145 over 1000 in simplest form
29/200. 145 / 5 = 29, and 1000 / 5 = 200. 29 is a prime, so that's the lowest you can go: 29/200.

Answer:
see below
Step-by-step explanation:
65 - 32 = 13
13 divide by 65 = 0.20
0.20 x 100% = 20%
so the percentage drop is 20%

Flight Distances
Chicago O'Hare is a busy international airport. The map shows the flight distance from
Chicago O'Hare to several cities. Lee conjectured the flight distance from Chicago to
Istanbul is the same as the flight distance from Chicago to Sao Paulo when the distances
are rounded to the nearest thousand.
To Beijing
5,784 miles
5,784 miles
S
6,579 miles
Chicago, Illinois
Istanbul, Turkey
Beijing, China
5,252 miles
Sao Paulo, Brazil
4. Construct Arguments Describe at least one way you could
construct an argument justifying Lee's conjecture.
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.

Use the slope formula to find the slope m .
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3) and (x₂, y₂ ) = (3, - 5)

2. Suppose that four times the square of a number equals 20 times that num-
ber. What is the number?
3. Twice the square of the sum of a number and 3 is 98. Find the number. help me in number 2 and 3 please
Answer:
2. the answer is 5 because the square of 5 is 25 and 4 x 25 = 100 which is 20 x 5
Step-by-step explanation:
We are required to find the unknown number from the expression
2.
let
the number = x
four times the square of a number equals 20 times that number
4x² = 20x
Divide both sides by 4x
x = 5
The number is 5
3.
let
x = the unknown number
Twice the square of the sum of a number and 3 is 98
sum of a number and 3 = x + 3
square of the sum = (x+3)²
Twice the square = 2(x + 3)²
2(x + 3)² = 98
2(x² + 6x + 9) = 98
2x² + 12x + 18 = 98
2x² + 12x +18 - 98 = 0
2x² + 12x - 80 = 0
x² + 6x - 40 = 0
using factorization method to solve the quadratic equation
x² + 10x - 4x - 40 = 0
x(x + 10) - 4(x + 10) = 0
(x + 10) ( x - 4) = 0
x + 10 = 0 or x - 4 = 0
x = -10 or x = 4
Therefore, the unknown number is -10 or 4

Write the equation in Slope Intercept form for the line that passes through (5,-7) and is perpendicular to the y-axis. m= _______ Equation: ________________________________
Answer:
35
Step-by-step explanation:
Answer:
y=-7
m=0
Step-by-step explanation:
y=mx+b
line is perpendicular to y axis and passes through point(5,-7)
which means that our line equation is y=-7
so y=0*x-7
so m=0 and b=-7

Fifth option
Step-by-step explanation:
Simplify the solution set, so it now looks like this: -2 < x < 8Look for the graph that looks the most like the simplified solution set. The fifth option has both numbers that's in the solution set, -2 and 8. Therefore, it is correct. It's also in the order on the number line that the solution set is in, so that's another way I know it's correct.How do you solve a perpendicular equation?
Step-by-step explanation:
First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

Your internet provider offers two different plans. One plan costs $.02 per email
plus a $9 monthly service charge. The other plan costs $.05 per email with no
service charge.
a. Write a system of equations to model the cost of the two internet plans.
b. For how many email messages will both plans cost the same?
c. If you send and receive about 500 email messages per month, which plan
should you use?
a.) y= 0.2x + 9 and y= 0.5x
b.) 30 emails
c.) the first plan
Step-by-step explanation:
a.) cost per email is a variable
b.) graph and find intersection of the lines
c.) plug in 500 for x in both equations
The number of email messages where both plans will cost the same will be 300 messages.
The system of equations to model the cost of the two internet plans based on the information given will be:
Internet provider 1 = 9 + 0.02m
Internet provider 2 = 0.05m
where m = number of mails
The number of email messages where both plans will cost the same will be:
9 + 0.02m = 0.05m
Collect like terms
0.05m - 0.02m = 9
0.03m = 9
m = 9/0.03
m = 300
When there's 500 messages for the month, the cost for each plan will be:
Internet provider 1 = 9 + 0.02m
= 9 + 0.02(500)
= 9 + 10
= 19
Internet provider 2 = 0.05m
= 0.05(500)
= 25
Therefore, based on the calculation, the first plan is cheaper.

A men's shoe size is related to his foot length and can be modeled by the equations s=1.7f -7.2, where s is shoe size and fis foot length, in inches. What is the shoe size of a man whose foot measures 9 inches?
Answer:
B. 8
Step-by-step explanation:
Given the equation, [tex] s = 1.7f - 7.2 [/tex],
where,
s = shoe size,
f = foot length,
To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.
[tex] s = 1.7f - 7.2 [/tex]
[tex] s = 1.7(9) - 7.2 [/tex] (substitution)
[tex] s = 15.3 - 7.2 [/tex]
[tex] s = 15.3 - 7.2 [/tex]
[tex] s = 8.1 [/tex]
His shoe size is approximately 8 inches

G)
all angles of a triangle add up to 180.
the square in the bottom right of the triangle is 90 btw
2x + x + 90 = 180
3x + 90 = 180
3x + 90 - 90 = 180 - 90
3x = 180 - 90
3x = 90
3x/3 = 90/3
x = 30
H)
this is an Isosceles triangle.
that means the bottom two angles are equal.
75 + 75 + x = 180
x + 150 = 180
x + 150 - 150 = 180 - 150
x = 180 - 150
x = 30
I)
2m is supplementary to the bottom right angle of the triangle.
that means they add together to make 180.
80 + 30 + (180 - 2m) = 180
110 - 2m = 180 - 180
110 - 2m = 0
110 = 2m
110/2 = m
55 = m
J)
to save time I'm not going to write out the steps, its the same as the i.
2x + 3x + (180 - 120 ) = 180
5x + 60 = 180
5x = 180 - 60
5x = 120
x = 120/5
x = 24
K)
imagine this as a triangle and a square.
sorry I'm not sure how to explain this -.-
but the equation would be
k + k + 90 = 180
2k + 90 = 180
2k = 180 - 90
2k = 90
k = 45

Answer:

First, since ¨in debt¨ is describing negative value, all of the expressions that have positive 225 is incorrect. Also, since the term ¨triple¨ is describing multiplcation, any expression that does not have multiplication is also incorrect. This process of elimination leads to two answers, which both are correct.
