A bag of chips weighs 8 ounces. How many pounds do 20 bags of chips weigh?
How many bags would you need to equal a ton?
Answer:
160 ounces
Which is 10 pounds
And 4410 chip packets will equal about a ton

because 20 x 8 =160
35274/8 = 4409.25
*note 35274 ounces is equal to a ton
Answer:
4000 bags
Step-by-step explanation:
8 x 20 = 160 oz = 10 lb
2,000 lb = 1 ton
16 oz = 1b
2,000 x 16 = 32,000 oz = 1 ton

Now, you will consider Option 1, setting a maximum shower time of 10 minutes.
rer
Assume all students who showered longer than 10 minutes will now shower for
exactly 10 minutes. Assume the rest of the students will shower for the same amount
of time as they did yesterday.
Blake claims Option 1 would result in the class mean going below 8 minutes, but the
class median would not change.
Explain whether you agree or disagree with Blake's claim. Include the class mean and
median that would result from Option 1 in your explanation.
BI
The maximum shower time is an illustration of mean and median, and the conclusion is to disagree with Blake's claim
How to interpret the shower time?The question is incomplete, as the dataset (and the data elements) are not given.
So, I will answer this question using the following (assumed) dataset:
Shower time (in minutes): 6, 7, 7, 8, 8, 9, 9, 9, 12, 12, 12, 13, 15,
Calculate the mean:
Mean = Sum/Count
So, we have:
Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 12+ 12+ 12+ 13+ 15)/13
Mean = 9.8
The median is the middle element.
So, we have:
Median = 9
From the question, we have the following assumptions:
The shower time of students whose shower times are above 10 minutes, is 10 minutesOther shower time remains unchanged.So, the dataset becomes: 6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10, 10, 10
The mean is:
Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 10+ 10+ 10+ 10+ 10)/13
Mean = 8.7
The median is the middle element.
So, we have:
Median = 9
From the above computation, we have the following table:
Initial Final
Mean 9.8 8.7
Median 9 9
Notice that the mean value changed, but it did not go below 8 as claimed by Blake; while the median remains unchanged.
Hence, the conclusion is to disagree with Blake's claim

Stacy performed an experiment in which she rolled a six-sided die multiple times. The results are shown below
Based on the results above, predict the number of times a 3 would be rolled if Stacy performs the experiment a total of 480 times.
Answer:
5/9
Step-by-step explanation:
Let the probability of getting a multiple of 3 is "A"
Let the probability of getting an even number is "B"
Total number of outcomes=36
Total number of favourable outcomes of either a multiple of 3 or an even number are
(1,1) ,(1,2) ,(2,1) ,(1,3) ,(3,1) ,(2,2) ,(1,5) (5,1) ,(3,3) ,(2,4) ,(4,2) ,(2,6) ,(6,2) ,(3,5) ,(5,3) ,(4,4) ,(6,4) ,(4,6) ,(5,5) ,(6,6)
That is we have 20 favourable outcomes
Hence, Probability=\frac{\text{favourable outcomes}}{\text{total number of outcomes}}Probability=
total number of outcomes

Therefore, after substituting the values we get

Step-by-step explanation:
Write the equation of a line in the slope-intercept form that has a slope of 4 and contains the point (4, 12).
Answer:
y=4x-4
Step-by-step explanation:
Hi there!
we are given that a line has a slope of 4 and it contains the point (4, 12)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
As we are already given the slope, we can immediately substitute it into the formula.
Replace m with 4 in y=mx+b:
y=4x+b
Now we need to find b
As the equation passes through the point (4, 12), we can use it to help solve for b
Substitute 4 as x and 12 as y:
12 = 4(4) + b
Multiply
12 = 16 + b
Subtract 16 from both sides
-4 = b
Substitute -4 as b
y = 4x - 4
Hope this helps!

Answer:I think i remember this i think is A.
Step-by-step explanation:
The value of sec θ is -√2 in the interval 3π/2 < θ < 2π, where θ is the angle whose tangent is -1.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We are given that tan θ = -1, and we need to find the value of sec θ in the interval 3π/2 < θ < 2π.
Since tan θ = -1, we know that θ is in the third quadrant, where both x and y coordinates are negative. In the third quadrant, the reference angle for θ is π - θ, so we have:
tan θ = -1 = tan(-π/4)
π/4 = π - θ
θ = 3π/4
Now, we can use the fact that sec θ is the reciprocal of cos θ, and find cos θ in the third quadrant.
In the third quadrant, cos θ is negative. We can use the Pythagorean identity to find cos θ:
sin²θ + cos²θ = 1
Since sin θ is positive and we know that θ is in the third quadrant, we have:
sin θ = -√(1 - cos²θ)
tan θ = sin θ/cos θ = -1
Substituting sin θ and simplifying, we get:
-√(1 - cos² θ)/cos θ = -1
√(1 - cos² θ) = cos θ
Squaring both sides:
1 - cos²θ = cos²θ
2cos²θ = 1
cos²θ = 1/2
cos θ = -√2/2 (since θ is in the third quadrant)
Finally, we can find sec θ:
sec θ = 1/cos θ = -√2
Therefore, the value of sec θ is -√2 in the interval 3π/2 < θ < 2π, where θ is the angle whose tangent is -1.

Step-by-step explanation:
Here we can see that 120° with the right angle is equal to 180° :
120° + right angle = 180°
then:
right angle = 180° - 120° = 60°
The right angle with 5x angle is equal to 180° too ;
