A scale of 1:125000 means that for any length that is on the map, the real life length is 125000 times as long. This also means that for any length in real life, the length on the map is 1/125000 times as long.

So, a real life length of 10km will be represented by a map length of 10km/125000 = 0.00008km = 8cm

When you have to find the length of map to the actual distance, you will multiply. and if its the other way around as in finding the distance on the map, you will divide. in this case, we will be diving as it is asking the distance on the map.

a scale will always have the unit centimeter, so we will be converting 10km into centimeter.


10km = 1000000cm

1000000/125,000 = 8cm

A and B are two points on square ABCD with coordinates A(1,3) and B(5,3). What are the lengths of the diagonals AC and BD? Round
lilavasa [31]

Answer:

AC = BD = 5.7

Step-by-step explanation:

Given

A = (1,3)

B = (5,3)

Required

The length of the diagonals

First, calculate the length of AB using:

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

So, we have:

AB = \sqrt{(1 - 5)^2 + (3 - 3)^2}

AB = \sqrt{(-4)^2 + 0^2}

AB = \sqrt{16}

AB = 4

The diagonal of a square is calculated using:

Diagonal = x\sqrt{2

Where x is the length of each side.

So:

AC = BD = AB\sqrt{2}

AC = BD = 4\sqrt{2}

AC = BD = 5.7 -- approximated

Karla has spent $42 on food. She bought milk, cheese, and meat. The milk cost half as much as the cheese and the meat cost four
Alina [70]

M = milk

C= cheese

X=meat

milk = 0.5c

meat = 4c

cheese = 1c

<span>4 +0.5 = 1c  = 5.5c</span>

 

C= 42/5.5 = 7.64

X = 7.64 x 4 = 30.56

M =7.64 * 0.5 = 4.67

 

30.56 + 3.82 + 7.64 = approximately $42
