Algebra 2 Word Problem: Set up using 3 variables & 3 equations:
"A friend e-mails you the results of a recent high school swim meet. The e-mail states that 24 individuals placed, earning a combined total of 53 points. First place earned 3 points, second place earned 2 points, and third place earned 1 point. There were as many first-place finishers as second and third-place finishers combined."
A: Write a system of THREE equations that represents how many people finished in each place.
B: How many swimmers finished in first place, second and third?
Final answer:
To solve the word problem, we define three variables representing the number of first-, second-, and third-place finishers, respectively. We set up three linear equations based on the information provided, and by solving the system, we determined that 10 swimmers finished in first place, 8 in second, and 6 in third.
Explanation:
Setting Up the Equations
Let's denote the number of first-place finishers as x, second-place finishers as y, and third-place finishers as z. According to the information provided:
Total number of individuals placed: x + y + z = 24
Total points earned: 3x + 2y + z = 53
The number of first-place finishers equals the number of second and third-place finishers combined: x = y + z
This is our system of three equations.
Solving the System of Equations
To solve for the number of swimmers in each place, use the substitution or elimination method:
Since x = y + z, substitute x in the first two equations.
You'll get two equations with two variables (y and z).
Solve these equations to find the values of y and z.
Finally, substitute the found y and z back into x = y + z to get the value of x.
By solving this system, we find that 10 swimmers finished in first place, 8 swimmers finished in second, and 6 swimmers finished in third.
Can you help me find the value of X?
Answer:
x ≈ 4.1 cm
Step-by-step explanation:
The side (z) opposite the 42° triangle can be found from the relation ...
z/(3.6 cm) = tan(42°)
z = (3.6 cm)·tan(42°) ≈ 3.2415 cm
The relationship between z and x is ...
z/x = cos(38°)
x = z/cos(38°) ≈ 4.1135 cm
x ≈ 4.1 cm
true or false. If f is a function, the f(s+t) = f(s)+f(t). ...?
The statement is true for linear functions, but not in general for all functions.
Explanation:The statement is true if f(x) is a linear function.
However, it is not true in general for all functions, so the statement is false.
An example of a linear function where the statement is true would be f(x) = 2x.
If we substitute s + t into the function, we get f(s + t) = 2(s + t) = 2s + 2t.
On the other hand, if we substitute f(s) + f(t) into the function, we get f(s) + f(t) = 2s + 2t.
Therefore, the equality holds and the statement is true for linear functions.

Bruno uses a piece of wrapping paper with dimensions 1 and 1/4 feet by 3 feet to wrap a gift. What is the total area of the paper used to wrap the gift?
Area is determined by using the formula A=lw Area= Length x Width
A= 1 1/4 x 3 convert to an improper fraction
A= 5/4 x 3/1 multiply
A=15/4 divide
A=3 3/4 square feet
Answer: [tex]A=3\dfrac{3}{4}\ ft^2[/tex]
Step-by-step explanation:
Given: The dimensions of the wrapping paper :
[tex]1\text{ and}\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }1+\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }\dfrac{5}{4}\text{ feet }\text{ by 3 feet}[/tex]
Now, we know that the area of a rectangle is given by :-
[tex]A=length*width[/tex]
Now, the area of the wrapping paper is given by :-

....a. 4.85 ... b. 4.94 ... c. 5.26 ... d. 3.09
Answer:
a. 4.85
Step-by-step explanation:
im right
? = a+b
a = 3
(3+b)/3=3/b
b= -4.85 or 1.85
it cant be negive.
so ? = 3+1.85 = 4.85
A baker bought some flour. he used 2/5 of the flour to make bread and used the rest to make batches of muffins. if he used 16ib. of flour making bread and 2/3ib.for watch batch of muffins,how many batches of muffins did he make?
Answer:
The baker made 36 batches of muffins.
Step-by-step explanation:
Let the total amount of flour be x
We know he used 2/5 of the flour for bread, we also know he used 16 pounds for bread.
We can write this as :
[tex]\frac{2}{5}\times x=16[/tex]
Solving this we get;
[tex]2x=80[/tex]
So, x = 40
Means total amount of flour was 40 pounds and he used 16 pounds for bread, so the remaining is for batches of muffins, which is [tex]40-16=24[/tex] pounds
As each batch of muffin uses 2/3 pounds, so 24 pounds of flour will be used to bake :
[tex]\frac{24}{\frac{2}{3} }[/tex]
= [tex]\frac{24\times3}{2} =36[/tex]
Hence, the baker made 36 batches of muffins.

How are rigid transformations used to justify the SAS congruence theorem?
The method in which rigid transformations used to justify the SAS congruence theorem is given.
What is rigid transformation?A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. In a rigid transformation the pre-image and image are congruent (have the same shape and sizes).
We are given that;
Theorem is SAS
Now,
The SAS congruence theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. To prove this theorem using rigid transformations, we can start with two distinct triangles that have a pair of corresponding congruent sides and a corresponding congruent included angle23. Then we can use a translation to move one triangle so that its congruent side matches the other triangle’s congruent side. Next, we can use a rotation to align the congruent angles of both triangles. Finally, we can use another translation to move the second congruent side of one triangle to match the second congruent side of the other triangle. By doing these rigid transformations, we have shown that one triangle can be mapped onto the other triangle exactly, which means they are congruent
Therefore, by the transformations the answer will be given above.

A cone has a diameter of 10 inches. If its height is twice its radius, about what is the volume of the cone in cubic inches? Use 3.14 for π.
Answer with Step-by-step explanation:
The volume of cone is given by:
V=[tex]\dfrac{1}{3}\times \pi r^2h[/tex]
Where r is the radius of cone and h is height
r=d/2 where d is the diameter
Hence, here r=5 in.
height is twice its radius ⇒ h=10 in.
V=[tex]\dfrac{1}{3}\times 3.14\times 5^2\times 10[/tex]
V=261.66 in³
Hence, Volume of cone is:
261.66 in³
