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

Step-by-step explanation:

just took the pretest got this right

Answer:

The formula for the volume of a cylinder is V=Bh (where B is the base) or V=πr2h . The radius of the cylinder is 9 ft and the height is 6 ft. Substitute 9 for r and 6 for h in the formula V=πr2h = (3.14) (9) (2) (6) =339.12

Step-by-step explanation:

Now C=339.12 round to the nearest tenth is 339.1

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)

The value of the expression for x=8 is 24

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

My Answer for your question is

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).
