"Which of the following are remote interior angles of 5? Check all that apply.


A.1
B.2
C.3
D.4
E.5
F. 6"

Answers

Answer:

A. 1

B. 2

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find remote interior angles of angle 5 for our given triangle.

We can see that angle 5 is an exterior angle. We know that remote interior angles are those, which are inside the triangle and opposite to exterior angle.

We can see that angle 2 and angle 1 are are opposite angles of angle 5 and they are inside our given triangle.

Therefore, option A and B are correct choices.

Final answer:

Remote interior angles are non-adjacent angles within the same triangle. Relative to angle 5, angle 1 and angle 2 are remote interior angles because they are inside the triangle and do not share a vertex with angle 5.

Explanation:

In this mathematics problem, we are asked to find the remote interior angles of a given angle, which are angles that are inside the triangle and non-adjacent to the exterior angle being considered. For example, if we have a triangle with angles labeled 1, 2, 3, 4, 5, and 6, and we want to find the remote interior angles relative to angle 5, we would look for the angles inside the triangle that do not share a vertex with angle 5.

From the available options:

Angle 1 and angle 2 qualify as remote interior angles relative to angle 5 because they are non-adjacent to angle 5 and are within the same triangle.Angle 3 is adjacent to angle 5, so it is not a remote interior angle.Angles 4, 5, and 6 are not pertinent in this case because the question is specifically about the remote interior angles of angle 5, making angles 4 and 6 external to the triangle, whereas angle 5 is the angle in question itself.

Therefore, options A (1) and B (2) are the correct answers to this problem.

At a farmer’s market, a basket of strawberries costs $20 and a basket of peaches costs $18. On Saturday, $430 worth of strawberries and peaches were sold, and a total of 23 baskets were sold. If x represents baskets of strawberries and y represents baskets of peaches, how many baskets of peaches were sold on Saturday?

20x+18y=430
x+y=23

8 baskets
11 baskets
12 baskets
15 baskets

Answers

Final answer:

To find the number of baskets of peaches sold on Saturday, we can set up a system of equations and solve it using elimination or substitution. The answer is 15 baskets Option Dof peaches.

Explanation:

To solve this problem, we need to use a system of equations. Let's call the number of baskets of strawberries x and the number of baskets of peaches y. We can set up the following equations:

20x + 18y = 430 (equation 1)

x + y = 23 (equation 2)

We can solve this system of equations using substitution or elimination. Let's use elimination:

Multiply equation 2 by 18 to make the coefficients of y in both equations cancel:

18x + 18y = 414 (equation 3)

Subtract equation 3 from equation 1 to eliminate y:

(20x + 18y) - (18x + 18y) = 430 - 414

2x = 16

Divide both sides of the equation by 2:

x = 8

Substitute x = 8 into equation 2 to find y:

8 + y = 23

y = 23 - 8

y = 15

Therefore, 15 baskets of peaches were sold on Saturday.

An 8-pound bag of tomatoes costs $5.60. At the same rate, what would be the cost of 11 pounds of tomatoes?
A. $8.50
B. $7.00
C. $7.70
D. $6.50 ...?

Answers

Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.

Determine the value c so that each of the following
functions can serve as a probability distribution of
the discrete random variable
X:(a)
f(x) =c(x2+ 4), for x= 0,1,2,3;
(b)f(x) =c(choose x from2)(choose 3 from 3-x) for x= 0,1,2.

Answers

Final answer:

The value of c, which must be determined for a discrete random variable to serve as a probability distribution, should be 1/30 for the function f(x) = c(x^2 + 4) and 1/3 for the function f(x) = c(choose 2 from x)*(choose 3 from 3-x).

Explanation:

The value of c for a probability distribution needs to be determined such that the total sum of the probabilities is equal to 1. For this, we need to calculate the sum of all possible outcomes and then normalize it to 1.

For the function f(x) = c(x2 + 4), where x = 0, 1, 2, 3, the total sum of the outcomes without the multiplying factor, c, is (02+4) + (12+4) + (22+4) + (32+4) = 4 + 5 + 8 + 13 = 30. The factor c then must be 1/30 for the probabilities to sum up to 1.For the function f(x) = c(choose 2 from x)*(choose 3 from 3-x), where x = 0, 1, 2, the total sum of outcomes without c is (choose 2 from 0)*(choose 3 from 3) + (choose 2 from 1)*(choose 3 from 2) + (choose 2 from 2)*(choose 3 from 1) = 0 + 0 + 3 = 3. Therefore, the factor c for this function must be 1/3.

There are 24 children in a class, 16 brown-haired and 8 black-haired. Two students are randomly selected for a stage performance. Find the probability of the following selection. P(2 black haired children)

Answers

The answer is 7/69.

There are 8 black-haired children among 24 children. The probability of randomly selecting black haired children for the first time is:
P1 = 8/24 = 1/3

Now, there are 7 black-haired children left among 23 children. The probability of randomly selecting black haired children for the second time is:
P2 = 7/23

Since we want both of these events to occur together, we will multiply their probabilities:
P = P1 * P2 = 1/3 * 7/23 = 7/69

Answer: 0.99483

Step-by-step explanation:

Given : A box contains four 40-W bulbs, five 60-W  bulbs, and six 75-W bulbs.

Total bulbs : 4+5+6=15

The probability of selecting a 75-W bulb :[tex]p=\dfrac{6}{15}=0.4[/tex]

For the demand equation, express the total revenue R as a function of the price p per item.
q = −5p + 500
R(p) = ?

Answers

Revenue, R = quantity sold * price

price = p

quantity sold = q = -5p + 500

R(p) = q*p = (-5p + 500) * p = -5p^2 + 500p

Answer: R(p) = -5p^2 + 500p

That is a quadratic function (parabola), which opens downward, so it has a maximum value, which represents the maximum revenue that can be obtained.

That point is the vertex of the parabola. It tells the price and the number of items sold to obtain the greatest revenue. You can obtain the vertex by several ways.

One is finding the roots of the quadratic function; then the vertex is at the middle of the roots.

-5p^2 + 500p = -5p(p-100) => p = 0 and p =100 => vertex is at p = 50 and maximum R = -5(50^2) + 500(50) = 12,500

 
Final answer:

The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q). Given the demand equation q = -5p + 500, the total revenue equation is R(p) = -5p^2 + 500p.

Explanation:

The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q).

Given the demand equation q = -5p + 500, we can substitute q in the total revenue equation with -5p + 500:

R(p) = p * (-5p + 500)

Simplifying, we distribute p to both terms inside the parenthesis:

R(p) = -5p^2 + 500p

So, the total revenue (R) as a function of price (p) is R(p) = -5p^2 + 500p.

Final answer:

The function modeling the total area of the four pens is [tex]A(w) = w * ((750 - 3w) / 2)[/tex]. The maximum area can be found by taking the derivative of this function, setting it to zero, and solving for w.

Explanation:

The subject in question is Mathematics, specifically calculus and problem-solving involving areas. The rancher with 750 ft of fencing intends to make a rectangular area divided into four pens. Let's define w to be the width and l to be the length of the rectangle.

1] Since the total length of the fence is 750 ft and it will be divided into 3 parts for the width and 2 parts for the length, the function for calculating length will be [tex]l = (750 - 3w) / 2[/tex]. Since the area of a rectangle is given by A=w*l, we can substitute our equation for l into our Area function. Therefore, our function will be [tex]A(w) = w * ((750 - 3w) / 2).[/tex]

2] To find the maximum area of the rectangles, you would need to find the derivative of the Area function and solve for w. After that, plug the value of w into the area function to get maximum area.

Optimization problem: what are the dimensions of the lightest open-top right circularcylindrical can that will hold a volume of 1000cm3?Compare the result with the result in example 2. ...?

Answers

So Volume of cylinder is pi*r^2*h = 1,000 

Then lightest one means you have the smallest surface area. Which is one base and then the area of the surface. SA = pi*r^2 + 2pi*r*h 

So now you have 2 equations, so: 

h = 1,000/(pi*r^2) 
So then SA = pi*r^2 + 2pi*r*(1,000/(pi*r^2) = pi*r^2 + 2,000/r 

Derivative of SA is then 2pi*r -2,000/r^2. Set to 0 

2pi*r-2,000/r^2 =0 --> 2pi*r^3 = 2,000 --> r^3 = 1,000/pi --> r = 10/pi^(1/3) 

Now go back to the volume function: pi*r^2*h =1,000 --> 1,000/(pi*100/pi^(2/3)) = h 
h = 10 / pi^(1/3)

Step-by-step explanation:  Given that Sam decides to build a square garden whose area is as follows:

[tex]A=9x^2-24x+16~\textup{square feet}.[/tex]

We are to find the length of one side of the garden.

Since the given garden is of a square shape, so the length of each side is same.

That is, the area of the garden must be a perfect square trinomial.

We have

[tex]A\\\\=9x^2-24x+16\\\\=(3x)^2-2\times 3x\times 4+4^2\\\\=(3x-4)^2.[/tex]

Since the area of a square is (length)², so the length of one side of the garden is [tex](3x-4)~\textup{feet}.[/tex]

Thus, (B) is the correct option.
