What is the sum of the measures of the interior angles of a 7-gon?

Answers

Answer:

900°

Step-by-step explanation:

What is the sum of the measures of the interior angles of a 7-gon?

The formula to measure the interior angles of a polygon

= (n- 2) × 180 °

Where,

n = number of sides

We are given 7 - gon

This means it has 7 sides = Heptagon

Hence,

The measure of the interior angle is given as:

(7 - 2) × 180°

= 5 × 180°

= 900°

The sum of the interior angles of a 7-gon is 900°

3.6x+5.9−2.2−1.7x

Answers

Answer:

1.9x+3.7

Step-by-step explanation:

Subtract 3.6x-1.7x

and 5.9-2.2    

The solution is 1.9x + 3.7

The value of the equation is given as A = 1.9x + 3.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 3.6x + 5.9 - 2.2 - 1.7x   be equation (1)

On simplifying the equation , we get

On grouping the similar terms

The value of A = ( 3.6x - 1.7x ) + ( 5.9 - 2.2 )

The value of A = 1.9x + 3.7

Therefore , the value of A is 1.9x + 3.7

Hence , the equation is A = 1.9x + 3.7

Answers

Answer:

2 or C

Step-by-step explanation:

I'm taking this to mean

4 = 2(x - 1)^2

4 = 2(x^2 - 2x + 1)

4 = 2x^2 - 4x + 2

2x^2 - 4x - 2  =  0

x^2 - 2x - 1 = 0

What you get from here is sqrt(2) as one of the roots.

That is not nearly an answer.

4 = 4(x -1)

4 = 4x - 4

8 = 4x

x = 8/4

x  =  2

That makes C the answer.

“How many 2/5 are in 1?”

I love the easy ones!

The real math folks generally ignore them I guess because the easy ones are not worth their time, leaving said easy ones to dilettantes like me, who then look smarter-than-I-really-am to the noobies.

Love the easy ones.

So, to the question: How many two-fifths are in one?

Well now. How shall we handle this? Hmm…

I know! Let's count the fifths (just numbers, no booze), because it's probably as good a way of getting to an answer as any other way, the question is about fifths, and counting the fifths will at least give us a picture of what we're dealing with here.

Let's jump ahead, to see where we want to end up:

We want to end up with five fifths, also known as 5/5, because 5/5 is the same as 1. How do I know that 5/5 is the same as 1? Well, I know (you'll just have to trust me on this) because saying “5/5” is the same as saying “5 divided by 5”, and saying “1/2” is the same as saying “1 divided by 2", and so on. This is true for all fractions.

So: if 5/5 is the same as 5 divided by 5, then 5/5 equals 1. (You can see why, right? Any number divided into itself is equal to one; also, five goes into five exactly one time!).

And counting the fifths,

1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 = 1

Or, to count them another way,

1/5 + 1/5 = 2/5

2/5 + 1/5 = 3/5

3/5 + 1/5 = 4/5

4/5 + 1/5 = 5/5

Now that we can see what's inside of that 5/5, let's count how many two-fifths are in five-fifths by adding 2/5 together until we get as close to 5/5 as possible without going over:

2/5 + 2/5 = 4/5

leaving just 1/5 remainder, meaning that there are two 2/5 in 5/5.

We can see that that is true and correct by looking at our little counting exercise above.

Now to make sure our reasoning is clear let's count our fifths again, this time slightly rearranging the way we write the numbers, and then taking things one step further:

(1/5 + 1/5) + (1/5 + 1/5) + 1/5 = 5/5

(2/5) + (2/5) + (1/5) = 5/5

And there it is: there are two 2/5 in 1!

So let's complete the addition for the sake of those like myself who need to see these things through to their furthest conclusion:

(2/5) + (2/5) + (1/5) = 5/5

4/5 + 1/5 = 5/5

5/5 = 5/5

5/5 = 1

1 = 1. And 2/5+2/5=4/5.

A side of the triangle below has been extended to form an exterior angle of 164". Find
the value of x.
1649

Answers

Given:

Measure of exterior angle = 164°

The measure of opposite interior angles are x° and 53°.

To find:

The value of x.

Solution:

According to the Exterior Angle Theorem, in a triangle the measure of an exterior angles is always equal to the sum of measures of two opposite interior angles.

Using Exterior Angle Theorem, we get

[tex]x^\circ+53^\circ=164^\circ[/tex]

[tex]x^\circ=164^\circ-53^\circ[/tex]

[tex]x^\circ=111^\circ[/tex]

[tex]x=111[/tex]

Therefore, the value of x is 111.

The length of an island is decreasing a rate of 16 inches per year. How many years will it take for the change in length of the island to be -364 inches? Answer value

Answers

Answer: 23 years

Step-by-step explanation:

From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:

= 364 / 16

= 22.75 years

= 23 years approximately

36/42 = 24/r what is r

Answers

Answer:

r=28

Step-by-step explanation:

36/42 = 24/r (determine the defined range)

36/42 = 24/r , r ≠ 0 ( Reduce the fraction)

6/7 = 24/r (cross multiply)

6x = 168 ( divide both sides)

r=28 , r ≠ 0

Answer:

r = 28

Step-by-step explanation:

Cross multiply and solve for r:

[tex]\frac{36}{42}[/tex] = [tex]\frac{24}{r}[/tex]

36r = 1008

r = 28

So, r = 28

how do i solve -3x + 2y = -4

Answers

Answer:

y= 3/2 x -2

Step-by-step explanation:

I guess you want to find the y=mx+b form

So you do +3x on both sides which will gave you: 2y= 3x-4

Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2

So 3/2 is the fraction like the answer above and -4/2 = -2

The school is landscaping an area for a soccer field. If the
dimensions are 60 feet by 35 feet. What is the area of the soccer
field?

Answers

Answer: 2100 square feet

Step-by-step explanation: 60 x 35=2100

Answer:

2100 ft squared!

Step-by-step explanation:

The formula to find the area of a rectangle is L * W = A

Where A is the total area, and L and W are the dimensions.

Since we know what the dimensions of the rectangles are, we can replace L and W to find out the area. This will look like this: 60 * 35 = A

Now we just have to multiply 60 and 35 to find A. This will simplify to 2100, which means the total are of the rectangle, or in this case, the soccer field, is 2100 ft squared!
