If the sum of two numbers is 196 and one number is 20% more than the other number, what are the numbers?

18 percentage of all customers prefer sport drinks and tea.

Let's start by finding the total percentage of customers who prefer sport drinks:

55% prefer soft drinks, which means 100% - 55% = 45% prefer sport drinks.

Next, we need to find the percentage of sport drink customers who also prefer tea:

61% of those who prefer sport drinks also prefer coffee, which means 100% - 61% = 39% prefer tea.

Finally, we can calculate the percentage of all customers who prefer sport drinks and tea:

The percentage of customers who prefer sport drinks is 45%.

Of those sport drink customers, 39% also prefer tea.

Therefore, the percentage of all customers who prefer sport drinks and tea is 45% * 39% = 17.55%, which rounds up to 18%.

So, approximately 18% of all customers prefer sport drinks and tea. Therefore, the answer is 18% (rounded to the nearest whole percentage).

Answer:

it is actually 39%

Step-by-step explanation:

I took the test and got it right.

This is why

55% prefer soft drinks, so 100 - 55 is 45%, which is how many people prfer sport drinks.

61% prefer coffee over tea of the 45% that prefer sport drinks.

we want to know the percentage that prefer sport drinks and tea so we subtract 100 - 61 to get 39%

That is the answer, 39%

3.33 is the final value of the given expression.

To simplify this expression, we first need to change the subtraction of a negative to an addition. We can do this by remembering the rule that says "Subtracting a negative is the same as adding a positive."

So, -2 1/3 - (-5) becomes -2 1/3 + 5.

Now, we need to convert the mixed number -2 1/3 to an improper fraction.

-2 1/3 is the same as -7/3, because 2 times 3 is 6, plus 1 is 7, and the denominator stays the same.

Therefore, -2 1/3 + 5 becomes -3+1/3

Answer:

Step-by-step explanation:

We can use the ratios of similar triangles to solve this problem. Let's call the height of the tree "h". Then, we have two similar right triangles:

Kaylee's triangle: the height is 1.45 meters, the length of the shadow is 34.2 meters, and the angle between the height and the shadow is theta.

Tree's triangle: the height is h meters, the length of the shadow is 39.55 meters, and the angle between the height and the shadow is also theta.

Using these two triangles, we can set up the following proportion:

h / 39.55 = 1.45 / 34.2

Cross-multiplying, we get:

h * 34.2 = 39.55 * 1.45

Simplifying:

h = (39.55 * 1.45) / 34.2

h = 1.68176

So the height of the tree is approximately 1.68 meters (to the nearest hundredth of a meter).

7(3x + 2) - 11x > 54

To solve the inequality 7(3x + 2) - 11x > 54, we need to simplify and isolate the variable on one side of the inequality sign.

First, we distribute the 7 on the left side:

21x + 14 - 11x > 54

Next, we combine like terms:

10x + 14 > 54

Then, we subtract 14 from both sides:

10x > 40

Finally, we divide both sides by 10:

x > 4

Therefore, the solution to the inequality 7(3x + 2) - 11x > 54 is x > 4.

The mathematical expectation of the number of games played in this series is 4 games.

The mathematical expectation of the number of games in a series where the first team to win 4 games is declared the winner can be calculated using probability theory. Each game has a 50% chance of being won by either team, assuming the teams are evenly matched. Therefore, the probability of one team winning the series in exactly 4 games is (1/2)^4 or 1/16. The probability of one team winning the series in exactly 5 games is the probability of losing the first game and then winning the next four games or winning the first game and then winning three of the next four games. This can be calculated as (1/2)^5 * (4 choose 1) + (1/2)^5 * (4 choose 3) or 5/16. Similarly, the probabilities of one team winning the series in exactly 6, 7 or 8 games can be calculated as 10/32, 10/64 and 5/256 respectively. Therefore, the mathematical expectation of the number of games is the sum of the products of the number of games and their corresponding probabilities. This is (4*1/16) + (5*5/16) + (6*10/32) + (7*10/64) + (8*5/256) which simplifies to 33/8 or approximately 4.125 games.
The situation you described is a classic example of a negative binomial distribution. In this case, the winner of the series will be the first team to win 4 games. To find the mathematical expectation (mean) of the number of games played, we can use the formula for the negative binomial mean:

Mean = (r * (1-p))/p

Where "r" is the number of successes (4 wins) and "p" is the probability of success (0.5, since the teams are evenly matched).

Mean = (4 * (1-0.5))/0.5 = (4 * 0.5)/0.5 = 4

So, the mathematical expectation of the number of games played in this series is 4 games.

We have,

To find out how many loaves of bread can be made, we need to divide the total amount of dough by the amount of dough needed for each loaf.

The bucket contains 1 2/3 pounds of dough, which we can rewrite as an improper fraction:

1 2/3 = (3 x 1 + 2)/3 = 5/3

So, the bucket contains 5/3 pounds of dough.

Each loaf requires 4/5 of a pound of dough.

To find the number of loaves that can be made, we need to divide the total amount of dough by the amount of dough per loaf:

Number of loaves = Total amount of dough / Amount of dough per loaf

Number of loaves = (5/3) / (4/5)

To divide by a fraction, we can multiply by its reciprocal:

Number of loaves = (5/3) x (5/4)

Number of loaves = 25/12

Since we cannot make a fraction of a loaf, we need to round the result up to the nearest whole number.

Therefore,

To calculate the simple interest rate of the promissory note, we need to determine the total interest paid over the course of the 24 payments.

The total amount to be repaid is 24 x $56.25 = $1350.

The total interest paid is $1350 - $1250 = $100.

The simple interest rate can be calculated using the formula:

Simple Interest = (Total Interest / Principal) x (100 / Time)

where Principal is the amount borrowed, Time is the time period in years, and we multiply by 100 to express the interest rate as a percentage.

In this case, the Time period is 2 years (24 payments of 1 month each).

So, the simple interest rate is:

(100 / 1250) x (100 / 2) = 4%

Therefore, the answer is option (d) 4%.

The area of the regular hexagon is approximately 428.5 cm².

The segment a that is drawn from the center of the polygon perpendicular to one of its sides is called the apothem.

To find the area of the polygon, we can use the formula:

Area = (1/2) × apothem × perimeter

We know that the apothem (a) is 7√3 cm and the side length (s) is 14 cm. To find the perimeter, we need to know how many sides the polygon has. Let's assume that it is a regular hexagon (a polygon with six sides), since that is a common shape.

The perimeter of a regular hexagon with side length s is given by:

Perimeter = 6s

Substituting s = 14 cm, we get:

Perimeter = 6(14) = 84 cm

Now we can plug in the values for apothem and perimeter into the formula for area:

Area = (1/2) × a  Perimeter

= (1/2) × 7√3 cm × 84 cm

≈ 428.5 cm²

Rounding to the nearest tenth and including the correct units, the area of the regular hexagon is approximately 428.5 cm².

24.5 gallons of milk

Step-by-step explanation:

To calculate the total amount of milk needed daily, we need to find the total amount of milk consumed by all the students and convert it into gallons.

For grades 1 through 3, the total amount of milk consumed daily at lunch is:

12 fl. oz. x 212 students = 2,544 fl. oz.

For breakfast:

6 fl. oz. x 48 students = 288 fl. oz.

For kindergarten snack time:

8 fl. oz. x 38 students = 304 fl. oz.

Adding up all these amounts gives us the total amount of milk consumed daily:

2,544 fl. oz. + 288 fl. oz. + 304 fl. oz. = 3,136 fl. oz.

To convert this to gallons, we need to divide by 128 (the number of fluid ounces in a gallon):

3,136 fl. oz. ÷ 128 = 24.5 gallons (rounded to the nearest tenth)

Therefore, Chef needs approximately 24.5 gallons of milk daily to serve all the students.

The probability that the essay contains a grammar mistake or a spelling mistake is 11/32

To find the probability that an essay contains a grammar mistake or a spelling mistake, we need to add the probabilities of the essay containing only a grammar mistake, only a spelling mistake, and both a grammar and spelling mistake.

Let's first find the probability of an essay containing only a grammar mistake. From the given information, we know that 1/5 of the mistakes on the essays are grammar mistakes. So, the probability of an essay containing only a grammar mistake is

1/5 - 1/12 = 7/60

The subtraction of 1/12 is necessary because we don't want to count the mistakes that are both grammar and spelling mistakes twice.

Similarly, the probability of an essay containing only a spelling mistake is:

1/8 - 1/12 = 5/96

Again, we subtract 1/12 because we don't want to count the mistakes that are both grammar and spelling mistakes twice.

Finally, the probability of an essay containing both a grammar and spelling mistake is

1/12

Now, we can add these probabilities to find the probability that an essay contains a grammar mistake or a spelling mistake
