A) Which of the following is true about
-9? (1 point)
• It is both an integer and a whole number.
• It is an integer but not a whole number.
It is an integer but not a rational number.
• It is a whole number but not an integer.
The correct phrase is:
-9 is both an integer and a whole number.
A sign in a gas station advertises gas at the rate of $3.39 9/10 per gallon. How many dollars does a gallon cost, writing the price strictly as a decimal?(1 point)
To convert the price to decimal form, we ignore the fraction part and only consider the whole numbers and decimals.
Therefore, the price of gas per gallon would be $3.39.
Which set of numbers is always rational?
(1 point)
• positive numbers
fractions
decimals
• integers
The set of numbers that is always rational is fractions.
Fractions are defined as the quotient of two integers, where the denominator is not zero. Since fractions can always be expressed as the ratio of two integers, they are always rational numbers.
The height of an equilateral triangle equals 3√2 times the side length. Using 74 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters?(1 point)
Given that the height of an equilateral triangle is equal to 3√2 times the side length, we can substitute the value of √3 as 74 to calculate the approximate height.
Height = 3√2 * side length
Height = 3 * 74 * 2 * 8
Height = 444 * 8
Height = 3552 meters
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 3552 meters.
A) The height of an equilateral triangle equals 13 times the side length. Using
" for the square root of 3, what is the approximate
height in meters of an equilateral triangle with a side length of 8 meters? (1 point)
Given that the height of an equilateral triangle is equal to 13 times the side length, we can calculate the approximate height.
Height = 13 * side length
Height = 13 * 8
Height = 104 meters
Therefore, the approximate height of an equilateral triangle with a side length of 8 meters is 104 meters.
