Step-by-step explanation:

Answer: a. 10%

Step-by-step explanation:

Girls in the class = 40%

Girls play tennis = 25%

Percentage of class play tennis = 40%*25% = 0.4*0.25 = 0.1

Percentage of class play tennis = 10%

The percentage of the class that plays tennis is 70%.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying by 100.

The percentage change is also calculated using the same method.

In percentage change we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We

If 40% of a class is girls, then 60% of the class must be boys.

Let's say there are 100 students in the class, so 40 of them are girls, and 60 are boys.

If 25% of the girls play tennis, that means 25% of 40, which is 10 girls, play tennis.

Therefore, the total number of students who play tennis is 10 girls + some number of boys.

We don't know how many boys play tennis, but we can find out what percentage of the whole class plays tennis by dividing the total number of tennis players by the total number of students:

(10 girls + X boys) / 100 total students

We know that 40% of the class is girls, so:

X boys = 60% of 100 total students = 60 students

So the total number of students who play tennis is:

10 girls + 60 boys = 70 students

And the percentage of the class that plays tennis is:

70 students / 100 total students = 70%

Therefore,

The percentage of the class that plays tennis is 70%.

Answer:

Step-by-step explanation:

yes it is a factor because 31 is a factor and if u add there is a one

Final answer:

Yes, 3 is a factor of 81 because the sum of 81's digits (8 and 1) is 9, which is divisible by 3. Also, since 81 is 3 raised to the power of 4, 3 is repeatedly a factor of 81.

Explanation:

To determine if 3 is a factor of 81, we can use the concept of divisibility. A number is divisible by 3 if the sum of its digits is divisible by 3. The number 81 only consists of the digits 8 and 1, and when added together (8 + 1), they equal 9. Since 9 is divisible by 3, so is 81. Therefore, 3 is indeed a factor of 81.

Additionally, the three-factor product rule can confirm this, as combining the factors 3, 3, and 3 (since 3 x 3 x 3 = 27, and 27 x 3 = 81), you end up with 81, which proves that 3 is a factor of 81.

Answer:

T_12 = 5(T_3)

Step-by-step explanation

T_17 = 13(T_2)

T_n = a + (n-1)d; where a=first term and d=common difference

T_17 = a + 16d

T_2 = a + d

Therefore,

a + 16d = 13(a + d)

a + 16d = 13a + 13d

16d - 13d = 13a - a

3d = 12a

d = 4a

To prove that T_12 = 5(T_3)

a + 11d = 5(a + 2d)

a + 11d = 5a + 10d

since d = 4a

a + 11(4a) = 5a + 10(4a)

a + 44a = 5a + 40a

45a = 45a

Since  LHS = RHS

Therefore; T_12 = 5(T_3)

Answer:

75%

Step-by-step explanation:

42/56 = [tex]\frac{42}{56}[/tex]

Convert to decimal form:

42÷56 = 0.75

= 75%

Darren got 75% of the questions correct on his test, as 42 out of 56 simplifies to 3/4 or 75%. This percentage might place him in a higher percentile, indicating good performance.

Darren scored 42 out of 56 questions correctly on his test. To find what percent of the questions he got correct, you set up a fraction of correct answers over the total number of questions and then convert it to a percentage. The fraction for Darren's test is 42/56, which simplifies to 3/4 or 0.75 when divided. To convert this to a percentage, you multiply by 100, giving Darren a score of 75% correct on his test.

Some students might be interested in how this compares to percentile ranks. For example, if the 70th percentile for a test is 16 correct answers out of 20, this means that 70% of the students answered 16 or fewer questions correctly. Darren's score of 75% would likely place him in a higher percentile since he got a larger proportion of the questions correct, which is generally considered good.

The correct answer is option 1: x = -4y+19

Step-by-step explanation:

Given equations are:

[tex]3x+2y=17\ \ \ Eqn1\\x+4y=19\ \ \ \ Eqn2[/tex]

When we have to solve a system of equations using substitution method we look for a variable in both of equations that is without any co-efficient as it is easy to isolate that variable in the equation and then using substitution method to solve it

We can see that in equation 2, x is without any co-efficient

So,

[tex]x+4y = 19[/tex]

Subtracting 4y from both sides

[tex]x+4y-4y = 19-4y\\x = 19-4y\\[/tex]

Can also be written as:

Answer:

Step-by-step explanation:

To find the terms of the sequence substitute n = 1, 2, 3, 4, 10 into the rule.

n = 1 → 2(1)² = 2(1) = 2

n = 2 → 2(2)² = 2(4) = 8

n = 3 → 2(3)² = 2(9) = 18

n = 4 → 2(4)² = 2(16) = 32

n = 10 → 2(10)² = 2(100) = 200

The first 4 terms are 1, 8, 18, 32 and the 10 th term is 200

2, 8, 18, 32.

10th term =  200.

Step-by-step explanation:

The first 4 terms of 2n^2 are

2(1)^2,  2(2)^2,   2(3)^2, 2(4)^2

Answer:

First of all, before writing the y-intercept you need to make sure that the equation is in slope intercept form.

x + 3y = 14

3y = 14 - x

y = 14/3 -x/3

y= -x/3 + 14/3

                         14/3 is the y-intercept

The y-intercept of the line with equation x + 3y = 14 is 4.67.

The equation of the line is in the form x + 3y = 14. To find the y-intercept, we need to set x = 0 and solve for y. Plugging in x = 0, we get 0 + 3y = 14. Simplifying the equation gives us 3y = 14. Dividing both sides by 3, we find that y = 4.67. Therefore, the y-intercept of the line is 4.67.

The weekly income y of a real estate agent can be calculated using the equation y = 250 + 0.02x where 'y' is the weekly income, 'x' is the sales amount, '250' is the fixed salary and '0.02x' is the commission on sales.

The weekly income y of a real estate agent is comprised of a fixed salary and a variable part which is a commission based on the amount of sales done. Given the fixed salary is $250 and the commission is 2% of sales, we can represent this as a mathematical equation:

y = 250 + 0.02x

Here, 'y' represents the weekly income, 'x' represents the amount of sales and '250' is the fixed salary. The term '0.02x' is the 2% commission of sales. So, for a given sales amount 'x', the weekly income 'y' can be computed using this equation.

Step-by-step explanation:

Total Money Needed = $850

Each Golf Ball = $2

Total Balls needed = 850/2 = 425 balls

Case = 24 Pack

Pack = 6 balls

So a Case has:

24 * 6 = 144 balls

They need 425 balls to sell and each case has 144 balls, so number of case needed would be:

425/144 = 2.95

We can't have 2.95 cases, so we round up to 3 cases

45 adult tickets and 80 children tickets were sold

Solution:

Let "a" be the number of adult tickets sold

Let "c" be the number of children tickets sold

Cost of 1 adult ticket = $ 6

Cost of 1 children ticket = $ 3.50

They sold a total of 125 tickets

Therefore,

a + c = 125

c = 125 - a --------- eqn 1

They made a total of $550. Therefore, frame a equation as:

number of adult tickets sold x Cost of 1 adult ticket + number of children tickets sold x Cost of 1 children ticket = 550

[tex]a \times 6 + c \times 3.50 = 550\\[/tex]

6a + 3.50c = 550 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

6a + 3.50(125 - a) = 550

6a + 437.5 - 3.50a = 550

2.5a = 112.5

Substitute a = 45 in eqn 1

c = 125 - 45

Thus 45 adult tickets and 80 children tickets were sold

The number Fred thinks of is 111

Solution:

Given that, Fred thinks of a number that is greater than 110 and less than 120

He can make his number with same number of hundreds,tens and ones

To find: Fred's number

Given that the number is greater than 110 and less than 120

The possible numbers are:

111 , 112, 113, 114, 115, 116, 117, 118, 119

But he can make his number with same number of hundreds,tens and ones

So the numbers in ones, tens and hundreds place are same

So the only possible number is 111

Thus the number Fred thinks of is 111

Final answer:

Fred's number is 111, as it is the only number that is greater than 110 and less than 120 and has the same number of hundreds, tens, and ones.

Explanation:

The number Fred thinks of must be greater than 110 and less than 120. Additionally, it must have the same number of hundreds, tens, and ones. To meet these conditions, the only number that fulfills this is 111. This is because it's the only number between 110 and 120 that has the same digit in the hundreds, tens, and ones place.

Fred's number is unique in this range because it is represented with three identical digits, showcasing an interesting property of numbers in our base-ten system where a digit's value depends on its position. Hence, 111 is the number Fred is thinking of, which consists of one hundred, one ten, and one one.
