what is 820 divided by 42

To determine how many more items Home Room B needs to collect to have more items per student, we can find the average number of items per student in Home Room A and multiply it by the number of students in Home Room B.

To determine how many more items Home Room B needs to collect to have more items per student, we need to compare the number of items collected by Home Room B with the number of items collected by Home Room A per student.

Let's assume Home Room A has 20 students, so they collected a total of 21 additional items of food. We can calculate how many items were collected per student in Home Room A by dividing the total number of items (21) by the number of students (20).

Now, let's assume Home Room B has 30 students. To find out how many more items Home Room B needs to collect, we need to multiply the number of students in Home Room B by the average number of items per student in Home Room A. This will give us the total number of items Home Room B needs to collect to have more items per student.

Let's calculate:

Therefore, Home Room B needs to collect 31.5 more items to have more items per student.

The question lacks essential details, such as the initial number of items collected and the number of students in each home room, which are necessary to calculate the number of additional items home room B needs to collect.

The question seems to be missing specific information about how many items were initially collected by home room A and B, and the number of students in each home room. Therefore, without the provided information, it's not possible to calculate how many more items home room B needs to collect. Usually, to solve such a problem, you would take the total number of items collected by home room A, add 21 to it, then figure out the current items per student ratio for both home rooms A and B. Home room B would need to collect enough items to exceed that per student ratio. If further details are available, please provide them to support an accurate calculation.

To represent the number of gallons of water in the tub after x minutes, the equation y = 30 - 6x can be used.

The question asks us to write an equation that represents the number of gallons of water in the tub after a certain number of minutes. Let's break down the information given:

We can use this information to find the rate at which the bathtub is draining. To do this, we'll subtract the amount of water after 5 minutes from the amount after 2 minutes to get the change in water: 30 gallons - 12 gallons = 18 gallons. This means the tub is draining 18 gallons over a span of 3 minutes, which is equivalent to a rate of 6 gallons per minute.

Now, we can write the equation that represents the number of gallons of water in the tub after x minutes. Let y represent the number of gallons, and x represent the number of minutes. We can use the equation y = 30 - 6x, where 30 is the initial amount of water in the tub at 2 minutes, and 6x is the amount of water drained over x minutes at a rate of 6 gallons per minute.

The area of a rectangular room is 143 square feet.

To find the area of a rectangular room, we multiply the length by the width.

However, since the measurements are given in different units (feet and inches), we need to convert them to the same unit first.

Convert the width from inches to feet.

Since there are :

12 inches= 1 foot, we divide 132 inches by 12:

132 inches ÷ 12

= 11 feet

Now we have the dimensions in feet:

13 feet (length) by 11 feet (width).

Calculate the area by multiplying the length by the width:

Area = 13 feet × 11 feet

= 143 square feet

Therefore, the area of the room is 143 square feet.

Final answer:

Drawing a model to show the relationship between feet and inches involves using the conversion factor between these units (1 foot = 12 inches) and applying scales for practical conversions, such as the examples of Asharah and Kenya's model cars, which translate real-life measurements into manageable sizes for scale models.

Explanation:

To draw a model that shows the relationship between feet and inches, particularly in the context of scale models as mentioned in the examples of Asharah and Kenya's model cars, you would first identify the conversion factor between feet and inches, which is 1 foot equals 12 inches. The scales given for the models represent this relationship in a condensed form tailored to small, manageable models of larger objects.

These examples illustrate how to create a simple model or drawing that demonstrates the relationship between two different units of measurement by using scale factors.

To maintain an equivalent ratio of sugar to milk when increasing a recipe, multiply both the sugar and milk amounts by the same factor. For example, multiplying by 5 results in a ratio of 15 tablespoons of sugar to 10 tablespoons of milk.

If Mark is using a ratio of 3 tablespoons of sugar to 2 tablespoons of milk in a recipe and decides to increase the recipe, we need to maintain the same ratio for any quantity. An equivalent ratio can be found by multiplying both parts of the original ratio by the same number. For example, if Mark wanted to double the recipe, he would use 6 tablespoons of sugar and 4 tablespoons of milk (3 x 2 = 6 and 2 x 2 = 4), keeping the same ratio of 3:2.

To increase the recipe to any desired amount, Mark could use a conversion factor. For instance, if the original recipe makes 1 batch and Mark wants to make 5 batches, he multiplies both parts of the ratio by 5. The new ratio would be 15 tablespoons of sugar to 10 tablespoons of milk, as 3 x 5 = 15 and 2 x 5 = 10. This maintains the sweetness and consistency of the recipe across a larger volume.

Beethoven was a renowned composer who struggled with hearing loss later in his life. Please  note that he did not erase his music deliberately.

Instead, due to his deafness, he often revised and edited his compositions repeatedly, writing and rewriting sections to perfect his musical ideas.

Beethoven was known for his meticulous nature and pursuit of musical excellence. He constantly refined his compositions, making changes, corrections, and improvements until he was satisfied with the final piece. This process involved extensive revisions and alterations to his musical scores, which might have been mistakenly perceived as "erasing" music.

The factored form of the expression 16a + 10 is 2(8a + 5).

To factor the expression 16a + 10, we can divide each term by the greatest common factor (GCF) of the expression.

The GCF of 16a and 10 is 2, so we can divide each term by 2 to get:

16a + 10 = 2(8a + 5)

Therefore, the factored form of the expression 16a + 10 is 2(8a + 5).

Final answer:

Michelle used 70 beads to make her 14-inch long necklace, as determined by solving the equation 1/7b + 4 = 14 and isolating the variable b.

Explanation:

The question asks us to solve for the number of beads, b, in a necklace that is 14 inches long. The equation given is 1/7b + 4 = 14. We need to solve for b.

To solve for b, we first subtract 4 from both sides of the equation to get 1/7b = 10. Next, we multiply both sides by 7 to isolate b on one side of the equation, which gives us b = 70. Therefore, Michelle used 70 beads for her necklace.

Answer:

What the ratio tells us is that for every 2 inches that fall in January, 5 are predicted to fall for the entire winter.

For this problem we can cross multiply (if you haven't done this yet, just let me know and i can edit this answer to do the problem a different way)

We set the equation up to compare the two ratios with X representing the predicted total snowfall

Now, we multiply the value on the top of the first fraction by the value on the bottom of the second fraction and vice versa

2X=5*34

Now, we can simplify

2X=170

Now, we can divide by 2 on both sides in order to get X alone

X=85

So, the predicted snowfall for the winter is 85 inches

Answer : The ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

Step-by-step explanation : Given,

Number of members voted for pizza = 6

Number of members voted for chicken = 10

Number of members voted for hot dogs = 20 - (10 +6) = 4

Now we have to determine the ratio represents the number of votes for hot dogs to chicken.

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{4}{10}[/tex]

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{2}{5}[/tex]

Thus, the ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

To find the current price of the comic book, subtract the total decrease from the initial price and then add the total increase. The current price is $8.22.

To find the current price of the comic book, we need to look at how the price has changed over the last 4 months. The table shows that the price decreased by $2.36 in the first month, then increased by $1.07 in the second month, and finally increased by $2.14 in the third month. Since the price started at $7.37, we can calculate the current price by subtracting the total decrease from the initial price and then adding the total increase.

So, the current price is $7.37 - $2.36 + $1.07 + $2.14 = $8.22.

This answer is reasonable because it falls between the lowest and highest prices in the table and follows the pattern of the price changes over the last 4 months.

The student needs the price changes from a table to calculate the current price of a comic book from its starting price of $7.37, but the table data is not provided. We would need that information to give a precise answer.

The student is asking about the change in price of an item, specifically a comic book called Painted Tiger, Volume 1, that started at $7.37, over the course of 4 months. However, the question doesn't provide the actual table with the price changes. To accurately answer this question, we would need the specific price changes listed in the table to calculate the current price of the comic. Without this information, we cannot provide an exact answer.

If we had the information, typically, we could determine the current price by applying the changes in price over time to the original price. These changes might be increases or decreases that are either flat amounts or percentages. For example, if in month one the price increased by 10%, we would calculate the new price by multiplying the original price of $7.37 by 1.10. If the next month the price decreased by $2, we would subtract $2 from the previously calculated new price. We would repeat this process using all the price changes mentioned in the table to find the final price.

Since the necessary data from the table is missing, you should either provide the price change information or consult the original source to get the current price of Painted Tiger, Volume 1. Once you have those figures, consider the direction and amount of each price change to ensure that the final calculation makes sense; the price should reasonably follow the trends indicated by the table.

Answer:

7 friends got pizza

Step-by-step explanation:

Tom ate [tex]\frac{1}{4}[/tex] of a pizza.

So, Reaming part = [tex]1-\frac{1}{4}=\frac{3}{4}[/tex]

He divided the leftover pizza into pieces each equal to 1/12 of the original pizza.

Let x be the no. of grinds he gave 1/12 part pieces

So, Part of pizza given to x friends = [tex]\frac{1}{12}x[/tex]

So, Remaining pizza = [tex]\frac{3}{4} -\frac{1}{12}x[/tex]

We are given that 1/6 of the original pizza remained.

So, [tex]\frac{3}{4} -\frac{1}{12}x =\frac{1}{6}[/tex]

[tex]x=7[/tex]

Hence 7 friends got pizza

Final answer:

The product of 29/2 sec and 60 MB/sec is 870 MB. This calculation is based on simple multiplication and the result is considered reasonable for the given data transfer rate.

Explanation:

The question asks for the product of 29/2 seconds and 60 MB/sec. To calculate this, we perform the multiplication of the two quantities, which gives us:

(29/2 seconds) × (60 MB/sec) = (29/2) × 60 MB = (29 × 30) MB = 870 MB.

This result represents the amount of data transferred in 29/2 seconds at a rate of 60 MB/sec, which is 870 MB. We also check if the result is reasonable by comparing it to familiar units of data transfer, and 870 MB seems reasonable for a data transfer rate of 60 MB/sec over approximately 14.5 seconds.
