Greg started to run on a treadmill after setting it’s timer for 98 minutes the display says that he has finished 57% of his run how many minutes have gone by
A total of 55.86 minutes have gone by since Greg started his run on the treadmill.
How many minutes have gone byIf Greg has completed 57% of his run, it means he has 43% of his run remaining.
To find out how many minutes have gone by, we can use proportions.
Let's say x is the total number of minutes Greg needs to complete his run:
x = 57% * 98 minutes
Evaluate
x = minutes
Therefore, approximately 55.86 minutes have gone by since Greg started his run on the treadmill.

Use quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)
x = [ 4 ± √(16 − 24) ] / 6
x = [ 4 ± √(-8) ] / 6

A soil element in the field has various complicated stress paths during the lifetime of a geotechnical structure. The behaviour of this soil can be predicted under more realistic field conditions. Briefly discuss simulation field conditions in the laboratory using shear strength test.
The simulation of field conditions in the laboratory using shear strength tests allows for the prediction of soil behavior under realistic stress paths. This involves subjecting the soil element to various complex stress paths that it would experience during the lifetime of a geotechnical structure.
In shear strength testing, the laboratory conditions are designed to mimic the field conditions as closely as possible. This includes replicating the stress levels, stress paths, and boundary conditions that the soil would encounter in the field. The laboratory setup typically involves a shear box or a triaxial apparatus, where the soil sample is confined and subjected to controlled loading.
To simulate realistic field conditions, different types of stress paths can be applied during the shear strength testing. This could involve cyclic loading to simulate the effect of repeated loading and unloading, as well as different combinations of vertical and horizontal stresses to replicate the stress paths experienced by the soil in the field. The testing can also consider time-dependent effects, such as creep and consolidation, which influence the long-term behavior of the soil.
By simulating field conditions in the laboratory through shear strength testing, engineers and researchers can better understand the behavior of soil under realistic stress paths. This information is crucial for designing geotechnical structures that can withstand the complex and varied stress conditions they may encounter in the field.

given : a₁ = 1₁ 9₂ = 2₁ an = da n-1 Find lim anth n-700 am ta n-2
The limit of anth/n-700 as n approaches infinity is equal to the limit of am/n-2 as n approaches infinity. This is because the sequence an is defined recursively as an = da n-1, where d = 2. Therefore, an is a geometric sequence with first term 1 and common ratio 2.
The limit of a geometric sequence is equal to the first term divided by 1 - the common ratio, so the limit of an as n approaches infinity is 1/(1-2) = -1. The limit of a sequence is the value that the sequence approaches as the number of terms tends to infinity. In this case, we are interested in the limit of anth/n-700 as n approaches infinity.
We can rewrite anth/n-700 as am/n-2, because an = da n-1. Therefore, we need to find the limit of am/n-2 as n approaches infinity.
The sequence am/n-2 is a geometric sequence with first term 1 and common ratio d = 2. The limit of a geometric sequence is equal to the first term divided by 1 - the common ratio, so the limit of am/n-2 as n approaches infinity is 1/(1-2) = -1.
Therefore, the limit of anth/n-700 as n approaches infinity is also equal to -1.

triangle abc is congruent to triangle def . which statement must be true about the triangles? ab=ef ab=de m∠a=m∠e m∠b=m∠d
If triangle ABC is congruent to triangle DEF, then all four statements must be true about the triangles: AB=EF, AB=DE, ∠A=∠E, and ∠B=∠D.
When two triangles are congruent, it means that they have the same size and shape. To show that triangle ABC is congruent to triangle DEF, we need to show that all corresponding sides and angles are equal.
The statement AB=EF means that the lengths of side AB and EF are equal. Similarly, the statement AB=DE means that the lengths of side AB and DE are equal.
The statement ∠A=∠E means that angle A in triangle ABC is equal to angle E in triangle DEF. Similarly, the statement ∠B=∠D means that angle B in triangle ABC is equal to angle D in triangle DEF.
By the Congruence of Triangles axiom (SSS), if two triangles have three sides of equal length, then they are congruent. Therefore, since AB=EF, AB=DE, and ∠A=∠E, we can conclude that triangle ABC is congruent to triangle DEF.
Furthermore, since ∠B=∠D, we can conclude that all four statements (AB=EF, AB=DE, ∠A=∠E, and ∠B=∠D) must be true in this case.

g A student council consists of 15 students. (a) How many ways can a committee of five be selected from the membership of the council
There are 3,003 ways to select a committee of five from the 15 students in the student council.
To calculate the number of ways to select a committee of five from a group of 15 students, we can use the combination formula. The formula for combination, denoted as "n choose r," calculates the number of ways to choose r items from a set of n items without considering the order.
In this case, we want to choose a committee of five from a group of 15 students. Using the combination formula, we can calculate it as:
C(15, 5) = 15! / (5! * (15-5)!)
where "!" denotes factorial. Simplifying the expression:
C(15, 5) = 15! / (5! * 10!)
The factorial of a number is the product of all positive integers less than or equal to that number. In this case:
15! = 15 * 14 * 13 * 12 * 11 * 10!
Cancelling out the common terms:
C(15, 5) = (15 * 14 * 13 * 12 * 11) / (5 * 4 * 3 * 2 * 1)
Simplifying the expression further:
C(15, 5) = 3,003
Therefore, there are 3,003 ways to select a committee of five from the 15 students in the student council.

The ratios of successive numbers in the Fibonacci sequence eventually get closer to a. 1.61
In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2.
The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1 (0, 1, 1, 2, 3, 5, 8, 13, ...). When you take the ratio of successive numbers in the sequence (e.g., 5/3 or 8/5), it converges to approximately 1.618, also known as the Golden Ratio or Phi.

the population of a city decreases by 3.8% per year. what should we multiply the current population by to find next year's population in one step?
To find next year's population in one step, the current population should be multiplied by 0.962. This value is obtained by subtracting 3.8% from 100% (1) and converting it to a decimal form (0.962).
1. Multiplying the current population by this factor accounts for the decrease of 3.8% and gives an estimate of the population for the next year.
2. To calculate next year's population in one step, we need to consider the decrease of 3.8% per year. When a population decreases by a certain percentage, we can express it as a decimal value by subtracting that percentage from 100%. In this case, subtracting 3.8% from 100% gives us 96.2%. To convert this to a decimal form, we divide it by 100, resulting in 0.962.
3.By multiplying the current population by 0.962, we take into account the decrease of 3.8% and estimate the population for the next year. This approach assumes a consistent decrease rate over time. For example, if the current population is 100, multiplying it by 0.962 would yield an estimated next year's population of 96.2.
