The question: What theorem would you use to write proportion for this figure?

It's the same question for each problem.

Answer:

Step-by-step explanation:

Since PQR is a triangle with QR = PQ, we have:

∠PQR = ∠QPR (since the angles opposite to equal sides are equal)

Let x be the measure of ∠QPR. Then:

∠PQR + ∠QPR + ∠R = 180° (sum of angles in a triangle)

x + x + 50° = 180°

2x = 130°

x = 65°

Therefore, the measure of ∠QPR is 65°.

i tootk the test

Step-by-step explanation:

To solve the system of equations:

3x - 4y = 16

2x + 3y = 5

We can use either substitution or elimination method. Here, we will use the elimination method:

Multiply the second equation by 4 to get:

8x + 12y = 20

Now we can add this equation to the first equation:

3x - 4y + 8x + 12y = 16 + 20

Simplifying the left side and adding the right side, we get:

11x = 36

Dividing both sides by 11, we get:

x = 36/11

Substituting this value of x into the second equation, we get:

2(36/11) + 3y = 5

Multiplying through by 11 to eliminate the fraction, we get:

72/11 + 3y = 55/11

Subtracting 72/11 from both sides, we get:

3y = -17/11

Dividing both sides by 3, we get:

y = -17/33

Therefore, the solution to the system of equations is:

x = 36/11, y = -17/33

or in decimal form,

x ≈ 3.27, y ≈ -0.52

The statement that could be true for g is D. g(-13) = 20.

We are given that the function g has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45, and we also know that g(0) = -2 and g(-9) = 6.

We can use this information to eliminate the statements that are not true and find the one that could be true for g.

Therefore, g(-13) is greater than g(-9) and could be 20, so this statement could be true.

Answer:

(-7,2)

Step-by-step explanation:

Answer:

Step-by-step explanation:

We know that the area of the plane shape is given by A = (10x - 2) cm^2, and we also know that:

A is not greater than or equal to 12 cm^2 (i.e., A < 12), and

A is not less than 2 cm^2 (i.e., A > 2).

To find the smallest possible area of the shape, we need to find the smallest possible value of x that satisfies these conditions.

From the given conditions, we have:

10x - 2 < 12

10x < 14

x < 1.4

and

10x - 2 > 2

10x > 4

x > 0.4

Therefore, the smallest possible value of x that satisfies both conditions is:

0.4 < x < 1.4

To find the smallest possible area, we can substitute the lower bound of x into the area formula:

A = (10x - 2) cm^2

A = (10 × 0.4 - 2) cm^2

A = 2 cm^2

Therefore, the smallest possible area of the shape is 2 cm^2.

Taking the quantities by volume of each potion into consideration, we can respectively answer 250ml (A), 40 mL of red and 60 mL of blue potion (B), and no (C).

For question A: Let x be the amount of red potion (in mL) that must be added to 500 mL of blue potion to produce a potion that is 40% magical syrup by volume. The amount of magical syrup in the red potion is 0.6x, and the amount of magical syrup in the blue potion is 0.3(500) = 150. The total amount of syrup in the final mixture is 0.4(500 + x), and the amount of magical syrup in the final mixture is 0.4x + 150. We can set up the equation:

0.4x + 150 = 0.4(500 + x)

Solving for x, we get x = 250 mL. Therefore, 250 mL of red potion must be added to 500 mL of blue potion to produce a potion that is 40% magical syrup by volume.

For question B: Let x be the amount of red potion (in mL) and y be the amount of blue potion (in mL) that must be combined to produce 100 mL of a potion that is 54% magical syrup by volume. The amount of magical syrup in the red potion is 0.6x, and the amount of magical syrup in the blue potion is 0.3y. The total amount of syrup in the final mixture is x + y, and the amount of magical syrup in the final mixture is 0.6x + 0.3y. We can set up the equations:

x + y = 100 (equation 1)

0.6x + 0.3y = 0.54(100) (equation 2)

Solving for x and y, we get x = 40 mL and y = 60 mL. Therefore, 40 mL of red potion and 60 mL of blue potion must be combined to produce 100 mL of a potion that is 54% magical syrup by volume.

For question C: No, there does not exist a combination of red potion and blue potion that can produce a potion that is 75% magical syrup by volume. The amount of magical syrup in the red potion is 60%, which is more than twice the amount of magical syrup in the blue potion (30%). Therefore, any combination of the two potions will always have less than 60% magical syrup by volume.

The length of the bar is doubled because it was stretched to twice the length of the original bar.

A multiplication equation that shows how the length is scaled is 2 × 8 = 16.

The length of the bar is halved because it was compressed to one-half the length of the original bar.

A multiplication equation that shows how the length is scaled is 1/2 × 8 = 4.

In Mathematics and Geometry, the scale factor of a geometric figure can be calculated by dividing the length of the image (new figure) by the length of the pre-image (original figure):

Since the original bar has a length of 8 units, we can logically deduce that its length became doubled because it was expanded to twice the length of the original bar. Therefore, a multiplication equation to model this expansion is given by:

2 × 8 = 16.

Conversely, the original bar has a length of 4 units, we can logically deduce that its length was halved because it was shrunk to one-half the length of the original bar. Therefore, a multiplication equation to model this compression is given by:

The solution of the quadratic equation x² + 10x -4 found using the quadratic formula is: x = -5 ± √29.

Sometimes, factoring the quadratic, setting its factor equal to zero, but then solving each factor is the quickest way to find the answer to "ax² + bx + c = 0" given the value of x.

Yet, there are situations when the quadratic is too complicated, it just doesn't factor in anyway, or you might not feel like factoring at all. The Quadratic Formula also can provide the solutions for you even when factoring sometimes isn't going to be successful.

The given equation:

x² + 10x -4

The general quadratic equation can be written as:

ax² + bx +c

Then, roots of the equation can be found using quadratic formula:

x = -b±√(b²-4ac))/(2a)

a = 1, b = 10 and c = -4

Put the values:

x = [ -10 ± √(10²- 4*1*(-4))]/ (2*1)

x = [ -10 ± √(100 + 16)]/ 2

x = [-10 ± √116] / 2

x =  [-10 ± 2√29] / 2

x = -5 ± √29

She received 5 or more emails in the same time period with a probability of 0.05265.

Simply put, probability is the likelihood that something will occur.

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

The higher the likelihood, the more likely it is that the event will take place.

So, the probability would be:

We know that λ = 2.

The formula for the poisson distribution states:

P(x = x) = (λˣ * e^⁻ˣ) / x!

P(x = 1) = (2¹ *e⁻²) / 1!

P(x = 1) = (2 * 0.1353352) = 0.2706

Then,

P(x ≥ 5) = 1 - P(x < 5)

1 - P(x < 5) = 1 - [p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)]

We gather the individual probabilities and combine them. We can use a Poisson distribution calculator to speed up computations:

1 - P(x < 5) = 1 - (0.13534+0.27067+0.27067+0.18045+0.09022)

1 - P(x < 5) = 1 - 0.94735 = 0.05265

P(x ≥ 5) = 1 - P(x < 5) = 0.05265

Willka would need 6 liters of paint to cover an area of 27 square meters according to the ratio.

A ratio is a comparison of two or more values or quantities. It is a way of expressing the relationship between two or more quantities in a mathematical form. A ratio is typically expressed in the form of "a:b" or "a to b", where a and b are two values being compared.

According to question:

To find the coverage per liter of paint, we can divide the total area covered by the amount of paint used.

In this case, we can divide 13.5 m² by 3 L:

Coverage per liter = 13.5 m² / 3 L = 4.5 m²/L

This means that with 1 liter of paint, Willka can cover an area of 4.5 square meters.

If we know the area to be painted, we can use this ratio to determine how much paint is needed.

For example, if we want to paint an area of 27 square meters, we can calculate:

Paint needed = area to be painted / coverage per liter = 27 m² / 4.5 m²/L = 6 L

So Willka would need 6 liters of paint to cover an area of 27 square meters.

Answer: 2.5 hours

Step-by-step explanation:

Let's call the number of signatures that Steve needs to collect "x". We know that Dirk has 20 signatures, so he needs to collect "x - 20" more signatures to have the same number as Steve.

We can set up an equation to represent this:

6h + 20 = 10h + x - 20

Simplifying this equation, we get:

x = 4h + 40

So, Steve needs to collect 4 signatures more per hour than Dirk to eventually collect the same number of signatures. We can solve for "h", the number of hours it will take for them to have the same number of signatures:

6h + 20 = 10h + (4h + 40)

6h + 20 = 14h + 40

8h = 20

h = 2.5

So, it will take 2.5 hours for Dirk and Steve to have collected the same number of signatures.
