Step-by-step explanation:

The fraction 9/80 cannot be simplified further, so that is the final answer.

Claudia has a total of 16/3 gallons of paint, and 3/5 gallons of that amount is red. To determine the fraction of Claudia's paint that is red, we need to express the amount of red paint as a fraction of the total amount of paint.

Let's denote the fraction of red paint as r and the total amount of paint as p.

We know that the amount of red paint is 3/5 gallons, which can be expressed as r = 3/5.

The total amount of paint is 16/3 gallons, which can be expressed as p = 16/3.

To find the fraction of Claudia's paint that is red, we divide the amount of red paint by the total amount of paint:

Fraction of red paint = r/p = (3/5) / (16/3).

To divide fractions, we multiply the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction:

Fraction of red paint = (3/5) * (3/16) = 9/80.

Therefore, the fraction of Claudia's paint that is red is 9/80.

It's important to note that fractions should be simplified if possible. In this case, the fraction 9/80 cannot be simplified further, so that is the final answer.

In conclusion, the fraction of Claudia's paint that is red is 9/80.

Answer:

64.25

Step-by-step explanation:

Subtract 145.25 from 209.5, resulting in 64.25.

Answer:

To solve the equation 4a + 3 = 5a - 4, we want to isolate the variable "a" on one side of the equation.

First, we can simplify both sides of the equation by combining like terms:

4a + 3 = 5a - 4

Subtract 4a from both sides:

4a - 4a + 3 = 5a - 4a - 4

Simplify:

3 = a - 4

Next, we can add 4 to both sides of the equation to isolate "a" on one side:

3 + 4 = a - 4 + 4

Simplify:

7 = a

Therefore, the solution is a = 7

The correct answer that best describes randomization, a principle of experimental design is D. A feature of an experiment designed to isolate the variable under observation

It aims to create a comparison group or condition that does not receive the intervention being studied, allowing researchers to assess the specific effect of the intervention.

By controlling for other variables, researchers can attribute any observed differences between groups to the intervention rather than external factors.

Control is achieved by creating a control group that closely resembles the experimental group in all aspects except for the variable being studied, minimizing the influence of confounding variables and increasing the internal validity of the experiment.

Step-by-step explanation:

The distance traveled by the passenger train and the cattle train is equal to the total distance between them, which is 960 miles. Let x be the time (in hours) traveled by the passenger train and cattle train. Then, the equation that represents this situation is:

55x + 65x = 960

Simplifying the left-hand side of the equation, we get:

120x = 960

Dividing both sides by 120, we get:

x = 8

Therefore, the correct equation is:

B - 65x - 55x = 960

Step-by-step explanation:

In pic

(Hope this helps can I pls have brainlist (crown)☺️)

The solution to the equation 2/3 - 4x + 7/2 = -9x * 5/6 is x = 25/21.

To solve the equation: 2/3 - 4x + 7/2 = -9x * 5/6

Let's first combine like terms on the left side:

2/3 + 7/2 - 4x = -9x * 5/6

To add the fractions, we need a common denominator:

The common denominator for 3 and 2 is 6. So, we rewrite 2/3 as 4/6:

4/6 + 7/2 - 4x = -9x * 5/6

Now, we can add the fractions:

(4/6) + (7/2) = (8/12) + (42/12) = 50/12 = 25/6

The equation becomes:

25/6 - 4x = -9x * 5/6

Now, let's simplify further:

25/6 - 4x = -45x/6

To eliminate the fractions, we can multiply both sides by 6:

6 * (25/6 - 4x) = 6 * (-45x/6)

This simplifies to:

25 - 24x = -45x

Next, let's gather the x terms on one side of the equation:

-24x + 45x = 25

Combining the x terms:

21x = 25

Finally, solve for x by dividing both sides by 21:

x = 25/21

Therefore, the solution to the equation is x = 25/21.

Alice is 55 km from her starting point after walking a distance of 55 km along the perimeter of the park.

To find the distance Alice is from her starting point after walking along the perimeter of the park, we can use the concept of congruent sides in a regular hexagon.

The perimeter of a regular hexagon is equal to the sum of its six congruent sides. Given that each side of the hexagon is 22 km long, the total perimeter of the hexagon is 6 * 22 km = 132 km.

Since Alice walks a distance of 55 km along the perimeter of the park, we can determine the number of complete laps she makes around the hexagon by dividing the distance she walked by the perimeter of the hexagon: 55 km / 132 km = 0.4167 laps.

As Alice starts and ends at a corner of the hexagon, each complete lap brings her back to the same corner. Therefore, the fractional part of the number of laps represents the portion of the hexagon's perimeter she has traveled beyond the starting corner.

To find the remaining distance from Alice's current position to the starting point, we calculate the fractional part of the number of laps and multiply it by the perimeter of the hexagon: 0.4167 * 132 km = 55 km.

A regular hexagon is a polygon with six congruent sides. In this problem, the regular hexagon represents the shape of the park, and each side of the hexagon has a length of 22 km. The perimeter of the hexagon is found by multiplying the length of one side by the number of sides, which is 6. Therefore, the perimeter of the hexagon is 6 * 22 km = 132 km.

When Alice walks along the perimeter of the park for a distance of 55 km, we need to determine how many complete laps she makes around the hexagon. By dividing the distance she walked by the perimeter of the hexagon, we find that she completes approximately 0.4167 laps.

Since Alice starts and ends at a corner of the hexagon, each complete lap brings her back to the same corner. Therefore, the fractional part of the number of laps represents the portion of the hexagon's perimeter she has traveled beyond the starting corner.

In this case, multiplying 0.4167 by 132 km gives us a result of approximately 55 km. Therefore, Alice is 55 km from her starting point after walking a distance of 55 km along the perimeter of the park.

To find the surface area of the figure, we need to consider the individual surfaces and add them together.

First, let's identify the surfaces of the figure:

The lateral surface area of the larger prism (excluding the base)

The two bases of the larger prism

The lateral surface area of the smaller prism (excluding the base)

The two bases of the smaller prism

The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.

The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.

To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.

Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.
