A rubber ball has a diameter of three inches. What is its volume?
a. 14 in3
b. 4.2 in3
c. 1.4 in3
d. 42 in3
Answers
Answer:
Diameter of the ball = 8 inches
Radius of the ball (r) = diameter ÷ 2 = 8 ÷ 2 = 4 inches
π = 3.14
Surface area of the ball (A) is the same as the surface area for a sphere = 4 π r² = 4 × 3.14 × 4² = 200.96 inches²
Step-by-step explanation:
hi nice to meet you
Using the formula of volume of sphere, the volume of the rubber ball is 14[tex]inches^{3}[/tex] approximately.
What is the volume of sphere?The volume of sphere is the amount of space occupied, within the sphere.
Diameter of sphere = 3 inches
Radius of sphere = 3/2 = 1.5 inches
Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex] = [tex]\frac{4}{3}*\frac{22}{7}*1.5^{3}[/tex] = 14.13 [tex]inches^{3}[/tex]

Step-by-step explanation:
it is reflected so the angles and the sides stay the same.
The statement best describes the relationship between the two figures is: figure JKL is similar to figure J'K'L'.
What are Similar Triangles?Similar triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
As per the given figure,
In triangles ΔJKLand ΔJ'K'L',
side JK = side J'K'
side KL= side K'L'
side JL = side J'L'
According to Side-Side-Side criterion, two triangles are similar if three sides of a triangle are equal to the corresponding sides of the other triangle.
Thus, ΔJKLand ΔJ'K'L' are similar triangles due to equal pairs of corresponding sides.

The sum of four siblings ages is 71. The second child’s age is twice the youngest, the third child’s age is twelve more than the youngest, and the oldest child is four less than three times the youngest. Find each of the siblings ages.
Answers
Answer: 9, 18, 21, and 23 respectively
Step-by-step explanation:
To solve any problem like this, you want to assign a variable to each child because you dont know their age. So lets write an equation and assign variables to these children.
r = first child (youngest)
x = second child
y = third child
z = fourth child (oldest)
We know that r + x + y + z = 71
We also are given info on the comparisons of their ages.
r = r
x = 2r (2 times the youngest)
y = 12 + r (12 more than the youngest)
z = 3r - 4 (4 less than 3 times the youngest)
That was the easy part tbh, now we have to solve for 'r'. We can see that all the ages are a function of the same variable (r), and we know the sum of them is equal to 71. So lets solve for r and then plug that r value into each equation we just derived.
Child #1 (youngest)
[tex]r+2r+(12+r)+(3r-4)=71\\3r+12+r+3r-4=71\\7r+12-4=71\\7r+8=71\\7r=63\\r=9yrs[/tex]
Child #2
[tex]x=2*9=18yrs[/tex]
Child #3
[tex]y=12+r=12+9=21yrs[/tex]
Child #4 (oldest)
[tex]z=3r-4=(3*9)-4=27-4=23yrs[/tex]
Fact Check:

Step-by-step explanation:
Consider the problem of utility over territory. Let’s start simply
with a one-dimensional representation. Consider two actors, 1
and 2, with utility functions defined over a single-dimensional
issue space X = [0, 1], but where the actors can own sections or
“provinces” of the interval. The boundaries between sections are
defined by a vector B = (b1, b2, b3, . . . , bn, 1).
Thus, there are n+ 1 provinces. Define a “size” vector containing the lengths of
each province, S = (b1, b2 − b1, b3 − b2, . . . , 1 − bn). Define for
each actor an “ownership” vector Oi with 1s in the place of the
provinces that it owns and 0s elsewhere.
1. Assume that each actor’s utility function is a simple sum of
how much of the space they own so ui=∑n+1,j=1, oj,sj
(a) Can the players both be made better off by exchanging
existing provinces?
(b) Can the players both be made better off by altering the
boundaries of the existing provinces while preserving the
ownership structure?
(c) Can the players both be made better off by reducing the
number of provinces – for instance, by consolidating
contiguous provinces that are owned by the same actor?
2. Now assume that the utility function is a function of the sum
of the squares of the provinces owned, indicating that there are
increasing returns to the size of a province ui=∑n+1,j=1, (oj,sj)^2
(a) Can the players both be made better off by exchanging
existing provinces (without doing anything else)?
(b) Can the players both be made better off by reducing the
number of provinces – for instance, by consolidating
contiguous provinces that are owned by the same actor?
(c) If the actors are free to adjust both the number of
provinces and the ownership structure, what set of
boundaries is Pareto optimal with this utility function?
2.2 (see formula in the attachments) Consider two states, state 1 and state 2, which can unilaterally
set their tariff rates on imported goods, ti ≥ 0. Each state has an
ideal level for its own tariff, and prefers that the other
side’s tariff be 0, Assume that each side’s utility declines
with the distance between the tariff levels and their ideal point,
as follows
1. Draw the t1, t2 quadrant and draw in the ideal points for each
player.
2. Draw in sample indifference curves for the two states around
their ideal points. What shape are they?
3. Draw in the contract curve between the two ideal points. What
shape is it and why? What equation describes it?
4. The contract curve divides the t1, t2 quadrant into two regions.
How do they differ in terms of how the players could realize
joint gains in each region?
2.3 Consider the utility function u(x) = xρ, where ρ > 0 and x ∈ [0,
1]. Under what conditions would a player with such preferences
be risk acceptant, risk neutral, and risk averse?

Kylie has $2.10 worth of nickels and dimes. She has a total of 24 nickels and dimes altogether. Graphically solve a system of equations in order to determine the number of nickels, x,x, and the number of dimes, y,y, that Kylie has.
Answers
Answer:
Kylie has 6 Nickels and 18 dimes
Step-by-step explanation:
Variable definitions:
x=the number of nickels
y=the number of dimes
One nickel is worth $0.05, so x nickels are worth 0.05x. One dime is worth $0.10, so y dimes are worth 0.10y. The total 0.05x+0.10y equals $2.10:
0.05x + 0.10y = 2.10
Since she has a total of 24 coins, we know x+y must equal 24.
x + y = 24
Write System of Equations:
0.05x + 0.10y = 2.10
x + y = 24
Solve for y in each equation:
0.05x + 0.10y= 2.10 x + y = 24
0.10y = 0.05x + 2.10 y = -x + 24
0.10y = -0.05x + 2.10
0.10 0.10
y = -1/2x + 21
The x variable represents the number of nickels and the y variable represents the number of dimes. Since the lines intersect at the point (6,18) we can say:
Kylie has 6 Nickels and 18 dimes
We want to solve a system of equations to see how many nickels and dimes Kyle has. We will see that she has 6 nickels and 18 dimes.
Finding the system of equations:
First, let's define the variables, we will use:
x = number of nickelsy = number of dimes.We know that there are 24 coins, then:
x + y = 24
We know that the total whort of the coins is $2.10, then:
x*$0.05 + y*$0.10 = $2.10
Then the system of equations is:
x + y = 24
x*$0.05 + y*$0.10 = $2.10
Solving the system of equations.Here we need to graph both equations and find where they do intercept, the graph of the system can be seen below:
We can see that the intersection is at the point (6, 18)
So this means that she has:
6 nickels and 18 dimes.

First you look at the two values of the equation, so the difference between the difference of the two variables is 32, ( 37 - 5 ) then we know that ( 12x - 4x ) 8x . So we know that 8x equals to 32, so ( 32/8 ) equals to x = 4.
