No, Her goal was to earn $300 but she managed to earn only $270, selling calendars.

Any system that divides time into discrete units, such as days, months, or years, and places those units in a specific order is known as a calendar. A calendar is useful for keeping track of historical events, religious holidays, and other observances, as well as for scientific and historical research.

The word is derived from calendae (or kalendae), the first day of the month in the Roman republican calendar, the day on which future market days, feasts, and other occasions were announced. Calendae is the Latin word for "interest register" or "account book," which is itself a derivation from calendae.

Given that:

Cost of each calendar = $9

Number of calendar sold to the family = 16

Number of calendar sold to the neighbourhood = 14

So, The total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighbourhood

Total number of calendar sold by Celia = 16 + 14 = 30

The cost of each calendar = $ 9

The cost of 30 calendar = $ 9 × 30 = $ 270

Therefore, she could not reach her goal as her goal was to earn $300 but she managed to earn only $270.

The length of given point is 1 units. The total length of the actual path followed by an object is called as distance.

Use the formula d = st, or distance equals speed times time, to find the distance. Since both represent a certain amount of distance per unit of time, such as miles per hour or kilometres per hour, rate and speed are comparable. If speed s and rate r are equal, then r = s = d/t.

On solving the provided question, we can say that if the length of GF IS 8 unit then  the length of HI(Diameter) = 16 unit.

The diameter of a circle cuts through the center whereas the radius extends from the center to the edges of the circle. The diameter of a circle effectively divides the shape in two.

A chord is a straight line that is drawn between two points on a circle when it is used in mathematics (or more generally, on any curve). A table of chords was the first trigonometric table ever discovered. Nowadays, the sine is employed in its place (sines and chords are connected), but chords might be more understandable to some people.

Radius is "GF"

Therefore ,the solution of the given problem of triangle comes out to be

area is 84 inch square.

Since a triangle has number of sides and three vertices, it is a polygon. It is a fundamental geometric shape. Triangle ABC is the moniker assigned to a triangle that has edges A, B, and C. So when three components are not collinear, a singular plane and triangle are found in Euclidean geometry. A triangle is a polygon if it has three sides and triple corners. The points where the three parts meet are known as the triangle's corners. The product of three triangle angles is 180 degrees.

Here,

Given : 7 inch , 25 inch and 24 inch.

To find the area of the triangle :

The width of the flower bed is 3m.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Rectangular lawn = 8m x 4m

The flower bed dimensions are:

Length = (8m + x)

Width = x

The combined area of lawn and flower bed area = 140 m²

(8 + 2x) x (4 + 2x) = 140

32 + 16x + 8x + 4x² = 140

Answer:

a = 99

b = 51

Step-by-step explanation:

We can translate this problem into a linear equation. We know that:

2b - 3 = a

and

a + b = 150

We will start by minusing b from both sides in the second equation, giving us:

a = 150 - b

Then, we will substitute this into our second equation, giving us:

2b - 3 = 150 - b

We will add 3 and b to both sides, giving us:

3b = 153

Then we divide by 3:

b = 51

Now, we will substitute this into our second equation, giving us:

a + 51 = 150

Subtract 51 from both sides gives us:

a = 99

So, the a piece is 99 yards long, and the b piece is 51 yards long.

a = 99

b = 51

Answer:

m = 2 K.E / v^2

Step-by-step explanation:

K.E = 1/2 mv^2

K.E × 2/1 = mv^2

2 K.E = mv^2

2 K.E × 1/ v^2 = m

∴ m = 2 K.E / v^2

[tex]m=\frac{2KE}{v^{2}}[/tex].

Just for general knowledge. This is a formula from physics, specifically, classical mechanics. It is used to calculate the kinetic energy of bodies, that what the varaible "KE" stands for.

Now, let's rearrange the formula!

[tex]KE=\frac{1}{2} mv^{2}[/tex]

[tex]2KE=\frac{1}{2} mv^{2}*2\\ \\2KE=mv^{2}[/tex]

See that the 2 is used to cancel the 1/2 fraction.

[tex]\frac{2KE}{v^{2}} =\frac{mv^{2}}{v^{2} } \\ \\\frac{2KE}{v^{2}} =m\\ \\m=\frac{2KE}{v^{2}}[/tex]

[tex]m=\frac{2KE}{v^{2}}[/tex].

If the result is correct, then the equation should return the same value of both sides of the equal symbol (=) when we substitute the variable "m" by it's calculated value, [tex]\frac{2KE}{v^{2}}[/tex].

[tex]KE=\frac{1}{2} (\frac{2KE}{v^{2}})v^{2}[/tex]

Here, the 1/2 fraction is cancelled by the 2 inside the parenthesis. Also, the v² is cancelled out by the v² that's dividing inside the parenthesis, leaving us with this expression (check attached image to better understand this step):

[tex]KE=KE[/tex]

As you can tell, the same variable appears on both sides of the equal symbol, this means that the result is correct!

A polygon will map to itself after a rotation of a 60° would be a regular hexagon.

What is a polygon?

A polygon is a closed, two-dimensional geometric shape that is defined by a set of straight lines, called its sides, that are connected end-to-end. The number of sides in a polygon is referred to as its "order" or "degree"

A polygon that maps to itself after a rotation of 60 degrees is called a regular hexagon. A regular hexagon is a polygon with six sides of equal length and six angles of equal measure (120 degrees each).

To sketch a regular hexagon, you can start by drawing a dot in the middle of a piece of paper. From there, use a compass or a straightedge to draw a circle around the dot. Then, use the compass to draw six lines from the center of the circle to the edge of the circle, each line being 60 degrees apart from the other. Finally, connect the endpoints of each line to form a six-sided polygon.

Hence, a polygon will map to itself after a rotation of a 60° would be a regular hexagon.

Use the nth term formula for AP:

Answer:

a)  Arithmetic sequence

b)  t(n) = 16 - 3n

Step-by-step explanation:

An Arithmetic Sequence has a constant difference between each consecutive term.

A Geometric Sequence has a constant ratio (multiplier) between each consecutive term.

From inspection of the given table, t(n) decreases by 3 each time n increases by 1.  Therefore, the sequence is arithmetic with a common difference of -3.

Given:

Substitute the initial value (when n = 1) and the common difference into the formula to create an equation for the nth term:

The area of a triangle can be solved for using the formula:

[tex]A_\triangle = \dfrac{1}{2}b h[/tex]

where [tex]b[/tex] is the length of the triangle's base and [tex]h[/tex] is the length of its height (altitude).

Both [tex]b[/tex] and [tex]h[/tex] are given to us for the shown triangle, so all we have to do is plug the given values into the triangle area formula above.

[tex]A = \dfrac{1}{2} \cdot 10 \cdot 25[/tex]

[tex]A = 5 \cdot 25[/tex]

[tex]A = 125 \textrm{ yd}^2[/tex]

Note that the height of the triangle is given on the outline of an auxiliary (dotted) right triangle. This is just to show that the height is in fact an altitude, meaning it is perpendicular to the base, not at the angle of the triangle's other sides.

The measure of the tan of the angle T is 3.4286

From the question, we have the following parameters that can be used in our computation:

Opposite = RS

Hypotenuse = 50

Adjacent = 14

The opposite of the angle T can be calculated as

Hypotenuse² = Opposite² + Adjacent²

Substitute the known values in the above equation, so, we have the following representation

50² = RS² + 14²

Evaluate the like terms

RS² = 2304

Take the square root of both sides

RS² = 48

The measure of the tan of the angle T is then calculated as

tan(T) = RS/Adjacent

Substitute the known values in the above equation, so, we have the following representation

tan(T) = 48/14

Evaluate

tan(T) = 3.4286

Hence, the value is 3.4286
