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
(I don't know what units you to put for your answer since I don't learn American mathematics, so it's up to you)

what is the value of p so that the expession 6x+3-(8x-5) is equivalent to (px+8)?
Answers
Answer:
-2
Step-by-step explanation:
The first equation simplifies to -2x+8 so p should be replaced with -2
The value of p so that the expression 6x+3-(8x-5) is equivalent to (px+8) is, -2
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
An expression, 6x+3-(8x-5)
another expression, (px+8)
Value of p for which both the expressions are equivalent = ?
So now, we can compare both the expressions
⇒ 6x+3-(8x-5)
⇒ 6x+3-8x+5
⇒ -2x+8
if compare it with (px+8)
then, p = -2
Hence, the values of p is -2

How to calculate 46% of 50
Answers
Answer:
the answer is 23
Step-by-step explanation:
100/50=2
46/2=23
Answer:
23
Step-by-step explanation:
50/x=100/46
(50/x)*x=(100/46)*x - we multiply both sides of the equation by x
50=2.17391304348*x - we divide both sides of the equation by (2.17391304348) to get x
50/2.17391304348=x
23=x
x=23
now we have:
46% of 50=23

A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *
Answers
Answer:
(x, y) → (4x, 4y)Step-by-step explanation:
Dilation is applied by the rule:
(x, y) → (kx, ky), where k is the scale factorWe have
(x, y) = (-2, 3) and (kx, ky) = (-8, 12)Substitute and solve for k
-8 = -2k and 12 = 3k ⇒ k = 4So the rule is

Which ordered pair describes a point that is located 5 units to
the right of the origin and 2 units below the x-axis?
Answers
Answer:
(5,-2)
Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .
The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).
What is the coordinate grid?A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.
Given a statement for coordinates a point that is located 5 units to
the right of the origin and 2 units below the x-axis,
so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.
5 units to the right, which is the coordinate of x is 5
and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,
2 units below the x-axis, which is coordinate of y is -2
point is (5, -2).
Hence the coordinates of points are (5, -2).

180-73-13=94
Answer: X = 89°
Step-by-step explanation:
At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)
Answers
Answer:
(3,-4)
Step-by-step explanation:
You can find the vertex where x = -b/2a
To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c
y = 2(x^2 - 6x + 9) - 4
y = 2x^2 - 12x + 18 - 4
y = 2x^2 - 12x + 14
In this equation, a = 2 and b = -12.
So let's plug that into x=-b/2a
x = -(-12)/2(2)
x = 12/4
x = 3
Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.
y = 2(x - 3)^2 - 4
y = 2(3 - 3)^2 - 4
y = -4
