Estimate the number of softballs that would fill a 10 by 12 by 24 foot room? Diameter of softball is 3.5 inches. Use the formula of a sphere V = 4/3 (3.14)r^3 for the softball
Answer:
The number of softballs that would fill the room is 221796 softballs
Step-by-step explanation:
First we will determine the Volume of the room.
The volume of a room is given by
[tex]Volume = lwh[/tex]
From the question, the given dimension of the room is 10 by 12 by 24 foot
Hence the volume of the room = 10 × 12 × 24
= 2880 cubic feet (ft³)
Convert to cubic inches
To do this, multiply the answer in cubic feet by (12 × 12 × 12)
(NOTE: 1 foot = 12 inches)
Hence, 2880 cubic feet = 2880 × 12 × 12 × 12 cubic inches
= 4976640 cubic inches
This is the volume of the room.
To estimate the number of softballs that would fill the room, we will determine the number of softballs which would give a total volume that is equal to the volume of the room.
First, we will find the volume of one softball
Diameter of softball = 3.5 inches
∴ Radius of softball, r = 3.5/2 inches = 1.75 inches
∴ r = 1.75 inches
Now, for the volume of one softball
From,
V = 4/3 (3.14)r^3
[tex]V = \frac{4}{3}(3.14)r^{3}[/tex]
[tex]V = \frac{4}{3}(3.14)[/tex] × [tex]1.75^{3}[/tex]
[tex]V = 22.43791667[/tex] cubic inches
This is the volume of one softball
The number of softballs that would fill the room will be
= Volume of the room / Volume of one softball
= 4976640 cubic inches / 22.43791667 cubic inches
=221795.9926
≅221796
Hence, the number of softballs that would fill the room is 221796 softballs
Which symmetry is represented by the function f(x) = |x|?
Answer:
symmetry with respect to the y-axis
Step-by-step explanation:
f(x) = |x| has symmetry with respect to the y-axis. It looks like a V with the vertex at the origin.
The symmetry of the function [tex]f(x)=|x|[/tex] is represented by the y-axis.
The given function is [tex]f(x)=|x|[/tex].
The function can be defined as,
[tex]f(x)=x;\;\;x\geq0\\f(x)=-x;\;\;x<0[/tex]
The function will always give the positive value of y or f(x) for all values of x.
The graph of the function is in the shape of V which is symmetric about the y-axis.
See the attached image.
Therefore, the symmetry of the function [tex]f(x)=|x|[/tex] is represented by the y-axis.

The right line is a 90° clockwise rotation of the left line about the origin. Click the 90° clockwise button. Are these lines the same? What does this mean about how a line changes when you rotate it?
Answer:
Step-by-step explanation:
From the graphs attached,
Let the coordinates of the two points given on the black line in the first graph are (-4, 2) and (-1, 10).
When these points have been rotated by 90° about the origin,
Rule for the rotation will be,
(x, y) → (y, -x)
Therefore, coordinates of the image points will be,
(-4, 2) → (2, 4)
(-1, 10) → (10, 1)
Therefore, red line given given in graph (1) and black line (After rotaion of 90° clockwise) in graph (2) will be same.
Answer:
yes they are the SAME.
Step-by-step explanation:
Determine whether the sequence is arithmetic, geometric or neither. Then, write a recursive rule and an explicit rule, if possible 0.25, 1.75, 3.75, 5.75, 7.75, …
Answer:
Ok, here we have the sequence:
0.25, 1.75, 3.75, 5.75, 7.75, …
First let's define the two most common types of sequences:
Arithmetic: The difference between any two consecutive terms of the sequence is always the same.
Geometric: In this case, the terms are created by multiplicating the previous term by a constant number (and this is for all the terms in the sequence).
Now let's try to see if this is arithmetic, to do it, we select different sets of two consecutive terms and see their difference, if all the differences are the same, then this is an arithmetic sequence:
1.75 - 0.25 = 1.5
3.75 - 1.75 = 2
5.75 - 3.75 = 2
So for the first two terms, the difference is 1.5 and for all the next ones, the difference is 2, then it is not an arithmetic sequence.
(it would be if the first term was -0.25 instead of 0.25).
Now let's try with geometric.
To see if the series is geometric, we should see the quotient of consecutive pairs of numbers, if this quotient is the same for all of them, then this is a geometric sequence:
1.75/0.25 = 7
3.75/1.75 = 2.14
Well, we can see that the quotients are different, then this can not be a geometric sequence.
Then the answer will be neither.
If we want to write a recursive rule will be like an arithmetic sequence, but with the first two terms specified as:
a₀ = 0.25
a₁ = 1.75
aₙ = aₙ₋₁ + 2 for n = 2, 3, 4, .......
The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let x represent the number of new releases, and let y represent the number of classics. If the librarian had a budget of $500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of new-release and classic movies bought? x = 8, y = 45 x = 10, y = 22 x = 16, y = 22 x = 18, y = 18
He'll buy 16 new releases and 22 classic movies.
Let x = number of new releases
Let y = number of classics.
The equation to solve the question will be:
20x + 8y = 500
When x= 16 and y = 22, thus will be:
= 20x + 8y
= 20(16) + 8(22)
= 320 + 176
= 496
Therefore, since this is the number closest to $500, therefore this will be the appropriate number of movies that he can buy.
In conclusion, he'll buy 16 new releases and 22 classic movies.

How to find the domain when given the range? Plz answer quickly. I have test on Friday. Plz just explain to me. I Just Need To Find DOMAIN when given the range.
Answer:
the domain represents all the x values and range represents all the y value
In a function y=mx+b ( linear equation), the problem is giving the y values so plug in the value of each (y) in the equation to get x.
example: the range is : { 2,4,6} find the domain in the function y=x+1
y=x+1 take value 2
2=x+1
x=1 when y=4 then x=3when y=6 then x=5the domain is { 1,3,5}this goes for linear equation
If R1 and R2 be the resistance of the filament of 40 W and 60 W
respectively operating 220 V, then
R1
R2
R1 = R2
R1 R2
Answer:
R2 > R1
Step-by-step explanation:
Here in this question, we want to select which of the relations best gives the answer.
Mathematically;
Power = Voltage * current
But current = voltage/resistance
Power = voltage * voltage/resistance
P = V^2/R
For 40 W
40 = (220)^2 * R1
R1 = 40/(220)^2
For 60 W
60 = (220)^2 * R2
R2 = 60/(220)^2
Mathematically, since we have the same denominator (220)^2 but with 60 greater than 40, that automatically translates to the fact that the value of R2 is greater than the value of R1( You can finish evaluating each of the expressions using a calculator).

Christiana works at Texas Road House and makes $50 each night in tips plus $7.50 per hour. Write a function rule in function notation where M is the total money she makes and h is the number of hours she works in one night.
Answer:
[tex]M(h) = 7.50h + 50[/tex]
Step-by-step explanation:
Let's first get our variables straight. M is how much money you make each night, and h is the amount of hours she works.
This means that M will be what our function is equal to, aka the y-axis. h will be the x-axis.
We know that you earn a rate of $50 per night through tax, and your hours worked doesn't influence this in any way. That means there will be a constant on this function, +50.
We also know that you earn 7.50$ per hour, which is directly influenced by how many hours you work, so we will have [tex]7.50h[/tex].
Combining this all together, we get
[tex]M(h) = 7.50h + 50[/tex].

Two hikers are 22 miles apart and walking toward each other. They meet in 5 hours. Find the rate of each hiker if one hiker walks 2.2 mph faster than the other
Answer:
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.
Step-by-step explanation:
Let suppose that each hiker travels at constant speed, such that kinematic formulas are, respectively:
Hiker A
[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex]
Hiker B
[tex]x_{B} = x_{B,o} +v_{B}\cdot t[/tex]
Relationship
[tex]v_{A} =- v_{B}-2.2\,mph[/tex] (They walk toward each other)
Where:
[tex]x_{A,o}[/tex], [tex]x_{A}[/tex] - Initial and final position of the hiker A, measured in miles.
[tex]x_{B,o}[/tex], [tex]x_{B}[/tex] - Initial and final position of the hiker B, measured in miles.
[tex]t[/tex] - Time, measured in hours.
[tex]v_{A}[/tex], [tex]v_{B}[/tex] - Velocities of hikers A and B, measured in miles per hour.
Given that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 22\,mi[/tex], [tex]x_{A} = x_{B}[/tex] and [tex]t = 5\,h[/tex], the system of equation is reduced to the following:
[tex]0\,mi -(v_{B}+2.2\,mph)\cdot (5\,h) = 22\,mi+v_{B}\cdot (5\,h)[/tex]
[tex]-5\cdot v_{B}-11 = 22+5\cdot v_{B}[/tex]
[tex]10\cdot v_{B} = -33[/tex]
[tex]v_{B} = -3.3\,mph[/tex]
Now, the velocity of the hiker A is:
[tex]v_{A} = - (-3.3\,mph)-2.2\,mph[/tex]
[tex]v_{A} = 1.1\,mph[/tex]
The hikers A and B travel at rates of 1.1 miles per hour and 3.3 miles per hour, respectively.

Maya has 120 cupcakes to sell. Each cupcake is covered with one topping. 1/5 of the cupcakes are covered with peanuts. 1/3 are covered with chocolate chips. 36 are covered with coconut. The rest are covered with sprinkles. How many cupcakes are covered with sprinkles?
Answer:
There are 20 cupcakes covered with sprinkles.
Step-by-step explanation:
To find the amount of cupcakes that are covered with sprinkles you would have to subtract the amount of cupcakes covered with peanuts, the ones covered with chocolate chips and the ones covered with coconut from the total amount of cupcakes:
Total amount of cupcakes=120
cupcakes covered with peanuts=1/5*120=24
cupcakes covered with chocolate chips=1/3*120=40
cupcakes covered with coconut=36
Now, you can subtract the different cupcakes from the total amount to find the quantity left that would be the ones covered with sprinkles:
cupcakes covered with sprinkles=120-24-40-36
cupcakes covered with sprinkles=20
According to this, the answer is that there are 20 cupcakes covered with sprinkles.
The reciprocal of a number is added to three.The result is the quotient of 25 and the number. Find the number
Answer:
8
Step-by-step explanation:
Let x represent the number. Then the reciprocal is 1/x. The quotient of 25 and the number is 25/x. The problem statement tells us ...
3 + 1/x = 25/x
Subtracting 1/x, we have ...
3 = 24/x
x = 24/3 = 8 . . . . . . . . multiply by x/3
The number is 8.
If the product of p*q*r is an irrational number, and p is a rational number,
which of the following statement can be said about g andr
Only a can be irrational
Both q and must be irrational
Both qand may be irrational
may beration
Answer:
only q or r can be irrational
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b, where both a and b are integers and b ≠ 0. The decimal representation of an rational numbers either repeats the sequence of digits over again or terminates at a finite number.
Irrational numbers are numbers that are not rational. The decimal representation of an irrational number does not repeat a sequence of digits over again and never terminates. e.g √2, π.
The product of two irrational numbers is a rational number, the product of two rational numbers is a rational number while the product of a rational and irrational number is an irrational number. Hence since in p*q*r is an irrational number and p is a rational number, If both q and r are irrational then:
q*r = irrational * irrational = rational
p*(q*r) = rational * rational = rational. Since the result is not an irrational number then both q and r cannot be irrational.
But, If either q and r are irrational then:
q*r = irrational * rational = rational * irrational = irrational
p*(q*r) = rational * irrational = irrational. Since the result is an irrational number then only q or r can be irrational
Answer:
1) Both q and r may be rational
2) r may be rational if q is irrational

Dylan is 15, which is 3 years older than twice his sister Savannah’s age. How old is savannah
Answer:
Savannah's age = 6 years
Step-by-step explanation:
Let
Savannah's age = x
Dylan's age = 15
Dylan is 15, which is 3 years older than twice his sister Savannah’s age
Dylan = 2x + 3
Find Savannah's age
2x + 3 = 15
Subtract 3 from both sides
2x + 3 - 3 = 15 - 3
2x = 12
Divide both sides by 2
2x / 2 = 12 / 2
x = 6
Therefore,
Savannah's age = x
= 6 years
Dylan's age = 2x +3
= 2*6 + 3
= 12 + 3
= 15 years
