it should be 412.38 but thats what i got on my math

Answer: [tex]412.38\text{ euros}[/tex].

Step-by-step explanation:

We are given that the worth of one dollar in euros = [tex]0.79\text{ euro}[/tex]

If we exchange $522 for euros, then to calculate the amount in euros we multiply the value of one dollar to 522 we get

[tex]522\times0.79=412.38\text{ euro}[/tex]

Therefore If you exchange $522 for euros, then we will get [tex]412.38\text{ euros}[/tex].

It will take 30 minutes for the pump to transfer 84 gallons of water out of the swimming pool using the flow rate of 2.8 gallons per minute.

To calculate the time it takes for the water pump to transfer 84 gallons of water at a rate of 2.8 gallons per minute, you can use the formula for time, which is time = total volume/flow rate.

Firstly, find the total volume of water to be transferred, which is 84 gallons.

Next, find the flow rate of the pump, which is 2.8 gallons per minute.

Divide the total volume by the flow rate to find the time: 84 gallons / 2.8 gallons per minute = 30 minutes.

Therefore, it will take the pump 30 minutes to transfer all 84 gallons of water out of the swimming pool.

Step-by-step explanation:

To determine the concession stand revenue, multiply the total collected revenue, $8250, by 45%, resulting in $3712.50 collected at the concession stand.

To calculate how much money the theater collected at the concession stand, we first need to find 45% of the total revenue of $8250.

Step 1: Convert the percentage to a decimal:

45% = 0.45

Step 2: Multiply the total revenue by the decimal:

$8250 * 0.45

Step 3: Perform the multiplication:

$8250 * 0.45 = $3712.5

Therefore, the theater collected $3712.50 at the concession stand last night.

To calculate David's unit rate of speed, divide the distance he traveled, 135 miles, by the time it took, 3 hours, which results in an average speed of 45 miles per hour.

The question concerns finding the unit rate of David's driving speed, which is a concept in mathematics related to distance and time. To find the unit rate of speed, we divide the total distance traveled by the total time taken. In this example, David drove 135 miles in 3 hours. Therefore, the unit rate (average speed) can be calculated as follows:

This means that David's average driving speed was 45 miles per hour.

Answer:

Marcia is correct.

Step-by-step explanation:

We are given that,

Rob states that 'all numbers have an even number of factors'.

Marcia states that 'some numbers have an odd number of factors'.

Let us consider the number 36. Now, it is given that,

1 × 36 = 36

2 × 18 = 36

3 × 12 = 36

4 × 9 = 36

6 × 6 = 36

Since, the repeated factor is counted only once. So, the factors of 36 are given by 1, 2, 3, 4, 6, 9, 12, 18 and 36.

This gives us that 36 has 9 factors and so, it has odd number of factors.

Hence, Marcia is correct.

The approximate perimeter of rectangle HJKL is 11.98 units.

Using the distance formula to find the lengths of the sides:

Distance between H and J = √[(x2 - x1)^2 + (y2 - y1)^2]

= √[(-2 - (-3))^2 + (1 - 2)^2]

= √[1^2 + (-1)^2]

= √2 ≈ 1.414

Distance between J and K = √[(-5 - (-2))^2 + (2 - 1)^2]

= √[(-3)^2 + (1)^2]

= √10 ≈ 3.162

Distance between K and L = √[(-6 - (-5))^2 + (-1 - 2)^2]

= √[(-1)^2 + (-3)^2]

= √10 ≈ 3.162

Distance between L and H = √[(-3 - (-6))^2 + (2 - (-1))^2]

= √[3^2 + (3)^2]

= √18 ≈ 4.243

Add the lengths of the sides to find the perimeter:

Perimeter = Length of HJ + Length of JK + Length of KL + Length of LH

Perimeter ≈ 1.414 + 3.162 + 3.162 + 4.243

Perimeter ≈ 11.98

Therefore, the approximate perimeter of rectangle HJKL is 11.98 units.

Answer:

Cafe A

1:10

5 free drinks

Cafe B

3:25

6 free drinks

Step-by-step explanation:

Cafe A

Cafe A offers 2 free bottled waters or juices for every 20 purchased. The ratio of free drinks to purchased ones is 2:20 = 1:10.

If you purchase 50 drinks, the free drinks will be:

50 purchased × (1 free / 10 purchased) = 5 free

Cafe B

Cafe B offers 3 free bottles waters or juices for every 25 purchased. The ratio of free drinks to purchased ones is 3:25.

If you purchase 50 drinks, the free drinks will be:

50 purchased × (3 free / 25 purchased) = 6 free

To figure out how many cups of milk are used for each cup of oatmeal, divide the amount of milk by the amount of oatmeal. The result is 2 1/2 cups of milk for each cup of oatmeal.

The question is asking us to figure out what the ratio of cups of milk to cups of oatmeal would be if it were reduced to one cup of oatmeal. The original proportions provided in the question are 8 3/4 cups of milk for 3 1/2 cups of oatmeal.

To find the answer, we would divide the amount of milk by the amount of oatmeal. First, we need to convert the mixed numbers to improper fractions. 8 3/4 is the same as 35/4 and 3 1/2 is the same as 7/2.

Then, we divide 35/4 by 7/2, which turns into a multiplication problem: 35/4 times 2/7. Keep in mind that multiplying fractions is straightforward - you simply multiply the numerators with numerators and denominators with denominators.

The result, therefore, becomes 70/28 which simplifies to 2.5 or 2 1/2 when turned back into a mixed number. So, there are 2 1/2 cups of milk used for each cup of oatmeal.

The horizontal distance between Point C (10, 3) and Point D (4, 3) is calculated by subtracting the smaller x-coordinate from the larger one. The result is 6 units.

The question is asking for the horizontal distance between two points on a coordinate plane, Point C (10, 3) and Point D (4, 3). In this context, the horizontal distance is the distance along the x-axis of the coordinate plane.

The x-coordinate of Point C is 10 and the x-coordinate of Point D is 4. To find the horizontal distance, we simply subtract the smaller x-coordinate from the larger one:

10 - 4 = 6

Therefore, the horizontal distance between Point C and Point D is 6 units.

In a coordinate plane, when two points share the same y-coordinate, the horizontal distance between them is the difference in their x-coordinates. For Point C(10, 3) and Point D(4, 3), the horizontal distance is 6 units.

The question you are asking relates to the concept of distance in a coordinate plane. In particular, you are looking at the horizontal distance between two points that share the same y-coordinate.

When the y-coordinates are the same, the horizontal distance between the two points is simply the difference in their x-values. So, if you have Point C located at (10, 3) and Point D at (4, 3), you can calculate the distance between them by subtracting the x-coordinate of Point D from the x-coordinate of Point C.

Therefore, the horizontal distance between Point C and Point D is 6 units.
