The correct option is: B. length: 14 cm, width: 6.4 cm
<em><u>Explanation</u></em>
The actual length of Lake Superior is 350 miles and the width is 160 miles.
The scale is given as: 1 cm = 25 miles
Suppose, the length and width of the lake on the map are
cm and
cm respectively.
First, the equation according to the <u>ratio of scaled length to the actual length</u> will be....

Now, the equation according to the <u>ratio of scaled width to the actual width</u> will be....

Thus, the length and width of the lake on the map will be 14 cm and 6.4 cm respectively.
(12x5)2+(12x6)2+(6x6)2 will give you the answer. (Subtract 24 from the answer when done)
Answer:
Step-by-step explanation:
Number of blue marbles = 10
Number of white marbles = 7
Number of Red marbles = 6
Number of Green marbles = 2
Total marbles = 10 + 7 + 6 + 2 = 25
Probability of selecting the blue marble = 10/25 = 2/5
