To find the amount of milk a cow can produce in 500 days at the rate of 2000 gallons every 365 days, you can set up a proportion and solve for x.

To find the amount of milk a cow can produce in 500 days at the rate of 2000 gallons every 365 days, we can set up a proportion. The correct proportion to use is:

365 days / 2000 gallons = 500 days / x gallons

To solve for x, we need to cross multiply and then divide:

365 * x = 2000 * 500

x = (2000 * 500) / 365

So the correct proportion to find x is 365 days / 2000 gallons = 500 days / x gallons.

Emma will need to invite 32 guests for both venues to cost the same amount, which will be $3,394 in total for either venue.

Emma is comparing the cost of two venues for her surprise party and wants to find out after how many guests the costs for both the venues will be the same, as well as the total cost at that point. To solve this, we can set up an equation where the total cost for both venues is equal, with x representing the number of guests.

Let's denote Hall A's cost with an initial reservation fee of $862 plus $76 per dinner as A(x), and Hall B's cost with an initial reservation fee of $894 plus $75 per dinner as B(x).

Therefore, we can write the following equation for the point where both costs are the same:

A(x) = B(x)

862 + 76x = 894 + 75x

After solving this equation for x, we find:

76x - 75x = 894 - 862

x = 32

So, Emma will have to invite 32 guests for the cost of both venues to be the same. At this number of guests, the total cost for either venue can be calculated:

Total cost for Hall A: 862 + 76(32) = $3,394

Total cost for Hall B: 894 + 75(32) = $3,394

Both venues will cost her $3,394 when hosting 32 guests.

Answer:

The total cost is $58.14.

Step-by-step explanation:

Given : A pair of shoes for $57 with a sales tax of 2%.

To find : What are two ways to find the total cost ?

Solution :

Cost price CP=$57

Sales tax S=2%

One way :

The total cost is given by,

[tex]C=CP+2\%\text{ of } CP[/tex]

[tex]C=57+\frac{2}{100}\times 57[/tex]

[tex]C=57+1.14[/tex]

[tex]C=58.14[/tex]

The total cost is $58.14.

Another way :

Using selling price formula,

[tex]SP=\frac{100+S\%}{100}\times CP[/tex]

[tex]SP=\frac{100+2}{100}\times 57[/tex]

[tex]SP=1.02\times 57[/tex]

[tex]SP=58.14[/tex]

The total cost is $58.14.

Answer

The owner lose is $100 .

Reason

As given

A man comes into a store and steals $100 from the register without the owner knowledge.

Comes back and buys $70 worth of stuff and the owner gives him $30 in change.

i.e First man steals $100  than give back to owner when he buys  $70 worth of stuff and  the owner gives him $30 in change.

Therefore the total owner lose is the sum of  $70 worth of stuff and  $30 in change.

Total owner lose = $70 + $30

                            = $100

Therefore the owner lose be  $100 .

To convert the insect's length from 3 inches to centimeters, multiply by the conversion factor of 2.54 to get 7.62 centimeters, which is the length to the nearest hundredth of a centimeter.

The student asked: An insect is 3 inches long what is the length to the nearest hundredth of a centimeter of the insect? To convert the insect's length from inches to centimeters, we need to use the conversion factor where 1 inch equals 2.54 centimeters.

First, we multiply the insect's length in inches by the conversion factor:

Therefore, the length of the insect is 7.62 centimeters when converted from inches and rounded to the nearest hundredth of a centimeter.

When measuring the length of small items like insects, it is important to choose an appropriate tool and unit for precision. In this case, a ruler that includes both inches and centimeters would be appropriate for measuring an insect of this size. The centimeter, being smaller than the inch and equivalent to 10 millimeters, offers the precision needed for such measurements.

Ответ: Вася получил тройку на втором уроке.

The number of tiles along the edge of a square room with a hundred square tiles is 10.

First, we need to recognize that a square room means all sides are of equal length. Since the room is tiled with square tiles throughout, the number of tiles along one edge will be the same as the other.

If there are a hundred square tiles in total, this represents the area of the square which is the product of the lengths of its sides (since the area of a square is given by side x side).

To find the length of a side, we take the square root of the total number of tiles. In this case, the square root of 100 is 10.

Therefore, there are 10 tiles along the edge of the square room.

Jupiter is 34.023 AU closer to the Sun than Pluto. This is obtained by subtracting Jupiter's distance from the Sun (5.2 AU) from Pluto's distance from the Sun (39.223 AU).

Distance in space can often be measured in Astronomical Units (AU), which is the average distance from Earth to the Sun. Given that Jupiter is 5.2 AU from the Sun, and Pluto is 39.223 AU from the Sun, you want to find out how much closer to the Sun Jupiter is than Pluto.

To get this, you simply subtract Jupiter's distance from Pluto's distance. That is, 39.223 AU (Pluto's distance) - 5.2 AU (Jupiter's distance).

The outcome of this calculation is 34.023 AU, which means that Jupiter is 34.023 AU closer to the Sun than Pluto.

Final answer:

Jupiter is 34.023 AU closer to the Sun than Pluto, which is calculated by subtracting Jupiter's distance from Pluto's distance.

Explanation:

Distances in space can be measured using the astronomical unit (AU), where 1 AU is approximately 150 million kilometers, the average distance from Earth to the Sun. To find out how much closer Jupiter is to the Sun than Pluto, we subtract the distance from the Sun to Jupiter from the distance from the Sun to Pluto. Given that Jupiter is 5.2 AU from the Sun and Pluto is 39.223 AU from the Sun:

Distance difference = Pluto's distance - Jupiter's distance

= 39.223 AU - 5.2 AU

= 34.023 AU

Therefore, Jupiter is 34.023 AU closer to the Sun than Pluto.

In the given equation P-2+qp, when you substitute p=7 and q=4, the final result calculated is 33.

The given equation is P-2+qp. In this expression, we are to use p=7, and q=4. Substituting these values in our equation, it becomes: 7 - 2 + 7 * 4. Now, let's simplify it further step by step. First, calculate the multiplication: 7 * 4 = 28. So, the expression becomes 7 - 2 + 28. Now, perform the addition and subtraction: 7 + 28 = 35; and then 35 - 2 equates to 33. So, when you plug p = 7 and q = 4 into the equation P-2+qp, the result is 33.
