5C. Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda still have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer:
20

Which of the following rotations is equivalent 270° clockwise rotation about the origin?
clockwise 270°
counterclockwise 90°
counterclockwise 360°
clockwise 90°
A rotation of 270 would be equal to 630, 990, etc. Adding 360 degrees would result in the same rotation.
Answer:

What is the most precise name for the shape of the garden? Answers: Quadrilateral, Rectangle, Square, Parallelogram (Can only pick one)
Answer:
a) The dimensions of the garden are: 4.5 ft and 5 ft
b) 22.5 ft² of fencing material
c) The most precise name for the shape of the garden is a Rectangle
Step-by-step explanation:
a) Jenna has a garden with coordinate A(2,-1), B(4,3), C(9,3), D(7,-1) where each unit is 1 foot.
What are the dimensions of the garden rounded to the nearest 10th? (Looking for the lengths of the sides)
When we are given coordinates, we find the dimensions using the formula
= √(x2 - x1)² - (y2 - y1)²
(x1 , y1) and (x2 - y2)
For side AB
A(2,-1), B(4,3)
= √(4 - 2)² + (3 - (-1))²
= √2² + 4²
= √4 + 16
= √20 units = √20 feet
= 4.472135955 feet
Approximately = 4.5 feet
For side BC
B(4,3), C(9,3)
= √(9 - 4)² + (3 - 3)²
= √5² + 0²
= √25
= 5 units = 5 feet
For side CD
C(9,3), D(7,-1)
= √(7 - 9)² + (-1 - 3)²
= √(-2)² + -4²
= √4 + 16
= √20 units = √20 feet
= 4.472135955 feet
Approximately = 4.5 feet
For side AD
A(2,-1), D(7,-1)
= √(7 - 2)² + (-1 - (-1))²
= √5² + (-1 + 1)²
= √5² + 0²
= √25
= 5 units = 5 feet
Therefore, the dimensions of the garden are: 4.5ft and 5 ft
b) If Jenna decides to buy fencing for the garden, how much fence material does she need to buy? (Free response)
To buy fencing material for the garden, we have to find the area of the garden
Formula = Length × Width
= 4.5 ft × 5 ft
= 22.5 ft²
Therefore, Jenna needs to buy 22.5 square feet of fencing material.
c) What is the most precise name for the shape of the garden?
From the above calculation, we can see that
Side AB = Side CD = 4.5 ft
Side BC = Side AD = 5 ft
Therefore, the most precise name for the shape of the garden is a Rectangle

During swim practice, an Olympic swimmer is required to complete three swimming intervals, in this order: warm-up freestyle, sprint freestyle, and cool-down breast stroke. After he completes each interval, he rests for three minutes.
Sketch a graph that represents the swimmers’ interval times with respect to swimming speed. Assign the x- and y-axes with appropriate labels. You may use description words instead of numbers to label the graph.
Answer:
I'm not sure if the warm up speed is less than the cool down speed. If it is different than how I did it you just need to swap their positions on the y axis, so the "lumps" or whatever you want to call the shapes will be in opposite positions. The middle one will stay the same because it is the fastest and in between the two happening. Also let me know if you can't read any of the labels
Find the rate of change between (3, 8) and (6, 26)
Answer:
6
Step-by-step explanation:
The slope m between the 2 points is a measure of the rate of change.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 8) and (x₂, y₂ ) = (6, 26)
m = [tex]\frac{26-8}{6-3}[/tex] = [tex]\frac{18}{3}[/tex] = 6
Then rate of change is 6
Answer please to the best of your ability
Answer:
1.8 m
Step-by-step explanation:
h(T)=-9.8T^2+20T+1
just replace the T with 2
h=-9.8(2^2)+20(2)+1
-9.8×4+40+1=1.8m

A right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.
Which of the following shapes could result from the slicing?
triangle
O rectangle
O square
O pentagon
A triangle is obtained when a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.
A rectangular pyramid is a three-dimensional object with a rectangle base and a triangular face corresponding to each of the sides of the base.
Cross - sections perpendicular to the base and through the vertex will be triangles. A triangle is obtained as a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.

(Also this answer is for Part E)
Answer: A) The histogram is skewed left meaning that the median will be more than the mean of the data. As the study goes onward in terms of age, more and more children are studied to play at least an hour a week of video games. Barley any children below the age of 5 play video games for at least an hour a week, but once they hit the age of 6, more and more kids are playing video games. Kids aged fifteen to seventeen have the most amount of kids that do play at least an hour of video games per week. In a graph, this may show a J-shaped curve that starts low, then has a large increase to eventually level off and begin gradually getting larger as the ages increase.B) The following statement, “Children are typically introduced to video games between the ages of six to eight” is a true statement. The graph shows that a very small percentage of children from birth to five years old play video games, but suddenly, once they have turned 6, there is practically a 60% increase in how many kids are playing video games one hour a week. It is from the age 6 that the kids start off and are introduced to the video games, as more and more kids end up playing as well as the grow older.c) Knowing that five hundred families that lived in varied cities were randomly surveyed for this data, then it is possible to make a valid conclusion. To make accurate and valid conclusions, the data should be a good representation of the overall population, one that is large and random. The data collected was not all from one specific area, and instead was from a large sample size from different cities are regions all over. This was also done randomly, and did not only focus on people more or less likely to play video games. This means that it is possible to make valid conclusions.

People of the past and present judge each other by their class. This could relate to how much wealth they have as well as their social class or economic status. These judgments separate us as a society, and we live our lives around these judgments. Class, in simple words, is a group of people or things categorized by the quality and economic status. This relates to the novel The Great Gatsby by some of the characters in the novel, such as Tom and Daisy Buchanan who are sardonic and in love with material luxury.
·
Daisy Buchanan is a beautiful, charming woman from Louisville, Kentucky. For a while, she was with Gatsby before he went to war but later married Tom Buchanan because he had a promised wealthy life that he could provide her. In the novel, during the reunion at Daisy's house in the east egg, "'You make me feel uncivilized, Daisy,' I confessed on my second glass of corky but rather impressive claret. 'Can't you talk about crops or something?'" Nick's statement shows the wealthy class of the east egg and how Daisy flaunts her wealth to everybody instead of enjoying the people around her.

A cube-shaped box has a volume of 27 cubic inches. If the box is packed full of cubes with edge lengths of 1 inch, how many cubes can fit along one side of the
box?
Answer:
9 along one side.
Step-by-step explanation:
This question may be a bit tricky.
The side should mean the entire side, not just along the bottom edge.
The bottom row will have three 1-inch cubes. Three more in a middle row, and three more on top of that. That is a total of nine on that side.

Answer:
(0, 23)
Step-by-step explanation:
find the value of the variables
Answer:
x = 50 degrees
y = 105 degrees
Step-by-step explanation:
to find y, take 75 and subtract it from 180:
180 - 75 = 105
y = 105 degrees
to find x, take 180 and subtract 75:
180 - 75 = 105
then, subtract 5 from 105:
105 - 5 = 100
next, divide 2 from 100:
100 / 2 = 50
x = 50 degrees
