If the mass of your roommate is 150 lbm, what is his or her weight (lbf)?
Sav [38]

Answer: <em>Weight(lbf) = 4830</em>

Step-by-step explanation:

Given :

Mass of the roommate = 150 lbm

Since we know that g = 32.2 feet/s^{2}

Therefore, we can calculate his/her weight in lbf using the following formula:

Weight(lbf) = Mass × g

Weight(lbf) = 150 × 32.2

<em>Weight(lbf) = 4830</em>

If someone can tell me the answer and how they got it that would be great
sergiy2304 [10]

Answer:

A

Step-by-step explanation: You have two variables, the time and the number of cartons. If time wasn't a variable here, the number of cartons would remain static. You need time, otherwise there would be no change. Now that you know there are two variables, the last two choices must not be correct. Between A and B, the difference is that A says every dip is a purchase and B says every horizontal line is a purchase. Obviously, a horizontal line doesn't mean a purchase; it means the time gone WITHOUT  a purchase. This leaves you with A.

which of the following best describes the technique used to graph the equation using the slope and y-intercept ? Y=5x+10
Vinvika [58]
The slope-intercept is y = mx+b. You can use this as a technique for graphing to make the experience easier. The "5" would be the slope or rise/run of the line. The 10 would be where it started on the y-intercept. You could also say it would be (0,10). Since the slope is positive than it would be going in an upward direction. That is why this technique is good for graphing. I hope this helps you and please put me as the brainliest answer. :)

STALIN [3.7K]

Answer:

-5≤x <1

Step-by-step explanation:

sqrt( x+5) / sqrt(1-x)

The numerator must be greater than zero since it is a square root

sqrt(x+5) ≥0

Square each side

x+5≥0

x≥-5

The denominator must be greater than zero (the denominator cannot be zero)

sqrt(1-x)> 0

Square each side

1-x > 0

1>x

Putting these together

-5≤x <1
