Mariam will have purchased 3.5 pounds of fruit if she purchases 3 pounds of apples and 0.5 pounds of strawberries.

Mariam will purchase a total of (x + y) pounds of fruit if she purchases x pounds of strawberries and y pounds of apples.

The arithmetic operations were used to arrive at the answer.

The four basic operations—often referred to as "arithmetic operations"—are thought to be able to describe all real numbers. Divide, multiply, add, and subtract are the four mathematical operations that result in the quotient, product, sum, and difference.

We are given that Mariam buys 0.5 pounds of strawberries and 3 pounds of apples.

So, the total pounds of fruit bought = 0.5 + 3 = 3.5

Similarly, if she buys x pounds of strawberries and y pounds of apples, then the total amount of pound of fruits  = (x + y)

Hence, the required solution has been obtained.

Answer: J. A = 12 (4⋅6).

Step-by-step explanation:

Answer: J. A = 12 (4⋅6).

This equation can be used to find the area of the triangle in the diagram because it uses the formula for the area of a triangle, which is A = 1/2 * b * h, where b is the base and h is the height. Since the triangle in the diagram has a base of 4 and a height of 6, the equation A = 12 (4⋅6) can be used to find the area.

Answer:

The diagram is not provided, so it's difficult to determine the exact dimensions of the triangle and parallelogram. However, we can make some general observations to determine which equation can be used to find the area of the triangle.

First, we know that the area of a triangle is given by the formula:

A = 1/2 * base * height

We also know that the area of a parallelogram is given by the formula:

A = base * height

In the diagram, the triangle can be formed into a parallelogram by taking one of its sides and using it as the base of the parallelogram. The height of the parallelogram is the same as the height of the triangle.

Based on these observations, we can conclude that the equation that can be used to find the area of the triangle is:

A = 1/2 * base * height

where the base is one of the sides of the triangle, and the height is the height of the parallelogram (which is the same as the height of the triangle).

None of the answer choices provided match this equation, so the correct answer is not given.

Answer:

Point D is the solution to the system of equations.

Step-by-step explanation:

When asked for a solution involving 2 equations, the goal is to find a point (x,y) that would be a solution to both equations.  Any point on a line that is defined by an equation is a solution to that equation.  For an equation of y = 2x + 2, possible solutions are (1,4), (2,6), (5,12) etc.  These points all lie on the line formed by that equation.  There are an infinite number of possible solutions.  If a second eqaution is added, there is now a constraint on the possible answers.  The goal is to find a point that satisfies both equations.

If a seond equation of y = 1x + 3 were matced with y=2x+2, both are straight lines, but with different slopes.  So they will intersect at some point.  One may either solve mathematically using substitution, or by graphing, as was done here.  

Matematically:

y = 2x + 2

y = 1x + 3

Rearrange either equation to isolate a variable, x or y.  These are already isolated (since I made them up) so go to the next step of substituting one expression of y into the other:

y = 1x + 3

2x + 2 = 1x + 3

x = 1

Now use this value of x to find y:

y = 2x + 2

y = 2*(1) + 2

y = 4

The point these two lines intersect is (1,4) and is the "solution" to this series of equations.

The man has 7 shirts in total, so he can take 3 of those shirts on his 3-day trip without repetition. This means that he can make 7 different combinations of shirts, since each shirt has only one choice. For example, he could take shirts A, B, and C; or he could take shirts D, E, and F; or he could take shirts G, A, and B. In total, he has 7 different combinations of shirts to choose from.
The number of combinations of shirts that the man can take without repetition can be found using the formula for combinations, which is:
C(n, r) = n! / (r! * (n-r)!)

In this case, n = 7 (the total number of shirts) and r = 3 (the number of shirts he will take with him).

Plugging in these values into the formula, we get:

C(7, 3) = 7! / (3! * (7-3)!)

C(7, 3) = 7! / (3! * 4!)

C(7, 3) = 5040 / (6 * 24)

C(7, 3) = 5040 / 144

C(7, 3) = 35

The equation is true, the point (-1,6) does indeed lie on the line (-3,5).

The equation of a line is typically written in the form y = mx + b, where m is the slope and b is the y-intercept. In order to determine whether or not the point (-1,6) lies on the line (-3,5), we need to plug in the x and y values of the point into the equation of the line and see if the equation is true.

First, we need to find the slope of the line. The slope is the difference in the y values divided by the difference in the x values:

m = (5 - 6)/(-3 - (-1)) = -1/-2 = 1/2

Next, we need to find the y-intercept of the line. We can do this by plugging in one of the points and solving for b:

5 = (1/2)(-3) + b

b = 5 + (3/2) = 13/2

Now we have the equation of the line: y = (1/2)x + 13/2

Finally, we can plug in the x and y values of the point (-1,6) to see if the equation is true:

6 = (1/2)(-1) + 13/2

6 = -1/2 + 13/2

6 = 12/2

6 = 6

The solutions to the given trigonometric equation on the interval [0,2π) are θ = 2π/3 and θ = 4π/3. These values can also be expressed in decimal form as θ = 2.09 and θ = 4.19, rounded to two decimal places

To solve the given trigonometric equation on the interval [0,2π), we need to use the quadratic formula.

First, let us rewrite the equation in terms of x:
2x^2 + 5x + 2 = 0

Next, we can apply the quadratic formula:
x = (-b ± √(b^2 - 4ac))/(2a)

Plugging in the values from the equation:
x = (-(5) ± √((5)^2 - 4(2)(2)))/(2(2))

Simplifying:
x = (-5 ± √(25 - 16))/4
x = (-5 ± √9)/4
x = (-5 ± 3)/4

This gives us two possible values for x:
x = (-5 + 3)/4 = -2/4 = -0.5
x = (-5 - 3)/4 = -8/4 = -2

Now we need to convert these values back to θ by using the inverse cosine function:
θ = cos^-1(-0.5)
θ = cos^-1(-2)

The first value, θ = cos^-1(-0.5), gives us two solutions on the interval [0,2π):
θ = 2π/3 and θ = 4π/3

The second value, θ = cos^-1(-2), does not give us any solutions on the interval [0,2π) because the cosine function only takes on values between -1 and 1.

Therefore, the solutions to the given trigonometric equation on the interval [0,2π) are θ = 2π/3 and θ = 4π/3. These values can also be expressed in decimal form as θ = 2.09 and θ = 4.19, rounded to two decimal places.

The equation of the circle centered at (-4,3) with radius 3 is (x + 4)^2 + (y - 3)^2 = 9. Simplifying this equation means to simplify the terms in the equation by using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.

In this equation, the hypotenuse is the radius, which is 3, and the sides are (x + 4) and (y - 3). Substituting the values into the Pythagorean Theorem, we get (x + 4)^2 + (y-3)^2 = 9, which is the equation of the circle centered at (-4,3) with radius 3. This equation can be simplified further by factoring the terms, which yields (x + 4) (x + 4) + (y - 3) (y - 3) = 9. This is the fully simplified equation of the circle.

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n. To demonstrate the equations using induction, we need to follow three steps: the base case, the induction hypothesis, and the induction step.

1) P(n) : 2 + 4 + 6 + ⋯+ 2n= n(n+ 1), ∀ n∈ℕ.

Base case: For n = 1, the equation becomes 2 = 1(1+1), which is true.

Induction hypothesis: Assume the equation is true for n = k, that is, 2 + 4 + 6 + ⋯+ 2k= k(k+ 1).

Induction step: We need to show that the equation is also true for n = k+1. That is, 2 + 4 + 6 + ⋯+ 2k + 2(k+1)= (k+1)(k+2).

Using the induction hypothesis, we can substitute k(k+1) for 2 + 4 + 6 + ⋯+ 2k:

k(k+1) + 2(k+1) = (k+1)(k+2)

Distributing the (k+1) on the right side of the equation gives us:

k(k+1) + 2(k+1) = k(k+1) + 2(k+1)

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n.

2) ∑i^2= n(n+1)(2n+1)/6, ∀ n∈ℕ.

Base case: For n = 1, the equation becomes 1^2 = 1(1+1)(2(1)+1)/6, which simplifies to 1 = 1, which is true.

Induction hypothesis: Assume the equation is true for n = k, that is, ∑i^2= k(k+1)(2k+1)/6.

Induction step: We need to show that the equation is also true for n = k+1. That is, ∑i^2 + (k+1)^2 = (k+1)(k+2)(2(k+1)+1)/6.

Using the induction hypothesis, we can substitute k(k+1)(2k+1)/6 for ∑i^2:

k(k+1)(2k+1)/6 + (k+1)^2 = (k+1)(k+2)(2(k+1)+1)/6

Multiplying both sides of the equation by 6 gives us:

k(k+1)(2k+1) + 6(k+1)^2 = (k+1)(k+2)(2(k+1)+1)

Distributing the (k+1) on both sides of the equation gives us:

k(k+1)(2k+1) + 6(k+1)^2 = k(k+1)(k+2)(2k+3)

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n.

We can use equation (1) to solve for d in terms of q:

d = 21 - q

Substituting this expression for d into equation (2), we get:

10(21 - q) + 25q = 435

210 - 10q + 25q = 435

15q = 225

q = 15

So, Quinn has 15 quarters. Substituting this value into equation (1), we get:
