Answer:

2\frac{7}{16}  inches

Step-by-step explanation:

Since 1 mi = 5,280 ft., to convert miles to feet, multiply by 5,280.

96 mi. = 96(5,280 ft.)

96 mi. = 506,880 ft.

Since 1 ft. = 12 in., to convert feet to inches, multiply by 12.

506,,800 ft. = 506,880(12 in.)

506,880 ft. = 6,082,560 in.

The map scale is 1 in. represents 2,500,000 in.

\frac{6,082,560}{2,500,00} = 2.4330...  

The distance on the map between Nanaimo and Campbell River is approximately 2\frac{7}{16}

EACH QUESTION HAS *MULTIPLE* ANSWERS
KIM [24]

Answer:

<u>Associative Property Law</u>

Applies to <em>addition </em>and <em>multiplication </em>only.

Grouping of numbers by parentheses in a different way does not affect their sum or product.

Addition:  (a + b) + c = a + (b + c) = (a + c) + b

Multiplication:  (a × b) × c = a × (b × c) = (a × c) × b

<u>Commutative Property Law</u>

Applies to addition and multiplication only.

Changing the order or position of two numbers does not change the end result.

Addition:  a + b = b + a

Multiplication:  a × b = b × a

<u>Distributive Property</u>

Distributive multiplication over addition and subtraction:

Addition:   a(b + c) = ab + ac

Subtraction:   a(b - c) = ab - ac

<u>Identity Property of Addition</u>

Also known as the <em>identity property of zero</em>.  Adding 0 to any number does not change the number, i.e. the number keeps its identity.

a + 0 = a = 0 + a

<u>Identity Property of Multiplication</u>

Also known as the <em>identity property of one</em>.  Multiplying any number by 1 does not change the number, i.e. the number keeps its identity.

a × 1 = a = 1 × a

1 × 5  identity property of multiplication

5

----------------------------------------------------------------------------------------------

(0 + 3) + 17
