The best inequality that represents the relationship between the amount of hydrochloric acid (x) and the amount of distilled water (y) in the given graph is 3y - 2x > 0, option D is correct.

The graph shows a straight line with a negative slope passing through the origin. As the amount of hydrochloric acid, x, increases, the amount of distilled water, y, decreases

To see why, let's use a point on the line, such as (2, 3), and plug it into the inequality. We get:

3(3) - 2(2) > 0

9 - 4 > 0

This is true, so the point (2, 3) is a solution to the inequality. Any point on the line will also satisfy this inequality since it represents all possible combinations of x and y that Corrine can use in her experiment.

Alternatively, we can rewrite the inequality in slope-intercept form:

y < (2/3)x

This means that the y-values on the line are less than the corresponding values of (2/3)x. So as x increases, y must decrease to stay below the line. This confirms that 3y - 2x > 0 is the correct inequality.

Hence, option D is correct.

The area of a rectangle can be found by multiplying its length and width.

To find the area of rectangles with different perimeters, we need to use the formula:

Area = length x width

Possible dimensions:

Length = 5 cm, Width = 3 cm

Length = 4 cm, Width = 4 cm

Area of the first rectangle = 5 cm x 3 cm = 15 cm²

Area of the second rectangle = 4 cm x 4 cm = 16 cm²

Possible dimensions:

Length = 6 cm, Width = 4 cm

Length = 5 cm, Width = 5 cm

Area of the first rectangle = 6 cm x 4 cm = 24 cm²

Area of the second rectangle = 5 cm x 5 cm = 25 cm²

Possible dimensions:

Length = 4 cm, Width = 3 cm

Area of the rectangle = 4 cm x 3 cm = 12 cm²

Since LMNO is a parallelogram, we know that opposite sides are equal in length. Therefore, we can set NM and OL equal to each other:

NM = OL

We also know that NM = x + 27 and OL = 3x + 9, so we can substitute these expressions into the equation:

x + 27 = 3x + 9

Solving for x:

2x = 18

x = 9

Now that we know x, we can substitute it back into the expressions for NM and OL:

that is, Volume = base area x height

the base area is the hexagon, and the height is given as 12.

Think of dividing the hexagon into 6 equal triangles, with height 7.8

so the area of all 6 triangles, (effectively the area of the hexagon), will be:

6(0.5 x 9 x 7.8) = 210.6 in^2

multiply this by the height to get the volume:

210.6 x 12 = 2527.2 in^3

The number of times that the little monsters will do an overhead press and a squat at the same instant  during the drill is: 3 times

We are told that, Rote tells the little monsters to carry out an overhead press every 12 seconds and then also a squat every 30 seconds.

Thus, prime factorization of 12: 2² x 3.

Thus, prime factorization of 30: 2 x 3 x 5.

For us to get the least common multiple, we will have to find the highest power of each of the prime factors that show up in either factorization. Therefore, we can say that the smallest common multiple of 12 and 30 are: 2² x 3 x 5 = 60

This tells us that the little monsters will carry out an overhead press and then a squat at the same instant for every 60 seconds.

For us to find how many times this will occur during the 200-second drill, we will then divide 200 by 60:

200 ÷ 60 = 3 remainder 20

This tells us that there will exist 3 complete cycles of both of the exercises during the 200-second drill, with an additional 20 seconds left over.

Therefore, we can say that the little monsters will do an overhead press and a squat at the same instant 3 times during the drill.

The cost of one apple is $2.15.

To find the cost of one apple, we can set up a system of equations with the given information. Let's use A for the cost of one apple and B for the cost of one banana:

1) 4A + 9B = $12.70
2) 8A + B = $17.70

Now, we can solve this system of equations. We can multiply equation 1 by 2 to match the number of apples in equation 2:

1) 8A + 18B = $25.40

Now subtract equation 2 from the modified equation 1:

(8A + 18B) - (8A + B) = $25.40 - $17.70
17B = $7.70

Now, divide by 17 to find the cost of one banana:
B = $7.70 / 17 = $0.45

Now that we know the cost of one banana, we can substitute B in equation 2 to find the cost of one apple:

8A + ($0.45) = $17.70
8A = $17.25
A = $17.25 / 8 = $2.15

Using Pythagorean theorem the distance between the school and the fire station is approximately 4.7 miles, while the distance between the school and the hospital is approximately 7.8 miles.

To solve this problem, we can use the Pythagorean theorem to find the distances and then add them up to get the total distance between the school and the fire station, and then between the school and the hospital.

Part A:

Let's call the middle school point A, Town Hall point B, and the fire station point C. We can draw a right triangle with AB as the base, BC as the height, and AC as the hypotenuse. Using the Pythagorean theorem, we have:

AC^2 = AB^2 + BC^2

AC^2 = 4.3^2 + 1.7^2

AC^2 = 18.98 + 2.89

AC^2 = 21.87

AC ≈ 4.7 miles (rounded to the nearest tenth)

Therefore, the length of the straight line between the school and the fire station is approximately 4.7 miles.

Part B:

Let's call the hospital point D. We can draw another right triangle with CD as the base, BC as the height, and BD as the hypotenuse. Using the Pythagorean theorem, we have:

BD^2 = BC^2 + CD^2

BD^2 = 1.7^2 + 3.1^2

BD^2 = 2.89 + 9.61

BD^2 = 12.5

BD ≈ 3.5 miles (rounded to the nearest tenth)

Now, we can add the distance between A and B (4.3 miles) to the distance between B and D (3.5 miles) to get the total distance between A and D:

AD ≈ 7.8 miles (rounded to the nearest tenth)

Therefore, the length of the straight line between the school and the hospital is approximately 7.8 miles.

To find the temperature at 6pm, we need to start with the temperature at 9am and then add or subtract the changes in temperature that occurred during the day.

We know that the temperature at 9am was -1.9°F. Between 9am and noon, the temperature rose 11.3°F, so at noon the temperature was:

-1.9 + 11.3 = 9.4°F

Between noon and 3pm, the temperature dropped 7.9°F, so at 3pm the temperature was:

9.4 - 7.9 = 1.5°F

Between 3pm and 6pm, the temperature dropped 12.7°F, so at 6pm the temperature was:

Answer:

Step-by-step explanation:

Let's call the two numbers x and y. We know that:

x + y = 30 (since the sum of the two numbers is 30)

We want to find the values of x and y that maximize their product, which is given by:

P = xy

To solve for x and y, we can use the fact that the sum of the two numbers is 30, so we can rewrite one of the numbers in terms of the other:

y = 30 - x

Substituting this into the equation for the product, we get:

P = x(30 - x)

Expanding this expression, we get:

P = 30x - x^2

To find the maximum value of P, we can take the derivative of this expression with respect to x and set it equal to zero:

dP/dx = 30 - 2x = 0

Solving for x, we get:

x = 15

So one of the numbers is x = 15, and the other is y = 30 - x = 15.

To confirm that this gives the maximum product, we can take the second derivative of P with respect to x:

d2P/dx2 = -2

Since the second derivative is negative, this means that the function P = 30x - x^2 has a maximum at x = 15.

Therefore, the two numbers are 15 and 15, and their product is maximized at P = 15 * 15 = 225.
