According to the given statement the a wire rope sling with a strength of 10,000 pounds and a total working load of 2,000 pounds has a design factor of 5.

Dividing the ultimate (or maximum) stress by both the normal (or working) stress yields a relatively simple equation to determine FoS. A structure but rather component with an FoS of 1 will fail precisely when it meets the design load and is unable to support any extra load.

A wire rope sling, for example, with such a strength exceeding 10,000 pounds (4,545 kilograms) and a total process load of 2,000 pounds (909 kilograms), has a design factor (multiplier) of 5. Currently available wire rope slings have a design factor of 5.

In order to take into account uncertainty regarding the load, the structural qualities, or both, a design factor1 is a tolerance added to a load and structural strength. Design considerations have typically been applied to the size of the load while designing oilfield casing.

So Katya needs 21.42 gallons of gas for 600 miles.

A Linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

Given we have Katya have to take a trip for 600 miles.

Let x be number of gallons of gas y be number of miles driven by Katya

We have an relation from table that 28X = Y and Y we have from table 600

So 28X = 600 and [tex]X = \frac{600}{28}[/tex]

X= 21.42 gallons .

Step-by-step explanation:

First of you're going to combine liked terms, (5t+3t) to get 8t. You want to get t isolated so you're going to divide it by 8 to get t by itself, you are also going to do 100 divided by 8 because to remain equal you have to do the math on both sides.

The population of town Vic is greater than population of town Val by 52000 .

In the question ,

it is given that

the population of town Val = 8x10³

the population of town Vic = 6x10⁴

Rewriting both the numbers we get

population of town Val = 8x1000 = 8000

population of town Vic = 6x10000 = 60000

It can be clearly seen that 60000 > 8000

So the population of Vic > population of Val

To calculate the difference subtract the population of Val from population of Vic .

Substituting the values of population we get ,

difference = 60000 - 8000

= 52000

Therefore , the population of town Vic is greater than population of town Val by 52000 .

Answer:

a. 105 and 115 employees

b. 185 employees

c. 20 years

Step-by-step explanation:

The total of employees at any given year is y

x is the number of year

then y = 85 + 10x

a. 2nd year: y = 85 + 10(2) = 85 + 20 = 105

  3rd year: y = 85 + 10(3) = 85 + 30 = 115

b. 10th year: y = 85 + 10(10) = 85 + 100 = 185

c: if y = 285

285 = 85 + 10x

10x = 285 - 85

10x = 200

The commutative property apply to compositions of f(x) and g(x) when f(g(x)) and g(f(x)) are equal for all values of x.

The commutative property says that  [tex]a*b=b*a[/tex] , for any binary operation [tex]'*'[/tex]. These binary operations can be addition, multiplication, function composition, etc. But subtraction and division does not follow commutative property.

Here the operation is composition of two functions defined as,

Then the function composition has commutative property when

That is, when f(g(x)) = g(f(x))

Coordinate plane is the answer of this problem.

A Coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis

We have been given real numbers A number is real that has no imaginary part the set of all real numbers comprises the rational and the irrationals.

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

The Midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

We have been given that two numbers are 10 units away in different directions from their midpoint, m, on a number line.

The two numbers that are 10 units away indifferent directions would be (m - 10) and(m+10).

The product of both number would be(m -10)(m + 10) .

Since the product of both numbers is -99, so we can represent this information in an equations (m -10)(m + 10) = -99.

A parallelogram is a quadrilateral with four interior angles and four sides, whose opposite angles are equal to each other.

In the image given:

Angle A = 120°

Since ABCD is a parallelogram, therefore, the angle that is opposite to angle A would also be 120°. Therefore:

Angle C = 120°

Angle D = 180 - 120 = 60°.

Angle DCO = 1/2(angle C) = 1/2(120) = 60°

Angle CDO = 1/2(angle D) = 1/2(60) = 30°

x = 180 - m<DCO - m<CDO [triangle sum theorem]
