Answer: (27- 4/3 pi) r^3
Step-by-step explanation: 1. Volume of a cube: V= a^3, V= 3^3 , V=27
2. Volume of a sphere: V=4/3 pi r^3 ......
The expression which represents the volume of the foam padding needed to fill the space in the box around the sphere in terms of π is option C. (27 - [tex]\frac{4}{3}[/tex] π) r³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
We have a sphere of radius r inside a cube of side length 3r.
Volume of a cube = (a)³, where a is the side length.
Here a = 3r
Volume of the cube = (3r)³ = 27r³
Volume of a sphere of radius r = [tex]\frac{4}{3}[/tex] π r³
Volume of the foam padding needed to fill the space in the box around the sphere = 27r³ - [tex]\frac{4}{3}[/tex] π r³
= r³ (27 - [tex]\frac{4}{3}[/tex] π)
Hence the volume of the space inside the cube outside the sphere is r³ (27 - [tex]\frac{4}{3}[/tex] π).

Answer:
[tex]\frac{y-2}{4}[/tex]
Step-by-step explanation:
Let's start by factoring everything:
[tex]\dfrac{\frac{y^2+y}{y^2-2y}}{\frac{4y+4}{y^2-4y+4}}=[/tex]
[tex]\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=[/tex]
Now, you can cancel out some terms:
[tex]\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=[/tex]
Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:

A Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0). where is the ball after six seconds?
We have been given that a Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0).
We are asked to find the position of ball after 6 seconds.
We will use horizontal position and vertical position formula to solve our given problem.
Horizontal position is given by formula: [tex]x=v\cdot \text{cos}(\theta)\cdot t[/tex] and vertical position is given by formula: [tex]y=v\cdot \text{sin}(\theta)\cdot t[/tex],where,
v = Velocity,
t = Time,
[tex]\theta[/tex] = Angle to the starting line.
For our given problem [tex]v=1.6[/tex], [tex]t=6[/tex] and [tex]\theta=85^{\circ}[/tex].
[tex]x=1.8\cdot \text{cos}(85^{\circ})\cdot 6[/tex]
[tex]x=10.8 \cdot 0.087155742748[/tex]
[tex]x=0.9412820216784\approx 0.94[/tex]
[tex]y=1.8\cdot \text{sin}(85^{\circ})\cdot 6[/tex]
[tex]y=10.8\cdot 0.996194698092[/tex]
[tex]y=10.7589027\approx 10.76[/tex]
Therefore, the position of ball after 6 seconds would be [tex](0.94,10.76)[/tex].
Answer:
(0.8,9.6)
Step-by-step explanation:
x=1.6*cos85* 6=0.8

How to find if a pair of figure is not dilated version of each other?Dilation of a figure will leave its sides get scaled (multiplied) by same number.
Thus, suppose if a rectangle is dilated, and its sides were of length = L and width = W, then its dilated version would be having length = Ln, and width = Wn where n is the factor of scaling.
At image B (-24, -12) and pre image B (-18, -9),
we can work out the scale factor by (-24/-18) and (-12/-9) both equal 4/3
Using the scale factor to go from the pre image to the image,
We can find C coordinate by pre image C by the scale factor.
C is (-13.5 x 4/3) and (18 x 4/3)
C is (-18, 24)
So, The scale factor is 4/3, which is the mixed numeral of 1 1/3.
To find the pre image of point A;
A is (12/(4/3)) and (-6/(4/3))
A is (9, - 4 1/2)
Hence, the true statement are;
The coordinates of C prime are (–18, 24).
The scale factor is 1 1/3 .
The coordinates of A are (9, –4.5).

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Eggs = 94
Each box Hold= 6 eggs
So, number of boxes required to hold 94 eggs
= 94 / 6
= 15.66
Hence, smallest number of boxes she needs is 15.67

the circle passes through the point (-7,-7). what is the radius?
We have been given image of circle that passes through point [tex](-7,-7)[/tex]. We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point [tex](-2,-1)[/tex].
Now we will use equation of circle to find radius.
[tex](x-h)^2+(y-k)^2=r^2[/tex], where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point [tex](-7,-7)[/tex] and coordinates of center [tex](-2,-1)[/tex] and solve for r as:
[tex](-7+2)^2+(-7+1)^2=r^2[/tex]
[tex](-5)^2+(-6)^2=r^2[/tex]
[tex]25+36=r^2[/tex]
[tex]61=r^2[/tex]
Switch sides:
[tex]r^2=61[/tex]
Now we will take positive square root on both sides:
[tex]\sqrt{r^2}=\sqrt{61}[/tex]
[tex]r=\sqrt{61}[/tex]
Therefore, radius of circle will be [tex]\sqrt{61}[/tex] and center is at point [tex](-2,-1)[/tex].

Each month, Daniel budgets $1230 for fixed expenses, $780 for living expenses, and $160 for
annual expenses. His annual net income is $30,300.
Which statement best describes his monthly budget?
It shows a deficit of $355
It shows a surplus of $355.
It shows a surplus of $515.
It is balanced.
Answer:
B
Step-by-step explanation:
Monthly net income = 30300/12 = $2525
Total monthly expenses = 1230+780+160 = $2170
Surplus = 2525 - 2170 = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.
What is cash flow?The cash balance of liquid assets coming into and going out of a business is referred to as cash flow. Money spent and money received reflect inflows and outflows, respectively.
The cash flow is the difference between outflow and inflow.
Cash flow = outflow - inflow
If the value of the cash flow is negative that means the expense is more.
If the value of the cash flow is positive that means the income is more.
Every month, Daniel spending plans $1230 for fixed costs, $780 for everyday costs, and $160 for yearly costs. His yearly overall gain is $30,300.
Then the Cash flow is calculated as,
Cash flow = ($30,300 / 12) - ($1,230 + $780 + $160)
Cash flow = $2,525 - $2,170
Cash flow = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.

At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories and twice as many onion rings as there are sliders.
According to the question,
Let the amount of onion rings be r and the amount of sliders be s.
Now, it is provided in question that, amount of sliders is twice as the onion rings. In mathematically expressed as,
⇒ 2s = r is the first system of equation.
Then, it is also give that, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories. This representing as,
⇒ r(70) + s(200) = 1020 is the second system of equation.
Therefore, the system of equations 2s = r and r(70) + s(200) = 1020 are that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal.
