Kevin claims that the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself is 156° since 180(15−2)15=156. Decide if Kevin is correct. If Kevin is correct, enter 156 below. If Kevin is incorrect, enter the correct value of the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself.

Answers

Answer 1

Answer:

Step-by-step explanation:

The formula for calculating the interior angle of a polygon is expressed as;

sum of internal angle = (n-2)180 where;

n is the number of sides of the polygon in consideration.

Given a 15 sided polygon, n = 15

sum of internal angle = (15-2)180

sum of internal angle = (13)180

sum of internal angle = 2340

Hence kevin is wrong, the correct answer is 2340

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (12, 5); m = -3

Answers

Answer:

y - 5 = -3(x - 12)

Step-by-step explanation:

Point slope form is: y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.

Plug in the point and the slope:

y - y1 = m(x - x1)

y - 5 = -3(x - 12)

So, y - 5 = -3(x - 12) is the equation in point slope form of the line.

The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.

Given that the sum of 3 consecutive integers is 48.

We need to find the smallest of the integers.

Let assume the 3 consecutive integers are x, (x+1) and (x+2)

Therefore, x+(x+1)+(x+2)= 48

The total balance of Greg account after he makes the monthly payment for July is $864.99.

How to find monthly payment?

Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.

It can be calculated with the following formula.

[tex]M=P\left(1-\dfrac{r}{1-(1+r)^{-nt}}\right)[/tex]

Here, (P) is the principal amount, (r) is the interest rate and (t) is time.

Greg has a credit card which requires a minimum monthly payment of 2.06% of the total balance.

His card has an apr of 11.45%, compounded monthly. At the beginning of May, Greg had a balance of $318.97 on his credit card.

In the Month of May he make payment of 46.96, 33.51, and 26.99. Greg had a balance of $318.97 on his credit card. The total balance after the end of may is,

[tex]P=46.96+33.51+26.99+318.97\\P=426.43[/tex]

The financial charge on this payment with Apr 11.45% is 4.07. Thus, the payment become 430.5.

The payment for the June 97.24, 112.57,72.45. The payment at the end of June is 719.56 and financial charge is 10.22.

The payment become 722.98. The payment for the June 41.14, 101.84. At the end of July 865.96.

The total balance of Greg account after he makes the monthly payment for July is $864.99.

By coincidence, they played the same number of games for the same total cost. How much did each one spend? How many games did each one play?

Answers

Answer:

Each one of them spent $38

Each one of them played 6 games.

Step-by-step explanation:

The number of games be represented by g

Colette went to play miniature golf on Monday, when it cost $14 to rent the club and ball, plus $4 per game.

$14 + $4 × g

= 14 + 4g

Maddie went Thursday, paying $6 per game, plus rental fees of $2.

$2 + $6 × g

= 2 + 6g

The equation is :

14 + 4g = 2 + 6g

We solve for g

Collect like terms

14 - 2 = 6g - 4g

12 = 2g

g = 12/2

g = 6

How many games did each one play?

Each one of them played 6 games.

How much did each one spend?

For Colette

The amount she spent :

14 + 4g

=$14 + 4 × 6

= $14 + 24

= $38

For Maddie

EJERCICIOS: Resuelvan los problemas aplicando regla de tres en conversion de metros a varas A) Una mesa cuadrada mide 1.85 M de lado ¿ cuantas varas debe tener cada tabla de largo para fabricarla? B) Jose tiene un lote de 25 M de largo y 15 M de ancho ¿cuantas varas cuadradas tiene el terreno? Por favor ayuda es para ahorita si mo saben no contesten ok por favor gracias

Answers

Answer:

A) Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) El lote de José tiene una extensión de 536.481 varas cuadradas.  

Step-by-step explanation:

A) La vara es una unidad de longitud equivalente a 0.836 metros. También sabemos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos rectos, de modo que la longitud y ancho de la mesa es igual. Entonces, el largo de la tabla, esto es, la superficie superior de la mesa, tiene una medida de 1.85 metros.

A continuación, realizamos la regla de tres para determinar su equivalente en varas:

[tex]x = 1.85\,m\times\frac{1\,vara}{0.836\,m}[/tex]

[tex]x = 2.213\,varas[/tex]

Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) La vara es una unidad de longitud equivalente a 0.836 metros. Una vara cuadrada es una unidad de área y es igual a:

[tex]r = (0.836\,m)\cdot (0.836\,m)[/tex]

[tex]r = 0.699\,m^{2}[/tex]

De manera semejante, tenemos que el área del lote de Jose es un rectángulo y que se calcula como sigue en metros cuadrados:

[tex]A = l\cdot w[/tex] (Eq. 1)

Donde:

[tex]A[/tex] - Área del lote de José, medido en metros cuadrados.

[tex]l[/tex] - Largo del lote de José, medido en metros cuadrados.

[tex]w[/tex] - Ancho del lote de José, medido en metros cuadrados.

Si [tex]l = 25\,m[/tex] y [tex]w = 15\,m[/tex], entonces el área del lote es:

[tex]A = (25\,m)\cdot (15\,m)[/tex]

[tex]A = 375\,m^{2}[/tex]

Por último, hallamos el área en varas cuadradas mediante la siguiente regla de tres:

[tex]x = 375\,m^{2}\times \frac{1\,vara}{0.699\,m^{2}}[/tex]

[tex]x = 536.481\,varas^{2}[/tex]

El lote de José tiene una extensión de 536.481 varas cuadradas.

The Highest Common Factor of 264627 and 305613 is 891.

What is Highest Common Factor?

The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one.

For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.

Given:

264627 and 305613

Now, prime factorizing both number

264627  = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 11 x 11

and, 305613 = 3 x 3 x 3 x 3 x 7 x 7 x 7 x 11

c.the slope is 1/3 and the y intercept is -2/5

d.the slope is 2/5 and the y intercept is -1/3​

Answers

Answer:   a. the slope is -2/5 and the y-intercept is -1/3

Step-by-step explanation:

Find the slope by finding the difference in x-values divided by the difference in y-values

(1/4 ,-13/30) and (-3/4, -1/30)  are useful values

-13/30 --1/30 = -12/30    = -2/5 is the rise      

-1/4 - -3/4 = 1  is the run (-2/5)/1 Division by 1 leaves the original numerator)

the slope is -2/5

To find the y intrcept, substitute the y and x values from any given coordinate into the slope intercept form and solve for  b

y= mx + b

-3/5 = (-2/5)(2/3) + b

-9/15 + 4/15 = b

-5/15 = b

-1/3 = b  This is the y-intercept

26.22 foot

Step-by-step explanation:

The relation between foot and meter is given by :

1 foot = 0.305 meter

We firstly find value of 1 meter in terms of foot.

So,

[tex]1\ m=\dfrac{1}{0.305 }\ \text{foot}[/tex]

To find no of foot in 8 meters, multiply [tex]\dfrac{1}{0.305 }[/tex] by 8 i.e.

How many solutions and what type of solutions does a quadratic equation have if the value of the discriminant is a positive perfect
square?

2 rational solutions

2 irrational solutions

1 rational solution

O real solutions

Answers

Answer:

2 rational solutions

Step-by-step explanation:

the degree of the polynomial (the highest exponent of the variable) defines how many solutions there are.

that means for how many values of x the result y is 0 (how many x-axis interceptions there are or should be).

so, a quadratic equation has 2 such solutions.

there are a few different cases how these solutions present themselves :

"normal case" : all the solutions are real (not only rational) numbers, and the curve has that many different x- acid interceptions.

a turn of the curve leads to only "touching" the x-axis : this is just a special case that the curve is "too high" or "too low" and the regular 2 intersects merge into 1. there are formally still 2 solutions, but they are identical.

there can be "S-curves" especially for higher degrees (3 and up) with the center smoothing in with the x-axis : this is similar but can merge even more than 2 solutions into 1.

the curve is really "too high" or "too low" and never even touches the x-axis : then the solutions are irrational.

the general solution for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

the discriminate is (b² - 4ac).

if this is a positive perfect square, then the square root is a perfect integer. in fact, 2 perfect integers (+ and -).

and so we get two solutions with integer/integer and they are therefore 2 rational solutions.
