Answer:
314 mStep-by-step explanation:
the diagonal is the hypotenuse of the two triangles that form the rectangle (see figure) we solve with Pythagoras
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
a² = b²+ c²
a² = 250² + 190²
a² = 62500 + 36100
a² = 98600
a = √98600
a = 314 m
Canon borrows $3,000 at a yearly simple interest rates of 1.6% for 2 years how much does he owe in interest and how much does he need to pay back in all
Answers
Interest is Rs.96 and Total amount payback is Rs.3096.
Principal (P) = Rs.3000
Rate of interest (R) = 1.6%
Number of years (N) = 2 yrs
Simple interest = PNR/100
= (3000*1.6*2)/100
=(9600/100
=96Rs
Total Amount (A) = P+I
=3000+96
=3096Rs
The principal, or initial balance of your account, is where interest is calculated. This could be the initial sum of a loan or an investment. The simplest way to compute interest is as a percentage of the principal .Only relatively short-term loans frequently include one-time basic interest charges. Interest is frequently paid on a daily, monthly, quarterly, or annual basis for loans with longer terms. In that scenario, interest would be consistently earned.
Hence, the interest for the above principle is 96Rs and the total amount to be payback is 3096Rs.

In a shipment of 53 vials, only 13 do not have hairline cracks. if you randomly select 2 vials from the shipment, what is the probability that none of the 2 vials have hairline cracks?
Answers
Calculating the likelihood of experiments happening is one of the branches of mathematics named as probability. The probability that none of the 2 vials have hairline cracks is 0.0565.
What is meant by probability?The study of probabilities, which exists defined by the ratio of favorable occurrences to probable cases, exists comprehended as probability.
The probability that there won't be any hairline cracks = 13/53
If you choose two vials at random from the delivery
Probability (avoiding hairline cracks) = 13 - 1/53 - 1
Probability (avoiding hairline cracks) = 12/52
To find the chance that neither of the two vials has a hairline crack is
(13/53) × (12/52) = 0.2452 × 0.2307
= 0.0565

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Given that,
Andrew ran 5 miles less than two times the number of miles Bernadette ran.
If Bernadette ran x miles then,
13 = 2x - 5 is the correct representation.
Now,

Step-by-step explanation:
f(x) = 5|x - 1| - 5
f(x) will be positive that means >= 0, if
5|x - 1| - 5 >= 0
5|x - 1| >= 5
|x - 1| >= 1
that will be true for x <= 0 or x >= 2
f(x) will be negative for the other cases.
so, 0 < x < 2
f(x) is increasing in

the value "1" is for sure included, as it starts the increasing part.
f(x) is decreasing in

Two men are pushing a broken down car, mass 1800 kg, along a horizontal road with a combined horizontal force of 1000n. at one instant the car accelerates at 0.25m/s^". what is the value of frictional force acting on car at instant
Answers
When 2 men pushes car with mass 1800 kg and their combined horizontal forces are 1000 N, then frictional force acting on the car is 550 N.
The situation can be depicted in the attached picture. F1 and F2 are the horizontal forces of both men, while Fr is the frictional force. Remember that a frictional force is always the opposite of the direction of velocity.
Apply the 2nd Newton law of motion:
∑F = m.a
Where:
∑F = resultant of forces
m = mass of object
a = acceleration
In this situation, ∑F = F1 + F2 - Fr
The given parameters:
m = 1800 kg
a = 0.25 m/s²
F1 + F2 = 1000 N
Substitute these parameters into the 2nd Newton law:
F1 + F2 - Fr = m.a
1000 - Fr = 1800 . (0.25)
1000 - Fr = 450
Fr = 1000 - 450 = 550 N

Two angles form a linear pair. The measure of one angle is 1/3 the measure of the other angle
Answers
Answer:
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so alinear pair of angles must add up to 180 degrees
So, x + y = 180
x = 1/3(y)
1/3(y) + y = 180

How to determine the family of constants associated to non-real roots of a quadratic equation
The nature of the roots of quadratic equations of the form a · x² + b · x + c = 0 can be inferred by the understading of its discriminant under the following condition:
b² - 4 · a · c < 0
Where a, b, c are the coefficients of the polynomial.
If we know that a = 2 · q, b = q and c = - 1, then the equation of the discriminant is:

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
An equiangular triangle is a triangle whose all angles are the same and since all angles are the same so by geometrical constraint all sides must be the same so it will also be an equilateral triangle.
In an equilateral triangle, all interior angles are 60°, and since an acute angle triangle is a triangle in which all angles must be less than 90°.

A scatter plot is a series of points plotted on horizontal and vertical axes. If there is no correlation between variables, the points appear randomly scattered on the coordinate plane. The points will be clustered around a straight line if the correlation is high. A scatter chart is a data visualization tool that helps show trends.
The scatter plot shows not only the magnitude of the correlation but also the direction of the correlation.
As the vertical (or Y-axis) variable increases, the correlation is positive as the horizontal (or X-axis) variable increases.
The correlation is negative if the y-axis variable decreases and the x-axis variable increases, or vice versa.
The correlation is zero if none of the above criteria can be established.
