Answer:

A = 660.72 in^2 - A = 98 in^2 = 562.7 in^2

Step-by-step explanation:

Formula for a seven sided polygon/heptagon is:

A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n

n n = 7 sides

side length a = 13.4841 in

inradius r = 14 in

circumradius R = 15.5388 in

area A = 660.72 in^2

perimeter P = 94.3886 in

interior angle x = 128.571 °

exterior angle y = 51.4286 °

To calculate the square from a diameter use this formula: q = √(2a^2) = a√2

side length a = 9.8994949366117 in

diagonal q = 14 in

perimeter P = 39.597979746447 in

area A = 98 in^2

Answer:

m<A = 30degrees

m<B = 70degrees

Step-by-step explanation:

Find the diagram attached

From the diagram;

m<A + 150 = 180

m<A = 180 - 150

m<A = 30degrees

Also since the sum of angles in a triangle is 180degrees, hence;

m<B+m<A + 80 = 180

m<B+30+80 = 180

m<B+110 = 180

m<B = 180 - 110

m<B = 70degrees

The length of the piece of ribbon = 3 1/2 yards= 7/2 yards

The length of ribbon required to make  a bow =  3/4 yards

Now, the number of bows can be made in the given piece of ribbon = 7/2 divided by 3/4

 = 7/2*4/3= 14/3 = 4 2/3

Hence,  the number of bows can be made in the given piece of ribbon =  4 2/3

Answer:

76

Step-by-step explanation:

Put the numbers in order from least to greatest.

72, 73, 75, 76, 76, 79, 83, 86

Then, cross off each number at each end until you reach the one in the middle. Which, since they are the same, is 76.

Answer:

the answer is 4

Step-by-step explanation:

Answer:

The answer is G. The sum of r and 4 minus t

Step-by-step explanation:

It is G because an expression has no equal sign or answer, an equation has an answer.

Answer:

f(x) = 12*(2)^x

Step-by-step explanation:

A generic exponential equation is written as:

f(x) = A*(r)^x

And we also know that this equation passes through:

(-1, 6)

(0, 12)

(1, 24)

(2, 48)

For the second point, (0, 12) we know that when f(0) = 12

Then:

f(0) = 12 = A*(r)^0

And for every real number different than zero, a^0 = 1

Then:

f(0)  = A*1 = A = 12

Then the equation is:

f(x) = 12*(r)^x

Now we can use one of the other points, like (1, 24)

Then f(1) = 24

We can solve:

f(1) = 24 = 12*(r)^1  = 12*r

24/12 = r

2 = r

Then the equation is f(x) = 12*(2)^x

Now we need to check if this function also passes through the points (-1, 6) and (2, 24):

f(-1) = 12*(2)^-1 = 12/2 = 6

f(2) = 12*(2)^2 = 12*4 = 48

Nice.

So we can see that the function is f(x) = 12*(2)^x

Answer: 21

Step-by-step explanation: f(-2) = 4· (-2)²-(-2) + 3 = 4·4 +2 +3

Answer:

y+3=1/4(x-8)

simplified -> y+3=1/4x-2

Step-by-step explanation:

y-y1=m(x-x1)

y-(-3)=1/4(x-8)

y+3=1/4(x-8)

If you want it to be further simplified

y+3=1/4x-2

Answer:

$33.92 ($1.92 in tax)

Step-by-step explanation:

% values are 1/100ths. 32.00/100=0.32. 0.32(6) = 1.92.

 $32.00

+   $1.92

=$33.92 total.

Answer:

Answer:

in 13.95 years the senior class will have 100 students.

Step-by-step explanation:

P(h) = p(0.92)^t (equation for exponential change)

P(h) - population of highschool (or senior class) = 100

p - staring amount = 320

t = time in years

100 = 320(0.92)^t

1/3.2 = .92^t (divide both sides by 320)

log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)

13.9497 = t

Answer:

The fifth and fourth one

Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the statement that the sum of a number x and 7 is 35. Therefore, the given statement "the sum of a number x and 7 is 35" in the form of an expression can be written as,

x + 7 = 35

Subtract 7 from both the sides of the equation,

x +7 - 7 = 35 - 7

x = 28

Hence, the value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.
