Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
I hope that helps!
Answer:
6:59am
Step-by-step explanation:
1 hour and 33 minutes = 93 minutes
55 minute ride to museum
93+55=148
60 minutes in 1 hour
148 divided by 60 = 2 hours 46 minutes
Time Left: 9:41
9.41-2.46
6.59
They left at 6:59am
(0.35 + 5.2) x. =27.75
To solve this linear equation, we can re arrange the numbers.
Q) (0.35 + 5.2) x = 27.75
Ans. x (0.35 + 5.2) = 27.75
0.35x + 5.2x = 27.75
5.55x = 27.75
x = 27.75/5.55 = 5
x = 5

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.
Can someone please help me i am so confused.
Answer:
0.25
Step-by-step explanation:
If the person made it 105 out of 140 times, that can be written as a fraction: 105/140
Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.
105 divided by 140 = 0.75
0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25
Hope this helps
The experimental probability that the player does not hit the dartboard is,
⇒ 1 / 14
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.
Hence, Number of not hit dartboard is,
⇒ 140 - 105
⇒ 35
Thus, The experimental probability that the player does not hit the dartboard is,
⇒ 35 / 140
⇒ 7 / 28
⇒ 1 / 14

Kelly owns a comic book that is currently worth $840, and she believes that its value will increase by $30 every year. Kelly plans to sell the comic book for $1,500 and wants to know how long she must wait until the comic book's value reaches at least 90% of that amount.
This problem can be solved with an inequality that uses the variable x.
How should x be defined?
x = the number of years until the comic book is worth 90% of $1,500
x = the price Kelly plans to sell the comic book for
x = the current value of the comic book
x = the number of years Kelly has already owned the comic book

Maggie has a rectangular box with a length of 6 1/2 inches, a width of 9 inches and a height of 9 1/2 inches.
What is the volume of Maggies box ?\
Answer:
555 3/4 inches³
Step-by-step explanation:
*To find volume, you just multiply the three lengths together*
1. 6 1/2 x 9 = 58 1/2
2. 58 1/2 x 9 1/2 = 555 3/4
When you do volume, your answer must end in inches "cubed" which is the three that hangs in the air since cubed means to the third power.

1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.
The total number of eggs, y, contained in x cartons can be represented by the equation y = 12x. Which of the following graphs best represents this situation?
Answer:
C
Step-by-step explanation:
let's take the equation apart:
y=12x
12 is the slope
(12 rise over 1 run)
Let's create a table:x y1 12 2 243 36so on...
Based on that, we could determine the answer
Which of the following represents the constant of proportionality in the table below?
The constant of proportionality is the one in option B; k = 95
Which is the constant of proportionality?Remember that a proportional relation can be written as:
y = k*x
Where k is the constant of proportionality.
Here we can define the variables:
x= months.
y= total revenue.
Now we can use any pair of values in the table to get the constant of proportionality. For example if we use the first pair we get:
x = 2
y = 190
Replacing these values we will get:
190 = k*2
190/2 = k
95 = k
That is the constant of proportionality, the correct option is B.

Step-by-step explanation:
The general formula to find the total surface area of a prism is:
Total Surface Area (TSA) = 2 × Base Area + Base Perimeter × Height
TSA = 2 x 0.5 x 0.5 x 0.5
TSA = 0.25
So the surface area of the prism is 0.25cm^2

Micah uses the coordinate grid to draw a rectangle. Three verticles of the rectancle are (-4, 5),(-4,3) and (6,5). What are the coordinates of the fourh vertex? show micahs rectangles on the coordinate grid
Answer:
(6, 3)
Step-by-step explanation:
We already have two coordinates that make one side of the rectangle up.
(-4, 5) and (-4, 3)
Notice how only the y-coordinates change.
So, based on this logic, we should get:
(6, 5) and (6, 3)
So, the missing coordinate is (6,3)
Answer:
(6,3) is the missing 4th vertex.
Step-by-step explanation:
We know that, a rectangle is made up of 4 sides , 4 vertices and 4 edges.
According to the question, there are 3 vertices marked.
The three vertices are:
(-4,5)(-4,3)(6,5)IMPORTANT NOTEIf we are measuring the sides of a quadrilateral on a coordinate grid, we have to remember that each and every point comes twice in adjacent sides.
For example:
In the given figure, (-4) and 5 appeared twice in the three given vertices.
Now, we should remove (-4) and 5 from the three vertices.
We will be left with 6 and 3.
So, the 4th point will be the combination of 6 and 3.
Hence, we will get the 4th point as (6,3).
Hope my answer helps you ✌️
