Anyone know what the answer to this is?

A force of 85 N is applied over an area of 530 cm2. Then the pressure on it is equal to 1603.8 [tex]\frac{N}{m^{2} }[/tex].

Force(F) = 85 N

Area(A) = 530 [tex]cm^{2}[/tex]

Pressure(P) = ?

Calculating as per the above amount

Area = 530/100 × 100

= 0.053 [tex]m^{2}[/tex]

The definition of pressure is "force applied per unit area." The equation P = FA, where F is the force acting perpendicular to surface area A, provides the answer. The pascal (Pa), or one newton per square meter, is the accepted unit of pressure [tex]\frac{N}{m^{2} }[/tex].

Pressure is the physical amount of force exerted on a particular area. The definition of pressure is "force per unit of area." The pressure being applied to a body can be calculated by taking the amount of force being applied and dividing it by the area of contact.

Pressure = force/area

= 85/0.053

= 1603.8 [tex]\frac{N}{m^{2} }[/tex]

Pressure on the body is 1603.8 [tex]\frac{N}{m^{2} }[/tex]

The equation to represent the cost of each drink is 3(x + 2.5) + 3x = 25.50. The cost of each drink will be $3.

In the given question, it is stated that the family spent a total of $25.50 and they bought 3 Popcorn and 3 Drinks. Each popcorn costs $2.5 more than the drink. Now, suppose the cost of one drink is 'x' then we get:

Cost of 3 Drinks = 3x

Cost of 3 Popcorn = 3(x + 2.5)

The equation to represent this will be:

=>  3(x + 2.5) + 3x = 25.50

=>  3x + 7.5 + 3x = 25.50

=>  6x = 18

=>  x = 3

We get x = 3, Cost of one drink will be $3

Hence,  equation representing it will be 3(x + 2.5) + 3x = 25.50, and the cost of each drink will be $3

2. The graph of the line with a slope of 4/3 is shown in the image below.

Slope of a line = change in y / change in x = rise/run.

The equation that can be used to represent a linear graph can be written in slope-intercept form as y = mx + b, where the value of b is the y-intercept of the line and the value of m is the slope of the line.

1. Using two points on the line, (0, -1) and (1, 5):

Slope of the line = change in y / change in x = (-1 - 5)/(0 - 1)

Slope of the line = -6/-1

Slope of the line = 6

2. Slope (m) = 4/3

A point on the line is given as (1, 3)

Write the equation of the line by substituting (a, b) = (1, 3) and m = 4/3 into y - b = m(x - a):

y - 3 = 4/3(x - 1)

y - 3 = 4/3x - 4/3

The arity typically assumed to be limited. The "typical" operations of finite dimensionality are referred to as the finiteary operations when infinitary operations are taken into consideration. The mean of the five numbers is 8.2, four of numbers are 8, 10, 12 and 10. The fifth number is 1.025.

An operation, often known as a "operand" or "argument," is the function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.

Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of operation of arity 3, sometimes known as a ternary operation, is the mixed product.

a) Because it is an equilateral triangle, all the sides must have equal lengths.

The perimeter = 24cm -> Each side = 8.
Area = 1/2 b.h = 8.8.1/2 = 32 cm2.

b) A square has all of its sides of equal lengths just like an equilateral triangle.

The perimeter = 24cm -> Each side = 6.
Area = side.side = 6.6 = 36 cm2.

c) Since they have equal perimeters and the same properties (all sides equal) BUT they have different number of sides and lengths, they won't have the same areas.

d) A rectangle. E.g :
A set of lengths of 5cm and 7cm makes a rectangle with a perimeter of 24cm : (5+7).2

But, its area equals 5 x 7 = 35cm2, which is greater than the triangle.

Answer:

a) 27.71 cm²

b) 36 cm²

Step-by-step explanation:

a) Perimeter of equilateral triangle = 3a

Here, a is the side of equilateral triangle.

Perimeter of equilateral triangle = 24 cm

                   3a = 24 cm

                    a = 24 ÷ 3

                    a = 8 cm

[tex]\sf Area \ of \ equilateral \ traingle = \dfrac{\sqrt{3}}{4}a^2[/tex]

                                         [tex]\sf = \dfrac{\sqrt{3}}{4}*8*8\\\\ = 1.732*2*8\\\\ = 27.71 \ cm^2[/tex]

b)   Perimeter of square = 4s

Here, s is the side of square.

Perimeter of square = 24 cm

                         4s = 24

                           s = 24 ÷ 4

                           s = 6 cm

Area of square = s*s

                         = 6 * 6

                         = 36 cm²

c)  When the dimensions (length, width, height) of the shape changes, the area and volume changes.

d) Length of the rectangle is 10 cm and width is 2 cm.

Perimeter of rectangle = 2*length + 2* width

                                      = 2*10 + 2*2

                                       = 20 + 4

                                       = 24 cm

Area of perimeter of rectangle = length *width

                                                   = 10 * 2

                                                   = 20 cm²

Interior angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles

The method that can not be used to prove that lines i and k are parallel is the statement "shows that both lines are perpendicular to a third line".

Lines l and k intersect forming two pairs of vertical angles. If one of these angles measures 120°,

As per the given question,

Let angle ∠1 is 120°

here angles ∠1 and ∠2 are supplementary

So  ∠2 = 180° - 120° = 60°

However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

∠2 = ∠4 = 60°

∠1 = ∠3 = 120°

Therefore, the measures of the other three angles are 60°, 60°, and 120°.

Note that just like solving a linear equation, instead of having two sides, you have three. And, whatever you carry out on one side, you have to carry out on all three.

Although, unlike linear equations, if you are dividing/multiplying all sides with a negative integer, then you have to flip the signs.

9^(2-x) = 3 -> 2-x = 1/2

into details about why it is 1/2 (ill call 2-x as y for easier demonstration)

9^y = 3
(3^2)^y = 3

And we have : (x^m)^n = x^mn
-> (3^2)^y = 3^2y = 3
-> 2y = 1
y = 1/2, therefore 2-x = 1/2.

So, x = 2 - 1/2 = 3/2.

the values of both angles are

2x - 8 = 2*25 - 8

          = 42 degree

x -7 = 25 - 7

      = 18 degree

Both internal and external angles make up a triangle. The angle that forms between two of a triangle's adjacent sides is known as the interior angle. The angle created between a triangle's side and its next-to-furthest side extending outward is known as the exterior angle. Triangle Angle sum feature of triangle states for ABC that 180 degrees is the sum of the triangle's internal angles.

2x - 8 + x - 7 + 90 = 180

3x - 15 = 90

x = 25

therefore the values of both angles are

2x - 8 = 2*25 - 8

          = 42 degree

x -7 = 25 - 7
