Answer:
277g / 40cm³
Step-by-step explanation:
Density = mass / volume
In this case:
volume = 8cm*5cm*4cm = 160cm³
then:
Density = 1088g / 160cm³ = 544g/80cm³ = 277g/40cm³

Calculate the distance between the points N=(-8, -2) and C= (-3, 1) in the coordinate plane
Give an exact answer (not a decimal approximation).
34 is incorrect
Answer: 8
Step-by-step explanation:
starting from the x coordinates, -8 and -3, subtract them and get 5. Moving on to the y coordinates, -2 and 1, you add 2 and 1 to get 3. In total after adding 5 and 3 you get 8. When the coordinates (that are in the same spot) are the same, you are subtract. But when they are different, you add. Sorry if this is confusing! But in the end, 8 is he answer.
For the universal set, u= (5, 6, 7, 8, 9) , complete the parts below.
Write your answers in roster form or as .
Given the subset A, the complement of A, A' is {6}
Given the complement of C, C is {5, 7, 9}
What are the answers in roster form?The universal set contains all the elements of the subsets. ' means complement = it means elements that are not in the subset but in the universal set.
To write a set in a roster form, the elements in the set are written in a row within curly brackets - { }. The elements in the set are then separated by commas.
A' = {6}
C = {5, 7, 9}

determine the range of the following graph. PLEASE HELP MEEE
Answer:
-5 ≤ y ≤ 5
Step-by-step explanation:
Hello!
The range is the set of y-values that the graph passes through.
Since the endpoints of the graph are filled in, meaning they include the values they end on, we use the ≥ or ≤ symbols to write the inequality for the range.
The minimum y-value is -5, and the maximum y-value is 5.
The inequality for the range would be -5 ≤ y ≤ 5.

150 is 96 percent of what number
Answer:
Step-by-step explanation:
Comment
Let the unknown number = x
You should try and figure out if x is bigger than 150 or less than 150.
The equation will tell you.
96/100 * x = 150 96/100 = .96 So you will get something larger than 150 for x
Combine
96/100 = 0.96
Equation
.96*x = 150 Divide by 0.946
.96x/.96 = 150/0.96
Answer
x = 156.25
And as predicted, the answer is larger than 150, because you were dividing by a number less than 1

We have data on the weights in grams of 5 baby pythons. Their mean weight is 31.8 and the standard deviation of the weights is 2.79 . The correct units for the standard deviation is Grams.
According to the question statement, We have data on the weights in grams of 5 baby pythons. Their mean weight is 31.8 and the standard deviation of the weights is 2.79.
The correct units for the standard deviation is Grams because the unit of standard deviation is the unit of simple data and the unit of variance is the square of the simple data unit.
And as we know the unit of weight is Grams only hence we conclude that Grams is the correct unit of standard deviation.
Standard Deviation: Abbreviated as SD and standard deviation is a measure of the amount of variation of a set of values. A low standard deviation indicates that the values tend to be close to the mean (expected value) of the set, while a more or high SD indicates that the values are spread out over a wider range.To learn more about standard deviation, click on the given link below

A recent study of 50 U.S. chess players details such things as the number of years the players have been active and the chess ratings of the 50 players. (A chess rating is a number, with a higher number indicating greater expertise.) The chess rating data for the sample of 50 players are summarized in the following histogram.
Using the given histogram, we have that 90% of the players in the sample have scores that are less than 2300.
What is the missing information?This problem is incomplete, but researching it on a search engine, we have that the histogram states as follows:
6 of these players have scores between 300 and 700.6 of these players have scores between 700 and 1100.13 of these players have scores between 1100 and 1500.14 of these players have scores between 1500 and 1900.6 of these players have scores between 1900 and 1300.5 of these players have scores between 2300 and 2700.It asks the proportion of players in the sample with scores that are less than 2300.
What is an histogram?An histogram is a graph that shows the number of times each element of x was observed.

Erin charged $900 on the current credit card this billing cycle. Erin pays $300 towards the balance by the due date, but is unable to pay the remaining $600. The balance of $600 carries over to the next billing cycle, but he must pay interest on this amount as well. If the APR is 15%, how much interest will be added to the payment for the next billing cycle?
$690 is the next bill payment will be added for the next billing cycle.
What is rate of interest ?
An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
Total payment charged = $900
amount paid = $300
amount remained = $600
APR on $600 = 15%
= 600*15/100
= 600*0.15
= $90
Therefore, in the next bill total amount charged is 600 +90 = $690

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.The relationships between two or more items are frequently represented by the points on a graph.The graph is compressed vertically, or shrunk, in the direction of the x-axis. If k > 1, the graph of y = k*f (x) is the graph of f (x) that has had each of its y-coordinates extended vertically by the factor k.The function f(x) is defined as |x-4| +1.

Leave your answer in factored form.
There is a 'strike-through' root at -1 and a double root at 2, so the equation is of the form
[tex]y=a(x+1)^3 (x-2)^2[/tex]
Since the y-intercept is 4,
[tex]4=a(0+1)^3(0-2)^2 \implies 4a=4 \implies a=1 \\ \\ \therefore \boxed{y=(x+1)^3 (x-2)^2}[/tex]
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y=1/3x+5
Step-by-step explanation:
Slope-intercept form is y=mx+b, m being the slope and b being the y-intercept. y and x don't need to be specified for this specific problem.
You figure out the slope by using rise over run
you first pick 2 random points on the line and then count how you get from the 1st point to the 2nd point.
Let's say the points are (-3,4) and (0,5).
to get to (0,5) from (-3,4) you count up 1 (rise) and right 3 (run).
that means your slope is 1/3
Your b, or your y-intercept, is just where the slope intercepts the y-axis, so b=5
From there you just plug those into the equation:
y=1/3x+5
