Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
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

Answer question 17 and I will give you brainlest. The second photo is what you need to use to answer the question.
Answers
Answer: 23°
Step-by-step explanation:
First, we need to find the missing angle to the left of x
Let's take what we are given
which is 130°, As you notice the angle of 130° is on a straight line
A straight line is supposed to equal 180°
So we can take 180°-130° which will equal 50°
Now we know that the missing angle next to x is 50°
Now we need to take 107° and add it to 50
Which will equal 157°
Now to get x, we need to take 180°-157°
Which will equal 23°
x=23°

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!

John and 4 friends are going out for pizza for lunch . They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50. Write an equation to model the situation, and find the cost of one large drink.
Answers
Answer:
The cost of one large drink is $1.50.
(13.5-10) + 4 = (7.5 ÷ 5) = $1.50
Step-by-step explanation:
The first step is to minus the $10.00 from the $13.50, which gives us $3.50.
13.5 - 10
We've done this because the pizza is irrelevant to what we're trying to figure out, so we subtract the price of the food, which as we already know is $10, to isolate the price of the 5 drinks to make it easier to find the price of just one.
Once we've done that, we're going to add on the $4.00 they got discounted to the $3.50 in order to find the original price of the drinks without using the gift certificate.
(13.5 - 10) + 4
This gives us $7.50, or the price of 5 large drinks. But we're only looking for the price of one. So we're going to divide the 7.50 by the total number of drinks ordered.
(13.5-10) + 4 = (7.5 ÷ 5)
This gives us 1.5, or $1.50.
(13.5-10) + 4 = (7.5 ÷ 5) = $1.50

- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.

Are the ratios
25/45
and
15/27
proportional? Explain.
Answers
Answer:
Yes
Step-by-step explanation:
First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).
First ratio becomes (25:5)/(45:5) = 5/9
Second ratio becomes (15:3)/(27:3) = 5/9
Since we can simplify them in that way that both are the same that means they are proportional.
because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
Answer:
Yes
Step-by-step explanation:
If you divide 25/45 by 5 you get 5/9
Then you divide 15/27 by 3 you also get 5/9
Since both are equal to 5/9 they are proportional.

Answer with a proper explanation
Answers
Answer:
15 sides
Step-by-step explanation:
As we know the full angles of a polygon is 360°
And
Each side has angle 24°
So,
n = 360/24
n = 15 sides
I hope my answer helps you.
The polygon has 5 sides.
Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.
=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
Find an ordered pair , x y that is a solution to the equation. 5x-y=9
Answers
Answer:
(1, -4)
Step-by-step explanation:
In order to find a solution to a linear equation, we can substitute any value for one variable, simplify the equation, and find the value of the other variable to find a solution that is an ordered pair.
Since any value for either variable will do, we can choose something simple, such as 1. I chose to substitute 1 for x into the equation, as seen below.
\(5x-y = 9\\5(1)-y = 9\)
Now, all I need to do is solve and isolate y:
\(5(1)-y = 9\\5-y = 9\\-y = 4\\y =-4\)
So, with this linear equation, when x equals 1, y equals -4. Thus, a solution to the equation is (1, -4).

Answers
Answer:
0.32 (rounded to the nearest hundredth)
Step-by-step explanation:
If you have any questions ask me please! :)
Answer:
0.32 km
Step-by-step explanation:
Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:
r = 2 km / (2 * 3.14)
r = 2 km / 6.28
r = 0.31847133758 km
Rounding this to the nearest hundredth gives:r ≈ 0.32 km
Therefore, the approximate radius of the circle is 0.32 kilometers.
