damon kayaks on a river near his home. he plans to kayak a total of 6.4 miles. Damon kayaks at an average speed of 1.6 miles per hour. How many hours will it take Damon to kayak the 6.4 miles?

Answers

The answer to your problem is 4 hours

Damon will need 4 hours to kayak 6.4 miles on the river near his home, given his average speed of 1.6 miles per hour.

To calculate how many hours it will take Damon to kayak a total of 6.4 miles if his average kayaking speed is 1.6 miles per hour. To solve this, we can use the formula for time which is distance divided by speed. In this case, the distance is 6.4 miles and the speed is 1.6 miles per hour. Therefore:

Time = Distance \/ Speed = 6.4 miles \/ 1.6 miles per hour = 4 hours.

It will take Damon a total of 4 hours to kayak the 6.4 miles on the river near his home.

Line m passes through the points (6,1) and (2,-3). Line n passes through the points (2,3) and (5,-6). Find the point intersection of these lines.

Answers

Since we know that m and n are lines, we can put these points into equations (slope-intercept form would be easiest), and then set the equations equal to each other to see what their x coordinate is when they intersect. 

For (6,1) and (2,-3):
slope = (y2 - y1) / (x2 - x1) = (-3 - 1) / (2 - 6) = -4 / -4 = 1

plugging this into slope-intercept form:
y = mx + b
1 = 1 x 6 + b
1 = 6 + b
b = -5
So our equation in slope intercept form is:
y = x -5

Taking the same steps for line n, we find that it's slope-intercept form is:
y = -3x + 9

If we set these two equations equal to each other, we can find the x-coordinate of the point of intersection:
-3x + 9 = x - 5
14 = 4x
x = 3.5

Plugging 3.5 back into to one of our original equations will give us the y coordinate of intersection:
y = x - 5
y = 3.5 - 5 = -1.5

Therefore, the point of intersection is (3.5, -1.5)

The point of intersection for lines (m) and (n) is (3.5, -1.5). Line (m) equation: (y = x - 5). Line (n) equation: (y = -3x + 9).

To find the point of intersection of two lines, you can use the point-slope form of a line and set the equations of the lines equal to each other. Let's first find the equations of the lines ( m ) and ( n ) using the given points.

Line ( m ) passes through the points ( (6,1) ) and ( (2,-3) ). Let's find the slope of line ( m ) first:

[tex]\[ \text{Slope of } m = \frac{{y_2 - y_1}}{{x_2 - x_1}} \][/tex]

[tex]\[ \text{Slope of } m = \frac{{-3 - 1}}{{2 - 6}} = \frac{{-4}}{{-4}} = 1 \][/tex]

Now we can use the point-slope form of a line to find the equation of line ( m ):

y - y_1 = m(x - x_1)

Let's use the point ( (6,1) ) to find the equation of line ( m ):

y - 1 = 1(x - 6)

y - 1 = x - 6

y = x - 6 + 1

y = x - 5

So, the equation of line ( m ) is ( y = x - 5 ).

Now let's find the equation of line (m and  n) passing through the points

( (2,3) ) and ( (5,-6) ):

[tex]\[ \text{Slope of } n = \frac{{-6 - 3}}{{5 - 2}} = \frac{{-9}}{{3}} = -3 \][/tex]

Using the point ( (2,3) ) to find the equation of line ( n ):

y - 3 = -3(x - 2)

y - 3 = -3x + 6

y = -3x + 6 + 3

y = -3x + 9

So, the equation of line ( n ) is ( y = -3x + 9 ).

Now, we'll set the equations of ( m ) and ( n ) equal to each other to find the point of intersection:

x - 5 = -3x + 9

Now, solve for ( x ):

x + 3x = 9 + 5

4x = 14

[tex]\[ x = \frac{{14}}{4} \][/tex]

x = 3.5

Now, substitute ( x = 3.5 ) into either equation to find ( y ). Let's use the equation of line ( m ):

y = 3.5 - 5

y = -1.5

So, the point of intersection of lines ( m ) and ( n ) is ( (3.5, -1.5) ).

The product of r and 9 divided by 2 is equal to 27 what is the value of r?

Answers

Answer: r = 6

Step-by-step explanation: We would start by making an equation for this which would be 9r / 2 = 27. We need to get r by itself so we first multiply 2 on both sides by 2 to get rid of that pesky 2.

[tex]\frac{9r}{2}[/tex] * 2 = 27 * 2

9r = 54

Now we have to get rid of the 9 and since this is multiplication, we have to divide 9 on both sides.

[tex]\frac{9r}{9}[/tex] = [tex]\frac{54}{9}[/tex]

This would give us r = 6.

The value of r is found by setting up an equation from the given statement, solving which gives r = 6.

To solve for the value of r when the product of r and 9 divided by 2 is equal to 27, we can set up the following equation: (r  imes 9) / 2 = 27. Multiplying both sides by 2 to eliminate the denominator gives us r  imes 9 = 54. We then divide both sides by 9 to solve for r, resulting in r = 6.

Tommy goes out for lunch and he can choose a hamburger, grilled cheese, a hot dog, or pizza. Tommy also has the choice of french fries , fruit or applesauce for his side. For his drink, Tommy can have milk, juice, or soda. How many different combinations can Tommy create for his lunch.

Answers

12 combinations, reason being, you have to match up each main dish with a side dish and the drink. For example. Hamburger, fries, juice. Grilled cheese, fries, juice, etc.

To calculate the total lunch combinations Tommy can create, we multiply his options for main dish (4), side (3), and drink (3), resulting in 36 different combinations. Making healthier choices, like water over soda or smaller portions, supports long-term health.

When considering the various combinations Tommy can create for his lunch, we employ the fundamental counting principle. This principle states that if there are 'n' ways to do one thing, and 'm' ways to do another, then there are n*m ways to do both. Applying this to Tommy's choices:

He has 4 options for the main dish (hamburger, grilled cheese, hot dog, or pizza),3 options for the side dish (french fries, fruit, or applesauce), and3 options for the drink (milk, juice, or soda).

To find the total number of different lunch combinations Tommy can create, we multiply the number of choices for each category:

Total combinations = 4 mains * 3 sides * 3 drinks = 36 different combinations.

When making food choices, the keys to healthy eating include knowing what you're consuming and selecting options that contribute to long-term health. Opting for nutrient-dense foods over calorie-rich and nutrient-poor choices is important. For example, selecting water instead of soda, a smaller portion of fries, or adding a piece of fruit can make a significant difference in calorie intake and nutritional value.

By choosing grilled chicken over fried items, and being cautious of high-calorie dressings and sauces, it's possible to find healthier options even when dining out. The overall goal is to make informed decisions that support a healthy lifestyle.

what integer describes a profit of $300

Answers

+300 Good luck with other questions!

Final answer:

The integer representing a profit of $300 is the positive integer 300.

Explanation:

The integer that describes a profit of $300 is simply 300. In the context of economics and mathematics, profits and losses are represented as positive and negative integers respectively. In this scenario, since we are speaking of a profit, the integer is positive. If you were incurring a loss of $300, then the integer would be -300. Additionally, considering aspects of business calculation provided in the reference information, an increasing profit or a decreasing profit due to changes in advertising costs or quantity sold can affect the calculation of profit; however, the specific answer to your question remains 300.

January 10, 2007 by Janbowier

When the number in the numerator of a unit rate is 1, it indicates that the unit rate is equivalent to the value of the denominator alone. In other words, it signifies that the quantity being measured is directly proportional to the value of the denominator.

For example, consider a unit rate of "1 mile per hour." Here, the numerator (1 mile) indicates that for every 1 unit of the denominator (1 hour), the distance covered is 1 mile. So, if a car travels at a speed of 1 mile per hour, it means the car covers a distance of 1 mile in 1 hour.

Similarly, let's say we have a unit rate of "1 gallon per minute" for the flow rate of water from a faucet. This implies that for every 1 unit of time (1 minute), the faucet dispenses 1 gallon of water. Therefore, if the faucet runs at a rate of 1 gallon per minute, it means it releases 1 gallon of water every minute.

In summary, when the numerator of a unit rate is 1, it indicates a direct relationship between the quantity being measured and the value of the denominator alone. This relationship simplifies the understanding of the unit rate and its application in various contexts.

Explain how you can use doubles when multiplying with4 to find 4x8?

Answers

using 4x6=24. double the factor four to get eight double the factor 24 to get 48
Final answer:

To multiply 4 by 8 using doubles, you double the numbers sequentially (4 to 8, 8 to 16, 16 to 32) to reach the desired result of 32. Moreover, when comparing the area of two squares, where one has a side length that is double the other, the area of the larger square is four times that of the smaller square.

Explanation:

To multiply 4 by 8 using doubles, you can double 4 to get 8, and then double 8 to get 16, and then double again to get 32. So essentially, you've found that 4 x 2 = 8, then took that result and found 8 x 2 = 16, and finally, you took that result and found 16 x 2 = 32, which is the same as 4 x 8. This method of doubling allows you to use simpler multiplication facts you may already know well, like multiplying by 2, to find the answer to more complicated problems.

In the context of scale factors and area comparisons, if you have a square with a side of 4 inches, and another square with sides twice as long (4 inches x 2 = 8 inches), the area of the second square would be 8 inches x 8 inches, which is 64 square inches. Compared to the first square, which has an area of 4 inches x 4 inches (16 square inches), the second square is larger by a factor of four (64 / 16 = 4). This demonstrates how the area increases by the square of the scale factor, not just by the scale factor itself.

Given:

A Chemist has 100 g of 25% acid solution.

Let : The mass of the solution that need to be drained = x grams

[tex]\texttt{mass of acid from 25\% solution} = m_1 = 25\% \times (100-x) \texttt{ g}[/tex]

[tex]\texttt{ }[/tex]

x grams of 70% acid solution is added.

[tex]\texttt{mass of acid from 70\% solution} = m_2 = (70\% \times x) \texttt{ g}[/tex]

[tex]\texttt{ }[/tex]

Final solution → 100 g of 60% acid solution

[tex]\texttt{total mass of acid} = m_1 + m_2[/tex]

[tex]60\% \times 100 = (25\% \times (100-x)) + (70\% \times x)[/tex]

[tex]60 = 25 - 25\%x + 70\%x[/tex]

[tex]60 - 25 = 45\%x[/tex]
