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].
When light energy meets the surface of your sunglasses, what is the evidence that some of it has been: transmitted, reflected and absorbed?
When light energy meets the surface of sunglasses, some of it is transmitted, some are reflected, and some are absorbed.
What is light energy?Light energy is a form of electromagnetic radiation that is visible to the human eye.
It is a type of kinetic energy that travels in the form of waves at a speed of 299,792,458 meters per second in a vacuum.
We have,
The evidence that light has been transmitted through your sunglasses is that you can see through them.
The amount of light that is transmitted depends on the type of sunglasses and the properties of the lens material.
Sunglasses with darker lenses will transmit less light than those with lighter lenses.
The evidence that light has been reflected is that you can sometimes see reflections on the surface of your sunglasses.
This can be from the front surface of the lens or the back surface, depending on the design of the sunglasses.
Reflected light can also cause glare, which is why many sunglasses have anti-reflective coatings.
The evidence that light has been absorbed is that the lens of your sunglasses appears to be a different color.
The color of the lens is determined by the type of material used and the specific dyes or pigments added to the lens during manufacturing.
Different colors of lenses are designed to absorb different wavelengths of light, which can be useful for different activities such as driving or skiing.
Overall, the combination of transmission, reflection, and absorption of light in sunglasses helps to reduce the amount of light that reaches your eyes and can improve your visual comfort and clarity in bright environments.
Thus,
When light energy meets the surface of sunglasses, some of it is transmitted, some are reflected, and some are absorbed.

At a store, 4 pairs of pants cost $90.00 and 4 pairs of jeans cost $78.00. How much would it cost to buy 3 pairs of pants and 5 pairs of jeans?
Final answer:
To calculate the total cost, find the individual costs of the pants and jeans, multiply them by the required quantity, and sum the resulting amounts. It costs $165.00 to buy 3 pairs of pants and 5 pairs of jeans.
Explanation:
To calculate the cost of buying 3 pairs of pants and 5 pairs of jeans, we first need to find the cost of one pair of pants and one pair of jeans. Given that 4 pairs of pants cost $90.00, the price per pair of pants is $90.00 ÷ 4 which equals $22.50. Similarly, 4 pairs of jeans cost $78.00, so the price per pair of jeans is $78.00 ÷ 4 which equals $19.50.
We then multiply the cost per pair of pants by the number of pants we want to buy, which is 3, and do the same for the jeans by multiplying the cost per pair by 5. Therefore, the total cost for the pants is 3 × $22.50 = $67.50, and the total cost for the jeans is 5 × $19.50 = $97.50.
Finally, we add these two amounts together to get the total cost: $67.50 + $97.50 = $165.00. So, it would cost $165.00 to buy 3 pairs of pants and 5 pairs of jeans.

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.
