Answer: The distance between the girls is 362.8 meters.

Step-by-step explanation:

So we have two triangle rectangles that have a cathetus in common, with a length of 160 meters.

The adjacent angle to this cathetus is 40° for Anna, then the opposite cathetus (the distance between Anna and the tower) can be obtained with the relationship:

Tan(A) = opposite cath/adjacent cath.

Tan(40°) = X/160m

Tan(40°)*160m = 134.3 m

Now, we can do the same thing for Veronica, but in this case the angle adjacent to the tower is 55°

So we have:

Tan(55°) = X/160m

Tan(55°)*160m = X = 228.5 m

And we know that the girls are in opposite sides of the tower, so the distance between the girls is equal to the sum of the distance between each girl and the tower, then the distance between the girls is:

Dist = 228.5m + 134.3m = 362.8m

The band will march 3.2 kilometers at the same rate.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

800 meters for every 15 minutes

800 meters  ⇔ 15 minutes

Multiply 4 by both sides

3200 meters ⇔ 60 minutes

Now,

60 minutes = 1 hour

And,

Since 1000 meter = 1 kilometer ⇒ 3200 meter = 3.2 kilometer.

So,

1 hour ⇔ 3.2-kilometer.

Hence "The band will march 3.2 kilometers at the same rate".

The volume of the rectangular prism is 8 cubic meters when it takes 8 blocks with a side lengths of one fourths meter to fill a rectangular prism.

If it takes 8 blocks with a side length of one fourths meter to fill a rectangular prism, we can assume that the volume of each block is:

\((1/4)^3 = 1/64m^3\)

To find the volume of the rectangular prism, we need to know its dimensions. We can express its volume as one of the given options:

One eights cubic meters: This means the volume is 1/8 cubic meters. We can find the number of blocks needed to fill this volume by dividing the total volume by the volume of each block:

(1/8) ÷ (1/64) = 8 blocks

This doesn't match the given information, since we were told that it takes 8 blocks to fill the prism, not that the volume of the prism is 8 times the volume of a block.

One fourths cubic meters: This means the volume is 1/4 cubic meters. We can find the number of blocks needed to fill this volume in the same way:

(1/4) ÷ (1/64) = 16 blocks

This also doesn't match the given information.

Half cubic meters: This means the volume is 1/2 cubic meters. We can find the number of blocks needed to fill this volume:

(1/2) ÷ (1/64) = 32 blocks

Since it takes 8 blocks to fill the prism, this option doesn't match either.

One cubic meter: This means the volume is 1 cubic meter. We can find the number of blocks needed to fill this volume:

1 ÷ (1/64) = 64 blocks

This matches the given information, since it takes 8 blocks to fill the prism, which means there are 8 layers of 8 blocks each. Therefore, the dimensions of the prism are:

length = 8 × (1/4) = 2 meters

width = 8 × (1/4) = 2 meters

height = 8 × (1/4) = 2 meters

So the volume of the rectangular prism is:

volume = length × width × height = 2 × 2 × 2 = 8 cubic meters.

The value of \( r \) is approximately 12.56 feet.

To find the value of \( r \), we can use the formula for the area of a sector of a circle. The formula is given by:

\[ \text{Area of sector} = \frac{\text{angle}}{2\pi} \times \pi r^2 \]

In this case, the angle is given as \( 3.8 \) radians, and the area of the sector is given as \( 47.5 \) square feet. We can substitute these values into the formula and solve for \( r \).

\[ 47.5 = \frac{3.8}{2\pi} \times \pi r^2 \]

First, we simplify the equation by canceling out the common factors of \( \pi \).

\[ 47.5 = \frac{3.8}{2} \times r^2 \]

Next, we can multiply both sides of the equation by \( \frac{2}{3.8} \) to isolate \( r^2 \).

\[ r^2 = \frac{47.5 \times 2}{3.8} \]

Simplifying further:

\[ r^2 = \frac{95}{3.8} \]

Finally, we can take the square root of both sides to solve for \( r \).

\[ r = \sqrt{\frac{95}{3.8}} \]

Using a calculator, we find that \( r \) is approximately 6.28 feet.

Therefore, the value of \( r \) is approximately 12.56 feet.

Andy has 15 coins made up of quarters and half dollars, and their total value is $5.00.

He has 10 quarters and 5 half dollars.

To find this answer, we can set up the following equation: 0.25Q + 0.50H = 5.00, where Q represents the number of quarters and H represents the number of half dollars. Solving for Q, we get Q = 10. Therefore, Andy has 10 quarters and 5 half dollars.

To solve this equation, we can use algebra to isolate the variable Q. We can start by subtracting 0.50H from both sides, giving us 0.25Q = 5.00 - 0.50H.

Next, we can divide both sides by 0.25, giving us Q = (5.00 - 0.50H) / 0.25. Therefore, we can substitute the values for 5.00 and 0.50H and solve for Q, giving us Q = 10.

Answer:

Step-by-step explanation:

substitute the value of y in the first equation.

7x-3(5x-4)=20

7x-15x+12=20

-8x=20-12

x=8/-8

x= -1

then you substitute the value of x on the y equation to find y

y=5×-1 -4

y= -5-4

y= -9

Answer:

x = -1, and y = -9

Step-by-step explanation:

This is done by solving one of the two equations for x or y, then substituting it in place of that variable in the other equation.

Since y is already clearly defined in the second equation let's go with that:

\(Given\ 7x - 3y = 20,\ and\ y = 5x - 4\)

\(7x - 3(5x - 4) = 20\)

\(7x - 15x + 12 = 20\)

\(7x - 15x = 20 - 12\)

\(-8x = 8\)

\(x = -1\)

Now we can replace x in the equation for y with -1:

\(y = 5(-1) - 4\)

\(y = -5 - 4\)

\(y = -9\)

To make sure our answers are correct, let's substitute them into the original equations:

\((-9) = 5(-1) - 4\\-9 = -5 - 4\\-9 = -9\)

Good, let's test the other equation

\(7(-1) - 3(-9) = 20\\-7 - (-27) = 20\\-7 + 27 = 20\\20 = 20\)

So we know that our answer is correct.

You failed to make the minimum payment by the due date. This is an action that can result in a message that "you've triggered the Penalty APR so that it has now climbed to 28.99%."

A charge APR is a charge that can be applied if you don't pay your bills on time. It may be set up so that future transactions may be subject to a penalty APR that is higher than the card's standard rate.

If the minimum payment was not made by the due date, Penalty APR would be applied.

But if the card also has a penalty APR and you trigger it, you will likely lose that promotional offer. Federal consumer protections that limit penalty APRs don't apply to small-business credit cards. That means issuers can be more punitive, such as applying penalty APRs sooner than 60 days after not making payments.

A) the area of a rectangle with side lengths of 6 and 4 units is:Area = length × widthArea = 6 units × 4 unitsArea = 24 square units. B) we can use rectangular areas to help us solve mathematical problems.

a) Let's consider a rectangle with side lengths of 6 and 4 units. We can find the area of the rectangle by tiling it. To do this, we can divide the rectangle into unit squares, which means 24 squares altogether.

This shows that the area of the rectangle is 24 square units.We can also use multiplication to find the area of the rectangle. The area of a rectangle is found by multiplying the length by the width.

Therefore, the area of a rectangle with side lengths of 6 and 4 units is:Area = length × widthArea = 6 units × 4 unitsArea = 24 square units

Therefore, we see that both the tiling method and the multiplication method give the same answer.

b) When solving real-world and mathematical problems that involve rectangles, we often need to find their areas. To do this, we can multiply the length and width of the rectangle.

For example, consider a rectangle with a length of 7 feet and a width of 5 feet. To find the area of this rectangle, we can multiply 7 by 5. Therefore, the area of the rectangle is:Area = length × widthArea = 7 feet × 5 feetArea = 35 square feetWe can also represent whole-number products as rectangular areas in mathematical reasoning.

For example, if we know that the area of a rectangle is 20 square units and one side length is 4 units, we can use this information to find the other side length. We can reason that if the area is 20 square units and one side length is 4 units, the other side length must be 5 units, since 4 × 5 = 20.

The three consecutive integers are 10, 11, and 12.

To find three consecutive integers, the sum of whose squares is 65 more than three times the square of the smallest, follow these steps:

1. Let the smallest integer be x. Then, the other two consecutive integers are x + 1 and x + 2.

2. The sum of their squares is x^2 + (x + 1)^2 + (x + 2)^2.

3. The given condition is that this sum is 65 more than three times the square of the smallest integer: x^2 + (x + 1)^2 + (x + 2)^2 = 3x^2 + 65.

4. Simplify the equation:
  x^2 + (x^2 + 2x + 1) + (x^2 + 4x + 4) = 3x^2 + 65

5. Combine like terms:
  3x^2 + 6x + 5 = 3x^2 + 65

6. Subtract 3x^2 from both sides to eliminate the x^2 terms:
  6x + 5 = 65

7. Subtract 5 from both sides:
  6x = 60

8. Divide by 6:
  x = 10
