a person who weighs 120 lb on Earth would weigh 45 1/5 pounds on Mars set up a proportion to determine how much a 90 pound perso

Lunna [17]

Weight on Mars for a 90lb person: 34.05lbs

Weight on Mars : Weight On Earth/91.8m/s^2 • 3.711m/s

Earths Force : 91.8m/s^2

Mars Gravitational Force : 3.711m/s

So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. A person is about 62.17% heavier on earth than on Mars.

How to solve this?? (r^-7b^-8) ^0 ------------- (t^-4w)

professor190 [17]

keeping in mind that anything raised at the 0 power, is 1, with the sole exception of 0 itself.

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{(r^{-7}b^{-8})^0}{t^{-4}w}\implies \cfrac{1}{t^{-4}w}\implies \cfrac{1}{t^{-4}}\cdot \cfrac{1}{w}\implies t^4\cdot \cfrac{1}{w}\implies \cfrac{t^4}{w}$

PLEASE someone help its due tonight im almost done

<h3>Answers:</h3>

48 seconds
3624 feet

========================================================

Explanation:

x = number of seconds that elapse

y = altitude (aka height) of the plane

The equation for plane A is

y = 20.25x+2652

because it starts off at 2652 ft in the air, and then adds on 20.25 feet per second which is what the 20.25x describes

The equation for plane B is

y = 75.5x

The y intercept is zero because plane B starts on the ground, aka height 0.

------------------

The system of equations is

$\begin{cases}y = 20.25x+2652\\y = 75.5x\end{cases}$

If we want to know when they'll reach the same height (y), then we can set the two right hand sides equal to each other and solve for x.

75.5x = 20.25x+2652

75.5x-20.25x = 2652

55.25x = 2652

x = (2652)/(55.25)

x = 48

The two planes reach the same altitude at exactly 48 seconds

That altitude is 3624 feet because

y = 20.25*x + 2652 = 20.25*48+2652 = 3624
y = 75.5*x = 75.5*48 = 3624

Notice I plugged x = 48 into each equation and I got the same y value of y = 3624. This helps confirm the answers.

Convert 95 lbs to grams

VashaNatasha [74]

Answer:

43091.3 or 43181.81(81 repeated)

Step-by-step explanation:

There are two answers because it depends on the method you use. You can get the second answer by plugging 95 into the equation gram*0.0022=pound or gram=(pound/0.0022). When you insert the 95, you get 43181.81(81 repeated).You can find the first answer by just looking it up on the conversion chart on google.
