Answers

Answer:

Step-by-step explanation:

10.   To solve for this, use the formula: 180*(n-2)

So, 180(n-2) = 2,340

Once n is solved for, that is the number of sides

11. Use the formula:

[180*(n-2)]/n

    (n represents the number of sides)

Find the area of the composite figure?


Answers

Answer:

128

Step-by-step explanation:

Let's start by figuring out the last side of the triangle

we can use the pathagoryous theroem and get

11.9²+x²=16.9²

Solve this and get x=12

Let's now compute the area of the triangle

b*h*.5

12*11.9*.5=71.4

So 71.4 is the area of the triangle

we now need to find the area of the semi circle.

to do this we are going to find the area and then divide it by 2

We know that the length is equal to 12 which means that the radius is 6

so we have

π6²/2

which is 56.55

We add the 71.4+56.55= 127.94 which rounds to 128

Answer:

212.758

Step-by-step explanation:

Find the semi-circle first, the diameter is 16.9 ft.

To find area:

Formula:

pi x radius x radius x 1/2

16.9 ÷ 2 = 8.45 (radius)

22/7 x 8.45 x 8.45 = 224.407 (Circle)

224.407 ÷ 2 = 112.203 (Semi circle)

Find the triangle:

1/2 x base x height or length x base x height

But for now, we will use the first one.

1/2 x 16.9 x 11.9 = 100.555

Now add them up.

100.555 + 112.203 = 212.758

10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?

Answers

Answer:

(2n -3) + n = 102

2n - 3 + n = 102

3n - 3 = 102

3n = 105

n = 35 (the first number)

SO...

The other number is (2 x 35) - 3 =

                                           70 - 3 = 67 (the second number)

The numbers are 35 and 67.

35 + 67 = 102 CHECK!

What are like and unlike terms in an expression?

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions

Given here: The expression as 7a-4a

Now combining the like terms we get

7a-4a=3a

for a=8

we have

3a=3×8

   =24

Hence, The value of the expression for x=8 is 24

Answer:

x+4 and y+3

Step-by-step explanation:

Both the x and y values move in positive directions from the first triangle to the second.

Answer:

(x+4, y+3)

Step-by-step explanation:

First, choose a point to follow (I chose C).  The coordinates of C are (-2, -5).  The coordinates of C' are (2, -2).  To get to 2 from -2, you have to add 4.  Move left or right because it's on the x-axis.  Since it's moving you the right, it is positive.  So, x+4 is the first part.  To get from C to C', you have to move up to follow the y-axis, meaning another positive.  Counting the units from (2, -5), because that is the point after x+4, there are 3 units.  So, (x+4, y+3).

At a hot dog stand they serve regular hot dogs and footling hot dogs at a ratio of 5 to 3. Based on this ratio how many footlong hot dogs will be served if there is a total of 120 hot dogs served.

Answers

Answer:
45
Step-by-step explanation:
Ratio is 5:3
So total ratio "parts" is 5 + 3 = 8
In total there are 120 dogs served, so each part is:
120/8 = 15 dogs
Since, footlong hot dogs are "3" parts, and each part is 15 dogs, there will be:

3 * 15 = 45 footlong hotdogs

On top of that, there's an extra $9,000 for every Japanese airplane you destroy -- no limit.That's the deal -- in inflation-adjusted 2020 dollars -- that a few hundred Americans took in 1941 to become the heroes, and some would even say the saviors, of China.Those American pilots, mechanics and support personnel became members of the American Volunteer Group (AVG), later known as the Flying Tigers.The group's American-made warplanes featured the gaping, tooth-filled mouth of a shark on their nose, a fearsome symbol still used on the US Air Force's A-10 ground-attack jets to this day.Flying Tiger pilot Robert T.
