A polygon is shown on the graph:
What effect will a translation 3 units down and 2 units left have on the polygon? Be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image.
Worth 100 points!
so translation means that the points are moving on the graph
so the shape is moving down three then left two
it doesn’t change the shape in any way it just moves the shape
so all the sides and angles are the same
so the polygon is completely congruent with the premise and image since the shape didn’t change

2. 36 - 18r = 4 (3 + r)
3. 4 (4p +3) = 8p + 16
4. 15a + 60 = 12a -84
Answer:
1. x=28
2. r=1+1/11
3=p=1/2
4=a=-48
Step-by-step explanation:
1.
9x-12=8x+16
We move all terms to the left:
9x-12-(8x+16)=0
We get rid of parentheses
9x-8x-16-12=0
We add all the numbers together, and all the variables
x-28=0
We move all terms containing x to the left, all other terms to the right
x=28
Which of the following is a line segment as shown in the drawing?
Answers:
- DH is correct because a line is connecting the two points D and H as shown in the image, forming a line segment.
- ED is correct because a line is connecting the two points D and E, forming another line segment, as shown in the drawing.
- EH is incorrect because in the drawing shown, there is no line connecting the two points E and H, so there would be no line segment formed between these two points.
- CD is correct because there is another line connecting the two points C and D, forming another line segment in the drawing.
Therefore, lines DH, ED, and CD are all line segments.
samantha spent $15.88 at a department store. she spent half as much at the bookstore as she did at the department store. she then spent $12.64 at a restaurant. she now has $33.85 left in her purse. how much did she have to begin with?
Answer:
39.845
Step-by-step explanation:
this question it is asking how much money she has at the beginning, so to solve this we need to add up the money she spent before and add the money she has left.
1. we are ready to know she already spends 15.88 at the beginning and then she spent half as much as 15.88 so, we have to divide 15.88 by 2.
15.88/2= 7.94
2. now everything is figured out, next, add them together.
15.88+7.94+3.385= 39.845
A circle has a diameter of 8 inches. What is the area of this circle? Use 3.14 for pi.
(100 POINTS I NEED THE ANSWER SO I PASS THIS YEAR)
Given that a circle has a diameter of 8 inches and we are required to find its area using 3.14 as pi.
We know that the formula for calculating the area of a circle is A = πr², where A is the area, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Since we are given the diameter of the circle, we can calculate its radius using the formula: radius (r) = diameter/2
Therefore, the radius of this circle is: r = 8/2 = 4 inches
Now, we can calculate the area of the circle using the formula: A = πr² Substituting the value of r, we get: A = 3.14 x 4² A = 3.14 x 16 A = 50.24 square inches
Therefore, the area of the circle is 50.24 square inches.
The answer is:
50.24 in²Work/explanation:
The formula for the circle's area :
\(\sf{A=\pi r^2}\)
where :
A = areaπ = 3.14r = radiusWe know the diameter, but the radius is one-half of that, so the radius is :
Radius = Diameter ÷ 2 = 8 ÷ 2 = 4 inchesHere's a diagram for better understanding:
\(\setlength{\unitlength}{1.1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\small 4\ in}\end{picture}\)
Now, plug in the data:
\(\large\begin{gathered}\bf{A=\pi r^2}\\\\\bf{A=3.14\times4^2}\\\\\bf{A=3.14\times16}\\\\\bf{A=50.24\:in^2}\end{gathered}\)

Place the dot in the middle of -1 and -2!
Step-by-step explanation:
You have to add 2 -2 2/6 and 5/6 that will get you -1 3/6. Then you have to find where it goes. If you would simplify the number you would get -1 1/2. This means the dot would be placed in the middle of 2 numbers. Since it is 1 and 1/2 you would need to place it between -1 and -2.

Colton practices the piano 413 minutes in 1 week. If t represents the total time he practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.
Answer:
lk
Step-by-step explanation:
Answer:
Colton practices 59 minutes each day. So, 413= 59t x 7d.
Step-by-step explanation:
There are 7 days in a week and Colton practices 413 minutes in that amount of time. So to put it simple you just do 413 divided by 7 and you get 59. To check this you can do 59 times 7 and you'll get 413. Then you just put it in the correct equation.

1.48+103+c=180(sum of the interior angles of a triangle)
151+c=180
c=180-151
c=29 degree
2.angle D+angle E=90(in complementary angles sum of two agles is 90 degree)
52+angle E=90
angle E=90-52
angle E=38 degree
3.angle F+angle G
=145+35
=180 degree
yes they are supplementary angles because in supplementary angle sum of two angles is 180 degree)
4.a.radius=diameter/2

=3.14*64
=200.96 ft^2
6.yes 3,4 and 5 forms a triangle because the sum of two first number is greater than third side.
Answer:
hope it helped :)
Step-by-step explanation:
1)
In ΔABC , sum of angles = 180°
∠A + ∠B + ∠C = 180
48 + 103 + ∠C = 180
∠C = 29°
2)
∠D and ∠E are complementary angles. That is sum of ∠D and ∠E = 90
∠D + ∠E = 90°
52 + ∠E = 90
∠E = 38°
3)
∠F + ∠G = 145 + 35 = 180°
Since sum of angles is 180° , they are supplementary angles.
4)
a) diameter , d = 16 ft => radius = 16/2 = 8ft
b) circumference, c =π d = 3.14 x 16 = 50.24ft
c) Area = π \(r^2\) = 3.14 x 8 x 8 = 200.96 square feet
5)
a) ∠M = 72°
b) \(\frac{15}{5} = \frac{8}{x}\)
\(x = \frac{8 \times 5}{15} = \frac{40}{15} = \frac{8}{3}\)
6)
For the given lengths to be a triangle. sum of squares of small sides must be equal to square of larger length. That is,
\(5^2 = 4^2 + 3^2\\25 = 16 + 9\\25 = 25\)
And it's true. So the lengths make a triangle.

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
