Please Help!!!!!What is the area of the polygon below?
Answer:
48 mm squared
Step-by-step explanation:
divide the shape into 3 parts- left square, middle joining rectangle, and right rectangle
a) the right most square has an area of 4 by 4 ie 16 mm sq.
b) the middle adjoining rectangle and length of 2 mm and breadth of 1mm making its area 2mm sq.
c) the right rectangle has height 5 mm nad breadth 6mm making the area 30 mm sq.
adding parts a b and c the total area is 16+2+30 = 48 mm squared
Answer:
48 square mm
Step-by-step explanation:
see attached image
We have 3 rectangles now.
16+2+30
=48
So, the area is 48 square mm.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Can you please help find z?
Answer:
the angle for z° is 96°
Step-by-step explanation:
Since we already know 2 of the angles and that y=18° because both of the lines opposed to y are straight, so subtract all of what we know: 360-(64+18+18)=260°. x also has straight lines with the 64°, so subtract another 64°, then the equation will be 360°-(64+64+18+18), so z should equal 196, but there are 2 z angles, so divide it by 2 and the answer should be z°=96°
Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.
Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.
Part B: Find side AB. Show each step of your work.
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively. The length of side \(AB\) is approximately \(3.36\) feet.
What is the line segment?Part A:
To draw triangles \(ABC\) and \(DEC\) separately, follow the steps below:
Draw a straight line segment DE with length \(1.8\) feet.
From point D, draw a line segment DC perpendicular to DE with length 4 feet.
Connect point E and point C with a straight line segment EC.
From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.
Draw a straight line segment BC that intersects line segment DC at point A.
Connect point A and point B with a straight line segment AB.
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively.
Part B:
Since triangles \(ABC\) and \(DEC\) are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:
\(AB/DE = BC/EC\)
Substituting the given values, we get:
\(x/1.8 = BC/0.8\)
Solving for BC, we get:
\(BC = 0.8x/1.8\)
Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:
\(BC^2 + EC^2 = DE^2\)
Substituting the given values, we get:
\((0.8x/1.8)^2 + 4^2 = 1.8^2\)
Solving for x, we get:
\(x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8\)
\(x \approx 3.36 feet\)
Therefore, the length of side \(AB\) is approximately \(3.36\) feet.

Using inverse operations is a direct way to solving equations
What is the Golden Rule for solving equations?
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

Triangle JKL has vertices at J(−1, −5), K(−2, −2), and L(2, −4). Determine the translation direction and the number of units of the image of triangle JKL if vertex J′ is at (−1, −8).
3 units down
3 units up
7 units to the right
7 units to the left
Answer:
3 units down
Step-by-step explanation:
J(-1, -5) → J'(-1, -8)
The x coordinate of the vertex J is -1 and does not change in J' (it is still -1)
The y coordinate of J is -5, and for J' is -8. This means the translation direction of 3 units down. (-8- -5 = -3)
what is the radius of a button if the circumference is 3 1/2 in
Answer: 0.557 in
Step-by-step explanation:
We will use the formula for the circumference of a circle, substitute known values, and solve for r (radius). 3 1/2 = 3.5.
Given:
C = 2πr
Substitute known values:
(3.5) = 2πr
Divide both sides of the equation by 2π:
(3.5) = 2πr
r = 0.557 in

What is the price of the missing price of the pounds?
Answer:
$17.50
Step-by-step explanation:
You have a table with a proportional relationship between weight and price, and the pair (weight, price) = (2 lb, $7.00) given. You want to know the price for a weight of 5 lb.
ProportionA proportion that can be used to find the missing price is ...
price/weight = x/(5 lb) = ($7.00)/(2 lb)
Multiplying by 5 lb gives ...
x = $7.00 × (5 lb)/(2 lb) = $17.50
The price for 5 lb is $17.50.

Angela and Tyler are selling tickets for a charity football game. Students will get a discount for the game. Angela sells 6 adult ticket and 10 student ticket for $122. Tyler sells 11 adult tickets and 5 student tickets for a total of $157. What is the of an adult ticket and what is the price of a student ticket?
A, Define your varibles and write a system of equations that represents the ticket sales for both Angela and Tyler.
let x=
Let y=
system of equation:
B' Solve system of equation
c' Write answer using a complete sentence.
Answer:
Step-by-step explanation:
Let’s say that the price of an adult ticket is x and a student ticket is y.
we know that 6 adult tickets (6x) and 10 student tickets (10y) equal 122, so 6x+10y=122. Then, 11x+5y=157
6x+10y=122
11x+5y=157
Multiply the first equation by -1/2 and add it to the second to cancel out the y
8x=96
x=12
Plug this back in to equation 2 to find y
132+5y=157
y=5
Checking this with the first equation, it all works out.
The price of an adult ticket for a charity football game is $12, while the price for a student ticket for the same game is $5
