Answer: 150 miles
Step-by-step explanation:
The distance between Chicago and Indianapolis is approximately 150 miles.
To find the distance between Chicago and Indianapolis using their latitude and longitude coordinates, we can apply the Pythagorean theorem. The distance between two points on the Earth's surface can be approximated by considering the Earth as a flat plane, which is reasonable for relatively short distances like the one between these two cities.
The difference in latitude (north-south distance) between Chicago and Indianapolis is:
[tex]\[ 42N - 40N = 2N \][/tex]
The difference in longitude (east-west distance) between the two cities is [tex]\[ 86W - 88W = 2W \][/tex]
Since each degree is approximately 53 miles, we can calculate the north-south distance and the east-west distance:
North-south distance in miles:
[tex]\[ 2N \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]
East-west distance in miles:
[tex]\[ 2W \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]
Now, we can use the Pythagorean theorem to find the straight-line distance (the hypotenuse of the right triangle formed by the north-south and east-west distances):
Let [tex]\( d \)[/tex] be the distance between the two cities, then:
[tex]\[ d^2 = (106 \text{ miles})^2 + (106 \text{ miles})^2 \] \\[/tex]
[tex]\[ d^2 = 11236 \text{ miles}^2 + 11236 \text{ miles}^2 \] \\[/tex]
[tex]\[ d^2 = 22472 \text{ miles}^2 \] \\[/tex]
[tex]\[ d = \sqrt{22472 \text{ miles}^2} \] \\[/tex]
[tex]\[ d \approx 150 \text{ miles} \][/tex]

Is 5(2x-3y) and 10x-3y equivalent?
Answer:
No
Step-by-step explanation:
Apply the distributive property to 5(2x - 3y):
Multiply 5 by each term inside the parentheses.
5(2x - 3y) = 10x - 15y
The other expression is 10x - 10y.
The terms 10x in both expressions are equal.
Since the term -15y is not equal to the term -10y, the expressions are not equivalent.

Then, add 175 and y should= 174.68.
a hammer that normally sells for $24 is on sell for $12. what percentage is the discount?
Answer:
50%
Step-by-step explanation:
You can figure out the percentage that it is off by diving the price it is not at (12) by the full amount (24) and then multiplying it by 100 because it is a percent.
(12/24)= 0.5
(0.5)*(100)= 50%
Your graphing the speed your car goes on the interstate from the time you enter the ramp until you arrive at the next exit ramp 6 miles away. The speed of the highway is 70 mph. The X axis represents time and Y represents speed. The graph has five tick marks on the X axis and 10 tick marks on the Y axis. What would be a good scale for each axis?
Answer:
1 minute on the x-axis; 10 mph on the y-axis
Step-by-step explanation:
The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.
Answer:
1 minute on the x-axis; 10 mph on the y-axis

the root of quadratic equation are (3-√3) and (3+√3). find its equation
Answer: [tex]x^{2} - 6x +6 = 0[/tex]
Step-by-step explanation:
The formula for finding quadratic equation is given as :
[tex]x^{2}[/tex] - sum of roots[tex](x)[/tex] + product of roots = 0
sum of roots implies :
(3-√3)+(3+√3) =6
product of roots implies :
(3-√3) x (3+√3) = 9 +[tex]3\sqrt{3}[/tex] - [tex]3\sqrt{3}[/tex] - 3
(3-√3) x (3+√3) = 6
substituting into the equation we have:
[tex]x^{2} - 6x +6 = 0[/tex]
Jill drove the 200 miles to Cincinnati at an average speed of 10 miles per hour faster than her usual average speed. If she completed the trip in 1 hour less than usual, what is her usual driving speed, in miles per hour
Let [tex]v[/tex] be the usual speed, and [tex]t[/tex] be the usual time.
Following the equation [tex]s=vt[/tex], where s is the space, v is the velocity and t is time, we know that usually we have
[tex]200=vt[/tex]
But this time we were 10mph faster and it took one hour less, so we have
[tex]200=(v+10)(t-1)[/tex]
Since both right hand sides equal 200, they must equal each other:
[tex]vt=(v+10)(t-1)=vt+10t-v-10 \iff 10t-v-10=0 \iff v=10t-10[/tex]
Plug this value in the first equation and we have
[tex]200=vt=(10t-10)t \iff 10t^2-10t-200=0[/tex]
This equation has solutions [tex]t=-4,\quad t=5[/tex]. We can only accept positive solutions, so we have t=5. We finally deduce, again from the first equation,
[tex]200=5v \iff v=\dfrac{200}{5}=40[/tex]

Which statements are true?
Select each correct answer.
a. 30x4−12x3=6x3(5x−2)
b. 4x2+10x=2x(2x+5)
c. 100x3+5=5x3(20x+1)
d. 8x3−6x=2x3(4−3x3)
Answer:
30x^4−12x^3=6x^3(5x−2) = True
4x^2+10x=2x(2x+5) = True
100x^3+5=5x^3(20x+1) = False
8x^3−6x=2x^3(4−3x3) = False
Step-by-step explanation:
The statements which are true are 30x4−12x3=6x3(5x−2) , 4x2+10x=2x(2x+5) and 100x3+5=5x3(20x+1)
To determine which of the statements are true, we can simplify each equation and compare.
Option a :
30x4−12x3=6x3(5x−2): Factoring out the common term we can see this equation is true.
Option b:
4x2+10x=2x(2x+5): After simplifying both sides we find that 2x(2x + 5) = 4x2 + 10x, so statement (b) is true.
Option c:
100x3+5=5x3(20x+1): Attempt to simplify this equation as 5x3(20x + 1). Since this simplification holds, statement (c) is also true.
Option d:
8x3−6x=2x3(4−3x3): Simplifying the right side does not give us the left side; thus, statement (d) is false. The correct form would be 2x(4x2 - 3), assuming a typo in exponent notation.

Two cylinders are similar. The volume of the larger cylinder is 343ft3 and the volume of the smaller cylinder is 125ft3. The height of the smaller cylinder is 5ft. What is the height of the larger cylinder? Enter your answer in the box.
Answer:
The answer would be 7ft.
Step-by-step explanation:
Let the radius of the cylinder be rft. and its height be hft. Again the radius of the larger cylinder is R ft and its height is H ft. Given h = 5 ft.
As the cylinders are similar we can say [tex]R/r[/tex] = [tex]H/h[/tex]
Now the volume of the smaller cylinder is πr²h = 125
and that of larger one is πR²H = 343
SO πR²H/πr²h = 343/125
⇒ H²/h² × H/h = 343/125
⇒ H³/h³ = 7³/5³
⇒ H/h = 7/5
⇒ H = 7/5 × h = 7/5 × 5 = 7ft

Let f(x)= x2 - 14 and g(x) = 6-X.
Find (fq)(7).
Answer:
[tex](fg)(7) = - 35[/tex]
Step-by-step explanation:
The given functions are:
[tex]f(x) = {x}^{2} - 14[/tex]
and
[tex]g(x) = 6 - x[/tex]
We want to to find
[tex](fg)(7)[/tex]
Note that:
[tex](fg)(x) = f(x) \times g(x)[/tex]
We substitute the functions to obtain:
[tex](fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)[/tex]
We now substitute x=7, to get:
[tex](fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)[/tex]
This implies that
[tex](fg)(7) =( 49-1 4 ) \times (6 - 7)[/tex]
[tex](fg)(7) = 35 \times - 1 = - 35[/tex]

You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters. Write a expression that represents the total number of quarters you take with you when you go shopping. How much money do you have left
Answer:
a) 28 quarters
b) 14 quarters
Step-by-step explanation:
We are given the following in the question:
Number of quarters = 20 quarters
Number of quarters in room = 40%
Total number of quarter in room =
[tex]=40\%\times (20)\\\\=\dfrac{40}{100}\times 20\\\\=8[/tex]
Thus, the total quarters taken to shopping =
[tex]=20 +40\%\times (20)\\\\=20+8\\=28[/tex]
Thus, 28 quarters were taken to shopping.
Quarter spent on shopping = 50%
Total number of quarter spent in shopping =
[tex]=50\%\times (28)\\\\=\dfrac{50}{100}\times 28\\\\=14[/tex]
Money left =
Money taken for shopping - Money spent
[tex]= 28-14\\=14[/tex]
Thus, we are left with 14 quarters after shopping.

which shape does NOT have perpendicular
perpendicular lines? Mark your answer.
Answer:
Perpendicular lines are lines that cross one another at a 90° angle. They have slopes that are opposite reciprocals of one another. Unlike parallel lines that never touch, perpendicular lines must intersect.
Therefore, the shape with 2 lines that don't intersect/touch each other, is the shape that does not have perpendicular lines.

Tom rented a truck for one day. There was a base fee of 19.95 , and there was an additional charge of 85 cents for each mile driven. Tom had to pay 216.30 when he returned the truck. For how many miles did he drive the truck?
Answer:
231 miles.
Step-by-step explanation:
Tom rented a truck with a base fee of 19.95. You will subtract this from the total since you just want to get the mileage.
Tom is getting charged .85 cents per mile driven.
Tom payed 216.30 subtotal minus the 19.95 base fee since we are trying to only see how many miles he drove.
(216.30-19.95=196.35) This will be total for each mile. All we need to do is divide to get the total of miles
(196.35÷.85= 231)
231 is the number of miles Tom drove.
