The distance between the baseball stadium and the airport is 1.6x10^6 centimeters. Which unit of measurement is most appropriate to measure the distance. ( i need to
Get this right or i will fail)
A. Inches
B. Milimeters
C. Kilometers
D.feet

Answers

Answer 1
C. Kilometers People like to deal with measurements using numbers close to 1. The closer, the better. But we're not talking about absolute values. We're talking about how many leading or trailing zeros we have to deal with. 0.000000001 is just as bad as 1000000000. So let's look at the choices and see what fits best. A. Inches * This is slightly better than the 1.6 million centimeters, but is 630 thousand inches all that much better? I don't think so. B. Millimeters OK, instead of 1.6 million centimeters, we'll use 16 million millimeters. Looks like we're going the wrong way here. C. Kilometers Hmm. Instead of 1.6 million centimeters, we get 16 kilometers. That's a nice small number. Looks good. D. feet How does 52.5 thousand sound to you? Not so great. So this is another bad choice. Of the 4 choices, only kilometers is reasonable. The other units of measurement are way too small. The kilometer is approximately the same scale as the distance to be measured (distance from baseball stadium to the airport). And because it's an appropriate scale, the result is a number that's fairly close to 1. When you start measuring really small things, then units like centimeters, millimeters, or even nano-meters make sense. And going the opposite direction, when measuring long distances, things like light seconds, or light years make sense. Use the scale that closest to what you're measuring.

imma go with the answer choice C.) because it has no repeats

Can someone check this please

Answers

Let's check the answer

Start with equation (1). Plug in (x,y) = (-10,-1)
x + 5y = -15
-10 + 5y = -15 ... replace x with -10
-10 + 5(-1) = -15 ... replace y with -1
-10 - 5 = -15
-15 = -15 ... true equation

So we've confirmed one equation so far. Let's check the other equation

--------------------

Start with equation (2). Plug in (x,y) = (-10,-1)

y = (1/5)*x + 1
y = (1/5)*(-10) + 1 ... replace x with -10
-1 = (1/5)*(-10) + 1 ... replace y with -1
-1 = -2 + 1
-1 = -1

Since both equations are true when (x,y) = (-10,-1), this confirms the answer. Nice work on getting the correct answer.

Visually we can see the two lines crossing at (-10,-1). See the attached image. Note: 1/5 = 0.2 so the second equation can be written as y = 0.2x+1

Suppose that 5 customers arrive, and each orders a different appetizer to share from a choice of 12 appetizers. In how many ways can this be done?

Answers

Final answer:

The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers is 95,040.

Explanation:

The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers can be calculated using permutations. In this case, the order in which the appetizers are chosen does matter, and repetition is not allowed since each customer must choose a different appetizer.

To calculate the number of ways, we can use the formula for permutations:

P(n, r) = n! / (n-r)!

Where n is the total number of items and r is the number of items to be chosen.

So, in this case, the number of ways to choose the appetizers is:

P(12, 5) = 12! / (12-5)! = 12! / 7!

Using a calculator simplifies to:

P(12, 5) = 95,040

Answers

The problem describes an angle like the one in the picture attached.

The vertex point is H, and G and K are 2 points on the 2 rays.


The way we name such angles, is by using the 3 letters, always letting the vertex point H in the middle. The order of the 2 other letters is not important.

Another way to name the angle is by using only the letter of the vertex point.

So

We can name the angle ∠GHK, ∠KHG or ∠H.

Answer: ∠GHK, ∠KHG or ∠H.

Angle GHK and Angle H

write each ratio as fraction in simplest form. Then explain it 2 drums, 4 flutes

Answers

When you report it as a ratio, you write it as a:b. This could also be reported as a fraction as a/b. Ratios and fractions are just the same in concept, which shows the relative amounts of the components. For example, if you want to find the ratio of drums to flutes, that would be 2/4 in fraction form. Since 2 and 4 are multiples of each other, we can simplify it further to 1/2.

James says that 12 is a common factor of 3 and 4.june says that 12 is common multiple of 3 and 4.who is correct.

Answers

June is correct because 12 is a multiple of both 3 and 4.
June is correct. 

When you are dealing with factors, you have to think of what numbers multiply to get the number I see.
Let's say the number is 10. What numbers can be multiplied to get 10.
Well, there is 1, 10, 2, 5 so all of those numbers are factors of 10.

When you are dealing with multiples, you have to think of the opposite. If the question asks is 12 a multiple of 3 and 4, than you have to think...If I multiply a number by 3 could I get 12 and... If I multiply a number by 4 could I get 12. The answer is yes you could multiply 3 and 4 and 4 and 3 to get the number 12. That makes 12 a multiple.  

After a 85% reduction, you purchase a new soft drink machine for $90. What was the original price?

Answers

Final answer:

The original price of the soft drink machine was $600, obtained by using the percentage reduction formula to find that $90 represents 15% of the original price.

Explanation:

To find the original price of the soft drink machine before the 85% reduction, we first need to understand what a percentage reduction means. An 85% reduction implies that the final price is only 15% of the original price, as 100% - 85% = 15%. Therefore, the $90 you paid is 15% of the original price.

Next, we will step through the following calculation to determine the original price:

Let the original price be represented by P.15% of P is equal to $90, which can be written as (15/100) × P = $90.To find P, we divide both sides of the equation by 15 and then multiply by 100 to isolate P on one side. This gives us P = (90 ÷ 15) × 100.Performing the calculation P = 6 × 100, we find that P = $600.

Therefore, the original price of the soft drink machine was $600.

Rearrange to
3L^2 (squared)- 16L- 35= 0 
L=7
W=5
Final answer:

The dimensions of the rectangle are approximately 8.93 feet for the length and 10.8 feet for the width. This solution involves setting up and solving a quadratic equation based on the given conditions.

Explanation:

The subject of this question is Mathematics and it requires algebraic reasoning to solve. Here's step-by-step how to find the dimensions of the rectangle:

Let the length be denoted by 'x' (in feet).According to the question, the width is 16 feet less than three times the length, which can be written algebraically as '3x - 16'.The area of a rectangle is calculated by length times width, so in this example we would multiply 'x' by '3x - 16', and set that equal to the total area of 35 square feet.This set-up results in the equation 'x(3x - 16) = 35' or '3x^2 - 16x - 35 = 0'.Solving this quadratic equation for 'x', we find that the length (x) is approximately 8.93 feet.Substituting this value back into the equation for width, we find that the width is approximately 10.8 feet.

Each Child Receives a meal which consists of a hamburger, a bag of pretzels, and a drink for the children ages 6-10 and a hamburger , two bags of pretzels, and a drink for the children that are older than 10. It costs the club 80 cents for each hamburger, 35 cents for each bag of pretzels, and 60 cents for each drink. Calculate the cost to feed each age group

Answers

The cost and answer for all of the foods are $34.76
Since there isn't a given amount of children for both age groups you can represent each group by a variable:

Let variable (a) stand for the number of children ages 6-10.

Let variable (b) stand for the number of children ages 10 and older.

For one child of age 6-10, the total of the sum of the costs of each food item given to him or her would be $1.75

For one child of age 10 or older, the total of the sum of the costs of each food item given to him or her would be $2.10

The total cost to feed children 6-10 can be represented as an equation:
Total cost = 1.75a

The total cost to feed children 10 or older represented as an equation would be:
Total cost = 2.1b

And if you were to find the two total costs of both groups combined the equation would look like this:
Total cost = 1.75a + 2.1b
