Answer:
the answer is A
Step-by-step explanation:
Final answer:
The answer is approximately 2.61x10⁹ cans recycled in 16 days, which is option (a).
Explanation:
The student is asking about a mathematical estimation of how many aluminum cans are recycled over a 16-day period, given an average rate of recycling per minute.
To find the answer, we'll first calculate the number of minutes in 16 days:
16 days × 24 hours/day × 60 minutes/hour = 23,040 minutes.
Now, we multiply this by the average number of cans recycled per minute:
23,040 minutes × 113,204 cans/minute = 2.61x10⁹ cans.
Expressing this value in scientific notation gives us:
About 2.61x10⁹ aluminum cans recycled in 16 days, which corresponds to option (a) in the multiple-choice provided by the student.
A triangle has side length of 14 cm 48 cm and 50 cm classify it as acute obtuse or right
The triangle with side lengths of 14 cm, 48 cm, and 50 cm is a right triangle.
Explanation:The lengths of the sides of the triangle are 14 cm, 48 cm, and 50 cm. To classify the triangle, we need to determine if it is acute, obtuse, or right.
Using the Pythagorean theorem, we can check if it satisfies the condition for a right triangle. If the square of the length of the longest side (50 cm) is equal to the sum of the squares of the other two sides (14 cm and 48 cm), then it is a right triangle.
In this case, (50)^2 = (14)^2 + (48)^2, which is true. Therefore, the triangle is a right triangle.
Final answer:
A triangle with side lengths of 14 cm, 48 cm, and 50 cm is classified as an acute triangle.
Explanation:
A triangle with side lengths of 14 cm, 48 cm, and 50 cm can be classified as an acute triangle.
To determine this, we need to check if the square of the longest side (50 cm) is less than the sum of the squares of the other two sides (14 cm and 48 cm).
502 < 142 + 482
2500 < 196 + 2304
2500 < 2500
This inequality is not true, so the triangle is not obtuse or right. Thus, it is classified as an acute triangle.

2n^2+3n-9 factoring trinomials
The trinomial [tex]2n^2[/tex]+3n-9 cannot be factored using integers as no two numbers exist that multiply to give -18 (the product of the leading coefficient and the constant term) and add up to 3 (the middle coefficient).
To factor the quadratic trinomial [tex]2n^2[/tex]+3n-9, one must find two binomials that, when multiplied together, give the original trinomial. Factoring complex trinomials can sometimes be achieved by finding two numbers that multiply to give the product of the leading coefficient (2 in this case) and the constant term (-9 in this case), and add to give the middle coefficient (3 in this case). However, for this particular trinomial, such numbers do not exist, and it cannot be factored using integers. This means that either the trinomial is prime (cannot be factored), or it would require the quadratic formula to solve for factors involving irrational or complex numbers.
Solve the system by substitution.

3. Brinn’s rectangular kitchen has an area of 81 square feet. The kitchen is 9 times as many square feet as Brinn’s pantry. If the rectangular pantry is 3 feet wide, what is the length of the pantry?
The length of the pantry is 3 feet.
To find the length of the pantry, we need to determine its area first. According to the question, the kitchen is 9 times the size of the pantry. With the kitchen's area being 81 square feet, the pantry's area would be 81 square feet divided by 9, which equals 9 square feet. Since we are given that the width of the pantry is 3 feet, we divide the total area of the pantry by its width to find the length.
The calculation is as follows:
Area of kitchen: 81 sq ft
Area of pantry: 81 sq ft / 9 = 9 sq ft
Width of pantry: 3 ft
Length of pantry: Area of pantry / Width of pantry = 9 sq ft / 3 ft = 3 feet long.
In 2000 Michigan had a population of 9,938,444. The number of people living in Michigan decreased by 0.6% in 2010. What was Michigan’s approximate population in 2010?
Answer:
9,878,813
Step-by-step explanation:
First, make 0.6% into a decimal
0.6 / 100 = 0.006
Then, multiply the number of people living in Michigan in 2000 by the number of people decreased (the percentage decrease) in 2010
9,938,444 x 0.006 = 59630.664
Last, subtract the percentage decrease by the original population in 2000
9,938,444 – 59630.664 = 9,878,813
In 2010 the approximate population in Michigan was about 9,878,813 (to the nearest whole person)

Show that the point (7/25, 24/25) is on the unit circle
To show that the point (7/25, 24/25) is on the unit circle, we need to demonstrate that its distance from the origin is equal to 1.
Explanation:To show that the point (7/25, 24/25) is on the unit circle, we need to demonstrate that its distance from the origin is equal to 1.
The distance between two points, (x1, y1) and (x2, y2), is given by the formula: √((x2-x1)² + (y2-y1)²).
In this case, the distance between the point (7/25, 24/25) and the origin (0, 0) can be calculated as: √((7/25-0)² + (24/25-0)²) = √((49/625) + (576/625)) = √(625/625) = 1.
Since the distance between the given point and the origin is indeed equal to 1, we can conclude that the point is on the unit circle.

find the zero of the function. state the multiple zero . y=9x^3 -9x
The zeros of the function y = 9x³ - 9x are x = 0, x = 1, and x = -1. There are no multiple zeros for this function.
The question seeks to identify the zeros of the function y = 9x^3 - 9x. To find the zeros, we set the function equal to zero and solve for x.
Step 1: Set the function equal to 0: 0 = 9x³ - 9x.Step 2: Factor out a common term: 0 = 9x(x² - 1).Step 3: Factor further using difference of squares: 0 = 9x(x - 1)(x + 1).Step 4: Set each factor equal to zero: x = 0, x = 1, x = -1.Step 5: Identify the multiple zero, if any. In this case, there are no multiple zeros.The zeros of the function are x = 0, x = 1, and x = -1.
Therefore, as per the above explaination, the correct answer is x = 0, x = 1, and x = -1.

Find the area of a regular hexagon with the given measurement.
2 sqrt3 apothem
A =
...?
Answer:
41.57 unit²
Step-by-step explanation:
We know,
Area of a regular hexagon = [tex]3\times (sidelength)\times (apothem)[/tex].
The length of the apothem = [tex]2\sqrt{3}[/tex] units.
Since, we know, 'a regular hexagon splits into 6 identical equilateral triangles'.
As, the apothem of the regular hexagon = height of the equilateral triangle
So, height of the equilateral triangle = [tex]2\sqrt{3}[/tex] units.
As, in the equilateral triangle, 'One of the side length is the S, other will be [tex]\frac{S}{2}[/tex] and height is [tex]2\sqrt{3}[/tex] units'.
So, using Pythagoras Theorem, we have,
[tex]hypotenuse^{2}=perpendicular^{2}+base^{2}[/tex]
i.e. [tex]S^{2}=(\frac{S}{2})^{2}+(2\sqrt{3})^{2}[/tex]
i.e. [tex]S^{2}=\frac{S^2}{4}+12[/tex]
i.e. [tex]S^{2}-\frac{S^2}{4}=12[/tex]
i.e. [tex]\frac{3S^2}{4}=12[/tex]
i.e. [tex3S^2=48[/tex]
i.e. [texS^2=16[/tex]
i.e. S= 4 units
That is, the side length of the hexagon = 4 units.
Thus, the area of the hexagon is given by,
Area of a regular hexagon = [tex]3\times (4)\times (2sqrt{3})[/tex]
i.e. Area of a regular hexagon = [tex]12\times (2sqrt{3})[/tex]
i.e. Area of a regular hexagon = [tex]24sqrt{3}[/tex]
i.e. Area of a regular hexagon = 41.57 unit²
Hence, the area of the regular hexagon is 41.57 unit².

The converse statement interchange the hypothesis and the conclusion.
The converse of x=9 then [tex]x^{2} =81.[/tex] is [tex]x^{2} = 81 then x=9.[/tex] is true.
A biconditional statement is defined to be true whenever both parts have the same truth value . combining the statements as a biconditional we have
If [tex]x^{2}[/tex]. = 81, then x = 9.
x = 9 if and only if [tex]x^{2} .[/tex] = 81

cell phone company A charges $20 per month plus $0.05 per text message. Cell phone company B charges $10 per month plus $0.07 per text message. Is there any number of text messages that will result in the exact same charge from both companies?
Answer : The number of text messages that will result in the exact same charge from both companies is, 500
Step-by-step explanation :
Let the number of text messages be, 'x'
Cell phone company A charges $20 per month plus $0.05 per text message. Thus, the equation will be:
[tex]20+0.05x=0[/tex] ............(1)
Cell phone company B charges $10 per month plus $0.07 per text message. Thus, the equation will be:
[tex]10+0.07x=0[/tex] ............(2)
Now equating equation 1 and 2, we get:
[tex]20+0.05x=10+0.07x[/tex]
[tex]20-10=0.07x-0.05x[/tex]
[tex]10=0.02x[/tex]
[tex]x=\frac{10}{0.02}[/tex]
[tex]x=500[/tex]
Thus, the number of text messages that will result in the exact same charge from both companies is, 500
