If a wheel with a radius of 80 inches spins at a rate of 50 revolutions per minute, find the approximate linear velocity in mile

Lubov Fominskaja [6]

$\bf \textit{arc's length}\\\\
s=rw\qquad 
\begin{cases}
r=radius\\
w=\textit{angular speed}
\end{cases}\qquad w=\cfrac{50 rev}{min}\cdot \cfrac{2\pi }{rev}
\\\\\\
w=\cfrac{100\pi }{min}\qquad s=80in\cdot \cfrac{100\pi }{min}\implies s=\cfrac{8000\pi\ in}{min}\\\\
-------------------------------\\\\
\textit{now to convert it to miles/hr}
\\\\\\
\cfrac{8000\pi\ in}{min}\cdot \cfrac{ft}{12in}\cdot \cfrac{mile}{5280ft}\cdot \cfrac{60min}{hr}\implies \cfrac{8000\pi \cdot 60\ in}{12\cdot 5280\ hr}$

Which sentence best describes the independent and dependent variables in the following problem? The parking garage charges $3 fo

alexandr402 [8]

Ok so the dependent variable would be $1.45 for each addition hour. The cost depends on every hour so u can't really calculate it unless u have the hours.
$3 is independent since it's only charged on the first hour. It doesn't rely on any other information.

What is the working out for 5x+3=2x+15

Nataliya [291]

The solution is x = 4

Step-by-step explanation:

The given equation is a linear equation so it will have only one equation

Given equation is:

$5x+3=2x+15$

Subtraction property of equality:

$5x+3-3 = 2x+15-3\\5x = 2x+12$

Subtraction property of equality:

$5x-2x = 2x-2x+12\\3x = 12$

Division Property of Equality:

$\frac{3x}{3} = \frac{12}{3}\\x = 4$

Hence,

The solution is x = 4

A candy store sells 8-pound bags of mixed hazelnuts and cashews. If c pounds of cashews are in a bag, the price p of the bag can

Butoxors [25]

C= how many pounds of cashews in a bag
P=how much the cost
Solve for C
we know that P would have to be $18.11
Sub wat P= to in the equation
$18.11=2.59c+1.79(8-c)
Start with multiplying
1.79(8)=14.32(c)=14.32c
Then add like terms
2.59c+14.32c=16.91c
Divide to get C by itself. So that 16.91 cancel itself.
16.91c/16.91c=18.11/16.91
C=1.07
