A farmer has enough food to feed 20 animals in his cattle for 6 days. How long
would the food last if there were 10 more animals in his cattle?
Answers
Answer:
4 daysb
Step-by-step explanation:
Here the number of animals and the number of days are in inverse proportion. Hence the food will last 4 days.
The food will last for 6 days for 20 animals.
If there were 10 more animals in the cattle, the total number of animals would be 20+10 = 30.
The food will last for the same 6 days but now it would be divided among 30 animals.
Therefore, the food would last for 6 days / 30 animals = 0.2 days per animal.
So, the food will last for 0.2 days if there were 10 more animals in the farmer's cattle.
the opportunity cost of producing one bushel of wheat in canada is equal to 1/2 tv set. the opportunity cost of producing one bushel of wheat in the us is 2 tv sets. if these two countries specialize according to comparative advantage and then trade with each other, .
Answers
If Canada specializes in producing wheat and the US specializes in producing TV sets, both countries will benefit from trade.
To determine this if Canada produces wheat, the opportunity cost is 1/2 TV set. If the US produces wheat, the opportunity cost is 2 TV sets. So, Canada has a comparative advantage in producing wheat. Similarly, the US has a comparative advantage in producing TV sets.
Let's say Canada produces 100 bushels of wheat, and the US produces 100 TV sets. If they trade with each other, Canada can exchange 50 bushels of wheat for 50 TV sets, and the US can exchange 50 TV sets for 50 bushels of wheat. Both countries would benefit from this trade.
Canada would end up with 50 TV sets and 50 bushels of wheat, while the US would end up with 50 bushels of wheat and 50 TV sets. Both countries would be better off than if they had not traded.
Opportunity cost in mathematics is a term that is used to describe the cost of one alternative in terms of the benefits forgone by the best alternative. It can also be represented in terms of mathematical equations.

graph the ellipse give by the equation 49^2 + 16^2 = 784. Rewrite the equation i standard form.
Answers
Answer:
The equation 49^2 + 16^2 = 784 can be rewritten as (x/24.5)^2 + (y/8)^2 = 1.
The standard form of an ellipse is (x/a)^2 + (y/b)^2 = 1, where a and b are the lengths of the major and minor axes, respectively. In this case, a = 24.5 and b = 8.
To graph the ellipse, we can use the equation in the standard form and plot points that satisfy the equation. The center of the ellipse is (0,0) and it has a major axis of 24.5 and minor axis of 8.
The graph of this ellipse will look like an oval, with the center at the origin, major axis along the x-axis and minor axis along the y-axis.

What is Trigonometry?The area of mathematics known as trigonometry examines the correlation between the ratios of a right-angled triangle's sides to its angles. Trigonometric ratios, such as sine, cosine, tangent, cotangent, secant, and cosecant, are used to study this relationship. The concept of trigonometry was developed by the Greek mathematician Hipparchus, and the word trigonometry is a derivative of Latin from the 16th century.
One of the most significant area of mathematic is rigometry. The words "Trigonon" and "Metron," which mean respectively "triangle" and "measure," are combined to form the word "trigonometry." It is the investigation of how a right-angled triangle's sides and angles relate to one another. Therefore, using formulas and identities based on this relationship aids in determining the measure of a right-angled triangle's unknown dimensions.

The amount loaned at 6% was $9200. The solution has been obtained by making and solving the equations.
What is an equation?
A claim that two expressions are equal and connected by the equals sign "=" is the mathematical definition of an equation. The two expressions need not be entirely composed of variables; one expression may have variables while the other may not.
We are given that a bank loaned out $12,000 and a part of it at the rate of 6% per year and the rest at the rate of 16% per year.
Let the amount loaned at 6% be 'x'
So, amount loaned at 16% will be '12,000 - x'
The total interest received was $1000.
Therefore,
⇒6%x + 16%(12000-x) = 1000
⇒0.06x + 1920 - 0.16x = 1000
⇒920 = 0.1x
⇒9200 = x
Hence, the amount loaned at 6% was $9200.

How do i solve for value of m
Answers
From my best knowledge I assume this has to do with triangle angles and linear expressions.
All triangles add up to 180°, so we will use this formula with the triangle angels given.
(4m + 6) + (5m + 3) = 180°
9m + 9 = 180°
(Combined like terms) 4+5 & 6+3
9m = 171 (Subtract 9 from 180 = 171)
m = 19 (Divide 9 from 171)
So, m in the expression equals 19 but let’s double check.
(4(19) + 6) + (5(19) + 3) = 180
4 x 19 = 76 + 6 = 82°
(So that angle separately is 82 degrees.)
5 x 19 = 95 + 3 = 98°
(So that angle separately is 98 degrees.)
Add both angles - 82° + 98° = 180°
So it’s a true formula! Both angles in the triangle add to 180 as it should.
But as for the original question being asked, yes m = 19

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
We know that
The river is 310 miles long.
The race is 42 miles long.
So, if we want to know know how many times as long as the race is the river, we just need to use this expression
River=x(race)

find the volume common to two spheres, each with radius r, if the center of each sphere lies on the surface of the other sphere.
Answers
The volume of the common region between two spheres, each with radius r, is 4/3π(r^3 - 32r^6).
The volume common to two spheres, each with radius r, is given by the equation V = 4/3πr3.
The volume of the common region between two spheres, each with radius r, is given by the formula:
V = 4/3π(r^3 - (r^2 - d^2)^3/2),
where d is the distance between the centers of the spheres.
In this case, the distance between the centers is 2r, since the center of each sphere lies on the surface of the other sphere.
Thus, the volume of the common region is 4/3π(r^3 - (r^2 - (2r)^2)^3/2)
= 4/3π(r^3 - (r^2 - 4r^2)^3/2)
= 4/3π(r^3 - (r^2 - 4r^2)^3/2)
= 4/3π(r^3 - (4r^2)^3/2)
= 4/3π(r^3 - 64r^6/2)
= 4/3π(r^3 - 32r^6)
= 4/3π(r^3 - 32r^6)
= 4/3π(r^3 - 32r^6).

Answers
The quantity which represents the 0.031 in the given formula of compound interest, the value represents the annual compound interest rate 3.1%, So option A is correct
What is compound interest?A loan or deposit amount is subject to compound interest as interest. In everyday life, it is the most prevalent idea. Both the principal and the interest accrued over time affect the compound interest for a given amount. Between compound and simple interest, this is the primary distinction.
[tex]A = P[1 + r/n]^{nt}[/tex]
Where,
A = compound interest
P = Principle Amount
r = Interest rate
n = number of period for which interest is calculated
t = time
Given that,
A equal to 2,400 plus quantity 1 plus 0.031 over 4 end quantity all raised to the power of 4 times t
[tex]A = 2400[1 + 0.031/4]^{4}[/tex]
So, here we can see that r is equal to 0.031
It represents the annual compound interest rate of the compound interest
Hence, it is a annual compound interest which has value of 3.1%

The function to be used for answering questions is
[tex]f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]
a. Graph
Graph is plotted using online graphing tool. 2 points identified are (-4, 9) and (-3, 3)
b. Domain and Range
First let's understand what domain and range are
Definition of domain
The domain of a function, y = f(x), is the set of input(x) values for which the function is real and defined
The function has no undefined points nor domain constraints. You can see that the graph goes to infinity for negative and positive x values Therefore, the domain is :
[tex]-\infty \: < x < \infty \:[/tex]
which can be expressed in interval notation as:
[tex]\left(-\infty \:,\:\infty \:\right)[/tex]
Definition of range
The range of a function y = f(x) is the set of values for y over the domain for which the function is defined
As [tex]x \rightarrow \infty[/tex], [tex]y \rightarrow 1[/tex]
y never quite reaches 0 but its value approaches 1 and therefore the range is
[tex]f(x) > 1\\\\[/tex]
In interval notation:
[tex]\left(1,\:\infty \:\right)[/tex]
c. End Behavior
The end behavior of a function f(x) refers to how the function behaves when the variable x increases or decreases without bound. In other words, the end behavior describes the ultimate trend in the graph of f(x) as [tex]x \rightarrow \pm \infty[/tex]
In this particular function we see that as [tex]x\to \:+\infty \:,\:f\left(x\right)\to \:1\\[/tex]
and as [tex]x\to \:-\infty \:,\:f\left(x\right)\to \:\infty\\[/tex]
d. Point (-3, 3)
By pure chance I chose this point as one of the points asked for in part a because I was looking for integer values I don't think it matters that there is repetition
(-3, 3) is plotted on the graph as point A
3. Evaluate f(-3)
We have
[tex]f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]
To find f(-3) substitute -3 for x in the above function:
[tex]f(-3) = 8\left(\dfrac{1}{4}\right)^{-3+4}+1\\\\= 8\left(\dfrac{1}{4}\right)^1} + 1\\\\\\= 8\left(\dfrac{1}{4}\right) + 1\\\\= 2 + 1 \\\\= 3[/tex]
So f(-3) = 3
Answer:
a) See attachment 1.
b) Domain: (-∞, ∞)
Range: (1, ∞)
c) As x → -∞, f(x) → ∞
As x → ∞, f(x) → 1⁺
d) See attachment 2.
e) See below.
Step-by-step explanation:
Given exponential function:
[tex]f(x)=8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]
Part aTo find the y-intercept, input x = 0 and solve for y:
[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{0+4}+1[/tex]
[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{4}+1[/tex]
[tex]\implies f(0)=8\left(\dfrac{1}{256}\right)+1[/tex]
[tex]\implies f(0)=\dfrac{1}{32}+1[/tex]
[tex]\implies f(0)=\dfrac{33}{32}[/tex]
[tex]\implies f(0)=1.03125[/tex]
Therefore, the y-intercept is (0, 1.03125).
Substitute x = -2 into the function to find a second point on the curve:
[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{-2+4}+1[/tex]
[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{2}+1[/tex]
[tex]\implies f(-2)=8\left(\dfrac{1}{16}\right)+1[/tex]
[tex]\implies f(-2)=\dfrac{1}{2}+1[/tex]
[tex]\implies f(-2)=\dfrac{3}{2}[/tex]
[tex]\implies f(-2)=1.5[/tex]
Therefore, a second point on the curve is (-2, 1.5).
Part bThe domain of a function is the set of all possible input values (x-values).
The domain of the given function is unrestricted:
Interval notation: (-∞, ∞)The range of a function is the set of all possible output values (y-values).
As the exponential part of the function is always positive, the range of the given function is restricted:
Interval notation: (1, ∞)Part cAs x approaches negative infinity, the function approaches positive infinity:
As x → -∞, f(x) → ∞As x approaches positive infinity, the function approaches f(x) = 1.
As x → ∞, f(x) → 1⁺Part dSee attachment 2.
Part eSubstitute x = -3 into the function:
[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{-3+4}+1[/tex]
[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{1}+1[/tex]
[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)+1[/tex]
[tex]\implies f(-3)=2+1[/tex]
[tex]\implies f(-3)=3[/tex]
Bridge is a card game in which the deck of 52 cards is randomly and equally divided among the 4 players.So each player gets 13 cards. What is the probability that one player receives all the 13 hearts?
Answers
The probability that one player receives all the 13 hearts is 1/2598960.
How likely something is to occur can be determined using probability. For many events, it is challenging to make an accurate prediction.
The number of ways to distribute the 13 hearts among the 4 players is 4!. The number of ways to distribute the remaining 39 cards among the 4 players is 39!/(13!13!13!13!). Hence, the total number of ways to distribute the 52 cards among the 4 players is (52!)/(13!13!13!13!).
Therefore, the probability that one player receives all the 13 hearts is (4!)/((52!)/(13!13!13!13!)) = 1/((52515049)/(13121110)) = 1/2,598,960.
