Answer:
4. Given that the distance from one place to another are placed in ranges of a thousand, then the distances from Sao Paulo to Chicago Illinois which is 5,252 miles and from Chicago Illinois to Istanbul Turkey which is 5,784 miles will be in the same 5,000 kilometer distance range and both distances will taken as the same distance
The same situation can also be arrived at by rounding down both distances
Step-by-step explanation:
The given information are;
The flight distances given;
From Sao Paulo to Chicago Illinois = 5,252 miles
From Chicago Illinois to Istanbul Turkey = 5,784 miles
From Beijing China to Chicago Illinois = 6,579 miles
Lees conjectured the flight distance from Chicago to Istanbul is the same as the flight distance from Chicago Sao Paulo when the distances are rounded to the nearest thousand
Placing the distances in ranges of 1000, we have the 5,252 miles and the 5,784 miles will be in the same 5,000 to 5,999 miles range.

If cat food is sold in 20 lb bags, what is the least number of bags of cat food needed for one year at this shelter, if 10 lbs of cat food is consumed per week?
Answer:
26 weeks!
Step-by-step explanation:
Hello there!
There are 52 weeks in a year, believe it or not! So, if 1 bag of food was 10 lbs, then it would be 1 bag of 10lbs x 52 weeks, so it would be 52 bags. However, we are dealing with 20 lb bags, which will last twice as long as the 10 lb bag! So, if 1 bag will last 2 weeks, and there are 52 weeks in a year, then it is weeks divided by number of weeks it takes to consume 1 bag, 52 divided by 2. 52 divided by 2 is 26.
So in 1 year, the shelter will need 26 bags of 20 lb cat food!
Hope I helped!

What is the correct answer for Dean's problem? Explain where he went wrong.
Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.

Mr. Santos wanted to know the height of the tree. He observed from a point A that the angle of elevation of the top of the tree is 36 degrees. He then moved backwards 50 ft away from the initial point A, the angle of elevation of the top of the tree was 22 degrees. Find the height of the tree.
Answer:
The height of the tree is approximately 45.51 ft.
Step-by-step explanation:
The given information are;
The angle of elevation of the top of tree is 36 degrees
The distance backwards Mr. Santos moved = 50 ft.
The new angle of elevation of the top of the tree = 22 degrees
Therefore, we have;
The angle opposite to the 50 ft. side = 180 - (180 - 36) - 22° = 14°
Therefore, we have, by sine rule;
50/(sin(14)) = X/(sin(22))
X = (sin(22)) × 50/(sin(14)) ≈ 77.42 ft.
The height of the tree, T = X × sin(36°)
T = 77.42 ft. × sin(36°) ≈ 45.51 ft.
The height of the tree is approximately 45.51 ft

Step-by-step explanation:
Divide each term by 3 and simplify. Move all terms not containing x to the right side of the equation.
Answer:
[tex]\huge\boxed{x=7}[/tex]
Step-by-step explanation:
In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.
Let's apply the distributive property on the left side:
[tex](3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9[/tex]
Add 30 to both sides:
[tex]3x - 30 + 30 = -9 + 30\\\\3x = 21[/tex]
Divide both sides by 3:
[tex]3x \div 3 = 21 \div 3\\\\x = 7[/tex]
So x = 7.

Determine an interest rate less than 15%, a period of investment greater than two years, and a regular payment that will result in the total amount of interest you earn being equal to the total amount of money you put in?for example, under what conditions will you have a future value of $1 000 000, having earned $500 000 interest?)
Answer:
It will take 5.29 years to double our money if we invest $500 at 14 percent interest.
Step-by-step explanation:
Let we invest $500 with the interest rate of 14% ,
Now we will find the time it is going to take to double the money
here, we use the formula of compound interest [tex]A= P( 1+\frac{r}{n}) ^{nt}[/tex]
Here, A = the amount yielded,
P = principal,
r = interest rate ,
n = number of times per year,
and t = time invested.
Now, put A= 1000 , P= 500 , R= 0.14 T= x and N= 1
[tex]1000=500(1+ 0.14)^x[/tex]
[tex]1000=500(1.14)^x[/tex]
[tex]2=1.14^x[/tex]
[tex]\log_{1.14} (2)=x[/tex]
[tex]x=5.29[/tex]
so , It will take 5.29 years to double our money if we invest $500 at 14 percent interest.
Hence , the answer is 5.29 years .

What is 2/5 of a book to 1/2 of an hour as a unit rate?
Answer: 4/5 book per hour
Step-by-step explanation: in this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Step-by-step explanation:
hi! if the leading term is 8x^9, this means that this is the term with the highest power. therefore, its degree is 9.
The degree of the given polynomial is 9
What is a polynomial expression?Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11
Given here; a polynomial function with leading term 8x⁹

Sue is offered a job reshelving books in the University of Montana library from noon until 1 p.M. Each Friday. Her reservation wage for this task is $10 per hour. If the library director offers Sue $100 per hour, how much economic surplus will she enjoy as a result of accepting the job? Now suppose the library director announces that the earnings from the job will be divided equally among the 400 students who live in Sue's dormitory. Will Sue still accept? Explain how your answers to parts a and b illustrate one of the incentive problems inherent in income redistribution programs.
Answer:
Step-by-step explanation:
Sue's initial wage per hour = $10
Sue's wage per hour after the increase = $100
a. Economic surplus to be enjoyed = $100 - $10
= $90
Sue would enjoy an economic surplus of $90.
b. No, because in this case the wage per hour for each 400 student would be;
= [tex]\frac{100}{400}[/tex]
= $0.25
= 25 cents
Redistribution of income is the act of equal sharing of wealth among a certain number of people.
The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.
Though the income incentive redistribution programs reduce poverty, but it may be unfair.

B. t = 300d + 100
C. d = 350t
D. d = 300t + 100 Minutes (t) Meters (d)
2 700
3 1,050
5 1,750
10 3,500
Answer:
d = 350tStep-by-step explanation:
From the information given, we need to get the rate of change of distance which is the velocity (slope.)
velocity = Δd/Δt
v = d2-d1/t2-t1
from the table;
when t = 2, d = 700
when t = 3, d = 1050
v = 1050/750/3-2
v = 350/1
v = 350
Since v = d/t
350 = d/t
cross multiply
350t = d
Rearrange:
d = 350t
Hence the equation that represents the information is d = 350t

Hi there! :)
C. has both jump and infinite discontinuity.
Evaluate both piecewise functions at x = 1;
1 / (x + 1) = 1 / ((1) + 1) = 1/2
2x - 1 = 2(1) - 1 = 1
As the piecewise functions contain different y-values when evaluated at
x = 1, there is a jump discontinuity at x = 1.
However, the first function also contains a vertical asymptote or infinite discontinuity where it is undefined, or at x = -1. (1 / 0 = undefined). This means that the function also contains an infinite discontinuity.
Therefore, the correct choice is:
C. has both jump and infinite discontinuity.
