At a school, 20% of the sixth-grade students are in the band. There are 22 sixth-grade students in the band. How many sixth-graders are in the school?
This is a mathematics problem about percentages. It tells us that 20% of the total number of sixth-grade students equals 22 students who are in the band. By setting up and solving a simple equation, we find that there are 110 sixth-grade students in the school.
Explanation:The subject of your question is Mathematics. This problem is about percentages and can be solved by setting up an equation based on the given information.
It says that 20% which is (0.20 in decimal form) of the total number of sixth-grade students equals the 22 students who are in the band. Let's denote the total number of sixth-grade students by X.
Your equation will look like this: 0.20 × X = 22
To solve for X, divide both sides of the equation by 0.20:
X = 22 / 0.20
Therefore, X = 110.
So, there are 110 sixth-grade students in the school.

You are visiting Washington, D.C. From the American History Museum you walk 5 blocks east and 1 block south to the Air and Space Museum. Then you walk 8 blocks west to the Washington Monument. Where is the Washington Monument in relation to the American History Museum?
Final answer:
The Washington Monument is 3 blocks west of the American History Museum, after making the described movements starting from the museum.
Explanation:
To determine the relative position of the Washington Monument to the American History Museum, let's track the movements step by step. Starting from the American History Museum, if you walk 5 blocks east and then 1 block south, you arrive at the Air and Space Museum. From there, if you walk 8 blocks west, you will reach the Washington Monument.
Now, since you've walked 5 blocks east initially and then 8 blocks back west from the Air and Space Museum, you've ended up 3 blocks west of your starting position at the American History Museum (because 5 - 8 = -3). The 1 block south movement does not affect the east-west positioning. Therefore, the Washington Monument is 3 blocks west of the American History Museum.

a wise man once said 300 reduced by 3 times my age is 114
To solve the equation, assume the person's age is 'x', then translate the sentence into an equation: 300 - 3x = 114. Isolate the variable by subtracting 300 from both sides, then divide both sides by -3 to find 'x'. The person's age is 62.
Explanation:The subject of this question is Mathematics. Specifically, it involves solving an equation to determine the age of the person mentioned in the quote.
To solve the equation, let's assume the person's age is 'x'. Then, we can translate the sentence '300 reduced by 3 times my age is 114' into the equation: 300 - 3x = 114.
To solve for 'x', we can isolate the variable by subtracting 300 from both sides of the equation, giving us -3x = -186. Finally, dividing both sides by -3, we find that x = 62. Therefore, the person's age is 62.

about 3/4 of the students on the track team are girls. about 3/4 of these girls are in grade 8. what fraction on the track team are grade 8 girls?
Given that 3/4 of a track team are girls and 3/4 of these girls are in 8th grade, we can multiply the two fractions to find the fraction of the whole track team that are 8th-grade girls, which is 9/16.
Explanation:The question involves two instances of finding 3/4 of a group. Initially, we are given a track team and we are told that 3/4 of the team are girls. If we let the total number of students in the team equal 1 (or 100%), then the fraction representing the girls is 3/4. Further, 3/4 of these girls are in 8th grade. Therefore, to find the fraction of 8th-grade girls out of the whole team, we multiply the two fractions together as follows: 3/4 * 3/4 = 9/16. This means that 9 out of 16 students are 8th-grade girls, assuming that the track team consists of 16 students. If the track team doesn't consist of 16 students, we can interpret the 9 out of 16 as a ratio.

The fraction of the track team that are grade 8 girls is [tex]\(\frac{9}{16}\)[/tex].
To find the fraction of the track team that are grade 8 girls, we need to multiply the fraction of the team that are girls by the fraction of those girls who are in grade 8.
Let's denote the total number of students on the track team as [tex]\(T\)[/tex]. According to the information given:
- About[tex]\(\frac{3}{4}\)[/tex] of the students on the track team are girls. So the number of girls on the track team is [tex]\(\frac{3}{4}T\)[/tex].
- About [tex]\(\frac{3}{4}\)[/tex] of these girls are in grade 8. Therefore, the number of grade 8 girls is [tex]\(\frac{3}{4} \times \frac{3}{4}T = \frac{9}{16}T\)[/tex].
Thus, the fraction of the track team that are grade 8 girls is [tex]\(\frac{9}{16}\)[/tex]. This is found by dividing the number of grade 8 girls by the total number of students on the track team:
[tex]\[ \frac{\text{Number of grade 8 girls}}{\text{Total number of students on the track team}} = \frac{\frac{9}{16}T}{T} = \frac{9}{16} \][/tex]
Therefore, the fraction of the track team that consists of grade 8 girls is[tex]\(\frac{9}{16}\)[/tex].

A gallon of gasoline costs $2.96 your car has a 25- gallon gas tank and can travel 28.8 miles one each gallon of gasoline find the cost of filling your gas tank if it’s already 3/8 full
To find the cost of filling the gas tank, calculate the empty part of the tank, which is 5/8 of 25 gallons. Then multiply that by the cost of a gallon of gasoline, which gives you $46.25.
Explanation:To solve this problem, we need to calculate how much gasoline is needed to fill up the car's tank considering that it's already 3/8 full and then multiply that by the cost of gasoline per gallon.
Firstly, we need to find out how much of the tank's capacity is empty. The tank has a total capacity of 25 gallons and 3/8 of it is already full. This means 5/8 of the tank is empty. The empty capacity is 5/8 * 25 = 15.625 gallons.
Given that a gallon of gasoline costs $2.96, we need to multiply the cost per gallon by the number of gallons needed. Therefore, the cost to fill the tank equals to 2.96 * 15.625 = $46.25.
