Ninety students auditioned for the school play. One-third of those who auditioned were cast, 6 in major roles. What fraction of those who were cast got major roles? Write your answer as a decimal.
To find the fraction of those who were cast and got major roles, we need to divide the number of students who got major roles (6) by the total number of students who were cast.
Fraction = (Number of students who got major roles) / (Total number of students who were cast)
Fraction = 6 / (1/3 * 90)
To simplify this expression, we can multiply the numerator and denominator by the reciprocal of 1/3, which is 3/1.
Fraction = (6 * 3) / (1 * 90)
Fraction = 18 / 90
Now, we can simplify the fraction to its lowest terms. Both the numerator and denominator are divisible by 9.
Fraction = 2 / 10
Finally, we can express this fraction as a decimal by dividing the numerator by the denominator.
Fraction = 2 ÷ 10 = 0.2
Therefore, the fraction of those who were cast and got major roles is 0.2.
At Point Pleasant Park, the Advanced Trail is 3.6 times as long as the Medium Trail, and the Medium Trail is 1.2 times as long as the Beginner's Trail. How many times as long as the Beginner’s Trail is the Advanced Trail? Write your answer as a decimal.(1 point)
To find out how many times as long the Advanced Trail is compared to the Beginner's Trail, we need to multiply the lengths of each trail together.
Let's assume the length of the Beginner's Trail is 1 unit.
According to the given information, the Medium Trail is 1.2 times as long as the Beginner's Trail. So, the length of the Medium Trail is 1 * 1.2 = 1.2 units.
Similarly, the Advanced Trail is 3.6 times as long as the Medium Trail. So, the length of the Advanced Trail is 1.2 * 3.6 = 4.32 units.
Therefore, the Advanced Trail is 4.32 times as long as the Beginner's Trail.
So, the answer is 4.32.
here are 7/8
cups of sugar in a canister in the kitchen. Ms. Johnson used 1/2
of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use?(1 point)
To find out how much sugar Ms. Johnson used for the dessert, we need to multiply the fraction of sugar used (1/2) by the total amount of sugar in the canister (7/8 cup).
To multiply fractions, we multiply the numerators together and the denominators together.
Fraction used = (1/2) * (7/8)
Numerator = 1 * 7 = 7
Denominator = 2 * 8 = 16
Fraction used = 7/16
Therefore, Ms. Johnson used 7/16 cup of sugar for the dessert.
How much did Mr. Romanov pay for 9.3 gallons of gas at $3.30 a gallon?(1 point)
$$
To find out how much Mr. Romanov paid for the gas, we need to multiply the number of gallons (9.3) by the cost per gallon ($3.30).
Cost of gas = Number of gallons * Cost per gallon
Cost of gas = 9.3 * $3.30
Cost of gas = $30.69
Therefore, Mr. Romanov paid $30.69 for 9.3 gallons of gas.
One-third of the campers at Rosewood Performing Arts Camp play an instrument. Two-fifths of those campers play the guitar. What fraction of the campers at Rosewood Performing Arts Camp play the guitar?(1 poi
To find the fraction of campers who play the guitar, we need to multiply the fraction of campers who play an instrument (1/3) by the fraction of instrument players who play the guitar (2/5).
Fraction who play the guitar = (1/3) * (2/5)
Numerator = 1 * 2 = 2
Denominator = 3 * 5 = 15
Fraction who play the guitar = 2/15
Therefore, the fraction of campers at Rosewood Performing Arts Camp who play the guitar is 2/15.

not enough information
To find the fraction of the total apples picked that were sold as fresh fruit, we need to subtract the fraction of discarded apples (1/10) and the fraction of apples made into cider from 1 (since the remaining fraction represents the apples sold as fresh fruit).
Fraction sold as fresh fruit = 1 - (1/10) - (300/total apples)
We don't have the total number of apples picked, so we can't determine the exact fraction. Therefore, the answer is "not enough information."

15.96 mi
To solve for the total area of Oak Manor, we need to multiply the length and width together.
Total area = Length * Width
Total area = 3.8 miles * 4.2 miles
Total area = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 mi².

Question
A diver searches for a sunken treasure that is 97.2
feet below the surface. What is the diver's elevation when he is 23 of the way down? (1 point)

negative 64 point 8 ft.
−145.8 ft.
negative 145 point 8 ft.
−48.5
ft.
To find the diver's elevation when he is 23% of the way down, we need to multiply the depth of the treasure (97.2 feet) by 23%.
Elevation = Depth * 23%
Elevation = 97.2 ft * 0.23
Elevation = 22.356 ft
Therefore, the diver's elevation when he is 23% of the way down is approximately 22.356 ft. However, none of the provided answer options match this value, so the correct answer is not listed.
