Answer:

128.57 degrees per each interior angle

Step-by-step explanation:

For interior angles of regular polygons, all you have to do is add 180 degrees to the sum for each side added. For example, from triangle to quadrilateral, you would do 180 + 180 to get 360. Then from quadrilateral to pentagon, you would do 360 + 180 = 540. Do that all the way up to a heptagon and you get a sum of 900 degrees. 900 divided by seven angles will get you 128.57 degrees per interior angle.

Answer:

each interior angle = 128.6°

Step-by-step explanation:

Sum of interior angles of  a polygon with n sides = ( n - 2) x 180°

Given n = 7

So, sum of interior angles = ( 7 - 2 ) x 180 = 900°

Given it is regular,

      therefore each interior angle :

                                             [tex]\frac{900}{7} = 128.6^\circ[/tex]

Answer:

If we multiply both the sides by 2, the inequality signs remains the same.

If we divide both sides by -2, the sign changes.

Step-by-step explanation:

The given inequality is

-8<2

If we multiply both the sides by 2, we get

-8 * 2 < 2*2

-16 < 4

The inequality signs remains the same.

On the other hand if we divide both sides by -2, we get -

-8/-2 < 2/-2

4 > -1

Here the sign changes.

Answer:

(x+1)² = 14

a = 1, b = 14

Step-by-step explanation:

Given the equation, x² + 2x = 13

We are to use the completing the square method to express in the form

(x + a)² = b

x² + 2x = 13

Add the square of half of the coefficient of x to both sides

Coefficient of x = 2

Half of the coefficient of x = 2/2

Square of the result = (2/2)²

Square of the result = 1²

Add (1/2)² to both sides

x² + 2x + (1)² = 13 + (1)²

(x+1)² = 13 + 1

(x+1)² = 14

Compare with  (x+a)² = b

a = 1 and b = 14

Answer:

Step-by-step explanation:

b(a + 1) + a = b*a + b + a = ab + b + a

1) b(2a +1 ) = b*2a + b*1 = 2ab + b  Not equivalent.

2)a + (a +1)*b = a + ab+ b     Equivalent

3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a  Not equivalent.

4) (a + 1)b + a = ab+ b + a   Equivalent

5) a + b(a+1) = a +ab + b Equivalent

6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b  Not equivalent.

7) a(b +1) + b = ab + a + b  Equivalent

Answer:

[tex]56.3[/tex]

Step-by-step explanation:

The Law of Sines works for any triangle and is given by [tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex] (the ratio of any angle and its opposite side is equal to the ratio of all other angles and their respective opposite sides).

Thus, we have:

[tex]\frac{\sin 28^{\circ}}{27}=\frac{\sin 102^{\circ}}{c},\\c=\frac{27\sin 102^{\circ}}{\sin 28^{\circ}}=56.2547070223\approx \boxed{56.3}[/tex]

Answer:

Wavelength = 16 m

Step-by-step explanation:

Given that,

In 6 seconds, a total of 3 waves crash into a cliff.

The distance between 2 adjacent wave crests on the water is 8 meters.

We need to find the wavelength of the wave.

We know that, the distance between two consecutive wave is called wavelength of a wave.

We can understand that, total of 3 wave crests, the distance between first and second wave crest is 8 meters.

Hence, the wavelength is 8 m + 8 m = 16 m

 72 different kinds of sandwiches can be made using 6 different types of bread, 4 different types of meat, and 3 different types of toppings

Given :

A sandwich shop offers 6 different types of bread, 4 different types of meat, and 3 different types of toppings

bread = 6 , meat=4, toppings=3

Sandwich is made of 1 type of bread, 1 type of meat, and 1 topping.

To find the number of combinations we multiply all the possible types we have

Number of combinations of sandwiches = [tex]6 \cdot 4 \cdot 3=72[/tex]

There are 72 different kinds of sandwiches.

The total loan payment is $1,024,050.

Another name for mortgage loans is "loans against property." A mortgage loan can be used to refinance real estate or to buy, build, or remodel a home. Getting a new loan for a piece of property while the old one is still being paid off is referred to as refinancing. Typically, it is done to obtain a loan with better terms.

We have,

The 30-year mortgage loan of $205,000 at 5.5% interest rate

We know, the total cost of this loan can be calculated as

L=LM+PMI

So, LM=$205,000 x (1+0.055[tex])^{30[/tex]

LM=$205,000 x 4.984

LM = $1,021,710

Now, the PMI over 24 months

= $97.5 x 24

= $2,340

So, the total loan payment is:

= $1,021,710 + $2,340

= $1,024,050

Answer:

x = 1, 2, 3, 4

Step-by-step explanation:

15x - 43 < 5x + 2

15x - 5x - 43 < 2

15x - 5x < 2 + 43

10x < 45

x < 4.5

x = 1, 2, 3, 4

The required value of the x in the given inequality is x < 4.5.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Given expression,
15x - 43 < 5x + 2

Adding 43 on both sides,
15x < 5x + 45

Subtract 5x from both sides,
10x < 45

Divide the inequality by 10
x < 4.5

Thus, the required value of the x in the given inequality is x < 4.5.

Answer:

y = 3x - 8

Step-by-step explanation:

Finding the equation in point-slope form is easier.  The result can then be put into slope-intercept form.

The point-slope formula is y - k = m(x - h).  With the given point (h, k) being (4, 4), h = 4 and k = 4.  The slope is 3.  Therefore, we have:

y - 4 = 3(x - 4), or

y = 4 + 3x - 12

This simplifies to the slope-intercept form y = 3x - 8

Answer: 0.033 liters or 33 ml each

Step-by-step explanation:

There are 33 liters of orange juice and 1,010 students to drink it.

If they are to drink an equal amount, you should divide the quantity of orange juice by the number of students who want to drink it:

= Quantity of orange juice / Number of students drinking

= 33 / 1,010

= 0.033 liters each

In milliliters this would be:

= 0.033 * 1,000 milliliters

= 33 ml each

Answer:

The sum of money deposited is approximately $22,021.74

Step-by-step explanation:

The given interest and amounts of the deposit are outlined as follows;

The simple interest per annum, R = 0.325%

The number of years the money is deposited, T = 4 years

The total amount received (Interest + Initial deposit), A = $50,650

We have;

I = P × R × T

Where;

P = The principal (initial amount deposited)

R = The (annual) interest rate = 0.325%

T = The time = 4 years

Therefore;

The total amount received, A = P + I

P + I = P + P × R × T = P × (1 + R × T)

∴ A = P + I = P × (1 + R × T)

P = A/(1 + R × T)

Plugging in the values, gives;

P = 50,650/(1 + 0.325 × 4) = 506,500/23 ≈ 22,021.74

The sum of money deposited, P = $22,021.74

Answer: what’s the link about ?

From the figure, We can notice that Sum of the angles (∠AKC and ∠AKE) should be equal to 180°

Because ∠AKC and ∠AKE make a Linear Pair

⇒  ∠AKC + ∠AKE = 180°

⇒  5x + 12x + 27 = 180

⇒  17x = 180 - 27

⇒  17x = 153

⇒  x = 9°

⇒  ∠AKE = 12(9) + 27 = (108 + 27) = 135°

Answer : ∠AKE = 135°

Answer:

x = 20

Step-by-step explanation:

The diagonals of a kite are perpendicular to each other, so the 4 angles at the  intersection are right.

The sum of the 3 angles in a triangle sum to 180° , then

2x + 2x + 10 + 90 = 180

4x + 100 = 180 ( subtract 100 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20
