The required age for Emma and her sister is 26 years and 15 years respectively.

Given that,
The sum of Emma’s age and her sister's age is 41 years. Emma is 11 years older than her sister.

The problem given is of arithmetics.

Let the age of Emma be x and her sister be y.

The sum of Emma’s age and her sister's age is 41 years.
x + y = 41   - - - - - - (1)

Emma is 11 years older than her sister
x = y + 11  - - - - - (2)

Solving equations 2 and 1
y + 11 + y = 41
2y = 30
y = 15
Now,
Put y in equation 1.
x = 41 - 15
x = 26

Thus, the required age for Emma and her sister is 26 years and 15 years respectively.

Answer:

375 seconds.

Step-by-step explanation:

Step 1

The first step is to find the Circumference of the paddle.

The Circumference of a paddle = Circumference of a circle = 2πr or πD

Where D = Diameter of the circle or Diameter of the paddle

In the question above,

Diameter of a paddle = 8 feet

Circumference of the paddle= πD

= π × 8

= 25.132741229 feet

Step 2

We have to find out first, the time it would take for the paddle to complete one revolution.

This is calculated using the formula:

Time(t) = distance travelled ÷ Speed travelled by the fins along the outer edge of the paddle

In the question,

Speed travelled by the fins along the outer edge of the paddle = 6.7 feet per second

It is important to note that the distance travelled is = Circumference of the paddle = 25.132741229 feet

Time taken to complete one revolution = 25.132741229 feet ÷ 6.7 feet per second

Time taken to complete one revolution. = 3.7511554073 seconds

Approximately = 3.75 seconds.

Step 3

If , 1 full revolution of the paddle takes = 3.75 seconds

100 revolutions =

100 × 3.75 seconds

= 375 seconds.

Therefore, it takes the paddle wheel 375 seconds to complete 100 full revolutions.

Answer:

Mean is 69.8

Median is 77

Range is 54

Step-by-step explanation:

Mean is all numbers added up, then divided by the amount of numbers.

Median is the middle number of all numbers (To find this you put all numbers in order from least amount to highest amount, then you find the most center number of the rest).

Range is the highest number subtracted from the lowest number.

Answer:

Mean:  69.8

Range:  54

Median:  77

Step-by-step explanation:

The mean is the average of the numbers.  The range is the largest number minus the smallest number.  The median is the middle number.

The mean is 69.8.

[tex]\frac{45 + 83+45+77+99}{5} \\\frac{349}{5}\\69.8[/tex]

The range is 54.

99 - 45 = 54

The median is 77.

Now, let's find the slope of the two coordinates. We are going to use the rise over run method.

-2 -6 /1 - -3 = -8/4

-8/4 = -2

Answer:

(9 / 10) * PI radians = .9 * PI = 2.8274333882  radians

Sector Area = Central Angle in Radians / 2 * radius^2

Sector Area = 2.8274333882  / 2 * 5 * 5

Sector Area = 1.4137166941  * 25

Sector Area = 35.3429173525

Using degrees:

Sector Area = (162 degrees / 360) * PI * radius ^2

Sector Area = .45 * PI * 25

Sector Area = 35.342917352

22 pencils

Step-by-step explanation:

it would be 28 pencils all together, minus 6 would be 22 pencils

Ashton had 28 pencils initially and after giving 6 away to his brother, he was left with 22 pencils.

Ashton had two boxes of pencils with fourteen pencils in each box, which means he had a total of 2 x 14 = 28 pencils.

After giving six pencils to his brother, Ashton would have 28 - 6 = 22 pencils left.

Therefore, Ashton had 22 pencils after giving some to his brother.

Final answer:

Abigail and Monique can spend a maximum of $40 together for renting a boat. Given the company's pricing model, the inequality 3h ≤ 27 represents their situation, and solving it shows they can rent the boat for up to 9 hours.

Explanation:

The question is about calculating the maximum number of hours Abigail and Monique can rent a boat, given they each do not want to spend more than $20. The company charges a $13 flat fee plus $3 per hour for renting a boat. The total amount they are willing to spend each is $40 ($20 each), subtracting the flat fee leaves $27 to be spent on the hourly rate. Therefore, the inequality to find the maximum number of hours they can rent the boat is:

3h ≤ 27

Dividing both sides by 3 gives:

h ≤ 9

So, Abigail and Monique can rent a boat for a maximum of 9 hours.

The diameter of a circle with a circumference of 11.4mm is approximately 3.63mm when rounded to three significant figures. The formula for calculating the diameter is D = C/π, where C is the circumference.

The student is asking how to find the length of the diameter of a circle if the circumference is given as 11.4mm. To find the diameter, we can use the formula for the circumference of a circle, which is C = πD, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and D is the diameter. Rearranging the formula to solve for the diameter, we get D = C/π.

Substitute C with 11.4mm into the equation:

D = 11.4mm /π

Using a calculator:

D ≈ 11.4mm / 3.14159

D ≈ 3.63mm (rounded to three significant figures)

Therefore, the diameter of the circle is approximately 3.63mm when rounded to three significant figures.

Step-by-step explanation:

Y - intercept = (0 , -4)

X - intercept = (4/3 , 0)

You only need these two points and then you get a linear function.

First to find y-intercept, the (x) value has to be 0. So substitute 0 for (x).

You get 3-6(0)+2y=-5

now solve that. you get 3-0+2y=-5

= 3+2y=-5

= 2y = -8

= y = -4

Knowing that y = -4, x = 0. You have a point now. (0 , -4 )

Do the same for x - intercept, but this time (y) = 0. So you would get

3 - 6x + 2(0) = -5

= 3 - 6x + 0 = -5

= 3 - 6x = -5

= -6x = -8

= x = 8/6

which is app = to 4/3

Answer:

The perimeter would be 60 units; Option B

Step-by-step explanation:

~ Let us consider this problem. We know that tangent segments are congruent to one another provided they are from one endpoint. According to that, we would note that several segments are congruent to one another...  ~

1. All the tangent segments that "sprout" from one vertex in this plane onto the circle circumscribed in this triangle are congruent, as noted before. According to that the side of the length 18 units has one part equivalent to 8.7 units.

2. With that being said the other part of the side with length 18 units, would be 18 - 8.7 = 9.3 units. Respectfully the side with length of 21.3 units has a part that is congruent to 9.3, by tangent ≅. This other part of the side with 21.3 units now = 21.3 - 9.3 = 12 units. Similarly the side with 8.7 as a part of it, has the other part ≅ to 12 units, it's measure thus also being 12 units.

3. Let us see the measures we have at this point. The perimeter would be ⇒ 8.7 + 8.7 + 9.3 + 9.3 + 12 + 12 = 60 units

If the probability of an event is 0, it is impossible to happen, in contrast to an event with a probability of 1, which is certain to happen. Probability is measured between 0 (impossible event) and 1 (certain event), with a familiar example being a coin flip where each outcome (heads or tails) has an equal probability of 0.5.

If the probability of a chance event is 0, it is impossible for it to happen when compared to a chance event with a probability of 1, which is certain to happen. The concept of probability is expressed as a number between zero and one, inclusive. An event with a probability of 0 is not expected to happen at all, while an event with a probability of 1 is considered an absolute certainty. In contrast, if two events are mutually exclusive, the probability that they both happen at the same time is zero (P(A AND B) = 0). A familiar example involving probability is flipping a fair coin, where there's a 1/2 chance of getting heads, meaning that the outcome of getting either heads or tails are equally likely; each has a probability of 0.5.
