The safe load, L of a wooden a beam 3 in. wide 9 in. deep and 11 ft long of the same material support is 307.17

Analyzing the given conditions in the question, we get

The safe load, L is directly proportional to width (w) and square of depth (d²)

also,

L is inversely as length (l) i.e L = k/l

combining the above conditions, we get an equation as:

L = k(wd²/l)

now, for the first case we have been given

w = 8 in

d = 6 in

l = 10 ft

L = 1966 lbs

thus,

1966 lb = k ((8 × 6²)/10)

or

k = 68.26 lbs/(ft.in³)  

Now,

Using the calculated value of k to calculate the value of L in the second case  

in the second case, we have

w = 3 in

d =9 in

l = 11 ft

Final Safe load L' =  68.26 × (6 × 3²/12)

or

L' =307.17 lb

Therefore, The safe load, L of a wooden a beam 3 in. wide 9 in. deep and 11 ft long of the same material support is 307.17

Slope of a parallel line: 6

Slope of a perpendicular line: -1/6

What is Slope ?

slope, The inclination of a line with respect to the horizontal is measured numerically. The ratio of the vertical to the horizontal distance between any two points on a line, ray, or line segment is known as its slope in analytical geometry ("slope equals rise over run").

Given equation,

y=6x-4

The equation of a line with slope  m  is given as:

y=mx+c

Rearranging the given equation:

y=(6)x+(-4)

By equating the equations we get,

m= 6

Which is slope of a parallel line

Now any parallel line would have the same slope.

And slope of a perpendicular line would be  −1/m.

i.e.  m(perpendicular)= -1/6

Hence, Slope of a parallel line is 6 and Slope of a perpendicular line is -1/6

The value of x is the answer to the equation x - 2 = 16 which is 18.

An equation is an expression that shows the relationship between two or more numbers and variables. The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.

We have been given a linear equation as;  x - 2 = 16

We need to find the value of x as the answer to the equation x - 2 = 16.

Therefore, we will eliminate the 2.

x - 2 = 16

Add 2 on both sides of the equation;

x - 2 + 2= 16+ 2

Then ;

x = 18

Hence, the value of x is the answer to the equation x - 2 = 16 which is 18.

Answer:

C(x) = 75x + 1908

Step-by-step explanation:

C(x) is the cost function.

The cost of making x bicycles is the sum of the fixed costs and the cost per bicycle.

The fixed cost is $1908.

The cost per bicycle is $75, so the per bicycle cost for x bicycles is 75x.

Add the two costs, and you get:

C(x) = 75x + 1908

The given statement is false: vertical angle do not depend on the line being parallel. A pair of vertical angles are always congruent.

Vertical angle:

Vertical angle means that the angles opposite each other when two lines cross.

Given,

Here we have the diagram and we also know that angle 7 is congruent to angle 5.

Now we need to find the given statement is true or not.

Through the given diagram, we have identified that, the eight angles will together form four pairs of corresponding angles.

Angles 1 and 5 constitutes one of the pairs.

We know that all the corresponding angles are congruent.

All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6.

Through that we know that basically, the vertical angles are always congruent, which means that they are equal. So, it is not necessary for them to be parallel.

As per the concept of probability, there are 7776 different lottery numbers are possible.

Probability:

Probability means the concept that is based on the possible chances of something to happen.

Given,

Lottery numbers in a particular state consist of 5 digits. Each lottery cube that is drawn/rolled has six sides, numbered 1-6.

Here we need to find how many different lottery numbers are possible.

Through the given question we know that,

The number of digits in a lottery ticket = 5

Side in cube = 6

So, in each time they will roll the dice 5 times to get one number.

So, the possible options of that event are,

For the first time we have 6 options

Second time we got 6 options

Third time also we got six option

Fourth time = 6 options

Fifth time = 6 options.

Therefore, it can be written as,

=> 6 x 6 x 6 x 6 x 6

=> 6⁵

=> 7776.

4) Amount earned per hour = 4492.1875 * 60 = $269531.25

We are given;

Amount earned by athlete = $17,250,000

Number of games played = 80 Games

Number of minutes per game = 48 minutes

1) Amount earned per game = Amount earned by athlete/Number of games played = 17250000/80 = $215625 per game

What is Weight?

The weight of an object is the force exerted on it by gravity. Some standard textbooks define weight as a vector quantity, the force of gravity acting on an object. Some define weight as a scalar quantity that is the magnitude of gravity.

Cost of the different types of the apple have been given as,

Apple A = costing $4.90 for 4 lb

Apple B = costing $1.00 for 10 oz

Apple C = costing $0.45 for 1/2 lb

For Apple A,

Since, cost of 4 lb = $4.90

Therefore, cost of 1 lb = 4.90/4

                                    = $1.225

For Apple B,

Since, 1 oz = 0.0625 lb

Therefore, 10 oz = 0.0625 × 10

                            = 0.625 lb

Since, cost of 10 oz = $1.00          

Therefore, cost of 0.625 lb = $1.00

And cost of 1 lb = 1/0.625

                          = $1.6

For Apple C,

Since, cost of 1/2 lb = $0.45

Therefore, cost of 1 lb = 0.45 × 2

                                   = $0.90

 Hence, Cost of Apple A will be the least with $1.225 per pound.
