A box containing a total of 179 copies of two different paperback books was shipped to marci’s school. The total weight of the books was 128 pounds. If the weight of each of the first paperbacks was two-thirds of a pound and the weight of each of the second paperbacks was three-fourths of a pound, which statements are true? check all that apply. The system of equations is x + y = 179 and two-thirds x + three-fourths y = 128. The system of equations is x + y = 128 and two-thirds x + three-fourths y = 179. To eliminate the x-variable from the equations, you can multiply the equation with the fractions by 3 and leave the other equation as it is. To eliminate the y-variable from the equations, you can multiply the equation with the fractions by –4 and multiply the other equation by 3. There are 104 copies of one book and 24 copies of the other. There are 93 copies of one book and 35 copies of the other. There are 104 copies of one book and 75 copies of the other. There are 93 copies of one book and 86 copies of the other.
The system of equation to represent the situation is
x + y = 179
2/3x + 3/4y = 128
How to solve simultaneous equationTotal copies = 179Total weight = 128 poundslet,
weight of first paperbacks, x = 2/3 pounds
weight of second paperbacks, y = 3/4 pounds
x + y = 179 (1)
2/3x + 3/4y = 128 (2)
multiply (1) by 3 and (2) by -43x + 3y = 537
-4(2/3x) + -4(3/4y) = -512
3x + 3y = 537
-8/3x - 3y = -512
Add both equations to eliminate y3x + (-8/3x) = 537 + (-512)
3x - 8/3x = 537 - 512
(9-8)/3x = 25
1/3x = 25
x = 25 ÷ 1/3
x = 25 × 3
x = 75
Substitute x = 25 into (1)x + y = 179
75 + y = 179
y = 179 - 75
y = 104
The system of equations is x + y = 179 and two-thirds x + three-fourths y = 128.

The velocity v(t) of a particle as a function of time is given by v(t) = (2. 3 m/s) + (4. 1 m/s2)t - (6. 2 m/s3)t2. What is the average acceleration of the particle between t = 1. 0 s and t = 2. 0 s?.
By definition of average acceleration, the ave. acc. for this particle between 1.0 s and 2.0 s is
[tex]a_{\mathrm{ave}[1.0\,\mathrm s,2.0\,\mathrm s]} = \dfrac{v(2.0\,\mathrm s) - v(1.0\,\mathrm s)}{2.0\,\mathrm s - 1.0\,\mathrm s}[/tex]
At the endpoints of the the interval, we have
[tex]v(2.0\,\mathrm s) = 2.3\dfrac{\rm m}{\rm s}+\left(4.1\dfrac{\rm m}{\mathrm s^2}\right)(2.0\,\mathrm s)-\left(6.2\dfrac{\rm m}{\mathrm s^3}\right)(2.0\,\mathrm s)^2 = -14.3\dfrac{\rm m}{\rm s}[/tex]
[tex]v(1.0\,\mathrm s) = 2.3\dfrac{\rm m}{\rm s}+\left(4.1\dfrac{\rm m}{\mathrm s^2}\right)(1.0\,\mathrm s)-\left(6.2\dfrac{\rm m}{\mathrm s^3}\right)(1.0\,\mathrm s)^2 = 0.2\dfrac{\rm m}{\rm s}[/tex]
Then the average acceleration is
[tex]a_{\mathrm{ave}[1.0\,\mathrm s,2.0\,\mathrm s]} = \dfrac{-14.3\frac{\rm m}{\rm s}-0.2\frac{\rm m}{\rm s}}{1.0\,\mathrm s} = \boxed{-14.5\dfrac{\rm m}{\mathrm s^2}}[/tex]

Which term do scientists not use to identify a physical component of the biosphere?.
Answer:
hemisphere
Explanation:
The biosphere is the layer and zone in which all life is on the Earth’s surface. It is organized out of living things and elements that provide the life resources.
The hydrosphere is the mass of water that exists on the earth, obviously providing organisms the resource of drinking water necessary for survival.
The lithosphere is the earth's surface of the planet, the one on which we live. As such, it provides us a solid surface to make settlements and shelters, as well as to plant the food.
The atmosphere is the layer of gases around the earth. Oxygen which organisms breathe exists in this sphere.
Hemisphere is the only term that does not refer to the factor necessary for the organisms’ survival. It is the term that defines the half of the sphere, usually referring to the part of the planet Erath (like the northern Hemisphere – the half of the planet which is on the north).

Use what you know about reflections of functions to match the graph to the function rule. Y = 3x y = 3−x y = −3x.
Answer:
y = 3x
✔ b
y = 3−x
✔ a
y = −3x
✔ c
Explanation:
The graph that matches the function y = 3x is the graph that passes through the origin (0, 0) and increases as you move to the right, forming a diagonal line with a slope of 3.
What is reflections of functions?A function reflection is a transformation that involves flipping the function's graph across a line.
The x-axis, y-axis, or a vertical/horizontal line is usually the line of reflection. The orientation and shape of the original function can be altered by reflections.
A reflection across the x-axis is achieved by vertically flipping a function graph. If the function is f(x), then its reflection across the x-axis is -f(x).
This is because when you reflect across the x-axis, the function's y-coordinates are negated while the x-coordinates remain unchanged.
The graph of y = -3x is a reflection of y = 3x across the x-axis.
The graph of y = 3 - x is a reflection of y = 3x across the line y = x.
Thus, the graph that corresponds to the function y = 3x is the one that passes through the origin (0, 0) and increases to the right, forming a diagonal line with a slope of 3.

Satya, nina, and iana each have a 3/4 chance of going to café georgia for an afternoon coffee at 1:00pm. Bohan will only go to café georgia for a coffee if at least one of his friends is at the café. What is the probability that bohan goes to café georgia for a coffee today?.
Using the binomial distribution, it is found that there is a 0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.
For each friend, there are only two possible outcomes, either they go to the cafe, or they do not. The probability of a friend going to the cafe is independent of any other friend, hence, the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are 3 friends, hence n = 3.They all go to the cafe with a 3/4 probability, hence p = 3/4 = 0.75.The probability at least one goes is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{3,0}.(0.75)^{0}.(0.25)^{3} = 0.0156[/tex]
Then:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0156 = 0.9844[/tex]
0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.
