which graph shows the image of the triangle after transforming at using the rule Z (x,y) (x,-y)
Answer:See the attached figure. The original triangle is shown in red (triangle ABC). The line of reflection is the blue dashed line. This is the equation y = x. Reflecting triangle ABC over the line y = x results in the purple triangle A'B'C'.
Note how the x and y values swap places.
We have...
point A = (5,1) turn into point A' = (1,5)
point B = (8,1) turn into point B' = (1,8)
point C = (8,6) turn into point B' = (6,8)
The swap occurs because the rule (x,y) --> (y,x) tells this to happen.
The purple triangle is the final answer.

The area of the base and total surface area of a square based solid pyramid are 144 sq. cm and 384 sq cm respectively. What will be the volume of the pyramid? Find it
Answer:
384 cubic centimeters
Step-by-step explanation:
We are given the base area and total area of a square pyramid and asked to find the volume. The typical volume formula for a pyramid requires that we know the height of it. We can use the formula for the surface area to find the slant height of a face, and we can use the slant height to find the height perpendicular to the base.
__
face areatotal surface area = base area + area of 4 faces
area of 4 faces = total surface area - base area
area of 4 faces = 384 cm² -144 cm² = 240 cm²
area of 1 face = 240 cm²/4 = 60 cm²
__
slant heightThe side length of the square base is ...
A = a²
a = √A = √(144 cm²) = 12 cm
and the slant height of one face is ...
A = 1/2as
s = (2A)/a = (2×60 cm²)/(12 cm) = 10 cm
__
pyramid heightThe distance from the center of the base to the edge of the base is (12 cm)/2 = 6 cm. That is one leg of the right triangle whose hypotenuse is the slant height of the face. The other leg of the triangle is the height of the pyramid:
H² = s² -(a/2)² . . . . Pythagorean theroem solved for one leg
H = √(10² -6²) = 8 . . . . cm . . . . height of the pyramid
__
volumeNow we know the base area of the pyramid (B), and we know its height (H), so we can use the formula ...
V = 1/3BH
V = 1/3(144 cm²)(8 cm) = 384 cm³
The volume of the pyramid will be 384 cm³.
The ballfield has a concession stand where they sell snow cones for $0.50 each. The ingredients to make the snow cones costs $9 each day. They usually sell 35 snow cones per day. On Friday, it rained, and they only sold 20 snow cones. How much profit did the concession stand make after expenses that day?
Answer:
$4,86
Step-by-step explanation:
Profit without expenses - $0,50×20 snow cones
=$10
Let's calculate the percentage the seller takes for the ingredients daily
The seller per day makes-$0,50×35 snow cones=$17,5
This means the percent he takes for the ingredients from his/her $17,5 daily is- $9÷$17,5 ×100=51,4%.
NB-the 51,4% is the percentage of money he/she takes from the $17,5 everyday
Therefore if on the raining day he made $10
Then $10×51,4÷100=$5,14
NB-the $5,14 is the money he will take for the ingredients on the raining day
Therefore $10-$5,14=$4,86
Therefore the total profit he made with expenses is $4,86

Help please really important!! Will make brainiest
Answer:
This is all I have right now. The ray makes me think about drawing a circle in the middle and somehow using the diameter to find the height of the triangle. It's just weird because we don't know the base and I'm not sure how to find that without at least knowing the height & using pythagorean theorem.
Although it's not much, hopefully this can steer you in the right direction! Maybe you're way smarter than me and know where to take it from here lol Good luck

When you list all of the possible outcomes in a sample space by following an organized system (an orderly process), it is called a systematic list. There are different strategies that may help you make a systematic list, but what is most important is that you methodically follow your system until it is complete.
To get home, Renae can take one of 4 buses: #41, #28, #55, or #81. Once she is on a bus, she will randomly select one of the following equally likely activities: listening to her MP3 player, writing a letter, or reading a book.
a. Create the sample space of all possible ways Renae can get home and do one activity by making a systematic list.
b. Use your sample space to find the following probabilites:
i. P(Renae takes an odd-numbered bus)
ii. P(Renae does not write a letter)
iii. P(Renae catches #28 bus and then reads a book)
c. Does her activity depend on which bus she takes? Explain why or why not.
Answer:
Part (a)
see attached for sample space
Part (b)
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Total number of possible outcomes = 12
[tex]\textsf{P(Renae takes an odd-numbered bus)}= \dfrac{9}{12}=\dfrac34[/tex]
[tex]\textsf{P(Renae does not write a letter)}= \dfrac{8}{12}=\dfrac23[/tex]
[tex]\textsf{P(Renae catches no.28 bus then reads a book)}= \dfrac{1}{12}[/tex]
Part (c)
Her activity does not depend on which bus she takes, as we have been told that once she is on the bus, she randomly selects the activity. Therefore, the activity selection is independent from the bus selection.
The sample space confirms this as it shows that the probability of the selecting each activity is equally likely for each of the 4 buses.

Answer:
answer is either 1 or 3.5
Step-by-step explanation:
first you need to add all of the numbers together then divide by the amount of numbers ( in this case there are 4 numbers)
2+5+4+3=14
14/4=3.5 which gets you the mean
but sometimes it will want you to go a step further and do this-
finding the distance from each number from the mean found like this!
3.5-2=1.5
5-3.5=1.5
4-3.5=.5
3.5-3=.5
then add these together
1.5+1.5+.5+.5=4
then 4 divided by tghe amount of numbers which is 4
4/4=1 so that is taken a step further but the answer is either
An art teacher had 2/3 gallons of paint to pour into containers. If he poured 1/8 gallon of paint into each container until he ran out of paint, how many containers had paint in them, including the one that was partially filled?
6 containers have paint in them.
Step-by-step explanation: Firstly we must convert them to similar fractions, so times the denominator of each fraction by the denominator and numerator of the other fraction (the denominator is the bottom number and the numerator is the top number.) So 3 times 1 is 3, 3 times 8 is 24, so the fraction of paint poured into each container changes to 3/24. 8 times 2 is 16, 8 times 3 is 24, so the total amount of paint poured is 16/24, divide the numerator of paint poured by the numerator of paint in each container, so 16 divided by 3, you get 5 remainder 1, the remainder 1 still counts as part of the next container so 6 container have paint in them.

I think of a number. If I subtract 9 from it and multiply this difference by 4, the
result is 128.
Answer:
you were thinking of 41
Step-by-step explanation:
(x-9)*4=128
(x-9)=128/4
(x-9)=32
x=32+9
x=41
Answer:
41
Step-by-step explanation:
Let n be the number
Subtract 9
n-9
Multiply this by 4
4(n-9)
The result is 128
4(n-9)=128
To find the number divide each side by 4
4(n-9)/4=128/4
n-9 = 32
Add 9 to each side
n-9+9 = 32+9
n = 41

How many ounces of pure alcohol should be added to 500 ounces of 35 % alcohol solution to produce a solution that is 50 %?
Pesent your answer as an integer or a reduced fraction. Do not use decimals.
Answer:
150 ounces
Step-by-step explanation:
It is convenient to write an equation for the total amount of alcohol in the mix.
__
Let x represent the amount of pure alcohol added. Then the amount of alcohol in the mix is ...
500(35%) +x(100%) = (500 +x)(50%)
x = 500(15%) +x(50%) . . . . . . . subtract 500(35%)
x(50%) = 500(15%) . . . . . . . . . . subtract x(50%)
x = (500)(15%)/(50%) = 150 . . . . divide by the coefficient of x
150 ounces of pure alcohol should be added to produce the desired solution.
The sum of two consecutive odd integers is 96. what is the product of these integers?
Answer:
47 and 49
Step-by-step explanation:
Answer:
2303
Step-by-step explanation:
Let the smaller of the two odd integers be x.
Then the next odd integer is x + 2.
Since the sum of these 2 integers is 96, we may write x + (x + 2) = 96
Now solving for x we obtain:
2x = 94
x = 47
To find the next value we can subtract 47 from 96, which is 49.
Hence, the required two integers are 47 and 49. Multiplying them, we get a product of 2303.

What do scientists believe are the descendants of dinosaurs?
A. Fish
B. Birds
C. Chimpanzees
D. Rats
Answer:
B
Birds are related to theropod dinosaurs — a group that includes the Tyrannosaurus rex.
Theropods were bipedal dinosaurs, meaning they walked on two legs, not four like many other dinosaurs. When we look at the modern-day emu or ostrich, the resemblance to these dinosaurs is striking, especially when examining their bone structure.
Birds have scales like many dinosaurs and some dinosaurs may have had feathers.
Scientists have discovered that the tissues used to produce scales in reptiles are similar to those that produce feathers in birds. This suggests that there is a common ancestor between dinosaurs, birds, and reptiles. Furthermore, birds have scales on their feet!
Birds lay eggs similar to dinosaurs and reptiles.
The similarities between bird and reptile eggs are well known, but they also share traits with dinosaur eggs.
Most dinosaur eggs are hard-shelled, just like the eggs of our modern-day feathered friends. They are also both made up of the same basic elements, calcium, and carbon, which form crystal structures that make the eggshell more difficult to crack.
