On a map of Illinois, the distance between Chicago and Algonquin is 3.2 centimeters. If 2 centimeters = 40 kilometers, what is the approximate distance between the two cities?

Answers

Answer 1

Final answer:

The approximate distance between Chicago and Algonquin is 64 kilometers.

Explanation:

To find the approximate distance between Chicago and Algonquin, we can use the given scale of 2 centimeters = 40 kilometers. Since the distance on the map is 3.2 centimeters, we can set up a proportion to find the actual distance:

2 cm / 40 km = 3.2 cm / x km

Cross multiplying, we get 2x = 40 x 3.2, which simplifies to 2x = 128. Dividing by 2, we find that x is equal to 64. Therefore, the approximate distance between Chicago and Algonquin is 64 kilometers.

which expression is equivalent to 2^2×2/2^4

Answers

First step is to simplify the equation so that it makes our life easier! Since 2^2 is equivalent to 4, we can plug that into the equation. Then we can also simplify 2^4 to 16. Now it should look like this:

(4)(2)/16

Now we can solve. 4(2) = 8 so now we have 8/16. 8/16 simplifies to 1/8 when you divide the numerator and the denominator by 8. So there you go! Your final answer is 1/8! I really hope that helped you out, and happy holidays!

6•10^5 is how many times as large as 3•10^3

200 times greater because you take 6*10^5 and you get 600,000 then you find out 3*10^3 and it equals 3,000 so you take 600,000 and divide it by 3,000 and you get 200 and that is how many times greater it is.

Please help me with math please, they are number lines.

Answers

The answer is D because the inequality solves to x>/= to -4

To solve this you need to get x by itself, so to do this you simply subtract 3 from each side of the equation making it...

x >= -4

The arrow points to the right meanings that on the graph the arrow will go towards the right.

You could also think about it that x is greater than or equal to -4, so the arrow will be going towards the positive numbers from -4 meaning the arrow will go towards the right.

Also since it is greater than or equal to the circle will be a solid, filled in circle.

D is the answer

> multiply the second equation by 2 and add it to the first equation.
2(-6x - 7y = -10)
-12x -14y = -20

8x + 14y = 4
-12x - 14y = -20
--------------------
- 4x + 0 = - 16
x = -16/-4
x = 4

> use x = 4 in either equation to find y
8(4) + 14y = 4
32 + 14y = 4
14y = 4 - 32
14y = -28
y = -28/14
y = -2

8x + 14y = 4 | : 2
-6x - 7y = -10

4x + 7y = 2
-6x - 7y = -10

4x - 6x = 2 - 10
- 2x = - 8
2x = 8

x = 4

8x + 14y = 4

Solve equation for Y and graph it.
5y-x=20

How do I go about solving and graphing this equation.

Answers

So what you first want to do is isolate y.

This could be done by first adding x to both sides:

5y - x + x = 20 + x

5y = x + 20

Then divide everything by 5.

y = 1/5x + 4

Now to graph this equation:

Slope intercept form is y = mx + b.

b would be the y intercept and m the slope.

So therefore you know that 4 is the y intercept.

So first just plot the point (0, 4), and then from there you can take the slope and graph it from there. So basically, the y goes up by 1/5 each time the x goes up by 1. So then you could graph it by looking at where 5 is on the x axis and then graphing one above 4 from there, if that makes any sense.

Let's worry about graphing this first: 5y-x=20

If you set x = 0, then y = 4, and the y-intercept is then (0,4).
If you set y = 0, then x = -20, and the x-intercept is (-20,0).

Plot these 2 pts and then draw a str. line thru them. Done!

If you wish to solve 5y-x=20 for y:

1) add x to both sides: 5y = 20
2) divide both sides by 5: y = 4

How many three-letter "words" can be made from 5 letters "FGHIJ" if repetition of letters is not allowed?

Answers

There are 60 different three-letter "words" that can be made from the letters F, G, H, I, and J without repetition of letters. This can be calculated as a permutation of 5 choices for the first letter multiplied by 4 for the second and 3 for the third, resulting in 5 x 4 x 3 = 60 possible arrangements.

The question asks how many different three-letter "words" can be made from the five distinct letters F, G, H, I, and J, given that repetition of letters is not allowed. This is a problem of calculating permutations, where a permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For each letter position in a three-letter word, we choose a different letter from the five available, without repeating.

For the first letter, there are 5 choices (F, G, H, I, J). Once we have chosen the first letter, there are 4 remaining choices for the second letter. After choosing the first two letters, there are 3 choices left for the third letter. To find the total number of permutations, we multiply these choices together: 5 choices for the first letter x 4 choices for the second letter x 3 choices for the third letter, which equals 60. Therefore, there are 60 different three-letter words that can be made from the letters F, G, H, I, and J without repetition.
