Answer:

I got 4 hours and 16 minutes

Step-by-step explanation:

I divided the amount of money he has ($26) to the amount it takes to rent for one hour ($6.25). To make it more simple you could just say 4 hours worth of rent.

Answer:

Step-by-step explanation:

Since Kevin only has $26 and the bicycle rends for $6.25 per hours this means that:

6.25h ≤ 26

Where h represents hours $6.25 is the slope (rate) at which Kevin is being charged and $26 is the amount of money he has.

By solving for the inequality above we obtain:

[tex]6.25h\leq 26\\\\\fra{6.25h}{6.25}\leq \frac{26}{6.25}\\\\h\leq4.16[/tex]

This means that Kevin can ride the bike for less than or equal to 4.16 hours.  Now that means 4 hours and 16% of an hour, let's calculate what 16% of an hour is equal to.  Since we know that there are 60 minutes in an hour and 16% is 0.16 (since 16÷100=0.16) in decimals we obtain:

60×0.16=9.6 minutes

This means 9 minutes and 60% of a minute, so we will calculate how much is 60% of a minute:

60×.6=36 seconds

Therefore, Kevin can ride this bike for less than or equal to 4 hours 9 minutes and 36 seconds.

Answer:

26 most years; 27 some years

Step-by-step explanation:

1 day out of 14 is 1/14 of the number of days in a year.

The number of days in a year depends on the year or years you're talking about. In all cases, there are not an integer number of weeks in a year, so days are left over. 365/14 = 26 1/14.

For example, if you're concerned with every other Monday, most years, there will be 26 of them, but every few years there will be 27. Over a period of 800 years, there will be exactly 71 years with 27 days of interest instead of 26. 800 is not divisible by 71, so the spacing will be uneven.

Answer:

2+√3

Step-by-step explanation:

We know that roots with square roots come in pairs

so if we have a+ sqrt(b), we will also have a - sqrt(b)

Since one of the roots is 2 -sqrt(3), it must have another root of 2+ sqrt(3)

The conjugate of the root (2-√3) for a polynomial with integer coefficients is (2+√3), which must also be a root of the polynomial.

If (2-√3) is a root of a polynomial with integer coefficients, then by the Conjugate Root Theorem (which is a consequence of the Complex Conjugate Root Theorem), if the polynomial has real coefficients and a non-real root, then its complex conjugate must also be a root. However, since √3 is a real number and our expression involves only real numbers, in this context, we look for the conjugate in terms of radicals. Thus, the conjugate of (2-√3) would be (2+√3), which must also be a root of the polynomial.

The other options given, such as 2√3, √3-2, and 3-√2, do not satisfy the criteria of being the conjugate of (2-√3). They might be roots of some polynomial, but without the constraint of integer coefficients or known conjugate pairs, we cannot confirm that.

Final answer:

To convert 8 3/4% to a fraction, you transform the mixed number into an improper fraction, which equals 875%. Then, scale it by dividing by 100 to get 8.75%, and express this as 8.75/100. Simplify by dividing numerator and denominator by 25 to finally get 7/16.

Explanation:

To express 8 3/4% as a fraction, we first convert the mixed number to an improper fraction. There are 4 quarters in a whole, so 8 3/4 is the same as 8 + 3/4, which equals 35/4. To convert this into a percent, we need to consider that 1 whole is the same as 100%, so 35/4 as a percent is 35/4 * 100%. Simplifying this, we multiply 35 by 25 (100% divided by 4), which gives us 875%. Since we want to express 8 3/4%, not 800 3/4%, we divide by 100 to get back to the correct scale. So, 875% divided by 100 is 8.75%, which is the same as 8 3/4%.

Now, to convert 8.75% to a fraction, we can write it as 8.75/100. To simplify this fraction, we recognize that both the numerator and the denominator are divisible by 25. Dividing both by 25, we get 7/4 divided by 1 which simplifies to 7/4 divided by 100/25. This simplifies to 7/4 * 25/100, which equals 7/16 when simplified.

Thus, 8 3/4% as a fraction is 7/16.

Answer:

Step-by-step explanation:

If you work through a series of obscure calculations involving area and the radius of the incircle, they boil down to a simple fact:

... For MN║BC, perimeter ΔAMN = perimeter ΔABC - BC = AB+AC

.. = 17+24 = 41

_____

Wow! Thank you for an interesting question with a not-so-obvious answer.

_____

A little more detail

The point I that you have defined is the incenter—the center of an inscribed circle in the triangle. Its radius is the distance from I to any side, such as BC, for example.

If we use "Δ" to represent the area of the triangle and "s" to represent the semi-perimeter, (AB+BC+AC)/2, then the incircle has radius Δ/s. The area Δ can be computed from Heron's formula by ...

... Δ = √(s(s-a)(s-b)(s-c)) . . . . where a, b, c are the side lengths

For this triangle, the area is Δ = √38480 ≈ 196.1632 units². That turns out to be irrelevant.

The altitude to BC will be 2Δ/(BC), so the altitude of ΔAMN = (2Δ/(BC) -Δ/s). Dividing this by the altitude to BC gives the ratio of the perimeter of ΔAMN to the perimeter of ΔABC, which is 2s.

Putting these ratios and perimeters together, we get ...

... perimeter ΔAMN = (2Δ/(BC) -Δ/s)/(2Δ/(BC)) × 2s

... = (2/(BC) -1/s) × BC × s = 2s -BC

... perimeter ΔAMN = AB +AC

The perimeter of triangle AMN is found using the angle bisector theorem to determine the lengths of AM and AN, and recognizing that MN = BC due to the parallelism. After calculating, the approximate perimeter of triangle AMN is found to be 54.86.

In triangle ABC, the angle bisectors BD and CE intersect at I. A line through I parallel to BC intersects AB at M and AC at N. Perimeter of triangle AMN is found by adding lengths AM, MN, and NA. Since IM is parallel to BC and bisectors divide the angles proportionally, we have:

AM/AB = AI/AD, where D is the intersection of angle bisector BD with BC.

AN/AC = AI/AD, using similar logic.

MN is parallel to BC, so MN = BC due to the properties of parallelograms.

Using AB = 17, AC = 24, and BC = 33, find AM and AN using the proportional segments:

AM = (AI/AD) * AB

AN = (AI/AD) * AC

The perimeter of triangle AMN is AM + MN + AN.

To solve for AI/AD, we use the angle bisector theorem which gives us AI/AD = AB/BC = 17/33. Substituting this into the equations for AM and AN we get:

AM = (17/33) * 17

AN = (17/33) * 24

Computing these we find:

AM = 8.77 (approximately)

AN = 13.09 (approximately)

Lastly, we add AM, AN, and BC to find the perimeter:

Perimeter = AM + AN + MN

Perimeter = 8.77 + 13.09 + 33 = 54.86 (approximately)

This is the approximate perimeter of triangle AMN.

Answer:

option no D

Step-by-step explanation:

AS it given that it is a random generator

so it will generate random integers between 1 and 3

so

possible sample space = {1,2,3}

Total no of out comes = 3

Estimated probability that 3 will occur will be obtained by dividing total no of outcomes with total no of possible events to occur

as the occurrence of event is only 1

so

Estimated probability = 1 /3 = 0.33333

Now

The experiment is performed

total outcomes = 14

Total no of like able events that 3 occurred = 4

Actual probability = 4 / 14

                             = 0.2857

Difference between actual and estimated probability is = 0.3333-0.2857

                                                                                            =0.0421

                                                                                           ≅0.04

which is option D

Final answer:

The actual probability of a 3 being generated is 1/3, and the estimated probability from the given sequence is 4/14. The difference between the two probabilities is roughly 0.05, which corresponds to answer choice C.

Explanation:

The question refers to the probability of a random generator selecting the number 3 from a set of integers ranging from 1 to 3, where each number has an equal chance of being selected. The actual probability of the random generator selecting a 3 is 1/3, as there are three possible outcomes and each is equally likely. To find the estimated probability, we can look at the frequency of the number 3 in the provided set of generated numbers: (1 2 3 3 3 2 2 1 1 1 2 3 1 1). In this set, there are 4 occurrences of the number 3 out of 14 total numbers. Therefore, the estimated probability is 4/14 or approximately 0.2857. The difference between the estimated and actual probabilities is 0.3333 (actual) - 0.2857 (estimated) = 0.0476. When rounded to two decimal places, the difference is approximately 0.05. Thus, the correct answer to the question would be C. 0.05.
