Answer:

M = 4E OR 1/4 OR 1:4

Step-by-step explanation:

If melenie has 1 hair tie for every 4 or elena's hairties, then we can use M for Melenie and E for Elena and we get the ratio m=4e OR in fraction form 1/4

A car produces 53.9 tons of carbon dioxide over a 7 year period. Find its carbon footprint (tons of carbon dioxide per year).

Marina86 [1]

Answer:

carbon footprint

7.7 tons

Step-by-step explanation:

Given that,

carbon dioxide produced by a car over 7 year period = 53.5 tons

To find,

carbon footprint <em>(tons of carbon dioxide per year)</em>

7 years ------> 53.5 tons

1 year -------> 53.9/7 tons

= 7.7 tons

tons of carbon dioxide produced per year = 7.7

at 111111:55\text{ p.m.}55 p.m.55, start text, space, p, point, m, point, end text, thomas ties a weight to the minute hand of a

Ahat [919]

The trigonometric function's formula, which simulates the torque (tau) that the weight applied t minutes after Thomas attached it is

$3 Sin (\frac{2\frac{22}{7} }{60} (t-51))$

The angular speed of the minutes hand is

$w = \frac{2 (\frac{22}{7}) }{60}$ rad/min

Following the application of weight, the torque as a function of time t is,

$t= t_{0} sin (w (t-5) min)\\ = (3 Nm) sin ((\frac{2 (\frac{22}{7} }{60} ) rad/min (t-5) min)$

$= (3 Nm) sin ( \frac{2 (\frac{22}{7} }{60} (t-5) rad ) \\= 3 sin (\frac{2 \frac{22}{7} }{60} (t-5)$

<h3>What is torque ?</h3>

Torque, which is also known as the moment of a force, is the propensity of a force to rotate the body to which it is applied. Force (F) x Distance (r) = Torque is how torque is calculated. The distance (r) between the pivot point and the force's action point. A vector quantity is a torque. As a vector quantity, torque always has a direction that is perpendicular to the plane that contains the vectors of force and displacement.
