What is the unit cost per pears? Write an equation.
Does this relationship represent a proportional relationship? Use a graph to prove it. Explain how the graph proves the situation is a proportional relationship.
Answers
Answer:
see the explanation
Step-by-step explanation:
The correct question is
Sean wrote the equation 9.25=5m, where m is the cost per pound, to show the relationships between the total cost, $9.25, and the number of pounds of pears, write an equation to show the cost y of x pounds of pears, and use the equation to complete the table. then use the information in your table to make a graph
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
y ----> the total cost
x ---> the number of pounds of pears
In this problem we have a proportional relationship between the variables x and y
we have
[tex]9.25=5m[/tex]
where
m is the cost per pound of pears
That means
The value of m and the value of the constant k of proportionality is the same
Find the value of m
[tex]9.25=5m\\m=\$1.85\ per\ pound[/tex]
The linear equation is equal to
[tex]y=1.85x[/tex]
Construct the table
assume different values of x and determine the value of y
[tex]For\ x=0 ----> y=1.85(0)=0[/tex]
[tex]For\ x=1 ----> y=1.85(1)=1.85[/tex]
[tex]For\ x=2 ----> y=1.85(2)=3.70[/tex]
[tex]For\ x=3 ----> y=1.85(3)=5.55[/tex]
[tex]For\ x=4 ----> y=1.85(4)=7.4[/tex]
[tex]For\ x=5 ----> y=1.85(5)=9.25[/tex]
therefore
[tex]\begin{array}{cc}x(\text{Number of pounds}) & y(\text{Cost in dollars})\\0 & 0\\1 & 1.85\\2 & 3.7\\3 & 5.55\\4 & 7.4\\5 & 9.25\end{array}[/tex]
using a graphing tool
The grahp in the attached figure
Final answer:
The unit cost per pound of pears is $1.85, found by dividing the total cost ($9.25) by the number of pounds (5). This represents a proportional relationship, as the graph of the equation y = 5x is a straight line through the origin, showing a constant ratio of total cost to pounds of pears.
Explanation:
The question regarding the equation 9.25 = 5m asks us to find the unit cost per pound of pears and determine whether the relationship represents a proportional relationship. To find the cost per pound, we simply need to divide both sides of the equation by 5. This gives us m = 9.25 / 5, which calculates to m = $1.85. Therefore, the unit cost per pound of pears is $1.85.
To test for a proportional relationship, we can graph the equation y = 5x, where 'y' is the total cost and 'x' is the number of pounds of pears. A proportional relationship is one where the ratio of y to x is constant, and the graph is a straight line through the origin. Since our equation represents a linear relationship that passes through the origin (0,0), it confirms that this is, indeed, a proportional relationship. The graph would show a straight line with a slope of 5, indicating that for every increase of 1 pound of pears, the cost increases by $5.
For the triangle shown, describe which sides are the legs and which are the hypotenuse. Explain how you know.
Answers
Answer:
legs: a and b
hypotenuse: c
Step-by-step explanation:
The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse.
Answer:
a and b are the legs, and c is the hypotenuse
Step-by-step explanation:
The legs of a right triangle are always the sides that form the right angle. Looking at the picture, we see that at one corner of the triangle, there's a little square. Remember that this little square always denotes an angle with degree 90, which means this is the right angle. Then, since sides a and b form this angle, we know that a and b are the legs.
Another thing to remember is that the hypotenuse of a right triangle is the side that lies opposite to the right angle. Here, you can see that side c lies opposite to the right angle, so we know it's the hypotenuse.

pen needs to be rectangular in shape however it will be built along a river side of the pen that does not need to be fenced. The farmer has a total of 700 feet of fence to build the pen. Determine the dimensions that will maximize area of the pen
Answers
Answer: The dimensions that will maximize area of the pen are 350 ft by 175 ft
Step-by-step explanation: The farmer has a total of 700 feet of fence for a rectangular pen which is in effect the perimeter. However, one side is by the river and would not need to be fenced. Hence we can determine that the perimeter would cover three sides only.
This means the sides would be in the ratio of 2 : 1 : 1
Hence, one side would be 2/4 and the other two sides would be 1/4 each
For the whole 700 meters of fencing, the sides can be calcualted as follows;
Length = 2/4 x 700
Length = 350
Width = 1/4 x 700
Width = 175
Therefore, with the length of fence available, the dimensions for the rectangular pen would be
Length = 350 ft
Width = 175 ft

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1,017.36 square feet use 3.14 for pi
Answers
Answer:
18
Step-by-step explanation:
1,017.36 is the area of the circle and you need to find the radius
area formula : 3.14rsquared
so the formula you are going to solve for your answer is 3.14rsquared=1,017.36
divide by 3.14
rsquared = 324
un square it to get you radius which is 18
you didnt clarify whether you wanted radisu or diameter so ill give both
R: 18
D:36
Answer:
The sprinkler can spread water up to 36 feet away!
Step-by-step explanation:
First, identify the formula used to find the area of a circle:
Area = pi x r^2
We already know the area that the sprinkler makes, so just plug that in! Then, we just need to reverse engineer the formula!
1,017.36 square feet = pi x r^2
1,017.36 square feet= 3.14 x r^2
1,017.36/3.14 = r^2
324 = r^2
sqrt of 324 = 18
So, we figured out that the radius of the circle is 18 feet! Now, remember the radius is just half the amount of the diameter!
18 x 2 = 36 feet

tom and adam have a total of 240 stamps.The ratio of the number of tom's stamps to adam's is 3:7.Tom buys some stamps from Adam.The ratio of tom's stamp to adam's is now 3:5.How many stamps does tom buy from adam
Answers
Answer:
18
Step-by-step explanation:
In both cases, the number remains constant, 240 stamps.
Given that 3:7 is equal to 3/10 to 7/10
Initially, Tom had 3/10*240=72 stamps
Finally, 3:5 equal to 3/8 to 5/8
Tom has 3/8*240=90 stamps
Difference is 90-72=18 stamps
Therefore, Tom bought 18 stamps from Adam and Adam didn't replace
Given the initial and new ratios of Tom's and Adam's stamps, and the total number of stamps they have, we can setup and solve an equation which reveals that Tom bought 48 stamps from Adam.
Explanation:This math question involves the concept of ratios and some algebra. Given that Tom and Adam initially had a total of 240 stamps between them in a ratio of 3:7, we can divide 240 by the total parts of their ratio (3 + 7 = 10 parts). So, one 'part' is 240 divided by 10, which equals 24.
Therefore, Tom initially had 3 parts i.e., 3*24 = 72 stamps while Adam had 7 parts i.e., 7*24 = 168 stamps.
After Tom buys some stamps from Adam, their ratio changes to 3:5. Let's denote the number of stamps Tom bought as x. Then, Tom would have 72 + x stamps, while Adam would have 168 - x stamps.
Since their ratio is now 3:5, we can set up an equation represented by (72 + x) / (168 - x) = 3 / 5. Solving this equation gives us x = 48.
So, Tom bought 48 stamps from Adam.

For the high school basketball game, it costs $8 for every 4 tickets.
Complete the table below showing the cost and the number of tickets.

Answer:

Step-by-step explanation:

---------------------------------------------------------------------------
4 8 12 16 20 24 28 32 36 40
Final answer:
The question is about calculating the costs associated with purchasing tickets, given a known rate of $8 for every 4 tickets. Using the formula cost equals 2 times the number of tickets, one can calculate the total cost for any number of tickets, maintaining a direct proportionality.
Explanation:
Finding Costs Based on Ticket Quantities
To determine the cost for a varying number of tickets given the rate of $8 for every 4 tickets, we can set up a proportional relationship where the cost (C) is related to the number of tickets (T) by the constant of proportionality 8/4, or 2. Therefore, C = 2T, which means that the cost is simply twice the number of tickets because 8 dollars are charged for every 4 tickets.
We can fill out the table using the formula C = 2T, where C represents the total cost and T represents the number of tickets:
For 4 tickets: C = 2(4) = $8
For 8 tickets (twice the initial quantity): C = 2(8) = $16
And so on, for each additional set of 4 tickets, we add another $8 to the cost.
If we were to complete the hypothetical table, for each additional 4 tickets, we would add $8 to the total cost, maintaining this direct proportionality.
While solving an equation for x lewis is left with the equation 2=4. Explain why lewis can be certain that the equation does not have a solution

Final answer:
Lewis can be certain there is no solution to the equation because ending up with '2=4' is a contradiction, and two distinct constants cannot be equal.
Explanation:
When solving an equation, if you simplify all the expressions and end up with a statement such as 2=4, this indicates that the equation does not have a solution. This situation is also known as a contradiction because 2 and 4 are distinct constants and cannot be equal. A step-by-step approach might include starting from the original equation, performing algebraic manipulations, and then arriving at an absurd conclusion, which tells us the equation has no solution.
In contrast, when solving quadratic equations, such as x² = 4, you might get valid solutions like √4=±2, which indicate a solution set of {-2, 2}. However, if your result contradicts a fundamental truth, like the equality 2=4, it's clear that the equation has no feasible solution within the realm of real numbers.
