kiran is spending $12 on games and rides at a carnival where a game costs $0.25 and a ride cots $1.
Which graph represents the relationship between the quantities in this situation?
It's C or A if it's C that's right if it's A I'm wrong be pretty sure it is C
Graph C is the correct alternative as it can be seen from the equation y = - 0.25x + 12 that the graph will have negative slope and will have a linear relationship with x.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Kiren is spending $12 on games and rides at a carnival where a game costs $0.25 and a ride costs $1.
Assume that Kiren played 'x' games and rides 'y' times.
Total amount with Kiren = A[T] = $12
Cost of game = A[G] = $0.25
Cost of ride = A[R] = $1
Then we can write a equation representing above scenario as -
A[T] = A[G]x + A[R]y
0.25x + y = 12
y = - 0.25x + 12
It can be seen that the graph will have negative slope and will have a linear relationship with x. Hence, graph C is correct.
Therefore, Graph C is the correct alternative as it can be seen from the equation y = - 0.25x + 12 that the graph will have negative slope and will have a linear relationship with x.

Step-by-step explanation:
Here is the complete question
An ambulance require diesel as fuel because of so many trips nearby pump purchase diesel in bulk for the ambulance there are three containers at the pump which contain 403 L 434 L and 465 L of diesel respectively the maximum capacity of measuring container that can be measured the diesel of the three containers an exact number of times is
Solution
To find the exact number of times in which we can measure the diesel in the three containers, since the capacity of each container is 403 L, 434 L and 465 L respectively, we find the prime factors of each number.
The prime factors of 403 = 13 × 31
The prime factors of 434 = 2 × 7 × 31
The prime factors of 465 = 3 × 5 × 31
The measuring capacity equals the highest common factor (H.C.F) of the three numbers. That is H.C.F of 403, 434, 465.
Since it can be seen here that the H.C.F is 31, then the maximum capacity of measuring container that can be measured the diesel of the three containers an exact number of times is 31 L

Consider the triangle below.
Need help ASAP.....
Answer: See below
Step-by-step explanation:
For part a, we are given that the triangle is an isosceles triangle. That means the two sides that are marked are equal to each other. We set DE and EF equal to each other to find x.
5x-3=3x+7 [subtract both sides by 3x]
2x-3=7 [add both sides by 3]
2x=10 [divide both sides by 2]
x=5
We now know the value of x is 5.
For part b, all we have to do is plug in x=5 to find the length of each leg.
5(5)-3 [multiply]
25-3 [subtract]
DE=22 in
3(5)+7 [multiply]
15+7 [add]
EF=22 in
Now, we have the length of each leg. DE=22 in, EF=22 in
For part c, we do the same as above and plug in x=5 to find the length of the base.
6(5)-3 [multiply]
30-3 [subtract]
DF=27 in
Now, we have the length of the base. DF=27 in

Work Shown:
Corresponding angles are congruent when we have parallel lines.
5x-10 = 2x+20
5x-2x = 20+10
3x = 30
x = 30/3
x = 10
-------------------------
5x-10 = 5*10-10 = 50-10 = 40
2x+20 = 2*10+20 = 20+20 = 40
Each angle is 40 degrees, which helps confirm our answer.

C4 Let B = {₁,...,V) be a set of vectors in R". Prove that if v₁ = Ổ for some i, then B is linearly dependent.
In this question, we are given a set of vectors B in [tex]R_{n}[/tex] and we need to prove that if there exists a vector v_i in B such that v_i is the zero vector, then the set B is linearly dependent.
To prove that if v_i is the zero vector for some i, then the set B is linearly dependent, we need to show that there exist scalars c_1, c_2, ..., c_n (not all zero) such that the linear combination c_1v_1 + c_2v_2 + ... + c_nv_n equals the zero vector.
Since v_i is the zero vector, we can choose c_i = 1 and c_j = 0 for j ≠ i. Then, the linear combination becomes c_1v_1 + c_2v_2 + ... + c_nv_n = v_i, which is the zero vector.
This implies that we have found a nontrivial linear combination of the vectors in B that equals the zero vector. Therefore, B is linearly dependent.
The reason behind this is that the presence of the zero vector in a set of vectors automatically guarantees linear dependence. Any set containing the zero vector can be linearly dependent because we can always choose the scalar coefficient of the zero vector to be non-zero, resulting in a nontrivial linear combination equaling the zero vector.

The number 112 when divides by the number 8 gives the result 14.
To find the result of 112 divided by 8 using the number line, we can follow these steps:
1. Start at 0 on the number line.
2. Move along the number line in increments of 8 until you reach the number 112.
0 - 8 - 16 - 24 - 32 - 40 - 48 - 56 - 64 - 72 - 80 - 88 - 96 - 104 - 112
3. Count the number of times you moved in increments of 8.
It takes 14 increments of 8 to reach 112.
4. Therefore, 112 divided by 8 is equal to 14.
So, the result of 112 divided by 8 is 14.

Draw your own triangle given the indicated measures and solve for the other parts using Sine Law. Write an explanation in each line of your solution. 1.
By applying the Sine Law and rearranging the equation, we can determine the missing parts of the triangle and solve for angles and sides.
We will draw a triangle based on the given measures and then use the Sine Law to solve for the other parts. The Sine Law relates the measures of angles and sides in a triangle.
Let's assume we have a triangle with sides a, b, and c, and angles A, B, and C, respectively. To solve for the other parts using the Sine Law, we need at least one side and its corresponding angle.
Suppose we are given side A and angle A. We can draw the triangle accordingly. The side opposite angle A will be labeled "a," and angle A will be opposite side a.
Next, we can use the Sine Law, which states that the ratio of a side length to the sine of its opposite angle is constant. The Sine Law can be expressed as:
a/sin(A) = b/sin(B) = c/sin(C)
With this information, we can solve for the other parts of the triangle. If we are given side A and angle A, we can use the Sine Law to find the ratios of the other sides to their corresponding angles.
By rearranging the Sine Law equation, we can solve for the unknown sides or angles. For example, to find side b, we have:
b = (a * sin(B)) / sin(A)
Similarly, we can find side c using:
c = (a * sin(C)) / sin(A)
And we can find the other angles using the inverse sine function:
B = sin^(-1)((b * sin(A)) / a)
C = sin^(-1)((c * sin(A)) / a)
By applying the Sine Law and rearranging the equation, we can determine the missing parts of the triangle and solve for angles and sides.

-4x^(2)-3x+14=4 select all statements that apply
Answer:
x = - 2, x = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
Given
- 4x² - 3x + 14 = 4 ( subtract 4 from both sides )
- 4x² - 3x + 10 = 0 ( multiply through by - 1 to clear the leading negative )
4x² + 3x - 10 = 0
Consider the product of the factors of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × - 10 = - 40 and sum = + 3
The factors are + 8 and - 5
Use these factors to split the x- term
4x² + 8x - 5x - 10 = 0 ( factor the first/second and third/fourth terms )
4x(x + 2) - 5(x + 2) = 0 ← factor out (x + 2) from each term
(x + 2)(4x - 5) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
4x - 5 = 0 ⇒ 4x = 5 ⇒ x = [tex]\frac{5}{4}[/tex]

How do I solve this?
Answer:
x=60° , y=30° , z= 75°
Step-by-step explanation:
note...an equilateral triangle has the same angles all equal to 60°. so based on this x is 60°
the angle next to y is on a straight line therefore
60 +y =90
y=90-60
y=30°
the triangle with the y and z angles is an isosceles triangle...so the base angles must be equal
z+z+30=180
2z+30=180
2z=180-30
2z=150
[tex] \frac{2z}{2} = \frac{150}{2} [/tex]
z=75°
