Final answer:
To find the weight W such that the support force at A is zero, the principle of static equilibrium is used. By taking moments about point B and setting the sum of moments to zero, W is found to be 342.5 N.
Explanation:
The question requires the application of the principles of static equilibrium to find the unknown weight W that would set the supporting force at point A to zero. In static equilibrium, the sum of all forces and the sum of all torques (moments) about any point must be zero.
We can analyze the forces acting on the beam by taking moments about point B to find the value of W. Because the support at A is required to exert no force, we only consider the gravitational force due to the beam's weight and the weight applied at point B. By setting the sum of moments about B to zero, we can solve for W.
Using the conditions for static equilibrium:
Sum of vertical forces = 0
Sum of moments (torques) = 0
The moment leverage for the 685 N weight is at L/4, and for the unknown weight W, it is at L/2. Assuming the beam is massless the equation for the sum of moments around point B is:
(685 N) * (L/4) - (W) * (L/2) = 0
Solving for W:
W = (685 N) / 2
Thus, W is equal to 342.5 N.

What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
given that,
A Family spends 240.00 per week on food. If this is 16% of their income.
let,
x = weekly income (in dollars)
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500
Hence, The family's weekly income is $1500.

Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.
We know when we have the same radical we can simply multiply the values.
Given, [tex]\sqrt[3]{24}\times\sqrt[3]{45}[/tex].

Use the intercepts to graph the equation 8x - 5y = 40
To graph the equation 8x - 5y = 40, find the x-intercept and y-intercept. The x-intercept is (5,0) and the y-intercept is (0,-8). Plot these points and draw a straight line passing through them.
Explanation:To graph the equation 8x - 5y = 40 using intercepts, we need to find the x-intercept and y-intercept. The x-intercept is the point where the line intersects the x-axis, so let y = 0 and solve for x. The y-intercept is the point where the line intersects the y-axis, so let x = 0 and solve for y.
Setting y = 0, we get 8x - 5(0) = 40, which simplifies to 8x = 40. Solving for x, we find x = 5. So the x-intercept is (5, 0).
Setting x = 0, we get 8(0) - 5y = 40, which simplifies to -5y = 40. Solving for y, we find y = -8. So the y-intercept is (0, -8).
Plotting the x-intercept (5, 0) and the y-intercept (0, -8) on a graph, we can draw a straight line passing through these two points, which is the graph of the equation 8x - 5y = 40.

Mary and Jerry's number will be 39 and 50.The sum of their numbers is 89.Which shows that the obtained answer is correct.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let, Mary’s number be x
Mary’s number is eleven more than Jerry’s
Jerry's number is x+11
From the given condition sum of their numbers is 89.
[tex]x + (x + 11) = 89\\\\ 2x + 11 = 89\\\\ 2x = 89 - 11\\\\ 2x = 78\\\\ \frac{2x}{2} = \frac{78}{2} \\\\ x = 39[/tex]
Jerry's number will be;
[tex]x+11 \\\\ 39+11 \\\\ 50[/tex]
Hence the Mary and Jerry's number will be 39 and 50.

HELP PLEASE! −3.64⋅|−5.3|−1.53 what is the anwser?
The expression simplifies to approximately -20.822. It involves multiplying -3.64 by the absolute value of -5.3 and then subtracting 1.53 from the result.
To calculate this expression, follow the order of operations (PEMDAS),
which stands for Parentheses, Exponents, Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).
In expression, there are no parentheses or exponents, so we proceed with multiplication and then subtraction:
-3.64 × |-5.3| - 1.53
Calculate the absolute value of -5.3, which is 5.3.
Multiply -3.64 by 5.3.
Finally, subtract 1.53 from the result.
-3.64 × 5.3 - 1.53
Now, do the multiplication:
-19.292 - 1.53
Now, subtract:
-19.292 - 1.53 = -20.822

Different types of parallelograms have distinguishing traits. Compare and contrast the rectangle, rhombus, and square based upon the characteristics of their angles. Which one(s) have angles whose sum is 360 degrees? Which one(s) have both pairs of opposite angles that are congruent? Which one(s) have four angles?
The square, rectangle, and rhombus are all considered parallelograms. Squares have four sides, four 90 degree angles, 2 pairs of opposite congruent angles (all the angles are congruent), the angles add up to a sum of 360 degrees. Rectangles have four sides, four 90 degree angles that add up to 360 degrees, 2 pairs of opposite congruent angles (all the angles are congruent). Rhombuses have four sides, four angles in total measuring up to 360 degrees no matter the combination of angles because the oposite angles are congruent (2 acute angles and two obtuse angles).
While the rhombus is the only shape within this trio to have a pair of congruent acute and a pair of congruent obtuse angles the square and rectangle both have 4 congruent angles. All 3 shapes have a sum of 360 degrees when the angles are added together, all 3 have pairs of opposite angles being congruent, and all 3 shapes have 4 angles in total.

The price of a ticket was increase from 50p to 60p. What is the increase a as a fraction in its simple form? As a percentage of the original price?
Given is the price increase of a ticket from 50p to 60p.
Using the concept of fractions, we can find the ratio of new price to old price as follows :-
[tex] \frac{new \;\; price}{old \;\; price} = \frac{60p}{50p} =\frac{6}{5} [/tex]
So the increase in price is [tex] \frac{6}{5} [/tex] times old price of the ticket.
Using the formula of percentage, we can find the percentage change in price as follows :-
[tex] Percentage = \frac{(new\;\;price \;-\; old\;\;price) }{old \;\; price}*100 \\\\
Percentage = \frac{60p-50p}{50p}*100 \\\\
Percentage = \frac{10p}{50p}*100 \\\\
Percentage = 20\;\% [/tex]
Hence, Percentage increase is 20% of the original price.
