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.
Explanation: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:
Number of items per student in Home Room A = 21 / 20 = 1.05 items per studentNumber of items Home Room B needs to collect = 30 * 1.05 = 31.5 itemsTherefore, 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.
Explanation: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.
Explain how the areas of a triangle and a parallelogram with the same base and height are related
The area of a triangle is half the area of a parallelogram with the same base and height because a triangle's area is calculated using half the product of its base and height, while a parallelogram's area is the full product of its base and height.
The areas of a triangle and a parallelogram with the same base and height are related in that the area of the triangle is exactly half the area of the parallelogram. To understand this, recall that the area of a parallelogram is calculated by multiplying its base by its height ( extit{Base x Height}). A triangle sharing the same base and height will have half the area because the area of a triangle is given by half the product of its base and height ( extit{0.5 x Base x Height}).
Let's say we have a parallelogram and a triangle with the same base 'b' and height 'h'. The area of the parallelogram is extit{b x h}, while the area of the triangle will be extit{0.5 x b x h}. This relationship can be visualized by drawing a diagonal across the parallelogram, which cuts it into two equal triangles, each having the same area as the original triangle we're comparing it to.

Dakota had a kite with 25 6/12 string.The kite got stuck in a tree.she lost 4 3/12 feet of string trying to free it.how much string does Dakota still have?
Final answer:
After subtracting the lost string (4 3/12 feet) from the initial length (25 6/12 feet) and simplifying, Dakota is left with 21 1/4 feet of kite string.
Explanation:
To calculate the amount of kite string Dakota has left after losing some, we need to perform a subtraction operation involving mixed numbers. Initially, Dakota had 25 6/12 feet of kite string. When Dakota's kite got stuck, she lost 4 3/12 feet of string.
First, let's simplify the mixed numbers by converting them to improper fractions. To do this, multiply the whole number by the denominator and add the numerator. So, 25 6/12 becomes (25 × 12) + 6 = 300 + 6 = 306/12. Similarly, 4 3/12 becomes (4 × 12) + 3 = 48 + 3 = 51/12.
Now subtract the lost string from the initial length: 306/12 - 51/12 = 255/12. Finally, we convert this back to a mixed number by dividing the numerator by the denominator: 255 ÷ 12 = 21 with a remainder of 3, which gives us 21 3/12 feet of string, or 21 1/4 feet when simplified.
Therefore, Dakota now has 21 1/4 feet of kite string left.

How old am I if 400 reduced by 2 times my age is 244?
If 400 reduced by 2 times your age is 244, you will be 78 years old. This conclusion was reached by solving the equation 400 - 2x = 244, where x represents the unknown age.
Explanation:To solve the problem given, you need to work with the equation provided: 400 decreased by 2 times your age is 244. In mathematical terms, this can be written as 400 - 2x = 244, where 'x' represents your age.
Next, you need to solve for 'x'. The first step is to isolate 'x' by moving terms around. Add 2x to both sides to get 400 = 244 + 2x and then subtract 244 from both sides to get 156 = 2x. You finish the process by dividing both sides by 2, which gives you x = 78. Therefore, if 400 reduced by 2 times your age is 244, you are 78 years old.

The electronics store is having a sale on video games. The regular price for a video game is $42.90. Michael bought three games at the sale price and paid $90.09. What percent discount did he receive?
Answer:
i might be wrong but the answer is A
Step-by-step explanation:
A computer software store is having a sale. The table shows the regular price r and the sale price s of various items. Which formula can be used to calculate the sale price?
Final answer:
The formula to calculate the sale price of items on sale is s = r - (r × discount rate), where 's' is the sale price, 'r' is the regular price, and the discount rate is expressed as a decimal. An example illustrates the process for a $100 item with a 20% discount, resulting in a sale price of $80.
Explanation:
Generally, the sale price can be calculated by subtracting the discount amount from the regular price. The discount amount itself is often a percentage of the regular price. Therefore, if the discount rate is given as a percentage, the formula to find the sale price could be expressed as s = r - (r × discount rate). This is a simplification and assumes that the discount rate needs to be converted from a percentage to a decimal form before applying.
For example, if an item's regular price is $100, and there is a 20% discount, the calculation would be: s = 100 - (100 × 0.20) = $80. Hence, the sale price is $80. This formula is crucial for both customers and businesses to understand how much they save or earn respectively on sale items.

I have $100 which I wish to buy exactly 100 animals to feed to my snake. succulent mice cost $5, large Juicy fresh cockroaches are $1, and imported flies are $0.05 each .if I spend every cent buying these animals and I buy at least one of each how many cockroaches will I buy?
The number of co.ck.roaches that one can buy is given as: 95
It is to be noted that this was solved using the knowledge of Algebraic Equations.
An algebraic equation is one where two mathematical statements are equated to one another. See how we arrive at the answer using algebra statements below.
What is the solution to the question?Let us set the
Number of Mice to X Number of Co.ck.roaches to Y; andNumber of Flies to Z.Note that the total money required for the snake's food is thus given as:
X + Y + Z = 100.................................A
5X + Y + 0.05Z = 100 .......................B
To remove the decimals in B, we multiply same both sides of the equation by 20 to get:
100X + 20Y + Z = 2,000 ........................C
Recall that the number of each animal purchased must ≥ 1
Since we are looking at the number of co.ck.roaches, let us set
X = 1
Z = 1
This gives us:
100 + 20Y + 1 = 2,000
Thus
20Y = 2,000-100-1
Y = 1899/20
Y = 94.95
Hence the answer is approximately 95 co.ckroaches.

The county fair charges 1.00 per ride and additional 3.00 to get in. Write an equation to represent the total cost of attending the fair
Final answer:
The total cost of attending the fair with an access fee and a per-ride charge is represented by the equation C = 3 + 1 × x, where x is the number of rides taken.
Explanation:
To calculate the total cost of attending the county fair which includes an access fee and a per-ride charge, we can write an equation where x represents the number of rides a person takes. The access fee is a fixed cost of $3.00, and the per-ride cost is $1.00. Therefore, if a person takes x rides, the total cost C can be represented by the equation:
C = 3 + 1 × x
For example, if the person takes 5 rides, we would calculate the total cost as 3 + 1 × 5 = $8.00.
