Is 5/8 a reciprocals

Answer:

If area of sector = area of circle

1/3π(r+4)^2= πr^2

r^2-4r-8 =0

A sector is a cut out section of a circle. It is of two radii and an arc .

The area of a sector is angle substended/ 360 x area of a circle

area of a circle is πr^2

if area of circle is equal to the area of sector

120/360×π(r+4)^2=πr^2

divide both side by π

1/3(r+4)^2=r^2

multiply both sides by 3

(r+4)^2=3r^2

opening the bracket

(r+4)(r+4)=3r^2

r^2+ 8r +16=3r^2

3r^2-r^2- 8r -16=0

2r^2- 8r -16=0

divide all by 2

r^2- 4r -8=0

Answer:

1100

Step-by-step explanation:

783 rounded to the nearest hundred is 800

329 rounded to the nearest hundred is 300

800+300=1100

The estimation of 783 + 329 = 1100.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.

Given:

783 + 329

Now rounding off nearest hundred

783 rounded off to 800

and, 329 rounded off to 300.

So, 800+ 300 = 1100

Hence, the estimation is 1100.

Answer:

y = [tex]\frac{1}{4}[/tex] x - 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given m = [tex]\frac{1}{4}[/tex] , then

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

to find c substitute (- 8, - 8 ) into the partial equation

- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6

y = [tex]\frac{1}{4}[/tex] x - 6 ← equation of line

Time is continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience. Time is often referred to as fourth dimension, along with three spatial dimensions.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and performing arts all incorporate some notion of time into their respective measuring systems.

The smallest drawing will be the one that has the smallest drawing unit with respect to the the actual unit.

We have:

A. 1 in to 1 ft

B. 1 in to 1 m

C. 1 in to 1 yd

If we put them all in meters, we have:

A. 1 in to 0.3048 m

B. 1 in to 1 m

C. 1 in to 1/1.1 = 0.90... meters

Then, the small drawing will be B, as 1 meter is the largest actual unit.

Second, will be B, that has 1 in by approximately 0.9 meters.

Third and last, option A, which drawing has an scale of 1 in in 0.3048 meters.

We can calculate the scale as a ratio between the drawing units and actual units, expressed in the same units.

For example, for A, we have:

So the scale is 1:12.

NOTE: look that we have cancelled all the units with this operation.

For B, we have:

For C, we have:

You can verify that B has the smallest scale (0.0254)

Step-by-step explanation:math

The $7,834.54 borrowed at 18.6% annual interest rate with the landscape architect's monthly payment of $500, gives the number of months it will take to repay the debt as approximately 19 months

Monthly payment on a loan, is the amount the person who takes the loan, pays each month in order to settle the loan in a given time period.

The monthly payment formula is presented as follows;

[tex] \displaystyle{M = \frac{P \cdot \left( \frac{r}{12} \right) \cdot \left( 1 + \frac{r}{12} \right)^{n} }{\left( 1 + \frac{r}{12} \right)^{n} - 1} }[/tex]

Where;

M = The amount the landscape architect paid monthly = $500

P = The amount loaned or borrowed = $7,834.54

r = The interest per annum = 18.6%

n = The number of monthly payment made

Therefore;

[tex] \displaystyle{500 = \frac{7834.54 \cdot \left( \frac{0.186}{12} \right) \cdot \left( 1 + \frac{0.186}{12} \right)^{n} }{\left( 1 + \frac{0.186}{12} \right)^{n} - 1} }[/tex]

Evaluating the above equation gives;

[tex] \displaystyle{500 = \frac{121.43537.1 \cdot 1.0155^{n} }{1.0155^{n} - 1} }[/tex]

[tex] \displaystyle{500 \times (1.0155^{n} - 1) = 121.43537.1 \cdot 1.0155^{n} }[/tex]

[tex] \displaystyle{500 \times 1.0155^{n} - 121.43537.1 \cdot 1.0155^{n} ) = 500 }[/tex]

Which by taking natural logarithms of both sides gives;

n•ln(1.0155) = ln(1.32077843609)

n = ln(1.32077843609) ÷ ln(1.0155) ≈ 18.09

Rounding up to the nearest month gives;

The number of months it will take the architect to pay the debt is approximately 19 months

Matching the trigonometry formula to its ratio, we get

4/5 → sin A

3/5 → cos A

From the question, we are to match the given trigonometry formulas to their correct ratios.

From SOH CAH TOA, we have that

sin (angle) = opposite / hypotenuse

cos (angle) = adjacent / hypotenuse

tan (angle) = opposite / adjacent

Considering angle A,

Opposite = 16

Adjacent = 12

Hypotenuse = 20

Thus,

tan A = 16 / 12 = 4 / 3

sin A = 16 / 20 = 4 / 5

The equation of the line that passes through the graph is y + 2 = -3/2(x - 2)

The graph represents the given parameter

From the graph, the points are given as

(0, 1) and (2, -2)

Calculate the slope of the points using

Slope = (y₂ - y₁)/(x₂ - x₁)

Rewrite as

m = (y₂ - y₁)/(x₂ - x₁)

This means that

Slope = m

So, we have the following representation

m = (-2 - 1)/(2 - 0)

Evaluate

m = -3/2

The equation of the line is then calculated as

y = m(x - x₁) + y₁

Where

(x₁, y₁) = (2, -2)

m = -3/2

So, we have

y = -3/2(x - 2) - 2

Add 2 to both sides

y + 2 = -3/2(x - 2)

Hence, the equation of the line is y + 2 = -3/2(x - 2)
