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?
To write the price strictly as a decimal, we convert the fraction 9/10 to decimal form. Since 1/10 is equal to 0.1, 9/10 is equal to 9 times 0.1, which is 0.9. Therefore, a gallon of gas costs $3.39 + $0.9 = $<<3.39+0.9=4.29>>4.29. Answer: \boxed{4.29}.
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?
The height of an equilateral triangle is given by the formula: height = side length * √3/2.
Using 74 for the square root of 3, we can approximate the height as follows:
height = 8 * 74/2
= 8 * 37
= 296 meters.
Therefore, the approximate height in meters of an equilateral triangle with a side length of 8 meters is 296 meters.
The height of an equilateral triangle equals 3√/2 times the side length. Using 7/4 for the square root of 3, what is the approximate height in meters of an equilateral triangle with a side length of 8 meters
To find the height of an equilateral triangle, we multiply the side length by the square root of 3 divided by 2.
Given that the side length is 8 meters and using 7/4 as an approximation for the square root of 3, we have:
height = 8 * (7/4) / 2
= 56/8 * 1/2
= 7 * 1/2
= 7/2
Therefore, the approximate height in meters of an equilateral triangle with a side length of 8 meters is 7/2 meters or 3.5 meters.
To convert the price given in dollars and fractions to a decimal, we can simply ignore the fraction part and write the dollar amount as is.
In this case, the price advertised is $3.39 9/10 per gallon. To convert it to a decimal, we ignore the fraction 9/10 and write the dollar amount as $3.39.
Therefore, a gallon of gas costs $3.39 as a decimal.
To convert the price into decimal form, we need to get rid of the fraction.
The fraction 9/10 can be expressed as a decimal by dividing the numerator (9) by the denominator (10).
9 ÷ 10 = 0.9
Therefore, $3.39 9/10 per gallon can be written as $3.39 + $0.90 per gallon.
Adding these two amounts together gives us the total cost of gas per gallon:
$3.39 + $0.90 = $4.29
Therefore, a gallon of gas costs $4.29 when written strictly as a decimal.
