Answer:
102.5
Step-by-step explanation:
125-18% or 125/1-18/100
Owen has 102.25 gm of gold.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
The rock has a mass of 125 grams.
So, the 18% of mass of rock is
= 125 - 18% of 125
=125 - 18/100 x 125
= 125 - 2250/100
= 125 - 22.5
= 102.25

1. Joshua has a ladder that is 14 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 13.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 78°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.
Answer:
Step-by-step explanation:
θ is the angle the ladder makes with the ground.
θ = arcsin(13.8/14) ≈ 80.3° > 78°
The ladder is not safe at that height and angle.

Mattie Evans drove 250 miles in the same amount of time that it took a turbo propeller plane to travel 1250 miles. The speed of the plane was 200 mph faster than the speed of the car. Find the speed of the plane.
Answer:
250 mph
Step-by-step explanation:
Speed of car = Distance / Time =
The speed of the plane was 200 mph faster than the speed of the car.
Speed of car = X mph
Speed of plane = 200 + X mph
Evans drove 250 miles in the same amount of time...
Speed = Distance / Time
Time = Distance / Speed
T = 250 / X ........(i)
same amount of time that it took a turbo propeller plane to travel 1250 miles.
Time = Distance / Speed
T = 1250 / (200 + X) .......(ii)
Substitute the value of T in eqn (i) to eqn (ii)
250 / X = 1250 / (250 + X)
250 (200 + X) = 1250 X
50000 + 250 X = 1250 X
1250 X - 250 X = 50000
1000X = 50000
X = 50000 / 1000 = 50
Speed of plane = 200 + X mph = 200 + 50 = 250 mph

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

Just read this over to see if this sounds good. It's my intro paragraph. Give me some insight if I need to change anything. Honest opinions please
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.

Which graph can be defined by the function
y=-3x + 2?
Answer:
B
Step-by-step explanation:
The second graph is the correct choice because the y-intercept is two, the graph is negative, and has a slope of m=3/1.
100 points
b) Are there any overall patterns in the data set? Striking deviations? Use mathematical reasoning to justify your answer. (2 points)
c) Calculate the measures of spread for Mrs. Hampton’s class data. Justify your response by describing the process used to find each measure. (2 points)
d) Which is a better measure of spread: range or interquartile range? Why? (2 points)
e) What does the value of the mean absolute deviation tell you about the spread of the data? (2 points)
Answer:
What the absolute deviation tells me about the spread of data is, that there is a deeper mean to the mean. First you have to find the actual mean. Next, you find the mean for the lower and upper quartiles. After that, you have to find the absolute deviation for the lower and upper quartiles.

(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.

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
