Answer:

<em>D. 69 Km</em>

Step-by-step explanation:

<u>Scaling</u>

Maps usually represent real areas on the field, but since they cannot fit in pieces of paper, we use scales where sizes and distances are all proportional to the real measurements.

On the map of the question, we know 1 cm represents 30 Km. It means that we can know approximate real distances by measuring the distances on the paper or blueprints.

Two cities are 2.3 cm apart on the map, it means that they are really 2.3*30 =69 Km apart

How do I simplify 55/35
Stolb23 [73]

Answer:

1 4/7

Find a number that will divide evenly into both the top number and the bottom number. (You can do any math operation to either number as long as you do the same to the bottom number.)

Keep doing that until you can't find a number that works.

In this case try 5.

55 ÷ 5 = 11 and 35 ÷ 5 = 7

so: 55/35 = 11/7

since the top number is greater than the bottom, reduce 11/7 to 1 4/7

F(x)=2/3x+9x<br> What is the value of f(12)?
andreev551 [17]

Answer:

116

Step-by-step explanation:

To find f(12), plug in 12 as x in the equation:

f(x) = 2/3x + 9x

f(12) = 2/3(12) + 9(12)

f(12) = 8 + 108

= 116

So, f(12) = 116

An LCO Flat Screen TV at Best Buy increased in price from $900 to $1,200. What was the percent of increase?
Roman55 [17]
We can divide the 300 by 900 to get the decimal equivalent of the percentage 300/900 = 1/3 = .33333
multiply that by 100 gives you a percentage of 33.33% increase in mark-up

hope this help
