Question

8 on a blueprint, the scale indicates that 4 centimeters represent 12 feet. what is the length of a room that is 5 centimeters long and 3 1/2 centimeters wide on the blueprint? a. 10.5 feet b. 18 feet c. 15 feet d. 25.5 feet 10 which statement is always true? a an integer is a whole number. b a rational number is a natural number. c a whole number is a natural number. d an integer is a rational number. 2 use the number line below. what is the sum of 5+(-6)+3? a -8 b -1 c 2 d 5

Explanation:

Question 8

Step1: Find the scale factor

The scale is 4 cm represents 12 feet, so the scale - factor is $\frac{12}{4}=3$ feet per centimeter.

Step2: Calculate the actual length

The length on the blueprint is 5 cm. Multiply the blueprint - length by the scale factor: $5\times3 = 15$ feet.

• Integers include positive and negative whole numbers and zero. Whole numbers are non - negative integers (0, 1, 2, ...). Natural numbers are positive integers (1, 2, 3, ...). Rational numbers are numbers that can be written as $\frac{a}{b}$ where $a,b$ are integers and $b

eq0$. An integer $n$ can be written as $\frac{n}{1}$, so it is a rational number.

Step1: Simplify the expression

$5+( - 6)+3=5 - 6+3$. First, $5-6=-1$.

Step2: Add the remaining number

$-1 + 3=2$.

Answer:

C. 15 feet
