Answer:
145
Step-by-step explanation:
The volume of the rectangular prism bin is area of base * height.
Base/top is a square, so area would be 150 * 150 = 22,500
Thus, volume of bin = 22,500 * 210 = 4,725,000
Using volume of sphere formula and given radius of each ball is 16cm, we can say that
Volume of 1 Ball = [tex]\frac{4}{3}\pi r^3 = \frac{4}{3}\pi (16)^3=17,157.28[/tex]
Since, 190% is including the packing, we can take volume of 1 ball (inclusive of packaging) to be 1.9 * 17,157.28 = 32,598.83
How many of this will fit in the bin, we divide bin volume by this:
Number of Balls = [tex]\frac{4,725,000}{32,598.83}=144.94[/tex]
Rounding, we can say that we can fit 145 balls, 2nd answer choice is right.
Find the area of the trapezoid!!!! PLEASE HELP!!!!
64 ft^2
54✔️3 ft^2
32✔️3 ft^2
48✔️3 ft^2
ANSWER
[tex]32 \sqrt{3} {ft}^{2} [/tex]
EXPLANATION
The area of a tra-pezoid is half times sum of the bases times the vertical height.
From the diagram ( see attachment) we use the Pythagoras Theorem to obtain,
[tex] {x}^{2} + {(4 \sqrt{3}) }^{2} = {8}^{2} [/tex]
[tex] {x}^{2} + 48 = 64[/tex]
[tex]{x}^{2} = 64 - 48[/tex]
[tex]{x}^{2}=16[/tex]
[tex]x = \sqrt{16} = 4ft[/tex]
This implies that , y=10-4=6ft
The area of tra-pezoid
[tex] = \frac{1}{2} (10 + 6) \times 4 \sqrt{3} [/tex]
[tex] = \frac{1}{2} (16) \times 4 \sqrt{3} [/tex]
[tex] = 8\times 4 \sqrt{3} [/tex]
[tex] = 32 \sqrt{3} {ft}^{2} [/tex]

Sarah bought 6 pens that each cost the same price and she also bought a package of paper for$1.25.if her total before tax was $10.19 what was the price of each pen?
If you don’t know the tax price/value then you can’t add that on the total amount. So, if we don’t know the value of that we can just forget about it for now.
You do $10.19-$1.25 (to get just the price of the pens) =$8.94
To get the value of one pen just do $8.94 divided by 6 (the total number of pens)=$1.49
$1.49=Price for one pen
Hope this helps :)
Give some examples of trigonometric functions that generate periodic waves.
Answer:
1. Sine (sin) 2. Cosine (cos) 3. Tangent (tan) 4. Secant (sec) 5. Cosecant (csc) 6. Cotangent (cot) These functions are used to relate the angles of a triangle with the sides of that triangle.
Step-by-step explanation:
Sine and cosine functions are examples of trigonometric functions that generate periodic waves. These waves can be represented in equations like y = A sin(wt + p) and x(t) = A cos(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.
Explanation:Trigonometric functions like the sine, cosine, and tangent functions are often used to generate periodic waves in mathematics and physics. For instance, simple harmonic motion, which is related to alternating cycles in physics, can be represented by sine and cosine functions.
Let's consider the example of a bouncing object on a spring. The object's position over time can be represented by a sine function, resulting in a wave-like pattern on a graph. A sine function generating a periodic wave would look like this: y = A sin(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.
Another example is a cosine function that might represent a phase-shifted wave, like this: x(t) = A cos(wt + p). Again, A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift. This function is effectively identical to the sine function but is shifted to the right on the x-axis.

1. Complementary Angeles
2. Angel1-37
What is angel 4
3
Angel 1-40
What is angel 5
Answer:
1. D ∠4 and ∠5
2. C 37°
3. A 50°
Step-by-step explanation:
1. Complementary angles are those that add up to 90°.
From the diagram you can see that angles 4 and 5 together form right angle, so angles 4 and 5 are complementary.
2. Angles 1 and 4 are vertical angles. Vertical angles have the same measure, so
∠4=∠1=37°
3. From 1,
∠4+∠5=90°
From 2
∠1=∠4
Since ∠1=40°, then ∠4=40°
So,
∠5=90°-40°=50°

find the mode(s) for the given sample data.
the weights (in ounces) of 14 different apples are shown below.
4.9, 4.6, 5.1, 4.2, 4.8, 4.9, 4.6, 4.3, 4.1, 4.2, 4.9, 4.3, 4.2, 5.4
Answer:
4.9 & 4.2
Step-by-step explanation:
First, we will have to define mode,
“Mode is the most frequently occurring value of the given data.”
The value with the greatest frequency is called mode. In order to find mode, we have to skim through the data. The value which is repeated most is the mode of the given data. A data can have more than one modes.
For the above data,
4.9 is repeated 3 times.
4.2 is repeated 3 times.
These both numbers have highest frequency in the data.
So the modes are 4.9 and 4.2 ..
Answer:
So the modes are 4.9 and 4.2
Find three points that solve the equation x-4y=-18
For this case we must find three points that satisfy the following equation:
[tex]x-4y = -18[/tex]
So:
(-14,1)[tex]-14-4 (1) = - 14-4 = -18[/tex]
(10,7)[tex]10-4 (7) = 10-28 = -18[/tex]
(-30, -3)[tex]-30-4 (-3) = - 30 - (- 12) = - 30 + 12 = -18[/tex]
Answer:
Thus, three points that meet the equation are:
(-14,1)
(10,7)
(-30, -3)
Three points that solve the equation x-4y=-18 are (0, 4.5), (-18, 0), and (-14, 1).
To find three points that solve the equation x-4y=-18, we can choose values for one variable and solve for the other. Here are three points that satisfy the given linear equation:
Let x = 0: Substituting into the equation, we get 0 - 4y = -18, which gives y = 4.5. So, one point is (0, 4.5).Let y = 0: Plugging this into the equation yields x - 4(0) = -18, so x = -18. Thus, a second point is (-18, 0).Let y = 1: Substituting y into the equation, we find x - 4(1) = -18, leading to x = -14. Therefore, a third point is (-14, 1).These points are part of the infinite set of solutions to the linear equation x-4y=-18.

Answer:
a) 3x(x+4y-3y^2)
b) 3x(3x -y + 5y^3)
Step-by-step explanation:
a) 3x^2+12xy-9xy^2
We need to factorize the above equation.
We can take 3x common from the above equation.
3x(x+4y-3y^2)
It cannot be further factorized. So the factors are:
3x(x+4y-3y^2)
b) 9x^2 - 3xy +15xy^3
We need to factorize this equation.
Since 3x is common in all terms, taking 3x common
3x(3x -y + 5y^3)
It cannot be further factorized. So the factors are:
3x(3x -y + 5y^3)

A savings account pays an annual rate of 2% simple interest. How much would you need to deposit to earn $100 interest by the end of the 2nd year?
Answer:
You would need to deposit $2500
Step-by-step explanation:
The simple Interest formula is given as;
[tex]I=\frac{P*R*T}{100}[/tex]
Where I is the interest earned, P the principal amount deposited, R the simple interest rate and T the time.
The question requires us to determine the Principal given that;
I = 100
R = 2
T = 2
We make the Principal the subject of the formula;
[tex]P=\frac{100*I}{R*T}\\\\P=\frac{100*100}{2*2}=2500[/tex]

The diagonal of a TV is 28 inches long. Assuming that thia diagonal forma a
pair of 30-60-90 right triangles, what are the exact length and width of the TV?
O
A. 55
inches by 568 inches
O B. 14 inches by 142 inches
O c. 56 inches by 56.5 inches
OD. 14 inches by 14,5 inches
Answer:
Hmm... None of these choices seem to be correct.
Step-by-step explanation:
In 30-60-90 triangles, the length of the shorter leg is half the length of the hypotenuse. In this case, the hypotenuse is the diagonal. So half of 28 is 14. Therefore, the width of the TV is 14 inches. This eliminates answer choices A and C, that would imply the answer is either B or D, but.....In 30-60-90 triangles, the length of the longer leg is [tex]\sqrt{3}[/tex] times the length of the shorter leg. So if we were being exact, the length of the TV is [tex]14\sqrt{3}[/tex] . And if we rounded, the length would be about 24.25. There is no choice in your options that is similar to our conclusions. Maybe you should contact your teacher about this. Have a nice day! :)The exact dimensions of the TV are approximately 14 inches by [tex]14\sqrt{3}[/tex] inches, which simplifies to 14 inches by 142 inches
The correct answer is:
B. 14 inches by 142 inches.
To find the exact length and width of the TV, we can use the properties of a 30-60-90 right triangle. In such a triangle, the side lengths are related as follows: the length of the side opposite the 30-degree angle is [tex]\( \frac{1}{2} \)[/tex] times the length of the hypotenuse, and the length of the side opposite the 60-degree angle is [tex]\( \frac{\sqrt{3}}{2} \)[/tex] times the length of the hypotenuse.
Given that the diagonal of the TV forms the hypotenuse of two 30-60-90 right triangles, let's denote the length and width of the TV as [tex]\( L \)[/tex] and [tex]\( W \)[/tex] respectively, and the length of the diagonal as [tex]\( D \).[/tex]
We have the following equations:
[tex]\[ L = \frac{1}{2}D \][/tex]
[tex]\[ W = \frac{\sqrt{3}}{2}D \][/tex]
Given that the diagonal [tex]\( D = 28 \)[/tex] inches, we can substitute this value into the equations to find the exact length and width:
[tex]\[ L = \frac{1}{2} \times 28 = 14 \text{ inches} \][/tex]
[tex]\[ W = \frac{\sqrt{3}}{2} \times 28 \approx 14\sqrt{3} \text{ inches} \][/tex]
Now, we need to rationalize the denominator for the width:
[tex]\[ W = 14\sqrt{3} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{42}{\sqrt{3}} \][/tex]
To rationalize the denominator, multiply both numerator and denominator by[tex]\( \sqrt{3} \):[/tex]
[tex]\[ W = \frac{42\sqrt{3}}{3} = 14\sqrt{3} \text{ inches} \][/tex]
So, the exact dimensions of the TV are approximately 14 inches by [tex]14\sqrt{3}[/tex] inches, which simplifies to 14 inches by 142 inches. Therefore, the correct answer is B.
Complete question:

Write the equation in slope-intercept form (y=mx+b) that contains the following point with the given slope. Slope = 2 ; (-3, 1) Hint: Use point-slope form first. Then, solve that equation for y.
Answer:
y = 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2, so
y = 2x + c ← is the partial equation
To find c substitute (- 3, 1) into the partial equation
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = 2x + 7 ← equation in slope- intercept form
here,
given point is (-3,2) and slope(m) is 2
so y=mx + b
or 2=2×(-3) +b
or b=8
the equation is
y=mx+b
or y=2x+8
or2x-y+8=0
