To find the percentage of yield in a calculator, you can follow these steps:
1. Determine the actual yield and the theoretical yield of the reaction. The actual yield is the amount of product that was actually produced in the reaction, while the theoretical yield is the amount of product that should have been produced based on the balanced chemical equation.
2. Divide the actual yield by the theoretical yield to find the decimal form of the percentage yield.
3. Multiply the decimal form of the percentage yield by 100 to find the percentage yield.
For example, if the actual yield of a reaction is 15 grams and the theoretical yield is 20 grams, the percentage yield would be:
(15/20) x 100 = 75%
Therefore, the percentage yield of the reaction is 75%.

Find the measure of missing angle
Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the most accurate rate of speed Morris is traveling?
1 mile = 5,280 feet
45 miles per hour
46 miles per hour
47 miles per hour
48 miles per hour
Answer:
48 miles per hour
Step-by-step explanation:
To convert Aneesha's speed from miles per hour to feet per second, we can use the formula:
speed in feet per second = speed in miles per hour * feet per mile / seconds per hour
So, Aneesha's speed in feet per second is:
50 miles per hour * 5,280 feet per mile / 3600 seconds per hour = 792 feet per second
Morris is traveling 3 feet per second less than Aneesha, so his speed in feet per second is:
792 feet per second - 3 feet per second = 789 feet per second
To convert Morris's speed back to miles per hour, we can use the formula:
speed in miles per hour = speed in feet per second * seconds per hour / feet per mile
So, Morris's speed in miles per hour is:
789 feet per second * 3600 seconds per hour / 5,280 feet per mile = approximately 48 miles per hour.

For a cardboard:
Area = (d) 8400 cm²Area in sqm = (b) 0.84 m(b) 3700 cm². (b) 4700 cm².(a) ₹11.75.How to calculate area and cost of painting?The area of the cardboard is:
Length = 1 m 5 cm = 105 cm
Breadth = 80 cm
Area = Length x Breadth = 105 cm x 80 cm = 8400 cm²
The area of the cardboard in square meters is:
1 m = 100 cm
Length = 1 m 5 cm = 105 cm = 1.05 m
Breadth = 80 cm = 0.8 m
Area = Length x Breadth = 1.05 m x 0.8 m = 0.84 m²
The area covered by the ribbons is the area of the cardboard that is not painted. From the previous calculations, we know that the area of the cardboard is 8400 cm² and the area that was painted is 4700 cm². Therefore, the area covered by the ribbons is:
Area covered by ribbons = Total area of the cardboard - Area that was painted
Area covered by ribbons = 8400 cm² - 4700 cm²
Area covered by ribbons = 3700 cm²
The area of the cardboard is (105 cm) x (80 cm) = 8400 cm².
The area covered by the ribbons is 3700 cm².
So, the area of the cardboard that was painted is 8400 cm² - 3700 cm² = 4700 cm².
The area of the cardboard is 8400 cm² or 0.84 m². The area covered by the ribbons is 3700 cm². So, the area that needs to be painted is the difference between the area of the cardboard and the area covered by the ribbons, which is:
8400 cm² - 3700 cm² = 4700 cm²
To convert to square meters, we divide by 10000:
4700 cm² ÷ 10000 = 0.47 m²
Therefore, the cost of painting the remaining area is:
0.47 m² × ₹25/m² = ₹11.75

How do you find the inverse of a modulo?
You need to find a number that, when multiplied by a given number modulo a certain value, produces a remainder of 1. This can be done using the extended Euclidean algorithm, and the resulting inverse is the residue of the coefficient modulo the modulus.
Finding the inverse of a modulo involves finding a number that, when multiplied by a given number modulo a certain value, produces a remainder of 1. This process is important in modular arithmetic, where calculations are performed with remainders of a fixed integer modulus.
To find the inverse of a modulo, you can use the extended Euclidean algorithm, which is a method for finding the greatest common divisor of two integers.
The steps for finding the inverse of a modulo are as follows:
1. Identify the number you want to find the inverse of (let's call it "a") and the modulus (let's call it "m").
2. Use the extended Euclidean algorithm to find the greatest common divisor of "a" and "m", and the coefficients x and y such that ax + my = gcd(a,m).
3. If gcd(a,m) = 1, then "a" has an inverse modulo "m" and the inverse is given by x mod m.
4. If gcd(a,m) is not equal to 1, then "a" does not have an inverse modulo "m".
In step 3, x mod m represents the residue of x modulo m, which is the unique non-negative integer less than m that is congruent to x modulo m. In other words, it is the remainder when x is divided by m.
For example, to find the inverse of 5 modulo 7, we can use the extended Euclidean algorithm to find that 2(5) + (-1)(7) = 1. Therefore, the inverse of 5 modulo 7 is 2.

At your floral business, you can sell 400 bouquets for a total benefit of $4,800. If you
earn $7,200 when selling 600 bouquets, what is your marginal benefit in this range?
The marginal benefit of selling one more bouquet within the range between 400 and 600 is $12.
How to find the marginal benefitTo find the marginal benefit in this range, we need to calculate the additional benefit of selling one more bouquet within this range.
First, let's find the benefit per bouquet in the range between selling 400 and 600 bouquets:
Total benefit in the range = $7,200 - $4,800 = $2,400
Number of bouquets in the range = 600 - 400 = 200
Benefit per bouquet in the range = Total benefit / Number of bouquets = $2,400 / 200 = $12
So for each bouquet sold within the range between 400 and 600, the benefit is $12.

The required, Mmusi borrowed R3000 from Aggie as per the given conditions.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan.
Amount = Principal [1 + rate×time]
Let's call the amount Mmusi borrowed from Aggie "P".
After two years, he has to pay back

At their old house they knew that the lawn was 10 ft by 20 ft. and needed 5 pounds of seed. Their new lawn is 100 # by 50 ft. How will knowing the amount of seed needed from their old house help them with Buying seed for the new lawn? How much will they need? Show all work
Answer: Seed needed for the new lawn = 125 pounds
Step-by-step explanation:
Knowing the amount of seed needed for their old lawn will help Mr. and Mrs. Quigley calculate the amount of seed needed for their new lawn based on the size of the area.
First, let's calculate the area of the old lawn:
Area = length × width
Area = 10 ft × 20 ft
Area = 200 square feet
Next, we can determine the seed requirement per square foot for the old lawn:
Seed requirement per square foot = total seed needed ÷ area of the lawn
Seed requirement per square foot = 5 pounds ÷ 200 square feet
Seed requirement per square foot = 0.025 pounds per square foot
Now, let's calculate the area of the new lawn:
Area = length × width
Area = 100 ft × 50 ft
Area = 5000 square feet
To find the amount of seed needed for the new lawn, we can multiply the seed requirement per square foot by the area of the new lawn:
Seed needed for the new lawn = Seed requirement per square foot × area of the new lawn
Seed needed for the new lawn = 0.025 pounds per square foot × 5000 square feet
Therefore, Mr. and Mrs. Quigley will need 125 pounds of grass seed for their new lawn based on the calculations using the information from their old lawn.

Due to inflation, a fixed quantity of money can buy 5% less every year. If camille has enough in her wallet to buy 86 movie tickets right now, how many movie tickets could the same amount of money buy in 4 years?.
Due to inflation, a fixed quantity of money can buy 5% less every year. If camille has enough in her wallet to buy 86 movie tickets right now, the same amount of money could buy 69 movie tickets in 4 years.
Inflation is the sustained increase in the general price level of goods and services in an economy over a period of time. When inflation occurs, each unit of currency buys fewer goods and services; consequently, inflation reduces the purchasing power of money. Here, inflation reduces the purchasing power of money by 5% every year.
Let's assume that Camille has enough in her wallet to buy 86 movie tickets right now. After 1 year, the same amount of money would be able to buy 86 * (100 - 5) / 100 = 81.7 movie tickets, since the purchasing power of the same amount of money would have decreased by 5%.
After 2 years, the same amount of money would be able to buy 81.7 * (100 - 5) / 100 = 77.6 movie tickets, since the purchasing power of the same amount of money would have decreased by another 5%.
After 3 years, the same amount of money would be able to buy 77.6 * (100 - 5) / 100 = 73.7 movie tickets, since the purchasing power of the same amount of money would have decreased by another 5%.
After 4 years, the same amount of money would be able to buy 73.7 * (100 - 5) / 100 = 69.9 movie tickets, since the purchasing power of the same amount of money would have decreased by another 5%.
However, since movie tickets cannot be bought in fractional amounts, we would round down to the nearest whole number, so the same amount of money could buy 69 movie tickets in 4 years.
