Answer: After 20 days
Step-by-step explanation: you have to find the greatest common multiple so that the number is a multiple for each of them
since 10 is multiple of 5 you have to find the lcm of 10 and 4 or 5 and 4 which is still 20
so just multiply them and if she swims and does cycles every 10 days then you know that if she is swimming she is cycling, but if she is cycling she might not be swimming. So if running is 4 days then just multiply 4*5 = 20

A paddle wheel on a boat is 8 feet in diameter. The fins along the outer edge travel at a speed of 6.7 feet per second. How long does it take the paddle wheel to complete 100 full revolutions? Round to the nearest second.
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.

If the probability of a chance event is 0, it is _________ to happen when compared to a chance event with a probability of 1.
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.

a circle with radius 5 has a sector with a central angle of 9/10pi radians what is the area of the sector
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

A company charges $13 plus $3 per hour to rent a boat. Abigail and Monique want to rent a boat but do not want to spend more than $20 each. Which inequality below would represent how to find the maximum number of hours the girls can rent a boat?
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.
A terrarium is built in the shape of a triangular prism. The prism is 10 inches in height and contains 450 cubic inches of space. A triangular prism is shown. The prism is 10 inches in height and contains 450 cubic inches of space. What is the area of the base shape of the prism? square inches
Answer:
45 square inches
Step-by-step explanation:
We are told that a terrarium is constructed in a triangular prism shape with the following 10 inches tall and 450 cubic inches in volume.
We are asked to calculate the area of the base shape of the prism, we know that the volume of any triangular prism is equal to the area of the base times the height therefore:
450 = W × 10
we solve for A:
A = 450/10
A = 45
Which means that the base area is 45 square inches
Answer:
(C) 45 square inches

Ashton had two boxes of pencils with fourteen pencils in each box. He gave six pencils to his brother. How many pencils did Ashton have left?
Answer:
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.

The sum of the geometric sequence can be found by plugging the values into the formula S_n = a * (1 - r^n) / (1 - r) and calculating it using a graphing utility.
Explanation:The question pertains to finding the sum of a geometric sequence using a graphing utility. The general formula to find the sum of a geometric sequence is S_n = a * (1 - r^n) / (1 - r) where S_n is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms. In your case, our first term a is 15, common ratio r is 5, and number of terms n is 6.
Now, you need to plug these values into the formula and compute the sum. Here's how: S_6 = 15 * (1 - 5^6) / (1 - 5). Solve this equation using your graphing utility to get the sum of the sequence. Remember to round off to three decimal places as needed.

Find the perimeter of each polygon. Assume that lines which appear to be tangent are tangent.
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

children who visited Mrs. Jones's home were
wearing a costume?
A. 20
B. 50
C. 69
D. 80
E. 92
ANSWER. BBB
Step-by-step explanation:
Mrs. Jones gave candy bars to 80 children who were wearing costumes. The correct answer is option D.
The question is a classic example of a system of equations problem
Let's call the number of children with costumes x and the number without costumes y. We have two pieces of information that will help us solve for x:
The total number of children is 100, so x + y = 100.
The total amount of money spent on candy is $69, and since candy bars cost $0.80 and gummies cost $0.25, we can express this as 0.80x + 0.25y = 69.
We can solve this system of equations using substitution or elimination method.
Let's use substitution and express y in terms of x from the first equation: y = 100 - x.
Now we substitute this into the second equation:
0.80x + 0.25(100 - x) = 69
0.80x + 25 - 0.25x = 69
0.55x = 44
Solving for x gives us x = [tex]\frac{44}{0.55}[/tex]
Therefore, 80 children wearing costumes were given candy bars by Mrs. Jones. The correct answer is D.

the circumference of a circle is 11.4mm. find the length of the diameter. give your answer rounded to 3SF.
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.
Explanation: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.

Which points are on the graph of the equation 3-6x+2y=-5
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
