonable. Hence, the slang height of the cone is approximately 23.521 inches.

Matthew 60% + Luke 40%= Profit 100%


if profit is $25; 60% will be: 0.60* $25=$15 ; Matthew's share
