1/sqrt8 = 4(m+2)
1/sqrt8 = 4m +8
1 = (4m +8)*sqrt8
1 = 4m*sqrt8 +8sqrt8
sqrt8 = 2sqrt2
1 - 16sqrt2 = (8sqrt2)*m
m = (1 - 16sqrt2)/8sqrt2
m = (1 -16sqrt2)*sqrt2 / (8*2)
m = (sqrt2 -32)/16

The distance between the two schools on the map is (C) 4.2 inches.
<h3>
What is the distance?</h3>
- Distance is a numerical measurement of the distance between two objects or places.
- The distance can refer to a physical length or an estimate based on other criteria in physics or common usage.
- The distance between two points A and B is commonly expressed as |AB|.
To find the distance:
On the map,2 inches represents 5 miles.
Thus, we can write:
- 2 miles = 2 inches
- 1 mile = 2/5 inches ..... (1)
Since the actual distance between the two schools is 10.6 miles.
Multiplying both sides by 10.6 in equation (1).
- 10.6 miles = 10.6 × 2/5 = 21.2/5 = 4.24 inches.
Therefore, the distance between the two schools on the map is (C) 4.2 inches.

The complete question is given below:
Kim is drawing a map of the different schools in her school district. she knows that her middle school is 10.6 miles away from the middle school that her best friend attends. if every 2 inches on the map represents 5 miles, how far apart will the two schools be on the map, to the nearest tenth of an inch?
(A) 0.2 inch
(B) 0.9 inch
(C) 4.2 inches
(D) 26.5 inches
Hello!
The ratio of 1:5
The ratio we are find is 3 : x
We have to find what happened between the ratios
To do this you divide the new number by the old one
3 / 1 = 3
They multiplied the scale by 3 to get the actual wall
Use this to get the length of the wall
3 * 5 = 15
The answer is 15 inches or 1ft 3in
Hope this helps!
Answer:
Step-by-step explanation:
* Lets explain how to solve the problem
- We can write a sine as a cosine by translate the sine function to the
left by
-
∵ The value of sin(0 + π/2) = 1
∵ cos(0) = 1
∴ sin(0 + π/2) = cos(0)
∴ If sin(x) translated to the left by , then it will be
cos(x)
∴
- <u><em>Vice versa</em></u>
- We can write a cosine as a sine by translate the cosine function to
the right by
-
∵ The value of cos(0 - π/2) = 0
∵ sin(0) = 0
∴ cos(0 - π/2) = sin(0)
∴ If cos(x) translated to the right by , then it will be
sin(x)
∴

6 +- 4 is just 6 minus 4. 2
-8 -(-10) would be -8 plus 10. 2
-7 plus 3 would be -4
