A mountain climber climb 15840 feet on her way to the summit of a mountain how many miles did she climb?

1 answer:

8 0

Hi there!

One mile is equal to 5280 feet. To figure out how many miles the mountain climber climbed, all we need to do is to divide 15840 by 5280. Doing this give us 3 miles.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Theory - Roots of a product
3.1    A product of several terms equals zero.    When a product of two or more terms equals zero, then at least one of the terms must be zero.    We shall now solve each term = 0 separately    In other words, we are going to solve as many equations as there are terms in the product    Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2      Solve  :    -7n = 0    Multiply both sides of the equation by (-1) : 7n = 0

Divide both sides of the equation by 7:
                     n = 0
Solving a Single Variable Equation:
3.3      Solve  :    n-7 = 0    Add 7 to both sides of the equation :                        n = 7

This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️

The radius of a cone is decreasing at a constant rate of 7 inches per second, and the volume is decreasing at a rate of 948 cubi

inessss [21]

Answer:

The height of cone is decreasing at a rate of 0.085131 inch per second.

Step-by-step explanation:

We are given the following information in the question:

The radius of a cone is decreasing at a constant rate.

$\displaystyle\frac{dr}{dt} = -7\text{ inch per second}$

The volume is decreasing at a constant rate.

$\displaystyle\frac{dV}{dt} = -948\text{ cubic inch per second}$

Instant radius = 99 inch

Instant Volume = 525 cubic inches

We have to find the rate of change of height with respect to time.

Volume of cone =

$V = \displaystyle\frac{1}{3}\pi r^2 h$

Instant volume =

$525 = \displaystyle\frac{1}{3}\pi r^2h = \frac{1}{3}\pi (99)^2h\\\\\text{Instant heigth} = h = \frac{525\times 3}{\pi(99)^2}$

Differentiating with respect to t,

$\displaystyle\frac{dV}{dt} = \frac{1}{3}\pi \bigg(2r\frac{dr}{dt}h + r^2\frac{dh}{dt}\bigg)$

Putting all the values, we get,

$\displaystyle\frac{dV}{dt} = \frac{1}{3}\pi \bigg(2r\frac{dr}{dt}h + r^2\frac{dh}{dt}\bigg)\\\\-948 = \frac{1}{3}\pi\bigg(2(99)(-7)(\frac{525\times 3}{\pi(99)^2}) + (99)(99)\frac{dh}{dt}\bigg)\\\\\frac{-948\times 3}{\pi} + \frac{2\times 7\times 525\times 3}{99\times \pi} = (99)^2\frac{dh}{dt}\\\\\frac{1}{(99)^2}\bigg(\frac{-948\times 3}{\pi} + \frac{2\times 7\times 525\times 3}{99\times \pi}\bigg) = \frac{dh}{dt}\\\\\frac{dh}{dt} = -0.085131$

Thus, the height of cone is decreasing at a rate of 0.085131 inch per second.
