the gfc of 4800xy^3 , 1600y
The GFC of 4800xy³, 1600y is 1600y.
What is GFC:The greatest positive integer that evenly divides into all of the numbers with zero residual is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.
To find the GFC of a given number we will write them as a product of their prime factors.
Here we have
4800xy³ , 1600y
Write the given number as a product of prime numbers
4800xy³ = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 5 × 5 × x × y × y × y
1600y = 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × y
Now list out the highest common factors
[ Here we will list out the factors which are common in both lists]
=> 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × y
=> 1600y
Therefore,
The GFC of 4800xy^3 , 1600y is 1600y

In the given question, the following data reflects the overall enrollment in 10 universities of the open skies state in 2019:
23, 14, 27, 35, 7, 16, 25, 23, 35, 21.
We have to compute the mean.
As we know that;
A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.
To find the mean we firstly add the given data then we divide the sum of data by the total number of data.
Mean = Sum of all data/ Total number
Mean = 23 + 14 + 27 + 35 + 7 + 16 + 25 + 23 + 35 + 21/10

What is the mathematical ratio?
Definitions: When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. For instance, you could express the ratio as 1: 3 if there is 1 guy and 3 girls
Given that:
Everglades Elementary school Purchases 125 fourth grade math's textbooks and 191 fifth grade math's textbooks
Total textbooks = 125 + 191 = 316 books
A box can contain maximum = 28 books

For dinner one night, the

soda was $3. If each
member of the family
had a soda and one slice
of pizza, how much did one
slice of pizza cost?
Humans are drawn to foods that are fatty, sweet, rich and complex. Pizza has all of these components.
What is the description of pizza?Pizzeria is another word for a pizza restaurant or pizza parlor – a place where pizzas are made, sold and served to customers. The term pizzeria comes from the product, pizza, and the suffix, -eria, which translates from italian to “place of” in english. Together, pizzeria means “place of pizza”.pizza, dish of Italian origin consisting of a flattened disk of bread dough topped with some combination of olive oil, oregano, tomato, olives, mozzarella or other cheese, and many other ingredients, baked quickly—usually, in a commercial setting, using a wood-fired oven heated to a very high temperature—and served hot .If we use the variable p to represent our pizzas and s to represent our sodas, if our first equation states than 8 slices of pizza and 5 sodas cost $36.50, that's 8p + 5s = 3650.Notice that I expressed cost in terms of cents so
that we can avoid having to deal with decimals.
In our second equation, 4 slices of pizza and
10 sodas cost $37, that's 4p + 10s = 3700.
Now let's rewrite our two equations on top of one another.
8p + 5s = 3650
4p + 10s = 3700
To solve this system of equations, I would use addition.
I would multiply the bottom equation by -2
to create a situation where our p's will cancel.
When we do that, we get -8p - 20s = -7400.
Now rewrite the equations once again ~
8p + 5s = 3650
-8p - 20s = -7400
Now add the equations together.
So we have -15s = -3,750.
Divide both sides by -15 and s = 250.
Remember that I expressed cost in terms of cents so
since s = 250, it really means that a soda is $2.50.
Now just plug an s back in for the s in one equation.
When we do this, we find that p = 300.
So a pizza is $3.00

Approximately when will the object be 6 inches above the rest position? Round to the nearest hundredth, if necessary.
The time at which the object is 6 inches above the rest position will be 4.62 seconds.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
An item is connected to a spring that is extended and delivered. The condition d= - 8cos [(π/6) t] the distance, d, of the item creeps above or underneath the rest position as an element of time, t, in a flash.
d= - 8cos [(π/6) t]
If d = 6, then the value of the variable 't' is calculated as,
6 = - 8cos [(π/6) t]
- 3/4 = cos [(π/6) t]
cos [(77/100)π] = cos [(π/6) t]
Compare the angle, then we have

An Article is bought for Rs 300 and sold for 315. Find the profit and profit percent
Note Please Solve the Question Properly
Answer: PROFIT= 15
PROFIT PERCENT(%)=5%
Step-by-step explanation: As the article is bought at 300 and sold at 315, the difference between the buying and the selling prices is the profit.
Profit is the margin between the price you have bought and the price at which you have sold.
That is 315-300= 15
Now the percentage 15/300*100 = 5
To know the percentage, we have to divide the given value by the total value and after that multiply the result by 100.
Here the given value which is profit is 15 and the total is 300

The linear equation that is parallel to 8x - 10y = -2 and contains (1, -2) is:
4x - 5y = 14
So the last option is the correct one.
Which of the following equations is parallel to 8x - 10y = -2?Remember that two linear equations are parallel only if both lines have the same slope (or coefficients if it is written in standard form) and different y-intercept.
Here our line is:
8x - 10y = -2
If we divide all the equation by 2, we will get:
(8x - 10y)/2 = -2/2
4x - 5y = -1
So any equation of the form:
4x - 5y = c, where c ≠ -1
Is parallel to 8x - 10y = -2
Now we want our line to pass through (1, -2), replacing these values in our line we get:
4x - 5y = c
4*1 - 5*-2 = c
4 + 10 = c
14 = c
Then the linear equation is:

Consequently, it would take roughly 690,64 years for the disintegrations to disappear.
What is disintegrations?Disintegration occurs when a whole entity breaks up into smaller pieces or simply vanishes. Disintegration is the breakdown, fragmentation, or spontaneous disintegration of something. Knowing that integration brings things or people together will help you to understand that disintegration refers to things breaking apart.
Here,
The formula for this is Activity = decay constant x atoms.

decay constant is equal to 4.76 x 10-8 min-1.
Currently, the disintegrations are being slowed to 809 disintegrations per minute.
Ln(809) = Ln(2.64 x 1010) - Ln(4.76 x 10-8 x t)

In this question we have been given a philosophy professor assigns letter grades on a test according to the given scheme.
We need to find the numerical limits for a b grade.
b: scores below the top 12 % and above the bottom 63 % which means scores between the 63th and 88th percentile.
Given that the scores on the test are normally distributed with a mean of 72 and a standard deviation of 8.1
μ = 72, σ = 8.1
z-score at the 63th percentile: 0.332
z-score at the 88th percentile: 1.175
The lower limit of a 'b' grade is:
0.332 = X - μ/σ
0.332 = (X - 72)/8.1
2.67 = X - 72
X = 74.67
X ≈ 75
The upper limit of a 'b' grade is:
1.175 = X - μ/σ
1.175 = (X - 72)/8.1
9.52 = X - 72
X = 81.52
X ≈ 81
Therefore, you get a 'b' if you have a grade between 75 and 81

What is function?
A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output.
A function is defined as a relation between input values and output values. The set containing input values is called domain, and the set containing output values is called range.
The most important characteristic of functions (which define them) is that an input value can't have two difference output values. Having said that, notice that sets B and D have pairs that don't follow this rule.
Therefore, the right answers are A and C, because each input value has only one output value.
