Answer:
10 units
Step-by-step explanation:
You can create point c at (3,4) to make a right triangle
Then you know that the 2 legs are 6 and 8
We need to find the hypotenuse
You can use pythagorean theorem:
6^2+8^2=c^2
So c=10
So the distance is 10 units

What is the area of the polygon in square units?
Answer:
(d) 80 square units
Step-by-step explanation:
As with many composite area problems, this can be worked any of several ways. The attached shows trapezoid ABCE, from which triangle CDE can be removed to get the desired area.
The relevant formulas are ...
A = (1/2)(b1 +b2)h . . . . . . area of a trapezoid
A= (1/2)bh . . . . . . . . . . . . area of a triangle
__
Here, the trapezoid has bases 12 and 2, and height 12, so its area is ...
A = (1/2)(12 +2)(12) = 84 . . . . square units
The triangle has a base of 4 and a height of 2, so its area is ...
A = (1/2)(4)(2) = 4 . . . . square units
Then the area of the desired figure is ...
84 - 4 = 80 . . . . square units

Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6) Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%
Marks books has an area of 48 in.². The perimeter of the book is 52 inches. what are the dimensions of the book
Answer:
dimensions of the book are 2 in. by 24 in.
Step-by-step explanation:
I assume the book is a rectangle
Let w = the width
l = the length
A = lw = 48 P = 2w + 2l = 52
w + l = 26
l = 26 - w
w(26-w) =48
26w - [tex]w^{2}[/tex] = 48
[tex]w^{2} - 26 w + 48 = 0[/tex]
(w-2)(w -24) = 0
w = 2 or w = 24
if w = 2, then l = 26 - 2 = 24
if w = 24, then l = 26 - 24 = 2
So, the dimensions of the book are 2 in. by 24 in.

How do I find out the answer for this equation?
1/72 x 648
Answer:
The answer is 9
Step-by-step explanation:
Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying
[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.
Hope this helps!
Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3). Determine the point of intersection of the medians, and state the coordinates
Answer:
(-5, 3)
Step-by-step explanation:
Let O(x, y) be the centroid of the triangle.
The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.
The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.
For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:
[tex]x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3[/tex]
The centroid is at (-5, 3)

The sum of two numbers is 68. Their difference is 15. Write a system of equations you could use to solve this problem.
Answer:
x+y=68
x-y=15
Step-by-step explanation:
A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".
The mean of six numbers is 14. If one of the six numbers is removed, the mean becomes 5. What is the value of the number removed?
Answer:
Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.
Step-by-step explanation:
Hope I helped.It's just a reminder of helpful things for means!
Answer:
59
Step-by-step explanation:
Suppose a, b, c, d, e and f represent the 6 numbers.
Then, [tex]\frac{a + b + c + d + e + f}{6} = 14\\[/tex]
(1) a + b + c + d + e + f = 84
Let's remove f
then [tex]\frac{a + b + c + d + e}{5} = 5[/tex]
(2) a + b + c + d +e = 25
Substitute 25 in for a + b + c + d +e in equation (1)
We have 25 + f = 84
f = 59
